Synthesis Essays: A Step-by-Step How-To Guide

A synthesis essay is generally a short essay which brings two or more sources (or perspectives) into conversation with each other.

The word “synthesis” confuses every student a little bit. Fortunately, this step-by-step how-to guide will see you through to success!

Here’s a step-by-step how-to guide, with examples, that will help you write yours.

Before drafting your essay:

After reading the sources and before writing your essay, ask yourself these questions:

• What is the debate or issue that concerns all of the writers? In other words, what is the question they are trying to answer?
• On what points do they agree?
• On what points do they disagree?
• If they were having a verbal discussion, how would writer number one respond to the arguments of writer number two?

In a way, writing a synthesis essay is similar to composing a summary. But a synthesis essay requires you to read more than one source and to identify the way the writers’ ideas and points of view are related.

Sometimes several sources will reach the same conclusion even though each source approaches the subject from a different point of view.

Other times, sources will discuss the same aspects of the problem/issue/debate but will reach different conclusions.

And sometimes, sources will simply repeat ideas you have read in other sources; however, this is unlikely in a high school or AP situation.

To better organize your thoughts about what you’ve read, do this:

• Identify each writer’s thesis/claim/main idea
• List the writers supporting ideas (think topic sentences or substantiating ideas)
• List the types of support used by the writers that seem important. For example, if the writer uses a lot of statistics to support a claim, note this. If a writer uses historical facts, note this.

There’s one more thing to do before writing: You need to articulate for yourself the relationships and connections among these ideas.

Sometimes the relationships are easy to find. For example, after reading several articles about censorship in newspapers, you may notice that most of the writers refer to or in some way use the First Amendment to help support their arguments and help persuade readers. In this case, you would want to describe the different ways the writers use the First Amendment in their arguments. To do this, ask yourself, “How does this writer exploit the value of the First Amendment/use the First Amendment to help persuade or manipulate the readers into thinking that she is right?

Sometimes articulating the relationships between ideas is not as easy. If you have trouble articulating clear relationships among the shared ideas you have noted, ask yourself these questions:

• Do the ideas of one writer support the ideas of another? If so, how?
• Do the writers who reach the same conclusion use the same ideas in their writing? If not, is there a different persuasive value to the ideas used by one writer than by the other?
• Do the writers who disagree discuss similar points or did they approach the subject from a completely different angle and therefore use different points and different kinds of evidence to support their arguments?
• Review your list of ideas. Are any of the ideas you have listed actually the same idea, just written in different words?

How to Write a Synthesis Essay

4-minute read

• 31st May 2023

Are you writing a synthesis essay? This is a paper that combines information from a variety of sources to form a new idea. Essentially, you’re synthesizing existing concepts and arguments to create something original.

As a student, you’ll probably have to write a synthesis essay at some point. Read on for our step-by-step guide on how to write one effectively.

Step 1. Define Your Idea or Argument

If you haven’t done so already, decide on a topic to write about. Read up about it using a variety of credible sources and make detailed notes while you research. Make sure you keep track of the sources you decide to pull information from so that you can cite them properly later.

Make a list of key points from your research. Once you have a good selection of material to work with, start developing your own idea or argument. This will be the focus of your essay.

Step 2. Create an Outline

Synthesis essays generally follow this format: an introduction, a handful of main body paragraphs, and a conclusion. It’s a good idea to come up with an essay plan before you start writing so that you can keep things organized while you work.

The outline is mainly helpful for deciding what to include in your body paragraphs. Decide what supporting points (and counterarguments ) from your research you want to include, and which order you want to discuss them in. You should have enough information to flesh out one paragraph for each point.

Step 3. Write Your Introduction

In your introduction, you should open with something that hooks the reader and captures their attention. Then, state your argument or idea (i.e., your thesis statement) and briefly summarize the material you’ll be including in your essay. You should also include any relevant background information here.

Step 4. Write the Body Paragraphs

Using your outline, discuss each point from your source material in more depth, devoting a body paragraph to each. Explain the information from the outside source, including appropriate citations, and discuss how it connects with your idea.

It’s a good idea to mostly focus on points that support your argument, but you should also include a paragraph with a counterargument or two. This means discussing a perspective that doesn’t necessarily align with your idea, and then explaining why your argument still works.

Step 5. Tie It All Together With a Conclusion

The conclusion should leave the reader feeling convinced of your idea. Restate your point clearly and summarize the main points you’ve discussed. You could also offer any concluding reflections on the topic.

Different Types of Synthesis Essays

While you can follow our steps for any type of synthesis essay, yours will probably fall under one of two categories: explanatory or argumentative.

Argumentative essays are as they sound – they present an argument. With an argumentative essay, you’ll take a more definitive stance on something and use your supporting material to persuade the reader.

Explanatory essays don’t necessarily take a side one way or the other. Rather, they focus on developing and explaining a concept thoroughly. Knowing which type of essay you’re writing will help you to gather more effective source material for your purpose.

Cite Your Sources

Since synthesis essays are particularly dependent on outside material, it’s especially important that you cite your sources correctly. Familiarize yourself with your referencing system before you start researching so you know what information you need to keep track of, and include appropriate citations whenever you use someone else’s work.

At the end of the essay, you’ll need to compile your sources into a reference list following the requirements of your style guide.

Summary: Writing a Synthesis Essay

Hopefully, this post has helped you to feel more confident in writing a synthesis essay. Choose a topic first, do your research, keep track of your sources, and develop an argument or idea. From there, you can organize your thoughts into an outline and get to writing!

📚 What Is a Synthesis Essay?

A synthesis essay is an assignment that requires a unique interpretation of a particular topic using several reliable sources. To write it, you need to understand, analyze, and synthesize information. That is why this type of essay is used in the AP Lang exam to assess students’ reasoning skills.

The key features of the synthesis essay are:

• Debatable topic . If your goal is to write a good synthesis essay, it’s necessary to choose an arguable topic. It’s best to choose something that people have different opinions about. This will allow you to use many sources with various viewpoints for your synthesis.
• Clear thesis statement. It’s a sentence that briefly describes the main idea of your essay.
• Reliable sources to prove your thesis . For a synthesis essay, your opinion is not enough. You also need to find the evidence. Keep in mind that simply reading an online encyclopedia won’t do; make sure to choose only reliable sources.

What Does It Mean to Synthesize Information?

Synthesis is a process that has huge importance in nature, science, and our everyday life. The word stems from Ancient Greek “synthesis,” which means “putting together.” In general, synthesis is the combination of components to form a connected whole.

In everyday life, we usually resort to it to synthesize information . This means taking the data from different sources and bringing it together. This process is the opposite of analyzing:

• For an analysis , you break problems into pieces,
• For a synthesis , you combine separate elements into a whole.

We use synthesis for analysis papers, research papers, argument papers, and business reports.

What Does Synthesis Mean in Writing?

Synthesis in writing means summarizing and connecting different sources considering a particular topic. Although synthesis and analysis are two opposite things, they usually go together in synthesis essays. The process consists of 2 stages:

• Conduct the analysis. For that, you break down a problem into parts and analyze the sources. It’s helpful to highlight everything regarding your topic while reading.
• Carry out the synthesis. The next step is to formulate an opinion and combine the highlighted information from the sources.

Synthesis is not only used in writing but also in reading comprehension . It’s useful to do this kind of reading while studying your sources. There are three reading comprehension stages:

• Your previous knowledge about the topic.
• Expansion of your knowledge while you are reading.
• Understanding of the problem when you have finished reading.

So, synthesized reading comprehension means combining three stages in one and formulating one statement.

Synthesis vs Summary: What Is the Difference?

A summary is a paraphrasing of the written source in your own words. For a good summary, it’s necessary to include all of the text’s key elements. Meanwhile, synthesis means combining different ideas from different sources. You don’t have to include all the key points; just choose everything related to your topic.

Both of these techniques are used for the synthesis essay:

• The summary goes in the conclusion. You briefly sum up your paper’s main ideas.
• Synthesis goes in the body paragraphs. Here, you combine multiple sources to prove a point.

📝 Synthesis Essay Types

There are two main types of a synthesis essay: argument and explanatory synthesis.

Both of them require working with multiple reliable sources and analyzing information. The only difference is that an argument synthesis essay requires your own opinion, while an explanatory synthesis essay does not.

Argument Synthesis Essay: Outline and Definition

As you already know, an argument synthesis essay requires you to state your own opinion about the given topic and back it up with several reliable sources. The purpose of such an essay is to persuade the reader that your point is correct.

Here’s what an argument synthesis essay consists of:

Explanatory Synthesis Essay: Definition and How to Write

An explanatory informative synthesis essay requires you to stay neutral towards the problem you are discussing. This means you cannot express your own opinion considering the given question or a problem. Your task is just to inform the reader. That’s why this essay type is also called informative synthesis.

Check out this explanatory essay outline:

✅ How to Write a Synthesis Essay Step by Step

When it comes to the synthesis essay outline, it’s not too different from other assignments. Have a look at this template:

How to Synthesize: Working with Sources

After you’ve decided on your topic, it’s time to figure out how to synthesize articles into one text. This is how you do it:

• Choose reliable sources: the ones printed in journals or published on academic websites.
• Become familiar with them and see if they fit into your essay.
• Try to find a few sources for each point. It will increase your essay’s reliability.
• Relate each source to your arguments and see similarities between them.
• Don’t forget to list every source in the references.

When you are done with a comprehensive analysis of related literature, try to step back and imagine a person who has a different opinion on this topic. Think of some arguments that they can provide to prove their opinion. After you have the list of arguments, find the written evidence of why they are wrong and put them in your essay.

Analyzing and organizing sources is the first and very important step for the synthesis essay. So make sure you do understand what the text means before using it as a reference.

Synthesis Essay Outline: How to Write

For structuring your essay, it’s useful to try mapping . This technique means combining the information from different sources and rearranging it to create a new direction. To do it, you need to analyze the authors’ ideas and come up with your own conclusions.

The best way to do that is called synthesis matrix or graphic organizer. It’s a chart that you can make when you start working on your essay. Here you have a horizontal column that states the main ideas and a few vertical columns that present sources. Your task is to take sources you have chosen and write down the main ideas from them.

Here’s an example of a matrix chart:

While doing that, you will see how many sources contain the same ideas. When you analyze them, you will be able to formulate your thesis backed up with evidence. The synthesis matrix also helps to see new arguments you can cover in your synthesis paper.

How to Write an Introduction for a Synthesis Essay

Now it’s time to start writing the paper. In the introductory part of the essay, you can include:

• A short yet catchy sentence or a quotation that would present the topic. The start of your essay should make people interested. It’s best to make the first sentence not only informative but also easy to understand.
• The texts that are used for the essay. Provide the titles and the authors’ names (use the appropriate guidelines depending on the writing style.)
• The background information which is needed to understand your essay. Definitions of terms or unknown words considering the topic can be included in this part. Otherwise, people may find it hard to understand what they are reading about.

How to Write a Thesis for a Synthesis Essay

A thesis statement is a point of view on a certain problem that you will defend in your essay. It should contain the key points that you want to include in your paper. Here’s how to create a perfect thesis statement:

• Find several central ideas in the chart.
• Choose the ones that are repeated the most often and the ones that you feel need to be in your essay.
• Combine them, and you have a thesis statement with all the key points.
• Make a draft of the thesis statement. Try to formulate the main idea you want to present in your essay.
• Elaborate on this idea. Add some details and expand it a bit further.

If the whole picture is coherent, and it conveys exactly what you wanted, then this is your perfect thesis statement. See the example below:

Gender inequality still exists at the workplace: women are less likely to get the most responsible positions, easily lose careers due to maternity leave, and often receive less pay for the same amount of work.

How to Write Synthesis Paragraphs for the Main Body

Your essay’s main body consists of a few paragraphs. Each of them presents a different argument considering the topic. When you start a paragraph, make sure to begin with a topic sentence, which informs the reader about the paragraph’s main idea. Then, include the synthesized sources and elaborate on them.

Here’s what you should and shouldn’t do when writing the main body:

You can use the following words to present the ideas from your sources. They will help you reflect the authors’ tone:

How to Conclude a Synthesis Essay

There are quite a few ways to conclude the synthesis paper. Have a look at some of the options:

• Paraphrase the thesis. As you remember, the thesis is the main idea of your essay. The conclusion is a good place to remind your readers about it. When they are done with the reading, they remember the most important thing from your essay.
• Synthesize the arguments. There is no need to repeat everything you wrote in your essay. Just briefly summarize the most crucial points.
• Answer the “So what” question. Tell the readers why this topic matters, why you’ve chosen it, and why it’s valuable for the reader.
• Provide a closure. It’s an effective strategy when you want to make the reader think. Leave them with a strong statement at the end of your essay.

Synthesis Paper Proofreading Tips

When you have finally written your paper, there is still one important thing left to do. You need to check your paper for any grammatical and contextual mistakes. You certainly can do it yourself, but it would be perfect if you could ask somebody else to read it.

The first thing you need to check grammar-wise is the tense you are using. There is no single tense you need to use for the synthesis essay. It depends on the format:

• If you’re writing in MLA format, use the present tense;
• For APA essays, you use the past tense.

The next step is to check whether your synthesis essay has everything that’s required. For that, we have prepared the checklist of questions you can ask yourself to proofread your essays.

• Is there a clear thesis statement?
• Did you include all of the key points from the synthesis?
• Are there clear transitions between paragraphs?
• Did you organize a paragraph around a single idea?
• Did you use reliable and up-to-date sources?
• Did you analyze sources rather than just summarize them?
• Did you mention every source you’ve used?

If you’ve answered “yes” to all the questions—congratulations, you are done with the essay! Otherwise, you need to come back and fix everything that you’ve answered “no” to.

Let’s get started.

On This Page On This Page -->

What is a Synthesis Essay?

Synthesis essay definition states:

It is a piece of writing that takes a unique perspective on a central idea, topic, or theme. Then backs it up with evidence from multiple sources.

A synthesis essay is an important part of academic writing. The main purpose of this essay is to show your ability to prove an argument.

To make sense of these arguments, you need to use different credible sources. It demonstrates your basic understanding of the main subject. This type of essay help to enhance your critical, analytical, and research skills.

A synthesis essay is made up of ideas and conclusions based on the information reviewed. Also, this essay asks you to summarize the topic and add your own thoughts about it in relation to what you have read.

Furthermore, the synthesis essays can be similar to analytical essays , argumentative essays , or compare and contrast essays .

Synthesis Essay Types

There are three types of a synthesis essay:

1. Argument Synthesis Essay

This essay's purpose is to debate or argue on a certain topic or issue. It justifies its claims by providing evidence in the body of the essay.

In contrast to the explanatory essay, you will perform the same thing as if you were writing a typical argumentative paper. First, state your argument, make supporting statements, and back up each claim with reliable facts.

2. Review Essay

A review essay is frequently written as a preparatory essay to an argument synthesis. Review essays are commonly used in social science and medicine classes.

It is a discussion of what has already been published on a topic, with a critical examination of the sources mentioned.

An unwritten thesis statement is added to it, which is not final and indicates that further study is needed in that area.

3. Explanatory Synthesis Essay

In this essay, the writer helps the reader to grasp deeper knowledge about the topic. Rather than arguing or debating on some points, the goal of this essay is to explain a certain topic.

Like any other essay, it needs backing up with supporting claims and credible sources.

How to Start a Synthesis Essay?

The following are some helpful techniques for writing an essay. These will help you start the process and avoid common errors that plague many writers.

1. Choosing a Synthesis Essay Topic 

A prompt for a synthesis paper must be arguable. Based on your project, you may be required to select primary content. Select a book that may include contrasting perspectives. Here are some important tips for choosing a topic for a synthesis essay.

• Look through the themes and ideas. Read from sources and investigate specific topics thoroughly to see if any of them catch your interest.
• Select a topic and collect relevant and valuable references for your synthesis paper.
• Outline your synthesis essay using concepts or ideas from the sources. This should make writing a lot simpler and save you a lot of time.

It is necessary to find an arguable topic to make your synthesis essay effective. Another reason is that these topics have been discussed in public for decades. 

Examples of good synthesis essay topics are;

• The process of hiring in the age of social media
• Social networks promote suicide
• Should higher education be free?
• Is it necessary to remove marks in education 
• The importance of getting a good education
• 3D printers are not used efficiently nowadays.
• Is technology really helping people?
• Why has technology made surgery safe and effective?
• What is the cause of widespread obesity in teens?
• What is the role of gender today?

2. Analyze Your Topic

Here's how you can fully understand your synthesis essay topic.

• Grasp the Idea of a Synthesis Essay

A synthesis essay's purpose is to establish meaningful connections between sections of a work. When conducting research on a topic, you have to look for connections to build a strong viewpoint on the subject. The ultimate goal of the essay is to present and prove a claim about a topic .

• Select a Topic Appropriate for a Synthesis Essay

The subject and topic must be extensive enough to include multiple relevant sources. If you have a free hand in deciding what to write about, some preparatory research may assist you in researching and choosing the right topic. 

•  Select and Study Your Sources Carefully

Research and find relevant information and sources. Generally, choose at least three references for your essay. It's a good idea to learn one or two additional sources for better understanding but no matter what it is, make sure that you study it properly.

Remember that it is better to read three sources properly than five sources poorly.

Compile each source by writing notes in the margins. This allows you to keep track of your thoughts, fresh ideas, and so on. 

Paper Due? Why Suffer? That's our Job!

• Reread the Source Material 

Reread your source material for elements that will help to support your argument. 

Examine your sources for important statements, figures, thoughts, and facts that support your thesis. Make a note of them when you come across them. This will be very useful throughout your writing process. 

3. Develop a Thesis Statement 

Your thesis statement will be the central idea of your essay. It should cover the topic and express your viewpoint on it. After reading the sources and conducting your research, form an opinion on your topic. 

It should be stated as a complete sentence. Based on the essay, your thesis statement could be the first sentence of the essay or the last sentence of the first paragraph.

• Structure Your Thesis Statement Creatively 

To present your thesis, use a more creative structure. You can use a more elaborate structure than the one outlined above. You can develop your essay using the following approaches:

Straw man: In this approach, you will present the counter-arguments first. Then demonstrate their weaknesses and flaws. 

Such an approach demonstrates your awareness of the opposition as well as your readiness to respond to it. You present the counter-argument immediately following your thesis statement, followed by evidence to refute it. And conclude with a positive argument that supports your thesis.

Concession: In structure, concessions in essays are similar to the straw man. But this approach acknowledges the validity of the counter-argument while demonstrating that your argument is stronger. This structure is suitable for presenting papers to readers who hold opposing views. 

Illustration/ Example: It could be a thorough narrative, synopsis, or quotation from your source material that provides support for your position. However, you should not make your paper a collection of examples at the expense of supporting your thesis statement.

Comparison and Contrast: In this approach, similarities and differences between two subjects or sources demonstrate both aspects. It requires a thorough reading of your source material to identify both subtle and major points of comparison.

This type of essay can present its arguments source by source or by points of similarity or difference.

4. Create an Outline for Your Essay

An essay outline is a method for outlining the framework of your essay. Here’s what you have to do. Outlining can help you structure and plan your synthesis paper. 

The standard outline of a synthesis essay is divided into three sections:

How to Write a Synthesis Essay?

For writing a great essay, you have to do extensive research on your subject. This essay connects sections of multiple works and develops a strong viewpoint on a subject.

There are some major steps of the process:

1. Start Writing Your Essay 

After getting done with the preparation part, start to write your synthesis essay. 

2. Write Your First Draft Using Your Outline as a Guide

But be prepared to change your strategy if you discover fresh ideas and information. And make sure it supports your thesis and the source material. 

Your essay should have an introduction paragraph with your thesis statement at the end of it. A body with evidence that supports your main topic and thesis statement. Lastly, a conclusion that summarizes your point of view.

3. Use Transitions 

To make the content flow logically, use transitions between paragraphs. Transition words are an excellent method to highlight areas where your sources complement one another. 

Longer quotes of three lines or more should be presented as block quotes to draw emphasis to them.

4. Wrap Up Your Essay 

Here you have completed the writing process, but still, you need to make sure that your essay is flawless. 

5. Revise Your Essay

This is the time to enhance transitions between points and paragraphs and to reinforce arguments. You should strive to make your argument as concise and clear to understand as possible. It is beneficial to read your essay aloud so you can spot problematic phrases or unclear ideas.

Request someone else to proofread your paper. Have you heard the cliché "two heads are better than one"? Is it still valid?

Ask a friend or coworker what they would add or eliminate from the paper. Most importantly, does your thesis statement make sense, and are your references clearly supporting it?

Answer these questions in your essay.

6. Proofread Your Content

Examine your document for any grammatical, punctuation, or spelling mistakes. 

Are all the terms, names, and words accurately spelled? Are there any extraneous English language or sentence fragments? As you go, correct them.

Read the essay loudly to ensure that you don't accidentally add or remove words when reading in your mind. If possible, ask a friend or classmate to edit your writing.

7. Must Cite Sources

Use footnotes to mention information in the body paragraph and bibliography of cited books at the conclusion. Footnotes and in-text citations should be used for any information that is quoted, paraphrased, or cited.

8. Title Your Essay 

The point of view expressed in your thesis statement and supporting arguments should be reflected in your title. Therefore, choose a title that suits your essay rather than constructing your essay to fit the title.

Synthesis Essay Format

The format of your synthesis paper is chosen by your high school, college, or university professor. MLA, APA, and Chicago styles are the most often used styles.

The APA format is followed in the disciplines of science, education, and psychology. Chicago is commonly followed in the field of history, fine arts, and business. And MLA is the style of citation used in the humanities.

APA Style Format

The following are some APA style important details:

• Add a page header to the top of each page.
• Times New Roman, 1” margins, 12 pt. Font, double-spaced.
• The format of a synthesis essay should be separated into four sections: title page, abstract, main body, and references.
• Insert a page number in the upper right corner.

Chicago Style Format

The following are some Chicago style key points:

• Use double-spacing between the paper's lines.
• Make margins of one inch.
• Font size: 12 pt. Times New Roman font style.
• Create text that is left-justified with a rugged edge.
• Mention the full name of a person, place, or organization.
• At the start of the paragraph, use half-inch indents.
• The bibliography should be on its own page.

MLA Style Format

The following are some MLA style significant points:

• The title must be centered.
• Font: Times New Roman, 1” margins, 12 pt font size, double-spaced
• Mention your name, professor's name, the course number, and the date (dd/mm/yy).
• On each page, the top right corner displays the last name and page number.
• The final page provides a “Works Cited” list.

Synthesis Essay Rubric

A rubric is essentially a list of criteria that your professor will use to grade your paper. 

Knowing how each criterion is weighted can help make sure you get the best grade possible on your synthesis essay. 

The Basics of the Synthesis Essay Rubric

The basic elements of any synthesis essay rubric include organization, focus/development, and language use/style. 

• Organization refers to how well you structure your paper. It should flow logically and have clear transitions between sections. 
• Focus/development looks at how well you develop your argument throughout the paper. Are you able to clearly explain why each point supports your thesis?
• Language use/style focuses on grammar, punctuation, and spelling. Was the paper proofread thoroughly or did careless errors slip in?

For example , your synthesis essay thesis statement is

“Capital punishment should be abolished in all states." 

Do you provide evidence from different angles, such as legal history, religious beliefs, or moral arguments to back up this claim? 

Does this evidence prove why capital punishment should be abolished?

How to Write a Synthesis Essay - Ap Lang

Are you an AP Lang student who’s been assigned the dreaded synthesis essay? Here’s how to write a successful synthesis essay for AP Lang. 

• Understand the Prompt 

The first step in writing any synthesis essay is to read and understand the prompt. It’s also important to note any specific requirements such as word count, formatting style, or sources that must be used in your essay. 

• Organize Your Argument 

Once you have all the information necessary, it’s time to start organizing your argument.

Start by identifying any common themes or ideas between the various sources of evidence and create an outline with these points at its core. 

• Write Your Essay 

Now comes the fun part—writing! 

You should now have a comprehensive outline of all the points and evidence you want to include in your essay. So use this as a guide when crafting your argument. 

Make sure that each point has supporting evidence from credible sources and that everything flows logically from one point to another. 

Finally, don’t forget to proofread and edit before submitting so that there are no errors in grammar or spelling. These small details can make all the difference! 

Synthesis Essay Tips

Working on a synthesis paper requires a thorough study of a particular given prompt. To evaluate it properly, you must first understand the prompt’s goal, argument, author’s claim, and rhetoric.

To compose a successful synthesis essay, here are some helpful tips to keep in mind.

• Use Multiple Reasons

It is well recognized that the use of various reasons (generally two) is a very successful approach.

Present one argument against your strong thesis statement. This type of evidence presents an introduction and description. The advantage of this method is to teach awareness of the other side of the argument. It is followed by the opposing view and a decisive factor.

This is one of the most basic ways of organizing. It enables you to summarise the sources that are most relevant to you. The problem is that this technique excludes any of your individual thinking.

• Compare and Contrast

Comparing reveals similarities, while contrasting reveals distinctions. It is feasible to show an in-depth analysis of your chosen topic. It allows writers to compare and contrast two sources at the same time.

Write quotations from sources in your own words. This approach also allows the usage of quotable sources. Ensure to cite the reference when you use the reference.

This method depicts the opposing point of view. It demonstrates that the positives outweigh the negatives.

• Restate your thesis. 
• Summarize or synthesize key points. 
• Make your argument's context explicit. 

What is a synthesis paragraph?

A synthesis is a textual debate that includes support from multiple sources with opposing viewpoints. This type of work requires analysis by using different sources and determining their relevance to your thesis.

Why is synthesis important?

It is important because it allows us to: 

• Test and validate hypotheses. 
• Comprehend key processes.

What is an example of a synthesis?

Making connections or putting things together is all that is required. We naturally synthesize information to assist others in seeing connections between things. For example, synthesis occurs when you report to a friend what other friends have said about a film or book.

How to Write a Synthesis Essay

Last Updated: April 7, 2024 Fact Checked

This article was co-authored by Christopher Taylor, PhD . Christopher Taylor is an Adjunct Assistant Professor of English at Austin Community College in Texas. He received his PhD in English Literature and Medieval Studies from the University of Texas at Austin in 2014. There are 11 references cited in this article, which can be found at the bottom of the page.

Writing a synthesis essay requires the ability to digest information and present it in an organized fashion. While this skill is developed in high school and college classes, it translates to the business and advertising world as well. Scroll down to Step 1 to begin learning how to write a synthesis essay.

Examining Your Topic

• Argument synthesis: This type of essay has a strong thesis statement that presents the writer's point of view. It organizes relevant information gathered from research in a logical manner to support the thesis' point of view. Business white papers known as position papers often take this form. This is the type of synthesis essay that students will write during the AP test.
• Review: Often written as a preliminary essay to an argument synthesis, a review essay is a discussion of what has been written previously on a topic, with a critical analysis of the sources covered. Its unstated thesis is usually that more research needs to be done in that area or that the topic problem has not been adequately addressed. This type of paper is common in social science classes and in medicine.
• Explanatory/background synthesis: This type of essay helps readers understand a topic by categorizing facts and presenting them to further the reader's understanding. It does not advocate a particular point of view, and if it has a thesis statement, the thesis is a weak one. Some business white papers take this form, although they are more likely to have a point of view, if understated.

• Example of a broad topic narrowed down into a reasonable synthesis essay topic: Instead of the broad topic of Social Media, you could discuss your view on the effects texting has had on the English language.
• If you've been assigned a topic as part of a class, make sure you read the prompt carefully and fully understand it.

• Keep in mind that it's better to do three sources well than to do five sources incompletely.
• Annotate each source by writing notes in the margins. This allows you to keep track of your train of thought, developing ideas, etc.

• Example: Texting has had a positive impact on the English language as it has helped the millennial generation create their own form of the language.

• If you wish to take on a claim by an opponent of your idea, and to poke holes in it, you should also find some ideas or quotes that go against your thesis statement, and plan ways to disprove them. This is called a concession, refutation, or rebuttal, which can strengthen your argument if you do it well.
• Example : For the thesis statement listed above, excellent sources would include quotes from linguists discussing the new words that have developed through 'text-speak', statistics that show the English language has evolved with almost every generation, and facts that show students still have the ability to write with the use of grammar and spelling (which your opponents would bring up as the main reason texting has had a negative effect on the English language).

Outlining Your Essay

• The introductory paragraph: 1. An introductory sentence that acts as a hook, capturing the reader's interest. 2. Identification of the issue you will be discussing. 3. Your thesis statement.
• The body paragraphs: 1. Topic sentence that gives one reason to support your thesis. 2. Your explanation and opinion of the topic sentence. 3. Support from your sources that backs up the claim you just made. 4. Explanation of the significance of the source(s).
• The conclusion paragraph: 1. State further significance of your topic from the evidence and reasons you discussed in the essay. 2. A profound thought or thoughtful ending for your paper.

• Example/illustration. This may be a detailed recount, summary, or direct quote from your source material that provides major support for your point of view. You may use more than one example or illustration, if your paper calls for it. You should not, however, make your paper a series of examples at the expense of supporting your thesis.
• Straw man. With this technique, you present an argument opposed to the argument stated in your thesis, then show the weaknesses and flaws of the counter-argument. This format shows your awareness of the opposition and your readiness to answer it. You present the counter-argument right after your thesis, followed by the evidence to refute it, and end with a positive argument that supports your thesis. [5] X Research source
• Concession. Essays with concessions are structured similar to those using the straw man technique, but they acknowledge the validity of the counter-argument while showing that the original argument is stronger. This structure is good for presenting papers to readers who hold the opposing viewpoint.
• Comparison and contrast. This structure compares similarities and contrasts differences between two subjects or sources to show the facets of both. Writing an essay with this structure requires a careful reading of your source material to find both subtle and major points of similarity and difference. This kind of essay can present its arguments source-by-source or by points of similarity or difference.

• Summary. This structure presents summaries of each of your relevant sources, making a progressively stronger argument for your thesis. It provides specific evidence to support your point of view, but usually omits presenting your own opinions. It's most commonly used for background and review essays.
• List of reasons. This is a series of sub-points that flow from the main point of your paper as stated in its thesis. Each reason is supported with evidence. As with the summary method, reasons should become progressively more important, with the most important reason last.

Writing Your Essay

• Your essay should have an introductory paragraph that includes your thesis , a body to present evidence that supports your thesis, and a conclusion that summarizes your point of view.

• Lengthy quotes of three lines or more should generally be set off as block quotes to better call attention to them. [7] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source

Finalizing Your Essay

• Ask someone else to proofread your paper. The saying “two heads are better than one” still holds true. Ask a friend or colleague what would they add or remove from the paper. Most importantly, does your argument make sense, and is it clearly supported by your sources?

• Read the paper aloud to guarantee that you don't accidentally add in or take out words when reading in your head.
• If you can, get a friend or classmate to proofread your essay as well.

• Example of citing in an AP synthesis essay: McPherson claims “texting has changed the English language in a positive way--it has given a new generation their own unique way to communicate” (Source E).
• For college essays, you'll most likely use MLA format. Whichever format you use, be consistent in its use. You may also be asked to use APA or Chicago style.

• Example title: : English and the iPhone: Exploring the Benefits of 'Text-Speak'

Outline Template

Community Q&A

• Just as your title should fit your essay instead of writing your essay to fit the title, your thesis, once chosen, should direct your subsequent research instead of subsequent research altering your thesis � unless you find you've adopted an unsupportable thesis. Thanks Helpful 21 Not Helpful 8

27 How do I Write a Synthesis Essay?

A synthesis essay is a type of essay that gathers information from a variety of sources to form a new idea, question, or argumentative thesis. Writers composing a synthesis essay will discuss ideas, data, and evidence from a series of sources to either explain or argue something original.

Explanatory vs. Argumentative Synthesis Essays: How Are They Different?

Though the formatting is largely the same, there are two main types of synthesis essays: explanatory and argumentative.

• 1.   Explanatory : The purpose of an explanatory synthesis essay is to use different sources to explain a particular point of view. These synthesis papers objectively examine the similarities and differences between ideas but don’t necessarily choose a side or attempt to sway the reader in any direction.
• 2.   Argumentative : An argumentative synthesis essay follows the same structure as a typical argumentative essay. The thesis of an argumentative essay will argue one specific point.

Synthesis Essay Structure

Synthesis essays typically adhere to the five-paragraph essay structure, but there are slight nuances to structuring this type of essay. Here is how a synthesis essay is structured.

•   Introduction : The foundational ideas of your essay are expressed in the introductory paragraph. You will address the general landscape of ideas around your topic, introducing some of your sources. You will also introduce the argument to be made through a thesis statement, which succinctly states your primary argument in a sentence or two. The thesis statement typically comes at the very end of your introductory paragraph.
•   Body : The body of your synthesis essay is usually about three paragraphs long. This typically includes two paragraphs synthesizing your sources in a way that supports your argument, and one paragraph that acknowledges opposing arguments.
• Conclusion : The conclusion of your synthesis essay reiterates the argument that you’ve made throughout your essay. It may emphasize how each of the points you made and the sources you’ve cited substantiate your point.

How to Write a Synthesis Essay

A great synthesis essay walks readers through a series of ideas and sources to prove or explain a larger point.

Follow this step-by-step guide for writing your essay:

• Choose a topic you’re curious about . Brainstorm a few ideas for your synthesis essay topic, prioritizing the subjects you feel passionate about.
• Do your research . Once you’ve decided on a topic, use the internet, library, and other sources to perform extensive research. You can turn to academic primary sources to find quotes from scholars and experts, or look up statistics or scientific studies relevant to your topic. This research will help you develop a point of view that is backed up by concrete information. Use credible sources that are unbiased.
• Outline your point . Your entire essay should focus on either explaining a certain perspective or making an argument. Outline how each of your sources relates to your theme and support your idea.
• Write your introduction . An introduction is the first paragraph of a paper. Its main purpose is to present the general premise of the paper, provide any necessary background information, and hopefully, capture the reader’s attention. The introductory paragraph to your synthesis essay should be where you include a strong thesis statement. This is where you will state the point of view that you’re exploring or the argument you’re making.
• Include your body paragraphs . Synthesis essays will typically contain three body paragraphs. A good body paragraph contains three main sections: a topic sentence (or key sentence), relevant supporting  sentences, and a closing (or transition)
• sentence. This structure keeps your paragraph focused on the main idea, providing clear, concise information. Each body paragraph should discuss different elements and supporting arguments of your thesis, along with evidence drawn from each source. Explain the common theme between your resources, as well as how they are relevant to your text. Include counterarguments as well as how your source material can discredit those claims and support your own idea.
• Wrap it up with a strong conclusion . A conclusion is a final piece of writing in a research paper, essay, or article that summarizes the entire work. The concluding paragraph of your synthesis essay will restate your thesis, summarize the key supporting ideas you discussed throughout the work, and offer your final impression of the central idea.
• Proofread . Always proofread your writing a few times before submitting or presenting it. A few missed words or grammatical errors can sometimes change or discredit the entire crux of an argument or opinion. Make sure that your grammar, syntax, and flow are as accurate and clear as possible. This will help you come across as a credible source.

How to write a good AP synthesis essay

Published September 27, 2020. Updated June 7, 2022.

Synthesis Essay Definition

A synthesis essay uses information from multiple sources to support an argument or explanation.

Overview of Synthesis Essay Writing

First, take some time to develop a thorough understanding of what you will be writing about. Take notes as you go, keeping track of points you want to make and evidence you want to include in the essay. While you read, you can begin to brainstorm a thesis statement and outline for the essay. Writing an outline will help structure your essay and keep you on track. The standard synthesis essay outline includes an introduction, body, and conclusion. Spend adequate time reviewing the instructions, sources, and prompts.

The AP English Language and Composition (also known as AP Lang) exam is composed of two sections: a Multiple Choice section and a Free Response section. It’s normal to be nervous before an exam, especially an AP exam. If you’re not sure what to expect from the AP Lang synthesis essay, never fear. Here you can read about everything you need to know before exam day, including:

• the purpose of the synthesis essay
• what to expect from the sources and prompt
• a sample prompt and response
• how the synthesis essay is scored
• how to write a high-scoring synthesis essay

Worried about your writing? Submit your paper for a Chegg Writing essay check , or for an Expert Check proofreading . Both can help you find and fix potential writing issues.

Synthesis essay

The College Board describes the synthesis essay this way:

“After reading 6–7 texts about a topic (including visual and quantitative sources), students will compose an argument that combines and cites at least 3 of the sources to support their thesis.”

You will have 45 minutes to complete the synthesis essay. How you use this time is up to you, but below we’ve included a timeline for how you might choose to use your 45 minutes.

What will the sources and prompt be like?

The six to seven sources will all be centered on a specific topic. In past exams, the prompt has been focused on subjects like alternative energy and eminent domain. At least two of the sources will be visual, and at least one will be numerical (a chart or graph). The others will be text passages of roughly 500 words.

Before the sources, you’ll be given directions and a writing prompt. The prompt will explain the topic, then present a claim for you to respond to. Your response should synthesize material from at least three of the sources, forming a full-fledged essay.

See a sample synthesis essay prompt directly from the College Board linked here.

Following the directions in this sample prompt, you’ll find Sources A-F. Click here to view sample student responses.

How will my synthesis essay be scored?

Synthesis essays will be scored on a range from 0 to 6 based on an analytic rubric. This score will be the total of three scores based on three categories: your thesis, your evidence and commentary, and your sophistication.

Click here to review the complete free-response scoring guidelines for the 2020 AP Lang exam. As a quick summary, we’ll provide the College Board’s descriptions for what warrants the highest and lowest points in each category.

According to the AP English Language Scoring Rubrics, 0 points in the thesis category will be given “for any of the following”:

• There is no defensible thesis.
• The intended thesis only restates the prompt.
• The intended thesis provides a summary of the issue with no apparent or coherent claim.
• There is a thesis, but it does not respond to the prompt.

1 point in the thesis category will be given to essays that respond “to the prompt with a thesis that presents a defensible position.”

0 points will be given in the evidence and commentary section to any essay that “Simply restates thesis (if present), repeats provided information, or references fewer than two of the provided sources.”

4 points will be given in the evidence and commentary section to an essay that “Provides specific evidence from at least three of the provided sources to support all claims in a line of reasoning” and “Consistently explains how the evidence supports a line of reasoning.”

Finally, in the sophistication category , 1 point will be given to an essay that demonstrates “sophistication of thought and/or develops a complex understanding of the rhetorical situation.” 0 points will be given to essays that do not meet that criteria.

While it’s natural to worry about your score, keep in mind that your scorers know you have less than an hour to complete your synthesis essay. They know it is essentially a first draft, and they will pay more mind to what you do right than what you do wrong. Even the highest-scoring essays will contain occasional errors, so worry less about perfection than your holistic argument and synthesis.

How to write a high-scoring synthesis essay

Before we dive into what makes a high-scoring synthesis essay, let’s cover the basics. What is a synthesis essay?

Basically, a synthesis essay uses information from multiple sources to support an argument or explanation. However, when it comes to the AP Lang exam, you will be writing an argumentative synthesis essay.

You’ll take an argumentative stance, which you will express via your thesis statement, and argue in favor of that stance using evidence from multiple sources.

Outstanding AP Lang synthesis essays tend to do the following things very well. They:

• demonstrate an understanding of the topic at hand.
• express understanding of the topic’s importance.
• make the writer’s opinion on the topic clear early on.
• frequently cite examples from the sources, such as statistics and quotes.
• conclude with a strong “so what” point.

To write an essay that succeeds in all of these areas, you should use a few strategies on exam day.

Read, read, and read again

One of the worst mistakes you can make is to jump into outlining and writing before you’ve read and analyzed the directions, prompt, and sources. Though you have limited time, it’s worth taking some time to develop a thorough understanding about what you’ll be writing about.

Take notes as you go, keeping track of points you want to make and evidence you want to include in your essay. While you read, you can begin to brainstorm a thesis statement and outline for your essay.

Follow an outline

Even if you’re more of a “fly by the seat of your pants” type, an outline will help structure your essay and keep you on track.

Below is a standard synthesis essay outline to keep in mind. However, this is only an example, and your argument may not fit this outline exactly.

• Give a bit of context on the subject, demonstrating the knowledge you gained from reviewing the sources.
• Give a clear and concise thesis statement that presents your argument.
• Topic sentence
• Evidence #1
• Evidence #2
• Sum up the main points made in the essay.
• Restate the thesis statement
• End on a “so what?” statement.

Don’t lose track of time

While it’s vital you spend adequate time reviewing the instructions, sources, and prompt, it’s a lost cause if you don’t leave yourself enough time to outline and write!

Here’s a handy timeline to keep in mind during the 55-minute-long synthesis essay portion of the AP Lang exam:

• Reading the directions, sources, and prompt: 15 minutes

AP synthesis example essay

Based on the 2020 prompt : 

The impact of television on political matters has been  under  debate for years. Television provides a low-cost method to  stay informed  about policy changes  and receive  important announcements, and  it  often  offers  a path to learn more about political figures and their plans for the United States. However, critics of television believe that there is a strong psychological and marketing strategy in play,  which  presents  false images of personalities and  is  commonly used as a tool to sway public opinion. While there are drawbacks to  broadcasting debates and politics ,  it  positively influences presidential elections by providing accessible information to viewers ,  shar ing  the candidate s’  personali ties , plans, and ideals during  their  potential role as president,  and  ultimately assisting citizens in casting their vot e.  

The  primary benefit of televising politics is t hat it provides  accessible information . Television, as s ource A explains , provides an opportunity for citizens to be more involved in political matters than ever before, specifically  by adding to  their  knowledge. With public speeches and political events televised, viewers can learn about the structure of the U.S. political system and build a better understanding  of  how legislation is created, in addition to their representative s’  contribution s  to political matters.  The reach of television is clear, as shown in Source D, where millions of viewers tune in every four years for the presidential debates.  T he data reports  that  80.6 million people view ed  the debates in 1980,  and even  in 1996, the chart’s lowest year of ratings, 46.1 million viewers tuned in — all who may have been influenced to vote !  The data shows that television is unmatched in  its  ability to reach voters , proving that it is a beneficial tool for providing information  to help  citizens  make their choices .  

Television also works as a trust-building tool between the viewer and the presidential candidate s . Although the criticism from Source C — which  claim s  that televised debates  are  largely  focused  on image instead of content — is noteworthy,  we  must also consider the relationship development that occurs between the constituent and the politician.  For example, consider  the story of Walter Cronkite, who performed investigat ive  journalism on-site in Vietnam to deliver a message about his opinion of the war. In doing so, he was able to shift the support for the ongoing war into a national call for closure, resulting in the end of the United States ’  presence in Vietnam and potentially saving thousands  of  live s  (Source E) . For presidents, their arguments, vision, and speeches can establish trust with the viewers, raising  citizens’  confidence  in their  ability  to  do the job successfully.  Though  televised appearances do result in investment in public relation campaigns and sometimes  support  an inauthentic view  of their subjects , at the same time, television serves as an important tool to connect citizens with their  president and  candidates .  

Perhaps the most  troubling   element of  televisi ng  presidential elections  is the threat  of commercialism. With the variety of issues and complaints regarding legislation and public policy, presidential candidates may use their live airtime to tackle only the most popular economic and social issues. T ed Koppel  analyzed  this phenomenon  during a past presidential debate,  in which  the television station structured the debate to limit responses from the candidates (Source F) .  This approach is somewhat deceptive, forcing the candidates to come up with quick answers  while  masking other issues.  For example,  only the most popular social issues may have been brought up, sidelining  complex political matters and policy problems  that may have been ongoing for years.  However, while this  format  surely limits candidates ’ ability  to share their opinions on a wide variety of issues, television does allow  the candidates to connect with the masses, which may not be possible through other forms of communication.  I f necessary , the format  of future debates  could be restructured to create  more  space for complex  argumentation   without sacrificing the benefits of televised  communication.  

In summary, t he  influence of television is unprecedented, allowing presidential candidates and other politicians to connect with viewers from across the nation. The critics are justified in  remarking   that  televised debates  may mislead  citizens through their  emphasis on  public image. However,  if audiences  analyz e  the debates, announcements, and other  such  matters with a critical approach,  this highly accessible form of communication  encourages people to build trust with presidential candidates, enhance their worldview, and feel more involved in political matters.

How to Write a Synthesis Essay

Synthesis essays are not as popular as argumentative or analytical essays. Still, you can be assigned to write this type of essay when you study at high school, college, or university. Writing a synthesis essay is also a part of an exam that you have to pass in order to complete the AP English Language and Composition course. As this essay type is uncommon, we will provide you with a detailed and simple guide on how to write a synthesis essay.

What is a synthesis essay?

A synthesis essay is a type of writing that offers a unique viewpoint on a chosen topic backed up with information from multiple sources. It is similar to research papers but has a few limitations.

Firstly, when you write an AP synthesis essay, you don’t have to look for the necessary sources by yourself, as they’re provided in the text of your assignment. The only thing you need to do is pick three or four sources in order to argue the topic. Secondly, you’ll have certain time limitations during the exam. You will have to complete three writing tasks (argument, analysis, and synthesis) in two hours. Finally, topics for synthesis essays are usually broader than ones for research papers.

The AP English Language and Composition exam is not aimed at evaluating students’ knowledge of a specific discipline. Its main purpose is to examine your writing and rhetorical skills, so all topics are debatable and understandable, as they don’t require reading specialized literature.

In general, a synthesis essay has to demonstrate your language competence, not your analytical thinking skills. Still, you should follow a particular logic to make your text readable and to get a higher score.

Main types of synthesis essays

Synthesis essay writing steps

When you compose a synthesis essay, especially for the AP exam, you don’t have much time. Therefore, you need perfect planning. Below, we offer you writing steps divided into three stages for your comfort.

Preparatory work

1. Read instructions thoroughly

Understanding the prompt is crucial for providing a brilliant synthesis essay. Make sure that you take into account all the aspects of the topic.

2. Think about the topic

Sure, you won’t have much time for a full-scale brainstorming session during the exam. Still, you have to look at the suggested theme from different perspectives in order to formulate your unique and interesting viewpoint.

3. Compose a preliminary thesis statement

Write down the first clear idea that will come to your mind after you read the prompt. It doesn’t need to be perfect, as you’ll have a chance to make changes later. The main purpose of this step is to create a base for the further writing process. A good thesis statement is a sentence that answers three questions about your essay at the same time: what, how, and why.

4. Choose sources

When taking an exam, this step is easier than when doing an academic assignment, as all the sources are specified. You have to pick three or four sources of various formats that will enforce your point of view. If you are preparing a synthesis essay for a university, you can use more than four sources, but make sure that you analyze and present properly the ideas of each author.

4. Read the chosen sources thoroughly

Remember that you don’t have much time when you take the exam, so don’t waste it for reading all the provided sources. Only after picking several texts will you begin a detailed reading. You can make short annotations and take notes in order to summarize the main ideas of the chosen sources.

5. Find connections between the sources and your claim

This is the main aspect of any synthesis essay. If you don’t succeed in finding out and explaining to your readers how the chosen sources are related to your thesis, you won’t get a high score for your essay. The sources that you choose shouldn’t necessarily prove your point of view. They can even be contradictory, but links between them have to be clear.

Drafting your essay

To simplify the writing process, we suggest you to use a standard five-paragraph structure: one paragraph for your introduction, three paragraphs for the main body, and one more for your conclusion.

Let’s take a closer look at each part of a synthesis essay.

1. Introduction

An introduction is an extremely important part of your essay, as it has three crucial functions. First of all, you introduce your topic and provide some background information that is necessary for understanding the theme. The next task is to present your sources, as they provide the base for your synthesis essay. Finally, you include your thesis statement in your introduction. Don’t forget that your claim should be relevant to your body paragraphs. As a rule, an introductory section is about 10% of the whole text and consists only of one paragraph.

2. The main body

This part covers about 80% of your synthesis essay. Each paragraph should include a focal point and several quotes that serve as arguments. You should follow the rule of one paragraph, one idea. However, don’t omit the logical connections between parts of the main body and different sources. Your main purpose is to show how you can synthesize multiple sources in order to prove your personal point of view.

3. Conclusion

When you write the concluding part of your essay, the main thing is to show confidence. A confident tone will persuade your readers that your viewpoint is correct and your argumentation is immaculate. Restate your thesis statement and summarize connections between your initial claim and cited sources. Be concise and avoid long phrases: your conclusion should be only 10% of the whole text.

Final touches

1. Reread your essay

It is hard to do everything perfectly on the first try. In order to notice all the mistakes and inaccuracies, reread your writing thoroughly.

2. Write a final thesis statement

Make sure that your thesis statement is relevant to the main body. If not, rewrite it to create a smooth connection between your claim and argumentation.

3. Edit your text

If you’re sure that everything is fine with the content of your synthesis essay, it’s time to get rid of grammatical mistakes, poor wording, spelling mistakes, and incorrect punctuation. Remember that even the most eloquent text will look like the work of an amateur if there are dozens of mistakes.

AP lang synthesis essay

On the AP Language and Composition exam, you will need to write a synthesis essay as part of the free-response section. For this essay, you will be provided with prompts and several sources to support your argument. To prepare for this essay, it is important to read through each source carefully, take notes, and create an outline before starting to write. Remember to include at least three sources in your essay and to cite them properly. Here are some important facts to keep in mind about the AP Lang Synthesis Essay:

• Purpose . The synthesis essay is a type of exam paper that students write to show their analytical skills and ability to work with sources and write essays based on them.
• Time limit . The work time is 55 minutes.
• Organization . Composition of the synthesis essay is the following:
• Introduction with a thesis statement.
• Argument from the source No. 1.
• Argument from the source No. 2.
• Argument from the source No. 3.
• Conclusion.
• Compliance with the topic . You should stay on topic and support the chosen quote or question.
• Argumentation using several sources . The point of a synthesis essay is to confirm your statements, using as examples the sources you have given.
• Composition and logic of reasoning . The criterion implies adherence to semantic division into paragraphs, logical sequence of presentation of thoughts, as well as constructive proof of one’s opinion.
• Quality of writing style . In the synthesis essay, use diverse speech structures, but ones that are correct  grammatically, syntactically and lexically.

Synthesis essay topics

How to choose an exciting topic for a synthesis essay.

A synthesis essay is an opportunity to share your opinion on two or more texts. You will need to analyze a particular issue and support your point of view with evidence. This type of essay is common in high school and college English courses.

When choosing a topic for your synthesis essay, you need to find a way to connect the sources. Connecting different sources to support your point to make a perfect essay can be done by finding a common theme or providing a critical analysis of each source. If you are still looking for a connection, try looking for a common thread that ties the sources together.

Once you have found a connection, you must decide what direction you want your essay to take.

• Do you agree with the sources?
• Do you disagree?
• Do you see a different perspective?

Your position will be the basis for your synthesis essay.

Why do you need to explore expert samples

As you know, a synthesis essay is about drawing information from various sources and piecing it together to create a cohesive whole. The process can be tricky and one that can be made much easier with the help of expert samples.

1. It can be difficult to identify all the necessary elements independently

When looking at a blank page, it can be challenging to know where to start. It, therefore, becomes more challenging when tasked with writing a synthesis essay since you need to include so many elements that can be difficult to identify without the help of an expert. Thus, this is where expert samples come in handy. By reading through a few examples, you can better understand what’s required and what’s optional.

2. You’ll be able to see how different writers approach the same topic

One of the great things about exploring expert samples is that you’ll be able to see how other writers approach the same issue. Subsequently, this can give you valuable insights into how you might want to approach your essay.

3. You can learn from the mistakes of others

While reading through expert samples, you’ll inevitably come across some that are better than others. Consequently, this is an excellent opportunity to learn from the mistakes of others and make sure that you don’t make the same mistakes in your essay.

4. You’ll get a better sense of what the professor expects

If you need clarification on what your teacher or professor is looking for, expert samples can be a great way to give a better experience of what the professor expects. Reading through a few expert examples gives you a clearer idea of the professors’ expectations, and you can formulate your thoughts.

5. You can find inspiration for your essay

Finally, one of the best reasons to explore expert samples is that they can provide much-needed inspiration. If you’re stuck, a few well-written examples can jumpstart your creative process and help you develop great ideas for your essay.

5 helpful tips to write a synthesis essay

1. Acceptable number of sources

If you need to take the AP exam, you have to use at least three sources (you can use a maximum of four sources). If you must write a synthesis essay as an academic assignment, you may use more sources. However, we don’t recommend you to exceed the limit of six sources, as it can be very hard to present a greater number of works in a proper way. You can cite the same source several times, and it will still be considered as one source.

2. Proper citation

When you include a quote in your essay, introduce, punctuate, and cite it properly. Mention the author’s name and use quotation marks if necessary. In parentheses, write the title of your source.

3. Counter-argument

Addressing a counter-argument is a helpful argumentation strategy. In such a way, you demonstrate that your point of view on this particular topic is not unique. However, you can show that the counter-argument is weak, and this will convince your readers that your claim is more valid.

4. Language skills

This tip is mostly accurate for the AP exam. The free-response writing section, which includes a synthesis essay, is aimed at evaluating your language performance. Don’t hesitate to use fancy wording, terms, complex grammar structures, linking words, and figures of speech that will demonstrate your language skills.

5. Importance of the form

The main purpose of the synthesis essay is to show how you can use multiple sources and create connections between them and demonstrate your writing skills. Your top priority is not offering a unique point of view that will amaze your readers. Of course, a bit of novelty won’t hurt. Still, your primary task is to be eloquent and logical, not creative.

We hope that you’ve learned more about a synthesis essay thanks to our guide. Practice your writing regularly in order to achieve great results and get higher scores!

Synthesis essay.

The synthesis essay asks that you read a number of sources and comment on them in an original way. The best way to approach this complicated assignment is to plan. 

Comparing the Sources: Use the chart below to record the information asked in the left column.

Finding Dissonance: Your next step is to isolate feelings of curiosity, wonder, puzzlement, irritation, frustration—any kind of surprise or discomfort that you feel after reading all these sources.  Let’s consider some of the major ways that readers might feel this way.  Remember that dissonance (a musical term meaning a lack of harmony) doesn’t always mean negative things—it can be very positive—imagine finding a solution to a huge problem like treating teen depression.

Dissonance Table:

Articulating a Question: Once you’ve isolated the kinds of dissonance that you might have, then shape that into a question that you don’t know the answer to. 

After you’ve read all sources and isolated dissonances, you want to know

Any More Research Needed? In order to answer that question, you might have to do more research.  If you are new to a particular subject area, you might need to consult with a research librarian.

Answer That Question: Once you have finished with your research (if needed), go back to that question and answer it.  That becomes the THESIS or FOCUS for your paper.  Try it here.

Imagining Your Reader: A key to successful writing is to imagine your reader in the following ways:             *  see the person as open minded             *  understand that your professor wants you to learn             *  believe that the professor him- or herself wants to learn from you             *  take some joy in presenting information in terms of your focus

Structuring the Paper: Use your focus to guide every paragraph.  Imagine that your readers want to know how you see the variety of sources on a particular topic—what they want is YOUR INDIVIDUAL UNDERSTANDING of this matter, which is what you just wrote about in your planning.  Keep to that as you write your essay and NOT to a recounting of the information in the articles.  Just reporting what exists is doing high school work, not college work. 

Have Someone Read Your Paper Before You Submit It! This kind of paper is an advanced paper—so be sure to have someone read over it for grammatical mistakes or better style.

In a synthesis, you bring things together. This combination, integration, or merging creates something new--your synthesis. The action of synthesis is basic to our world. Take, for example, what happens when a single oxygen molecule is combined with two hydrogen molecules. Water is created or synthesized. Hard to get more basic than that.

You also use synthesis to make personal decisions. If two instructors are teaching a class you must take, you may synthesize your past experiences with the teachers to choose the best class for you.

Research Essays:

Thesis driven.

In school, when writing a synthesis from your research, your sources may come from the school's library, a textbook, or the Internet. Here are some important points to keep in mind:

First, regardless of where your sources come from or how many you have, what you write should be driven by a thesis that you devise. After reading and studying your sources, you should form a personal point of view, a slant to connect your sources.

Here's a quick example--Let's say you've read three folktales: Goldilocks and the Three Bears, Little Red Riding Hood, and the Pied Piper--and now you must write a synthesis of them. As you study the three sources, you think about links between them and come up with this thesis: 

Folktales use fear to teach children lessons.

Then you use this thesis to synthesize your three sources as you support your point of view. You combine elements from the three sources to prove and illustrate this thesis. Your support points could focus on the lessons for children:

• Lesson 1 : Never talk to strangers.
• Lesson 2 : Don't wander from home.
• Lesson 3 : Appearances can deceive us.

This step of outlining your thesis and main points is a crucial one when writing a synthesis. If your goal in writing a research essay is to provide readers a unified perspective based on sources, the unified perspective must be clear before the writing begins.

Once the writing begins, your point of view is then carried through to the paragraph and sentence levels. Let's examine some techniques for achieving the unity that a good synthesis requires. First, here’s an example of an unsuccessful attempt at synthesizing sources:

Many sources agree that capital punishment is not a crime deterrent. [This is the idea around which the sources should be unified. Now comes the sources] According to Judy Pennington in an interview with Helen Prejean, crime rates in New Orleans rise for at least eight weeks following executions (110). Jimmy Dunne notes that crime rates often go up in the first two or three months following an execution. “Death in the Americas” argues that America’s crime rate as a whole has increased drastically since the re-instatement of the death penalty in the 1960s. The article notes that 700 crimes are committed for every 100,000 Americans (2). Helen Prejean cites Ellis in her book to note that in 1980, 500,000 people were behind bars and in 1990 that figure rose to 1.1 million (112).

Sample student paragraph adapted from "Literature Review: Synthesizing Multiple Sources." Retrieved 2011 from https://scholarworks.iupui.edu/items/7dda80e7-b0b3-477c-a972-283b48cfdf5c

This paragraph certainly uses a number of sources. However, the sources are presented in a random, grocery list fashion. Besides the main point at the beginning, there is no further attempt to synthesize. The sources seem tossed in, like ingredients in a salad. Let's examine a possible revision of that paragraph and how an adequate synthesis might be achieved:

Major studies suggest that capital punishment fails to deter crime. Helen Prejean, in "Deadman Walking," reviews decades of statistics that indicate capital punishment does little to lower crime. [Key idea from  topic sentence—"capital punishment fails to deter crime"— echoed in sentence about source–"capital punishment does little to lower crime." Repetition links source to main idea.] Based on this evidence, Prejean concludes “Executions do not deter crime . . . the U.S. murder rate is no higher in states that do not have the death penalty than those who do” (110). ["Based on this evidence" forces  reader to refer back to "statistics" in previous sentence.] Prejean’s point is reiterated from a historical perspective in Dunne's article “Death in the Americas.”  [This sentence provides a thought bridge between two sources.] Dunne first points out that, despite the social and economic upheavals from 1930 to 1960, crime rates were unchanged (2). [Linking phrase:"Dunne first points out"] However, after the reinstatement of the death penalty in the 1960s, “crime rates soared” (2). [Linking phase "However, Dunne notes."]

The result is a matrix of connective devices that unifies the sources around a key idea stated at the beginning. Although this matrix seems complex, it is actually built on a simple three-point strategy.

• Stay in charge . You the writer must control the sources, using them to serve your purpose. In good synthesis writing, sources are used to support what you, the writer, have already said in your own words.
• Stay focused . Your main point is not merely stated once and left to wilt. Your main idea is repeated and echoed throughout as a way to link the sources, to weave them together into a strong fabric of meaning.
• Stay strategic . Notice the "source sandwich" strategy at work. First, the author sets up the source with its background and relevance to the point. After the source comes a follows up in his/her own words as a way to bridge or link to the next part. In other words, the writer's own words are used like two slices of bread, with the source in the middle.

Follow these simple principles when using sources in your writing and you will achieve the most important goal of synthesis writing--to create a whole greater than its parts.

How to Write a Perfect Synthesis Essay for the AP Language Exam

Advanced Placement (AP)

If you're planning to take the AP Language (or AP Lang) exam , you might already know that 55% of your overall exam score will be based on three essays. The first of the three essays you'll have to write on the AP Language exam is called the "synthesis essay." If you want to earn full points on this portion of the AP Lang Exam, you need to know what a synthesis essay is and what skills are assessed by the AP Lang synthesis essay.

In this article, we'll explain the different aspects of the AP Lang synthesis essay, including what skills you need to demonstrate in your synthesis essay response in order to achieve a good score. We'll also give you a full breakdown of a real AP Lang Synthesis Essay prompt, provide an analysis of an AP Lang synthesis essay example, and give you four tips for how to write a synthesis essay.

Let's get started by taking a closer look at how the AP Lang synthesis essay works!

Synthesis Essay AP Lang: What It Is and How It Works

The AP Lang synthesis essay is the first of three essays included in the Free Response section of the AP Lang exam.

The AP Lang synthesis essay portion of the Free Response section lasts for one hour total . This hour consists of a recommended 15 minute reading period and a 40 minute writing period. Keep in mind that these time allotments are merely recommendations, and that exam takers can parse out the allotted 60 minutes to complete the synthesis essay however they choose.

Now, here's what the structure of the AP Lang synthesis essay looks like. The exam presents six to seven sources that are organized around a specific topic (like alternative energy or eminent domain, which are both past synthesis exam topics).

Of these six to seven sources, at least two are visual , including at least one quantitative source (like a graph or pie chart, for example). The remaining four to five sources are print text-based, and each one contains approximately 500 words.

In addition to six to seven sources, the AP Lang exam provides a written prompt that consists of three paragraphs. The prompt will briefly explain the essay topic, then present a claim that students will respond to in an essay that synthesizes material from at least three of the sources provided.

Here's an example prompt provided by the College Board:

Directions : The following prompt is based on the accompanying six sources.

This question requires you to integrate a variety of sources into a coherent, well-written essay. Refer to the sources to support your position; avoid mere paraphrase or summary. Your argument should be central; the sources should support this argument .

Remember to attribute both direct and indirect citations.

Introduction

Television has been influential in United States presidential elections since the 1960's. But just what is this influence, and how has it affected who is elected? Has it made elections fairer and more accessible, or has it moved candidates from pursuing issues to pursuing image?

Read the following sources (including any introductory information) carefully. Then, in an essay that synthesizes at least three of the sources for support, take a position that defends, challenges, or qualifies the claim that television has had a positive impact on presidential elections.

Refer to the sources as Source A, Source B, etc.; titles are included for your convenience.

Source A (Campbell) Source B (Hart and Triece) Source C (Menand) Source D (Chart) Source E (Ranney) Source F (Koppel)

Like we mentioned earlier, this prompt gives you a topic — which it briefly explains — then asks you to take a position. In this case, you'll have to choose a stance on whether television has positively or negatively affected U.S. elections. You're also given six sources to evaluate and use in your response. Now that you have everything you need, now your job is to write an amazing synthesis essay.

But what does "synthesize" mean, exactly? According to the CollegeBoard, when an essay prompt asks you to synthesize, it means that you should "combine different perspectives from sources to form a support of a coherent position" in writing. In other words, a synthesis essay asks you to state your claim on a topic, then highlight the relationships between several sources that support your claim on that topic. Additionally, you'll need to cite specific evidence from your sources to prove your point.

The synthesis essay counts for six of the total points on the AP Lang exam . Students can receive 0-1 points for writing a thesis statement in the essay, 0-4 based on incorporation of evidence and commentary, and 0-1 points based on sophistication of thought and demonstrated complex understanding of the topic.

You'll be evaluated based on how effectively you do the following in your AP Lang synthesis essay:

Write a thesis that responds to the exam prompt with a defensible position

Provide specific evidence that to support all claims in your line of reasoning from at least three of the sources provided, and clearly and consistently explain how the evidence you include supports your line of reasoning

Demonstrate sophistication of thought by either crafting a thoughtful argument, situating the argument in a broader context, explaining the limitations of an argument

Make rhetorical choices that strengthen your argument and/or employ a vivid and persuasive style throughout your essay.

If your synthesis essay meets the criteria above, then there's a good chance you'll score well on this portion of the AP Lang exam!

If you're looking for even more information on scoring, the College Board has posted the AP Lang Free Response grading rubric on its website. ( You can find it here. ) We recommend taking a close look at it since it includes additional details about the synthesis essay scoring.

Don't be intimidated...we're going to teach you how to break down even the hardest AP synthesis essay prompt.

Full Breakdown of a Real AP Lang Synthesis Essay Prompt

In this section, we'll teach you how to analyze and respond to a synthesis essay prompt in five easy steps, including suggested time frames for each step of the process.

Step 1: Analyze the Prompt

The very first thing to do when the clock starts running is read and analyze the prompt. To demonstrate how to do this, we'll look at the sample AP Lang synthesis essay prompt below. This prompt comes straight from the 2018 AP Lang exam:

Eminent domain is the power governments have to acquire property from private owners for public use. The rationale behind eminent domain is that governments have greater legal authority over lands within their dominion than do private owners. Eminent domain has been instituted in one way or another throughout the world for hundreds of years.

Carefully read the following six sources, including the introductory information for each source. Then synthesize material from at least three of the sources and incorporate it into a coherent, well-developed essay that defends, challenges, or qualifies the notion that eminent domain is productive and beneficial.

Your argument should be the focus of your essay. Use the sources to develop your argument and explain the reasoning for it. Avoid merely summarizing the sources. Indicate clearly which sources you are drawing from, whether through direct quotation, paraphrase, or summary. You may cite the sources as Source A, Source B, etc., or by using the descriptions in parentheses.

On first read, you might be nervous about how to answer this prompt...especially if you don't know what eminent domain is! But if you break the prompt down into chunks, you'll be able to figure out what the prompt is asking you to do in no time flat.

To get a full understanding of what this prompt wants you to do, you need to identify the most important details in this prompt, paragraph by paragraph. Here's what each paragraph is asking you to do:

• Paragraph 1: The prompt presents and briefly explains the topic that you'll be writing your synthesis essay about. That topic is the concept of eminent domain.
• Paragraph 2: The prompt presents a specific claim about the concept of eminent domain in this paragraph: Eminent domain is productive and beneficial. This paragraph instructs you to decide whether you want to defend, challenge, or qualify that claim in your synthesis essay , and use material from at least three of the sources provided in order to do so.
• Paragraph 3: In the last paragraph of the prompt, the exam gives you clear instructions about how to approach writing your synthesis essay . First, make your argument the focus of the essay. Second, use material from at least three of the sources to develop and explain your argument. Third, provide commentary on the material you include, and provide proper citations when you incorporate quotations, paraphrases, or summaries from the sources provided.

So basically, you'll have to agree with, disagree with, or qualify the claim stated in the prompt, then use at least three sources substantiate your answer. Since you probably don't know much about eminent domain, you'll probably decide on your position after you read the provided sources.

To make good use of your time on the exam, you should spend around 2 minutes reading the prompt and making note of what it's asking you to do. That will leave you plenty of time to read the sources provided, which is the next step to writing a synthesis essay.

Step 2: Read the Sources Carefully

After you closely read the prompt and make note of the most important details, you need to read all of the sources provided. It's tempting to skip one or two sources to save time--but we recommend you don't do this. That's because you'll need a thorough understanding of the topic before you can accurately address the prompt!

For the sample exam prompt included above, there are six sources provided. We're not going to include all of the sources in this article, but you can view the six sources from this question on the 2018 AP Lang exam here . The sources include five print-text sources and one visual source, which is a cartoon.

As you read the sources, it's important to read quickly and carefully. Don't rush! Keep your pencil in hand to quickly mark important passages that you might want to use as evidence in your synthesis. While you're reading the sources and marking passages, you want to think about how the information you're reading influences your stance on the issue (in this case, eminent domain).

When you finish reading, take a few seconds to summarize, in a phrase or sentence, whether the source defends, challenges, or qualifies whether eminent domain is beneficial (which is the claim in the prompt) . Though it might not feel like you have time for this, it's important to give yourself these notes about each source so you know how you can use each one as evidence in your essay.

Here's what we mean: say you want to challenge the idea that eminent domain is useful. If you've jotted down notes about each source and what it's saying, it will be easier for you to pull the relevant information into your outline and your essay.

So how much time should you spend reading the provided sources? The AP Lang exam recommends taking 15 minutes to read the sources . If you spend around two of those minutes reading and breaking down the essay prompt, it makes sense to spend the remaining 13 minutes reading and annotating the sources.

If you finish reading and annotating early, you can always move on to drafting your synthesis essay. But make sure you're taking your time and reading carefully! It's better to use a little extra time reading and understanding the sources now so that you don't have to go back and re-read the sources later.

A strong thesis will do a lot of heavy lifting in your essay. (See what we did there?)

Step 3: Write a Strong Thesis Statement

After you've analyzed the prompt and thoroughly read the sources, the next thing you need to do in order to write a good synthesis essay is write a strong thesis statement .

The great news about writing a thesis statement for this synthesis essay is that you have all the tools you need to do it at your fingertips. All you have to do in order to write your thesis statement is decide what your stance is in relationship to the topic provided.

In the example prompt provided earlier, you're essentially given three choices for how to frame your thesis statement: you can either defend, challenge, or qualify a claim that's been provided by the prompt, that eminent domain is productive and beneficial . Here's what that means for each option:

If you choose to defend the claim, your job will be to prove that the claim is correct . In this case, you'll have to show that eminent domain is a good thing.

If you choose to challenge the claim, you'll argue that the claim is incorrect. In other words, you'll argue that eminent domain isn't productive or beneficial.

If you choose to qualify, that means you'll agree with part of the claim, but disagree with another part of the claim. For instance, you may argue that eminent domain can be a productive tool for governments, but it's not beneficial for property owners. Or maybe you argue that eminent domain is useful in certain circumstances, but not in others.

When you decide whether you want your synthesis essay to defend, challenge, or qualify that claim, you need to convey that stance clearly in your thesis statement. You want to avoid simply restating the claim provided in the prompt, summarizing the issue without making a coherent claim, or writing a thesis that doesn't respond to the prompt.

Here's an example of a thesis statement that received full points on the eminent domain synthesis essay:

Although eminent domain can be misused to benefit private interests at the expense of citizens, it is a vital tool of any government that intends to have any influence on the land it governs beyond that of written law.

This thesis statement received full points because it states a defensible position and establishes a line of reasoning on the issue of eminent domain. It states the author's position (that some parts of eminent domain are good, but others are bad), then goes on to explain why the author thinks that (it's good because it allows the government to do its job, but it's bad because the government can misuse its power.)

Because this example thesis statement states a defensible position and establishes a line of reasoning, it can be elaborated upon in the body of the essay through sub-claims, supporting evidence, and commentary. And a solid argument is key to getting a six on your synthesis essay for AP Lang!

Step 4: Create a Bare-Bones Essay Outline

Once you've got your thesis statement drafted, you have the foundation you need to develop a bare bones outline for your synthesis essay. Developing an outline might seem like it's a waste of your precious time, but if you develop your outline well, it will actually save you time when you start writing your essay.

With that in mind, we recommend spending 5 to 10 minutes outlining your synthesis essay . If you use a bare-bones outline like the one below, labeling each piece of content that you need to include in your essay draft, you should be able to develop out the most important pieces of the synthesis before you even draft the actual essay.

To help you see how this can work on test day, we've created a sample outline for you. You can even memorize this outline to help you out on test day! In the outline below, you'll find places to fill in a thesis statement, body paragraph topic sentences, evidence from the sources provided, and commentary :

• Present the context surrounding the essay topic in a couple of sentences (this is a good place to use what you learned about the major opinions or controversies about the topic from reading your sources).
• Write a straightforward, clear, and concise thesis statement that presents your stance on the topic
• Topic sentence presenting first supporting point or claim
• Evidence #1
• Commentary on Evidence #1
• Evidence #2 (if needed)
• Commentary on Evidence #2 (if needed)
• Topic sentence presenting second supporting point or claim
• Topic sentence presenting three supporting point or claim
• Sums up the main line of reasoning that you developed and defended throughout the essay
• Reiterates the thesis statement

Taking the time to develop these crucial pieces of the synthesis in a bare-bones outline will give you a map for your final essay. Once you have a map, writing the essay will be much easier.

Step 5: Draft Your Essay Response

The great thing about taking a few minutes to develop an outline is that you can develop it out into your essay draft. After you take about 5 to 10 minutes to outline your synthesis essay, you can use the remaining 30 to 35 minutes to draft your essay and review it.

Since you'll outline your essay before you start drafting, writing the essay should be pretty straightforward. You'll already know how many paragraphs you're going to write, what the topic of each paragraph will be, and what quotations, paraphrases, or summaries you're going to include in each paragraph from the sources provided. You'll just have to fill in one of the most important parts of your synthesis—your commentary.

Commentaries are your explanation of why your evidence supports the argument you've outlined in your thesis. Your commentary is where you actually make your argument, which is why it's such a critical part of your synthesis essay.

When thinking about what to say in your commentary, remember one thing the AP Lang synthesis essay prompt specifies: don't just summarize the sources. Instead, as you provide commentary on the evidence you incorporate, you need to explain how that evidence supports or undermines your thesis statement . You should include commentary that offers a thoughtful or novel perspective on the evidence from your sources to develop your argument.

One very important thing to remember as you draft out your essay is to cite your sources. The AP Lang exam synthesis essay prompt indicates that you can use generic labels for the sources provided (e.g. "Source 1," "Source 2," "Source 3," etc.). The exam prompt will indicate which label corresponds with which source, so you'll need to make sure you pay attention and cite sources accurately. You can cite your sources in the sentence where you introduce a quote, summary, or paraphrase, or you can use a parenthetical citation. Citing your sources affects your score on the synthesis essay, so remembering to do this is important.

Real-Life AP Synthesis Essay Example and Analysis

If you're still wondering how to write a synthesis essay, examples of real essays from past AP Lang exams can make things clearer. These real-life student AP synthesis essay responses can be great for helping you understand how to write a synthesis essay that will knock the graders' socks off .

While there are multiple essay examples online, we've chosen one to take a closer look at. We're going to give you a brief analysis of one of these example student synthesis essays from the 2019 AP Lang Exam below!

Example Synthesis Essay AP Lang Response

To get started, let's look at the official prompt for the 2019 synthesis essay:

In response to our society's increasing demand for energy, large-scale wind power has drawn attention from governments and consumers as a potential alternative to traditional materials that fuel our power grids, such as coal, oil, natural gas, water, or even newer sources such as nuclear or solar power. Yet the establishment of large-scale, commercial-grade wind farms is often the subject of controversy for a variety of reasons.

Carefully read the six sources, found on the AP English Language and Composition 2019 Exam (Question 1), including the introductory information for each source. Write an essay that synthesizes material from at least three of the sources and develops your position on the most important factors that an individual or agency should consider when deciding whether to establish a wind farm.

Source A (photo) Source B (Layton) Source C (Seltenrich) Source D (Brown) Source E (Rule) Source F (Molla)

In your response you should do the following:

• Respond to the prompt with a thesis presents a defensible position.
• Select and use evidence from at least 3 of the provided sources to support your line of reasoning. Indicate clearly the sources used through direct quotation, paraphrase, or summary. Sources may be cited as Source A, Source B, etc., or by using the description in parentheses.
• Explain how the evidence supports your line of reasoning.
• Use appropriate grammar and punctuation in communicating your argument.

Now that you know exactly what the prompt asked students to do on the 2019 AP Lang synthesis essay, here's an AP Lang synthesis essay example, written by a real student on the AP Lang exam in 2019:

[1] The situation has been known for years, and still very little is being done: alternative power is the only way to reliably power the changing world. The draw of power coming from industry and private life is overwhelming current sources of non-renewable power, and with dwindling supplies of fossil fuels, it is merely a matter of time before coal and gas fuel plants are no longer in operation. So one viable alternative is wind power. But as with all things, there are pros and cons. The main factors for power companies to consider when building wind farms are environmental boon, aesthetic, and economic factors.

[2] The environmental benefits of using wind power are well-known and proven. Wind power is, as qualified by Source B, undeniably clean and renewable. From their production requiring very little in the way of dangerous materials to their lack of fuel, besides that which occurs naturally, wind power is by far one of the least environmentally impactful sources of power available. In addition, wind power by way of gearbox and advanced blade materials, has the highest percentage of energy retention. According to Source F, wind power retains 1,164% of the energy put into the system – meaning that it increases the energy converted from fuel (wind) to electricity 10 times! No other method of electricity production is even half that efficient. The efficiency and clean nature of wind power are important to consider, especially because they contribute back to power companies economically.

[3] Economically, wind power is both a boon and a bone to electric companies and other users. For consumers, wind power is very cheap, leading to lower bills than from any other source. Consumers also get an indirect reimbursement by way of taxes (Source D). In one Texan town, McCamey, tax revenue increased 30% from a wind farm being erected in the town. This helps to finance improvements to the town. But, there is no doubt that wind power is also hurting the power companies. Although, as renewable power goes, wind is incredibly cheap, it is still significantly more expensive than fossil fuels. So, while it is helping to cut down on emissions, it costs electric companies more than traditional fossil fuel plants. While the general economic trend is positive, there are some setbacks which must be overcome before wind power can take over as truly more effective than fossil fuels.

[4] Aesthetics may be the greatest setback for power companies. Although there may be significant economic and environmental benefit to wind power, people will always fight to preserve pure, unspoiled land. Unfortunately, not much can be done to improve the visual aesthetics of the turbines. White paint is the most common choice because it "[is] associated with cleanliness." (Source E). But, this can make it stand out like a sore thumb, and make the gargantuan machines seem more out of place. The site can also not be altered because it affects generating capacity. Sound is almost worse of a concern because it interrupts personal productivity by interrupting people's sleep patterns. One thing for power companies to consider is working with turbine manufacturing to make the machines less aesthetically impactful, so as to garner greater public support.

[5] As with most things, wind power has no easy answer. It is the responsibility of the companies building them to weigh the benefits and the consequences. But, by balancing economics, efficiency, and aesthetics, power companies can create a solution which balances human impact with environmental preservation.

And that's an entire AP Lang synthesis essay example, written in response to a real AP Lang exam prompt! It's important to remember AP Lang exam synthesis essay prompts are always similarly structured and worded, and students often respond in around the same number of paragraphs as what you see in the example essay response above.

Next, let's analyze this example essay and talk about what it does effectively, where it could be improved upon, and what score past exam scorers awarded it.

To get started on an analysis of the sample synthesis essay, let's look at the scoring commentary provided by the College Board:

• For development of thesis, the essay received 1 out of 1 possible points
• For evidence and commentary, the essay received 4 out of 4 possible points
• For sophistication of thought, the essay received 0 out of 1 possible points.

This means that the final score for this example essay was a 5 out of 6 possible points . Let's look more closely at the content of the example essay to figure out why it received this score breakdown.

Thesis Development

The thesis statement is one of the three main categories that is taken into consideration when you're awarded points on this portion of the exam. This sample essay received 1 out of 1 total points.

Now, here's why: the thesis statement clearly and concisely conveys a position on the topic presented in the prompt--alternative energy and wind power--and defines the most important factors that power companies should consider when deciding whether to establish a wind farm.

Evidence and Commentary

The second key category taken into consideration when synthesis exams are evaluated is incorporation of evidence and commentary. This sample received 4 out of 4 possible points for this portion of the synthesis essay. At bare minimum, this sample essay meets the requirement mentioned in the prompt that the writer incorporate evidence from at least three of the sources provided.

On top of that, the writer does a good job of connecting the incorporated evidence back to the claim made in the thesis statement through effective commentary. The commentary in this sample essay is effective because it goes beyond just summarizing what the provided sources say. Instead, it explains and analyzes the evidence presented in the selected sources and connects them back to supporting points the writer makes in each body paragraph.

Finally, the writer of the essay also received points for evidence and commentary because the writer developed and supported a consistent line of reasoning throughout the essay . This line of reasoning is summed up in the fourth paragraph in the following sentence: "One thing for power companies to consider is working with turbine manufacturing to make the machines less aesthetically impactful, so as to garner greater public support."

Because the writer did a good job consistently developing their argument and incorporating evidence, they received full marks in this category. So far, so good!

Sophistication of Thought

Now, we know that this essay received a score of 5 out of 6 total points, and the place where the writer lost a point was on the basis of sophistication of thought, for which the writer received 0 out of 1 points. That's because this sample essay makes several generalizations and vague claims where it could have instead made specific claims that support a more balanced argument.

For example, in the following sentence from the 5th paragraph of the sample essay, the writer misses the opportunity to state specific possibilities that power companies should consider for wind energy . Instead, the writer is ambiguous and non-committal, saying, "As with most things, wind power has no easy answer. It is the responsibility of the companies building them to weigh the benefits and consequences."

If the writer of this essay was interested in trying to get that 6th point on the synthesis essay response, they could consider making more specific claims. For instance, they could state the specific benefits and consequences power companies should consider when deciding whether to establish a wind farm. These could include things like environmental impacts, economic impacts, or even population density!

Despite losing one point in the last category, this example synthesis essay is a strong one. It's well-developed, thoughtfully written, and advances an argument on the exam topic using evidence and support throughout.

4 Tips for How to Write a Synthesis Essay

AP Lang is a timed exam, so you have to pick and choose what you want to focus on in the limited time you're given to write the synthesis essay. Keep reading to get our expert advice on what you should focus on during your exam.

Tip 1: Read the Prompt First

It may sound obvious, but when you're pressed for time, it's easy to get flustered. Just remember: when it comes time to write the synthesis essay, read the prompt first !

Why is it so important to read the prompt before you read the sources? Because when you're aware of what kind of question you're trying to answer, you'll be able to read the sources more strategically. The prompt will help give you a sense of what claims, points, facts, or opinions to be looking for as you read the sources.

Reading the sources without having read the prompt first is kind of like trying to drive while wearing a blindfold: you can probably do it, but it's likely not going to end well!

Tip 2: Make Notes While You Read

During the 15-minute reading period at the beginning of the synthesis essay, you'll be reading through the sources as quickly as you can. After all, you're probably anxious to start writing!

While it's definitely important to make good use of your time, it's also important to read closely enough that you understand your sources. Careful reading will allow you to identify parts of the sources that will help you support your thesis statement in your essay, too.

As you read the sources, consider marking helpful passages with a star or check mark in the margins of the exam so you know which parts of the text to quickly re-read as you form your synthesis essay. You might also consider summing up the key points or position of each source in a sentence or a few words when you finish reading each source during the reading period. Doing so will help you know where each source stands on the topic given and help you pick the three (or more!) that will bolster your synthesis argument.

Tip 3: Start With the Thesis Statement

If you don't start your synthesis essay with a strong thesis statement, it's going to be tough to write an effective synthesis essay. As soon as you finish reading and annotating the provided sources, the thing you want to do next is write a strong thesis statement.

According to the CollegeBoard grading guidelines for the AP Lang synthesis essay, a strong thesis statement will respond to the prompt— not restate or rephrase the prompt. A good thesis will take a clear, defensible position on the topic presented in the prompt and the sources.

In other words, to write a solid thesis statement to guide the rest of your synthesis essay, you need to think about your position on the topic at hand and then make a claim about the topic based on your position. This position will either be defending, challenging, or qualifying the claim made in the essay's prompt.

The defensible position that you establish in your thesis statement will guide your argument in the rest of the essay, so it's important to do this first. Once you have a strong thesis statement, you can begin outlining your essay.

Tip 4: Focus on Your Commentary

Writing thoughtful, original commentary that explains your argument and your sources is important. In fact, doing this well will earn you four points (out of a total of six)!

AP Lang provides six to seven sources for you on the exam, and you'll be expected to incorporate quotations, paraphrases, or summaries from at least three of those sources into your synthesis essay and interpret that evidence for the reader.

While incorporating evidence is very important, in order to get the extra point for "sophistication of thought" on the synthesis essay, it's important to spend more time thinking about your commentary on the evidence you choose to incorporate. The commentary is your chance to show original thinking, strong rhetorical skills, and clearly explain how the evidence you've included supports the stance you laid out in your thesis statement.

To earn the 6th possible point on the synthesis essay, make sure your commentary demonstrates a nuanced understanding of the source material, explains this nuanced understanding, and places the evidence incorporated from the sources in conversation with each other. To do this, make sure you're avoiding vague language. Be specific when you can, and always tie your commentary back to your thesis!

Essay Papers Writing Online

10 effective strategies for writing a successful synthesis essay that will impress your readers.

In the realm of written expression, the fusion of ideas from various sources has long been regarded as one of the most intellectually stimulating endeavors. Being able to synthesize information from disparate fields of knowledge not only demonstrates a profound understanding of the subject matter, but also enables the author to introduce novel insights and perspectives. A synthesis essay, as its name suggests, requires a writer to assimilate and integrate ideas, arguments, and evidence from multiple sources into a cohesive and compelling piece of writing. This type of essay invites writers to harness their analytical skills and creative thinking abilities to produce a work that advances a unique and persuasive viewpoint.

Central to the craft of writing a synthesis essay is the utilization of synthesis techniques, which allow the author to achieve the desired integration of ideas. By employing these techniques, such as comparison and contrast, analysis and evaluation, and critique and synthesis, the writer can effectively merge ideas from different sources in a clear and coherent manner. Through the skillful application of these techniques, the writer can establish connections, draw parallels, and highlight the interrelationships of ideas, thereby creating a nuanced and sophisticated argument.

Examples serve as valuable tools in illustrating the principles and techniques of crafting a successful synthesis essay. For instance, consider a synthesis essay on the topic of climate change. In this essay, the writer integrates scientific research papers, political speeches, and personal testimony to create a comprehensive and persuasive argument for the urgent need for global action on climate change. By skillfully weaving together these diverse sources, the writer is able to present a multi-dimensional perspective on the issue while maintaining a clear and compelling narrative.

How to Write a Synthesis Essay: Step-by-Step Guide

In the process of crafting a synthesis essay, you will be tasked with combining information from multiple sources to create a cohesive and well-supported argument. This step-by-step guide will walk you through the process, providing helpful tips and examples along the way.

Step 1: Understand the Assignment

Before diving into the writing process, it is crucial to fully comprehend the assignment. Read through the prompt carefully, identifying the main question or topic, as well as any specific sources or guidelines provided. This will help you determine the scope and direction of your essay.

Step 2: Conduct Research

Once you have a solid grasp of the assignment, it’s time to gather information from various sources. This can include articles, books, interviews, or even online resources. Make sure to select sources that are reputable, current, and relevant to your topic. Take detailed notes as you read, highlighting key ideas and evidence.

Step 3: Develop a Thesis Statement

Based on your research, develop a clear and concise thesis statement that encapsulates your argument. This statement should present your position on the topic and preview the main points you will explore in your essay. Keep in mind that a strong thesis statement will guide the entire writing process.

Step 4: Create an Outline

Organize your thoughts and ideas by creating an outline for your essay. This will serve as a roadmap for your writing, ensuring that each point flows logically and effectively supports your thesis. Divide your essay into sections and subsections, assigning each one a specific focus.

Step 5: Write the Introduction

Begin your essay with a captivating introduction that grabs the reader’s attention. Provide some background information on the topic and present your thesis statement. Be sure to include a hook that entices the reader to continue reading.

Step 6: Craft the Body Paragraphs

The body of your essay should consist of several paragraphs, each dedicated to a specific point or subtopic. Begin each paragraph with a topic sentence that introduces the main idea, then support it with evidence from your sources. Be sure to cite your sources properly to give credit to the original authors.

Step 7: Write the Conclusion

Wrap up your essay with a strong conclusion that reinforces your thesis statement and summarizes your main points. Avoid introducing new information in this section, and instead focus on leaving a lasting impression on the reader.

Step 8: Revise and Edit

Once you have completed a draft of your essay, take the time to revise and edit it. Check for clarity, coherence, and overall effectiveness of your arguments. Also, review your grammar, spelling, and punctuation to ensure your essay is error-free.

Step 9: Proofread and Polish

Before submitting your final essay, proofread it one last time to catch any lingering errors. Pay attention to spelling, grammar, and punctuation mistakes. Additionally, ensure that your formatting and citations are consistent throughout the essay.

Step 10: Seek Feedback

Finally, seek feedback from others, such as peers, teachers, or writing tutors. Their fresh perspective can help you identify any areas that need improvement and provide valuable suggestions for strengthening your essay.

By following this step-by-step guide, you will be well-equipped to write a successful synthesis essay that effectively combines multiple sources and supports your argument. Remember to take your time, conduct thorough research, and carefully craft each section of your essay to achieve the best possible result.

Understanding the Purpose of a Synthesis Essay

Exploring the Rationale Behind Composing a Synthesis Paper

A synthesis essay is a unique form of academic writing that requires students to combine information from multiple sources to support a thesis statement. In this type of essay, the writer needs to analyze various perspectives and synthesize them into a coherent argument. The purpose of a synthesis essay is to demonstrate a deep understanding of a topic by presenting a well-structured and balanced synthesis of different viewpoints or approaches.

When writing a synthesis essay, it is essential to understand the purpose behind this type of assignment. The primary goal is not merely to summarize the information from the sources but to present an original perspective that emerges from the synthesis of these sources. By carefully analyzing and evaluating the information from various sources, students can develop a unique understanding of the topic and present their own insights.

Moreover, a synthesis essay allows students to demonstrate critical thinking and analytical skills. It requires them to evaluate the credibility and relevance of the sources used and to consider how different ideas and perspectives relate to one another. By carefully selecting and integrating information from diverse sources, students can create a cohesive argument that goes beyond a mere summary of the sources.

Another important purpose of a synthesis essay is to foster effective communication and persuasive writing skills. Through the synthesis process, students learn how to effectively convey their ideas and support them with evidence from the sources. They need to consider the audience and tailor their argument to appeal to the readers. By organizing their thoughts and ideas in a logical and coherent manner, students can make a persuasive case for their thesis statement.

In summary, the purpose of a synthesis essay is to demonstrate a deep understanding of a topic by synthesizing information from multiple sources into a cohesive argument. It requires students to analyze and evaluate various viewpoints and to develop their own unique perspective. Additionally, a synthesis essay cultivates critical thinking skills and effective communication abilities. By mastering the art of synthesis writing, students can become more proficient in academic research and persuasive writing, making their essays more compelling and insightful.

Choosing a Relevant Topic for Your Synthesis Essay

When embarking on a journey of writing a synthesis essay, one of the most crucial steps is selecting a pertinent topic that encompasses the essence of your discussion. This stage requires careful consideration and evaluation in order to ensure that you have a solid foundation on which to build your argument.

To begin, it is essential to understand that a relevant topic should address the central theme or question that you are exploring in your synthesis essay. It should encapsulate the diverse perspectives and ideas that you aim to synthesize in your composition. By choosing a topic that is pertinent to your thesis statement, you can create a cohesive and persuasive argument.

When selecting a topic, it is important to choose something that is not only interesting to you but also holds relevance to the current context. Consider the current societal issues, scientific advancements, or technological developments that are shaping the world around us. By delving into a topic that is timely and impactful, you can engage your readers and make your synthesis essay more compelling.

Furthermore, it is crucial to choose a topic that allows for a variety of sources and perspectives to be integrated into your essay. Look for subjects that have a wealth of research materials available from reputable sources such as academic journals, books, and established experts in the field. This will provide you with a diverse range of perspectives to consider and synthesize in your argument.

In conclusion, choosing a relevant topic for your synthesis essay is a critical step in the writing process. By selecting a topic that aligns with your thesis statement, holds relevance in the current context, and allows for a variety of perspectives to be included, you can create a well-rounded and persuasive synthesis essay that effectively conveys your argument.

Gathering and Evaluating Sources for Your Essay

When embarking on writing a synthesis essay, it is crucial to gather and evaluate reliable sources to support your arguments effectively. A successful essay depends on the quality and relevance of the sources you include. This section will provide you with some valuable tips on how to gather and evaluate sources for your essay.

1. Determine the scope of your essay: Before you start collecting sources, it is important to have a clear understanding of the scope and topic of your essay. This will help you narrow down your search and choose sources that are most relevant to your argument.

2. Use a variety of sources: In order to provide a well-rounded view on the topic, it is recommended to include a mix of primary and secondary sources. Primary sources can include original research studies, interviews, or firsthand accounts, while secondary sources can be scholarly articles, books, or reputable websites that analyze and interpret the primary sources.

3. Evaluate the credibility of the sources: It is essential to evaluate the credibility and reliability of the sources you find. Consider the author’s credentials, the reputation of the publication or website, and whether the information has been peer-reviewed or fact-checked. Avoid relying heavily on sources that lack authority or have a bias.

4. Check for currency: Ensure that the sources you choose are up to date and reflect the most current research and information on the topic. This is particularly important if you are writing about a rapidly evolving field or a current issue.

5. Take notes and keep track of your sources: As you gather your sources, it is crucial to take detailed notes and keep track of the bibliographic information. This will make it easier to properly credit your sources and create an accurate bibliography later on.

6. Consider diverse perspectives: While it can be tempting to rely on sources that align with your own views, it is important to consider diverse perspectives. Including sources with differing opinions can strengthen your argument and demonstrate that you have considered multiple viewpoints.

By following these tips and gathering a range of reliable sources, you will be well-equipped to write a compelling synthesis essay that is backed by solid evidence and argumentation.

Developing a Thesis Statement for Your Synthesis Essay

In the process of writing a synthesis essay, one of the most crucial steps is developing a strong thesis statement. A thesis statement sets the tone and direction for your essay, guiding the reader on what to expect and how the different sources you will be synthesizing contribute to your overall argument.

When developing a thesis statement for your synthesis essay, it is important to consider the main idea you want to convey and the point you want to make. Your thesis statement should be clear, concise, and specific, providing a roadmap for your essay and outlining the main arguments you will be making.

One approach to developing a thesis statement is to carefully analyze the sources you will be synthesizing and identify common themes or patterns. Look for similarities and differences among the sources and identify the main ideas that emerge. Your thesis statement can then highlight these main ideas and showcase how they intersect and contribute to your overall argument.

Another approach to developing a thesis statement is to consider the main arguments or perspectives presented in the sources and craft a statement that expresses your position on the topic. Your thesis statement can be a synthesis of these different perspectives, presenting a nuanced and balanced argument that incorporates multiple viewpoints.

Remember, a strong thesis statement is essential for a successful synthesis essay. It provides a clear roadmap for your essay and allows your reader to understand the main arguments you will be making. Take the time to carefully craft your thesis statement, ensuring it is specific, concise, and reflective of the main ideas you will be exploring in your essay.

Structuring Your Synthesis Essay for Effective Organization

Creating a well-structured synthesis essay is crucial for effective organization and a clear presentation of your ideas. A strong structure allows your readers to easily follow your argument and understand the connections between different sources and viewpoints. In this section, we will explore some key strategies for structuring your synthesis essay to ensure a cohesive and persuasive piece of writing.

1. Introduction: Start your essay with a compelling introduction that grabs your reader’s attention and clearly presents the topic you will be discussing. Provide some background information on the issue, highlight its significance, and state your thesis statement, which will guide your argument throughout the essay.

2. Body paragraphs: Divide your essay into several body paragraphs, each addressing a specific aspect of your topic. Begin each paragraph with a topic sentence that introduces the main idea or argument you will be discussing. Support your points with evidence from your sources, making sure to cite them properly. Use transitions between paragraphs and within sentences to create a smooth flow of ideas and to establish connections between different viewpoints.

3. Analysis and synthesis: While presenting the ideas from your sources, make sure to analyze and evaluate them critically. Discuss the strengths and weaknesses of each source, identify any biases or limitations, and consider how they contribute to your overall argument. Aim to synthesize the information from your sources, combining different perspectives to support your own viewpoint.

4. Counterarguments: Address and refute counterarguments to strengthen your argument and demonstrate a thorough understanding of the topic. Anticipate possible objections and provide evidence or reasoning to counter them. Acknowledging opposing viewpoints but explaining why they are flawed further strengthens your own argument and credibility.

5. Conclusion: Wrap up your essay with a strong conclusion that summarizes your main points and restates your thesis in a clear and compelling manner. Avoid introducing new information in the conclusion, but instead, emphasize the significance of your argument and its implications.

By structuring your synthesis essay in an organized and logical manner, you can ensure that your ideas are presented cohesively and persuasively. Remember to revise and edit your essay for clarity, coherence, and grammar, and proofread it carefully before submission. With a well-structured essay, you can effectively convey your argument and convince your readers of your viewpoint.

Writing and Revising Your Synthesis Essay

Crafting and fine-tuning your synthesis essay is an essential step in the writing process. Once you have conducted comprehensive research and gathered a plethora of sources, it’s time to consolidate your findings and present them in a cohesive and persuasive manner.

When it comes to writing your synthesis essay, it is crucial to lay a solid foundation. Begin by organizing your thoughts and ideas into an outline, creating a clear and logical structure for your essay. This framework will serve as a roadmap, guiding you through the writing process and ensuring that your arguments flow smoothly.

Once your outline is complete, you can begin the actual writing process. Start with a strong introduction that captures the reader’s attention and clearly states your thesis statement. From there, proceed to develop your ideas in a series of well-crafted paragraphs, each with its own topic sentence and supporting evidence.

As you write, remember to maintain a formal and academic tone, using appropriate language and avoiding slang or colloquialisms. Your synthesis essay should demonstrate your understanding of the topic and your ability to effectively analyze and synthesize information from a variety of sources.

Once you have completed your initial draft, it is essential to revise and edit your synthesis essay to ensure its clarity and coherence. Begin by reviewing the overall structure and organization of your essay. Check that your paragraphs flow smoothly and logically, and ensure that your thesis statement is well-supported by the evidence presented.

Next, focus on the content of your essay. Review each paragraph to ensure that it contributes to the overall argument and that the evidence presented is relevant and persuasive. Consider whether there are any gaps in your analysis or any areas that could benefit from further development.

In addition to content, pay attention to the style and mechanics of your writing. Check for grammatical and spelling errors, and ensure that your sentences are clear, concise, and varied. Consider the use of appropriate transitions to guide your reader through your essay and help them follow your line of reasoning.

Lastly, take the time to proofread your essay carefully. Read it aloud, or have someone else read it to you, to catch any errors or areas that could be strengthened. Remember, the revision process is an opportunity to refine and improve your essay, so take the time to make necessary changes and ensure that your synthesis is well-crafted and compelling.

If you know the topic that you should cover in your essay, you need to give it a title. Choose a title that will be catchy and simple. Don’t use too complicated words and too long words in the title so that the essay itself doesn’t seem attacked even though the readers haven’t read it yet.

If you already have a title, follow it in your research and try to stay on topic without covering too much unnecessary stuff. That way you will be ready to write the essay.

Do Research on The Topic and See What Information You Need

The next step is the one that bothers most students, but there is no need to panic. The research is done by searching several sources in which useful information can be found. Extract the most necessary information and then put it aside so that you know you need to use it during the writing.

Of course, he uses sources such as Google Scholar , sites where there are valuable texts with important information, or he uses already published works that are available on the Internet. That way you will have reliable information for a good start.

Create the Bullet Point and Start Writing the Essay

The next thing is to create a statement, that is, in which direction your attitude will go. Do your best to choose the right direction in order to have a successfully written essay. And then? Then start writing and use the information you found earlier.

With the help of the conclusion , an overview of everything that has been said is given, and often a solution and an epilogue are given to the topic that has been written about and that has been covered.

In this way, the reader is directed to think in the direction of the author as if this is the true and correct opinion presented in the essay itself.

Make a Check and Prepare It for Delivery

At the end, the entire reading must be checked. There may be typographical errors that cannot be seen in the essay itself. On the other hand, you may have left out something you wanted to say or gone too far off-topic.

The final reading is the last train that leads you to a successfully completed reading, that is, a successfully completed synthesis essay. Once you see that everything is in order, prepare the text for sending.

On This Page:

When you write a literature review or essay, you have to go beyond just summarizing the articles you’ve read – you need to synthesize the literature to show how it all fits together (and how your own research fits in).

Synthesizing simply means combining. Instead of summarizing the main points of each source in turn, you put together the ideas and findings of multiple sources in order to make an overall point.

At the most basic level, this involves looking for similarities and differences between your sources. Your synthesis should show the reader where the sources overlap and where they diverge.

Unsynthesized Example

Franz (2008) studied undergraduate online students. He looked at 17 females and 18 males and found that none of them liked APA. According to Franz, the evidence suggested that all students are reluctant to learn citations style. Perez (2010) also studies undergraduate students. She looked at 42 females and 50 males and found that males were significantly more inclined to use citation software ( p < .05). Findings suggest that females might graduate sooner. Goldstein (2012) looked at British undergraduates. Among a sample of 50, all females, all confident in their abilities to cite and were eager to write their dissertations.

Synthesized Example

Studies of undergraduate students reveal conflicting conclusions regarding relationships between advanced scholarly study and citation efficacy. Although Franz (2008) found that no participants enjoyed learning citation style, Goldstein (2012) determined in a larger study that all participants watched felt comfortable citing sources, suggesting that variables among participant and control group populations must be examined more closely. Although Perez (2010) expanded on Franz’s original study with a larger, more diverse sample…

Step 1: Organize your sources

After collecting the relevant literature, you’ve got a lot of information to work through, and no clear idea of how it all fits together.

Before you can start writing, you need to organize your notes in a way that allows you to see the relationships between sources.

One way to begin synthesizing the literature is to put your notes into a table. Depending on your topic and the type of literature you’re dealing with, there are a couple of different ways you can organize this.

Summary table

A summary table collates the key points of each source under consistent headings. This is a good approach if your sources tend to have a similar structure – for instance, if they’re all empirical papers.

Each row in the table lists one source, and each column identifies a specific part of the source. You can decide which headings to include based on what’s most relevant to the literature you’re dealing with.

For example, you might include columns for things like aims, methods, variables, population, sample size, and conclusion.

For each study, you briefly summarize each of these aspects. You can also include columns for your own evaluation and analysis.

The summary table gives you a quick overview of the key points of each source. This allows you to group sources by relevant similarities, as well as noticing important differences or contradictions in their findings.

Synthesis matrix

A synthesis matrix is useful when your sources are more varied in their purpose and structure – for example, when you’re dealing with books and essays making various different arguments about a topic.

Each column in the table lists one source. Each row is labeled with a specific concept, topic or theme that recurs across all or most of the sources.

Then, for each source, you summarize the main points or arguments related to the theme.

The purposes of the table is to identify the common points that connect the sources, as well as identifying points where they diverge or disagree.

Step 2: Outline your structure

Now you should have a clear overview of the main connections and differences between the sources you’ve read. Next, you need to decide how you’ll group them together and the order in which you’ll discuss them.

For shorter papers, your outline can just identify the focus of each paragraph; for longer papers, you might want to divide it into sections with headings.

There are a few different approaches you can take to help you structure your synthesis.

If your sources cover a broad time period, and you found patterns in how researchers approached the topic over time, you can organize your discussion chronologically .

That doesn’t mean you just summarize each paper in chronological order; instead, you should group articles into time periods and identify what they have in common, as well as signalling important turning points or developments in the literature.

If the literature covers various different topics, you can organize it thematically .

That means that each paragraph or section focuses on a specific theme and explains how that theme is approached in the literature.

Source Used with Permission: The Chicago School

If you’re drawing on literature from various different fields or they use a wide variety of research methods, you can organize your sources methodologically .

That means grouping together studies based on the type of research they did and discussing the findings that emerged from each method.

If your topic involves a debate between different schools of thought, you can organize it theoretically .

That means comparing the different theories that have been developed and grouping together papers based on the position or perspective they take on the topic, as well as evaluating which arguments are most convincing.

Step 3: Write paragraphs with topic sentences

What sets a synthesis apart from a summary is that it combines various sources. The easiest way to think about this is that each paragraph should discuss a few different sources, and you should be able to condense the overall point of the paragraph into one sentence.

This is called a topic sentence , and it usually appears at the start of the paragraph. The topic sentence signals what the whole paragraph is about; every sentence in the paragraph should be clearly related to it.

A topic sentence can be a simple summary of the paragraph’s content:

“Early research on [x] focused heavily on [y].”

For an effective synthesis, you can use topic sentences to link back to the previous paragraph, highlighting a point of debate or critique:

“Several scholars have pointed out the flaws in this approach.” “While recent research has attempted to address the problem, many of these studies have methodological flaws that limit their validity.”

By using topic sentences, you can ensure that your paragraphs are coherent and clearly show the connections between the articles you are discussing.

As you write your paragraphs, avoid quoting directly from sources: use your own words to explain the commonalities and differences that you found in the literature.

Don’t try to cover every single point from every single source – the key to synthesizing is to extract the most important and relevant information and combine it to give your reader an overall picture of the state of knowledge on your topic.

Step 4: Revise, edit and proofread

Like any other piece of academic writing, synthesizing literature doesn’t happen all in one go – it involves redrafting, revising, editing and proofreading your work.

Checklist for Synthesis

•   Do I introduce the paragraph with a clear, focused topic sentence?
•   Do I discuss more than one source in the paragraph?
•   Do I mention only the most relevant findings, rather than describing every part of the studies?
•   Do I discuss the similarities or differences between the sources, rather than summarizing each source in turn?
•   Do I put the findings or arguments of the sources in my own words?
•   Is the paragraph organized around a single idea?
•   Is the paragraph directly relevant to my research question or topic?
•   Is there a logical transition from this paragraph to the next one?

Metrics details

The central component in impactful healthcare decisions is evidence. Understanding how nurse leaders use evidence in their own managerial decision making is still limited. This mixed methods systematic review aimed to examine how evidence is used to solve leadership problems and to describe the measured and perceived effects of evidence-based leadership on nurse leaders and their performance, organizational, and clinical outcomes.

We included articles using any type of research design. We referred nurses, nurse managers or other nursing staff working in a healthcare context when they attempt to influence the behavior of individuals or a group in an organization using an evidence-based approach. Seven databases were searched until 11 November 2021. JBI Critical Appraisal Checklist for Quasi-experimental studies, JBI Critical Appraisal Checklist for Case Series, Mixed Methods Appraisal Tool were used to evaluate the Risk of bias in quasi-experimental studies, case series, mixed methods studies, respectively. The JBI approach to mixed methods systematic reviews was followed, and a parallel-results convergent approach to synthesis and integration was adopted.

Thirty-one publications were eligible for the analysis: case series ( n  = 27), mixed methods studies ( n  = 3) and quasi-experimental studies ( n  = 1). All studies were included regardless of methodological quality. Leadership problems were related to the implementation of knowledge into practice, the quality of nursing care and the resource availability. Organizational data was used in 27 studies to understand leadership problems, scientific evidence from literature was sought in 26 studies, and stakeholders’ views were explored in 24 studies. Perceived and measured effects of evidence-based leadership focused on nurses’ performance, organizational outcomes, and clinical outcomes. Economic data were not available.

Conclusions

This is the first systematic review to examine how evidence is used to solve leadership problems and to describe its measured and perceived effects from different sites. Although a variety of perceptions and effects were identified on nurses’ performance as well as on organizational and clinical outcomes, available knowledge concerning evidence-based leadership is currently insufficient. Therefore, more high-quality research and clinical trial designs are still needed.

Trail registration

The study was registered (PROSPERO CRD42021259624).

Peer Review reports

Global health demands have set new roles for nurse leaders [ 1 ].Nurse leaders are referred to as nurses, nurse managers, or other nursing staff working in a healthcare context who attempt to influence the behavior of individuals or a group based on goals that are congruent with organizational goals [ 2 ]. They are seen as professionals “armed with data and evidence, and a commitment to mentorship and education”, and as a group in which “leaders innovate, transform, and achieve quality outcomes for patients, health care professionals, organizations, and communities” [ 3 ]. Effective leadership occurs when team members critically follow leaders and are motivated by a leader’s decisions based on the organization’s requests and targets [ 4 ]. On the other hand, problems caused by poor leadership may also occur, regarding staff relations, stress, sickness, or retention [ 5 ]. Therefore, leadership requires an understanding of different problems to be solved using synthesizing evidence from research, clinical expertise, and stakeholders’ preferences [ 6 , 7 ]. If based on evidence, leadership decisions, also referred as leadership decision making [ 8 ], could ensure adequate staffing [ 7 , 9 ] and to produce sufficient and cost-effective care [ 10 ]. However, nurse leaders still rely on their decision making on their personal [ 11 ] and professional experience [ 10 ] over research evidence, which can lead to deficiencies in the quality and safety of care delivery [ 12 , 13 , 14 ]. As all nurses should demonstrate leadership in their profession, their leadership competencies should be strengthened [ 15 ].

Evidence-informed decision-making, referred to as evidence appraisal and application, and evaluation of decisions [ 16 ], has been recognized as one of the core competencies for leaders [ 17 , 18 ]. The role of evidence in nurse leaders’ managerial decision making has been promoted by public authorities [ 19 , 20 , 21 ]. Evidence-based management, another concept related to evidence-based leadership, has been used as the potential to improve healthcare services [ 22 ]. It can guide nursing leaders, in developing working conditions, staff retention, implementation practices, strategic planning, patient care, and success of leadership [ 13 ]. Collins and Holton [ 23 ] in their systematic review and meta-analysis examined 83 studies regarding leadership development interventions. They found that leadership training can result in significant improvement in participants’ skills, especially in knowledge level, although the training effects varied across studies. Cummings et al. [ 24 ] reviewed 100 papers (93 studies) and concluded that participation in leadership interventions had a positive impact on the development of a variety of leadership styles. Clavijo-Chamorro et al. [ 25 ] in their review of 11 studies focused on leadership-related factors that facilitate evidence implementation: teamwork, organizational structures, and transformational leadership. The role of nurse managers was to facilitate evidence-based practices by transforming contexts to motivate the staff and move toward a shared vision of change.

As far as we are aware, however, only a few systematic reviews have focused on evidence-based leadership or related concepts in the healthcare context aiming to analyse how nurse leaders themselves uses evidence in the decision-making process. Young [ 26 ] targeted definitions and acceptance of evidence-based management (EBMgt) in healthcare while Hasanpoor et al. [ 22 ] identified facilitators and barriers, sources of evidence used, and the role of evidence in the process of decision making. Both these reviews concluded that EBMgt was of great importance but used limitedly in healthcare settings due to a lack of time, a lack of research management activities, and policy constraints. A review by Williams [ 27 ] showed that the usage of evidence to support management in decision making is marginal due to a shortage of relevant evidence. Fraser [ 28 ] in their review further indicated that the potential evidence-based knowledge is not used in decision making by leaders as effectively as it could be. Non-use of evidence occurs and leaders base their decisions mainly on single studies, real-world evidence, and experts’ opinions [ 29 ]. Systematic reviews and meta-analyses rarely provide evidence of management-related interventions [ 30 ]. Tate et al. [ 31 ] concluded based on their systematic review and meta-analysis that the ability of nurse leaders to use and critically appraise research evidence may influence the way policy is enacted and how resources and staff are used to meet certain objectives set by policy. This can further influence staff and workforce outcomes. It is therefore important that nurse leaders have the capacity and motivation to use the strongest evidence available to effect change and guide their decision making [ 27 ].

Despite of a growing body of evidence, we found only one review focusing on the impact of evidence-based knowledge. Geert et al. [ 32 ] reviewed literature from 2007 to 2016 to understand the elements of design, delivery, and evaluation of leadership development interventions that are the most reliably linked to outcomes at the level of the individual and the organization, and that are of most benefit to patients. The authors concluded that it is possible to improve individual-level outcomes among leaders, such as knowledge, motivation, skills, and behavior change using evidence-based approaches. Some of the most effective interventions included, for example, interactive workshops, coaching, action learning, and mentoring. However, these authors found limited research evidence describing how nurse leaders themselves use evidence to support their managerial decisions in nursing and what the outcomes are.

To fill the knowledge gap and compliment to existing knowledgebase, in this mixed methods review we aimed to (1) examine what leadership problems nurse leaders solve using an evidence-based approach and (2) how they use evidence to solve these problems. We also explored (3) the measured and (4) perceived effects of the evidence-based leadership approach in healthcare settings. Both qualitative and quantitative components of the effects of evidence-based leadership were examined to provide greater insights into the available literature [ 33 ]. Together with the evidence-based leadership approach, and its impact on nursing [ 34 , 35 ], this knowledge gained in this review can be used to inform clinical policy or organizational decisions [ 33 ]. The study is registered (PROSPERO CRD42021259624). The methods used in this review were specified in advance and documented in a priori in a published protocol [ 36 ]. Key terms of the review and the search terms are defined in Table  1 (population, intervention, comparison, outcomes, context, other).

In this review, we used a mixed methods approach [ 37 ]. A mixed methods systematic review was selected as this approach has the potential to produce direct relevance to policy makers and practitioners [ 38 ]. Johnson and Onwuegbuzie [ 39 ] have defined mixed methods research as “the class of research in which the researcher mixes or combines quantitative and qualitative research techniques, methods, approaches, concepts or language into a single study.” Therefore, we combined quantitative and narrative analysis to appraise and synthesize empirical evidence, and we held them as equally important in informing clinical policy or organizational decisions [ 34 ]. In this review, a comprehensive synthesis of quantitative and qualitative data was performed first and then discussed in discussion part (parallel-results convergent design) [ 40 ]. We hoped that different type of analysis approaches could complement each other and deeper picture of the topic in line with our research questions could be gained [ 34 ].

Inclusion and exclusion criteria

Inclusion and exclusion criteria of the study are described in Table  1 .

Search strategy

A three-step search strategy was utilized. First, an initial limited search with #MEDLINE was undertaken, followed by analysis of the words used in the title, abstract, and the article’s key index terms. Second, the search strategy, including identified keywords and index terms, was adapted for each included data base and a second search was undertaken on 11 November 2021. The full search strategy for each database is described in Additional file 1 . Third, the reference list of all studies included in the review were screened for additional studies. No year limits or language restrictions were used.

Information sources

The database search included the following: CINAHL (EBSCO), Cochrane Library (academic database for medicine and health science and nursing), Embase (Elsevier), PsycINFO (EBSCO), PubMed (MEDLINE), Scopus (Elsevier) and Web of Science (academic database across all scientific and technical disciplines, ranging from medicine and social sciences to arts and humanities). These databases were selected as they represent typical databases in health care context. Subject headings from each of the databases were included in the search strategies. Boolean operators ‘AND’ and ‘OR’ were used to combine the search terms. An information specialist from the University of Turku Library was consulted in the formation of the search strategies.

Study selection

All identified citations were collated and uploaded into Covidence software (Covidence systematic review software, Veritas Health Innovation, Melbourne, Australia www.covidence.org ), and duplicates were removed by the software. Titles and abstracts were screened and assessed against the inclusion criteria independently by two reviewers out of four, and any discrepancies were resolved by the third reviewer (MV, KH, TL, WC). Studies meeting the inclusion criteria were retrieved in full and archived in Covidence. Access to one full-text article was lacking: the authors for one study were contacted about the missing full text, but no full text was received. All remaining hits of the included studies were retrieved and assessed independently against the inclusion criteria by two independent reviewers of four (MV, KH, TL, WC). Studies that did not meet the inclusion criteria were excluded, and the reasons for exclusion were recorded in Covidence. Any disagreements that arose between the reviewers were resolved through discussions with XL.

Assessment of methodological quality

Eligible studies were critically appraised by two independent reviewers (YT, SH). Standardized critical appraisal instruments based on the study design were used. First, quasi-experimental studies were assessed using the JBI Critical Appraisal Checklist for Quasi-experimental studies [ 44 ]. Second, case series were assessed using the JBI Critical Appraisal Checklist for Case Series [ 45 ]. Third, mixed methods studies were appraised using the Mixed Methods Appraisal Tool [ 46 ].

To increase inter-reviewer reliability, the review agreement was calculated (SH) [ 47 ]. A kappa greater than 0.8 was considered to represent a high level of agreement (0–0.1). In our data, the agreement was 0.75. Discrepancies raised between two reviewers were resolved through discussion and modifications and confirmed by XL. As an outcome, studies that met the inclusion criteria were proceeded to critical appraisal and assessed as suitable for inclusion in the review. The scores for each item and overall critical appraisal scores were presented.

Data extraction

For data extraction, specific tables were created. First, study characteristics (author(s), year, country, design, number of participants, setting) were extracted by two authors independently (JC, MV) and reviewed by TL. Second, descriptions of the interventions were extracted by two reviewers (JV, JC) using the structure of the TIDIeR (Template for Intervention Description and Replication) checklist (brief name, the goal of the intervention, material and procedure, models of delivery and location, dose, modification, adherence and fidelity) [ 48 ]. The extractions were confirmed (MV).

Third, due to a lack of effectiveness data and a wide heterogeneity between study designs and presentation of outcomes, no attempt was made to pool the quantitative data statistically; the findings of the quantitative data were presented in narrative form only [ 44 ]. The separate data extraction tables for each research question were designed specifically for this study. For both qualitative (and a qualitative component of mixed-method studies) and quantitative studies, the data were extracted and tabulated into text format according to preplanned research questions [ 36 ]. To test the quality of the tables and the data extraction process, three authors independently extracted the data from the first five studies (in alphabetical order). After that, the authors came together to share and determine whether their approaches of the data extraction were consistent with each other’s output and whether the content of each table was in line with research question. No reason was found to modify the data extraction tables or planned process. After a consensus of the data extraction process was reached, the data were extracted in pairs by independent reviewers (WC, TY, SH, GL). Any disagreements that arose between the reviewers were resolved through discussion and with a third reviewer (MV).

Data analysis

We were not able to conduct a meta-analysis due to a lack of effectiveness data based on clinical trials. Instead, we used inductive thematic analysis with constant comparison to answer the research question [ 46 , 49 ] using tabulated primary data from qualitative and quantitative studies as reported by the original authors in narrative form only [ 47 ]. In addition, the qualitizing process was used to transform quantitative data to qualitative data; this helped us to convert the whole data into themes and categories. After that we used the thematic analysis for the narrative data as follows. First, the text was carefully read, line by line, to reveal topics answering each specific review question (MV). Second, the data coding was conducted, and the themes in the data were formed by data categorization. The process of deriving the themes was inductive based on constant comparison [ 49 ]. The results of thematic analysis and data categorization was first described in narrative format and then the total number of studies was calculated where the specific category was identified (%).

Stakeholder involvement

The method of reporting stakeholders’ involvement follows the key components by [ 50 ]: (1) people involved, (2) geographical location, (3) how people were recruited, (4) format of involvement, (5) amount of involvement, (6) ethical approval, (7) financial compensation, and (8) methods for reporting involvement.

In our review, stakeholder involvement targeted nurses and nurse leader in China. Nurse Directors of two hospitals recommended potential participants who received a personal invitation letter from researchers to participate in a discussion meeting. Stakeholders’ participation was based on their own free will. Due to COVID-19, one online meeting (1 h) was organized (25 May 2022). Eleven participants joined the meeting. Ethical approval was not applied and no financial compensation was offered. At the end of the meeting, experiences of stakeholders’ involvement were explored.

The meeting started with an introductory presentation with power points. The rationale, methods, and preliminary review results were shared with the participants [ 51 ].The meeting continued with general questions for the participants: (1) Are you aware of the concepts of evidence-based practice or evidence-based leadership?; (2) How important is it to use evidence to support decisions among nurse leaders?; (3) How is the evidence-based approach used in hospital settings?; and (4) What type of evidence is currently used to support nurse leaders’ decision making (e.g. scientific literature, organizational data, stakeholder views)?

Two people took notes on the course and content of the conversation. The notes were later transcripted in verbatim, and the key points of the discussions were summarised. Although answers offered by the stakeholders were very short, the information was useful to validate the preliminary content of the results, add the rigorousness of the review, and obtain additional perspectives. A recommendation of the stakeholders was combined in the Discussion part of this review increasing the applicability of the review in the real world [ 50 ]. At the end of the discussion, the value of stakeholders’ involvement was asked. Participants shared that the experience of participating was unique and the topic of discussion was challenging. Two authors of the review group further represented stakeholders by working together with the research team throughout the review study.

Search results

From seven different electronic databases, 6053 citations were identified as being potentially relevant to the review. Then, 3133 duplicates were removed by an automation tool (Covidence: www.covidence.org ), and one was removed manually. The titles and abstracts of 3040 of citations were reviewed, and a total of 110 full texts were included (one extra citation was found on the reference list but later excluded). Based on the eligibility criteria, 31 studies (32 hits) were critically appraised and deemed suitable for inclusion in the review. The search results and selection process are presented in the PRISMA [ 52 ] flow diagram Fig.  1 . The full list of references for included studies can be find in Additional file 2 . To avoid confusion between articles of the reference list and studies included in the analysis, the studies included in the review are referred inside the article using the reference number of each study (e.g. ref 1, ref 2).

Search results and study selection and inclusion process [ 52 ]

Characteristics of included studies

The studies had multiple purposes, aiming to develop practice, implement a new approach, improve quality, or to develop a model. The 31 studies (across 32 hits) were case series studies ( n  = 27), mixed methods studies ( n  = 3) and a quasi-experimental study ( n  = 1). All studies were published between the years 2004 and 2021. The highest number of papers was published in year 2020.

Table  2 describes the characteristics of included studies and Additional file 3 offers a narrative description of the studies.

Methodological quality assessment

Quasi-experimental studies.

We had one quasi-experimental study (ref 31). All questions in the critical appraisal tool were applicable. The total score of the study was 8 (out of a possible 9). Only one response of the tool was ‘no’ because no control group was used in the study (see Additional file 4 for the critical appraisal of included studies).

Case series studies . A case series study is typically defined as a collection of subjects with common characteristics. The studies do not include a comparison group and are often based on prevalent cases and on a sample of convenience [ 53 ]. Munn et al. [ 45 ] further claim that case series are best described as observational studies, lacking experimental and randomized characteristics, being descriptive studies, without a control or comparator group. Out of 27 case series studies included in our review, the critical appraisal scores varied from 1 to 9. Five references were conference abstracts with empirical study results, which were scored from 1 to 3. Full reports of these studies were searched in electronic databases but not found. Critical appraisal scores for the remaining 22 studies ranged from 1 to 9 out of a possible score of 10. One question (Q3) was not applicable to 13 studies: “Were valid methods used for identification of the condition for all participants included in the case series?” Only two studies had clearly reported the demographic of the participants in the study (Q6). Twenty studies met Criteria 8 (“Were the outcomes or follow-up results of cases clearly reported?”) and 18 studies met Criteria 7 (“Q7: Was there clear reporting of clinical information of the participants?”) (see Additional file 4 for the critical appraisal of included studies).

Mixed-methods studies

Mixed-methods studies involve a combination of qualitative and quantitative methods. This is a common design and includes convergent design, sequential explanatory design, and sequential exploratory design [ 46 ]. There were three mixed-methods studies. The critical appraisal scores for the three studies ranged from 60 to 100% out of a possible 100%. Two studies met all the criteria, while one study fulfilled 60% of the scored criteria due to a lack of information to understand the relevance of the sampling strategy well enough to address the research question (Q4.1) or to determine whether the risk of nonresponse bias was low (Q4.4) (see Additional file 4 for the critical appraisal of included studies).

Intervention or program components

The intervention of program components were categorized and described using the TiDier checklist: name and goal, theory or background, material, procedure, provider, models of delivery, location, dose, modification, and adherence and fidelity [ 48 ]. A description of intervention in each study is described in Additional file 5 and a narrative description in Additional file 6 .

Leadership problems

In line with the inclusion criteria, data for the leadership problems were categorized in all 31 included studies (see Additional file 7 for leadership problems). Three types of leadership problems were identified: implementation of knowledge into practice, the quality of clinical care, and resources in nursing care. A narrative summary of the results is reported below.

Implementing knowledge into practice

Eleven studies (35%) aimed to solve leadership problems related to implementation of knowledge into practice. Studies showed how to support nurses in evidence-based implementation (EBP) (ref 3, ref 5), how to engage nurses in using evidence in practice (ref 4), how to convey the importance of EBP (ref 22) or how to change practice (ref 4). Other problems were how to facilitate nurses to use guideline recommendations (ref 7) and how nurses can make evidence-informed decisions (ref 8). General concerns also included the linkage between theory and practice (ref 1) as well as how to implement the EBP model in practice (ref 6). In addition, studies were motivated by the need for revisions or updates of protocols to improve clinical practice (ref 10) as well as the need to standardize nursing activities (ref 11, ref 14).

The quality of the care

Thirteen (42%) focused on solving problems related to the quality of clinical care. In these studies, a high number of catheter infections led a lack of achievement of organizational goals (ref 2, ref 9). A need to reduce patient symptoms in stem cell transplant patients undergoing high-dose chemotherapy (ref 24) was also one of the problems to be solved. In addition, the projects focused on how to prevent pressure ulcers (ref 26, ref 29), how to enhance the quality of cancer treatment (ref 25) and how to reduce the need for invasive constipation treatment (ref 30). Concerns about patient safety (ref 15), high fall rates (ref 16, ref 19), dissatisfaction of patients (ref 16, ref 18) and nurses (ref 16, ref 30) were also problems that had initiated the projects. Studies addressed concerns about how to promote good contingency care in residential aged care homes (ref 20) and about how to increase recognition of human trafficking problems in healthcare (ref 21).

Resources in nursing care

Nurse leaders identified problems in their resources, especially in staffing problems. These problems were identified in seven studies (23%), which involved concerns about how to prevent nurses from leaving the job (ref 31), how to ensure appropriate recruitment, staffing and retaining of nurses (ref 13) and how to decrease nurses’ burden and time spent on nursing activities (ref 12). Leadership turnover was also reported as a source of dissatisfaction (ref 17); studies addressed a lack of structured transition and training programs, which led to turnover (ref 23), as well as how to improve intershift handoff among nurses (ref 28). Optimal design for new hospitals was also examined (ref 27).

Main features of evidence-based leadership

Out of 31 studies, 17 (55%) included all four domains of an evidence-based leadership approach, and four studies (13%) included evidence of critical appraisal of the results (see Additional file 8 for the main features of evidence-based Leadership) (ref 11, ref 14, ref 23, ref 27).

Organizational evidence

Twenty-seven studies (87%) reported how organizational evidence was collected and used to solve leadership problems (ref 2). Retrospective chart reviews (ref 5), a review of the extent of specific incidents (ref 19), and chart auditing (ref 7, ref 25) were conducted. A gap between guideline recommendations and actual care was identified using organizational data (ref 7) while the percentage of nurses’ working time spent on patient care was analyzed using an electronic charting system (ref 12). Internal data (ref 22), institutional data, and programming metrics were also analyzed to understand the development of the nurse workforce (ref 13).

Surveys (ref 3, ref 25), interviews (ref 3, ref 25) and group reviews (ref 18) were used to better understand the leadership problem to be solved. Employee opinion surveys on leadership (ref 17), a nurse satisfaction survey (ref 30) and a variety of reporting templates were used for the data collection (ref 28) reported. Sometimes, leadership problems were identified by evidence facilitators or a PI’s team who worked with staff members (ref 15, ref 17). Problems in clinical practice were also identified by the Nursing Professional Council (ref 14), managers (ref 26) or nurses themselves (ref 24). Current practices were reviewed (ref 29) and a gap analysis was conducted (ref 4, ref 16, ref 23) together with SWOT analysis (ref 16). In addition, hospital mission and vision statements, research culture established and the proportion of nursing alumni with formal EBP training were analyzed (ref 5). On the other hand, it was stated that no systematic hospital-specific sources of data regarding job satisfaction or organizational commitment were used (ref 31). In addition, statements of organizational analysis were used on a general level only (ref 1).

Scientific evidence identified

Twenty-six studies (84%) reported the use of scientific evidence in their evidence-based leadership processes. A literature search was conducted (ref 21) and questions, PICO, and keywords were identified (ref 4) in collaboration with a librarian. Electronic databases, including PubMed (ref 14, ref 31), Cochrane, and EMBASE (ref 31) were searched. Galiano (ref 6) used Wiley Online Library, Elsevier, CINAHL, Health Source: Nursing/Academic Edition, PubMed, and the Cochrane Library while Hoke (ref 11) conducted an electronic search using CINAHL and PubMed to retrieve articles.

Identified journals were reviewed manually (ref 31). The findings were summarized using ‘elevator speech’ (ref 4). In a study by Gifford et al. (ref 9) evidence facilitators worked with participants to access, appraise, and adapt the research evidence to the organizational context. Ostaszkiewicz (ref 20) conducted a scoping review of literature and identified and reviewed frameworks and policy documents about the topic and the quality standards. Further, a team of nursing administrators, directors, staff nurses, and a patient representative reviewed the literature and made recommendations for practice changes.

Clinical practice guidelines were also used to offer scientific evidence (ref 7, ref 19). Evidence was further retrieved from a combination of nursing policies, guidelines, journal articles, and textbooks (ref 12) as well as from published guidelines and literature (ref 13). Internal evidence, professional practice knowledge, relevant theories and models were synthesized (ref 24) while other study (ref 25) reviewed individual studies, synthesized with systematic reviews or clinical practice guidelines. The team reviewed the research evidence (ref 3, ref 15) or conducted a literature review (ref 22, ref 28, ref 29), a literature search (ref 27), a systematic review (ref 23), a review of the literature (ref 30) or ‘the scholarly literature was reviewed’ (ref 18). In addition, ‘an extensive literature review of evidence-based best practices was carried out’ (ref 10). However, detailed description how the review was conducted was lacking.

Views of stakeholders

A total of 24 studies (77%) reported methods for how the views of stakeholders, i.e., professionals or experts, were considered. Support to run this study was received from nursing leadership and multidisciplinary teams (ref 29). Experts and stakeholders joined the study team in some cases (ref 25, ref 30), and in other studies, their opinions were sought to facilitate project success (ref 3). Sometimes a steering committee was formed by a Chief Nursing Officer and Clinical Practice Specialists (ref 2). More specifically, stakeholders’ views were considered using interviews, workshops and follow-up teleconferences (ref 7). The literature review was discussed with colleagues (ref 11), and feedback and support from physicians as well as the consensus of staff were sought (ref 16).

A summary of the project findings and suggestions for the studies were discussed at 90-minute weekly meetings by 11 charge nurses. Nurse executive directors were consulted over a 10-week period (ref 31). An implementation team (nurse, dietician, physiotherapist, occupational therapist) was formed to support the implementation of evidence-based prevention measures (ref 26). Stakeholders volunteered to join in the pilot implementation (ref 28) or a stakeholder team met to determine the best strategy for change management, shortcomings in evidence-based criteria were discussed, and strategies to address those areas were planned (ref 5). Nursing leaders, staff members (ref 22), ‘process owners (ref 18) and program team members (ref 18, ref 19, ref 24) met regularly to discuss the problems. Critical input was sought from clinical educators, physicians, nutritionists, pharmacists, and nurse managers (ref 24). The unit director and senior nursing staff reviewed the contents of the product, and the final version of clinical pathways were reviewed and approved by the Quality Control Commission of the Nursing Department (ref 12). In addition, two co-design workshops with 18 residential aged care stakeholders were organized to explore their perspectives about factors to include in a model prototype (ref 20). Further, an agreement of stakeholders in implementing continuous quality services within an open relationship was conducted (ref 1).

Critical appraisal

In five studies (16%), a critical appraisal targeting the literature search was carried out. The appraisals were conducted by interns and teams who critiqued the evidence (ref 4). In Hoke’s study, four areas that had emerged in the literature were critically reviewed (ref 11). Other methods were to ‘critically appraise the search results’ (ref 14). Journal club team meetings (ref 23) were organized to grade the level and quality of evidence and the team ‘critically appraised relevant evidence’ (ref 27). On the other hand, the studies lacked details of how the appraisals were done in each study.

The perceived effects of evidence-based leadership

Perceived effects of evidence-based leadership on nurses’ performance.

Eleven studies (35%) described perceived effects of evidence-based leadership on nurses’ performance (see Additional file 9 for perceived effects of evidence-based leadership), which were categorized in four groups: awareness and knowledge, competence, ability to understand patients’ needs, and engagement. First, regarding ‘awareness and knowledge’, different projects provided nurses with new learning opportunities (ref 3). Staff’s knowledge (ref 20, ref 28), skills, and education levels improved (ref 20), as did nurses’ knowledge comprehension (ref 21). Second, interventions and approaches focusing on management and leadership positively influenced participants’ competence level to improve the quality of services. Their confidence level (ref 1) and motivation to change practice increased, self-esteem improved, and they were more positive and enthusiastic in their work (ref 22). Third, some nurses were relieved that they had learned to better handle patients’ needs (ref 25). For example, a systematic work approach increased nurses’ awareness of the patients who were at risk of developing health problems (ref 26). And last, nurse leaders were more engaged with staff, encouraging them to adopt the new practices and recognizing their efforts to change (ref 8).

Perceived effects on organizational outcomes

Nine studies (29%) described the perceived effects of evidence-based leadership on organizational outcomes (see Additional file 9 for perceived effects of evidence-based leadership). These were categorized into three groups: use of resources, staff commitment, and team effort. First, more appropriate use of resources was reported (ref 15, ref 20), and working time was more efficiently used (ref 16). In generally, a structured approach made implementing change more manageable (ref 1). On the other hand, in the beginning of the change process, the feedback from nurses was unfavorable, and they experienced discomfort in the new work style (ref 29). New approaches were also perceived as time consuming (ref 3). Second, nurse leaders believed that fewer nursing staff than expected left the organization over the course of the study (ref 31). Third, the project helped staff in their efforts to make changes, and it validated the importance of working as a team (ref 7). Collaboration and support between the nurses increased (ref 26). On the other hand, new work style caused challenges in teamwork (ref 3).

Perceived effects on clinical outcomes

Five studies (16%) reported the perceived effects of evidence-based leadership on clinical outcomes (see Additional file 9 for perceived effects of evidence-based leadership), which were categorized in two groups: general patient outcomes and specific clinical outcomes. First, in general, the project assisted in connecting the guideline recommendations and patient outcomes (ref 7). The project was good for the patients in general, and especially to improve patient safety (ref 16). On the other hand, some nurses thought that the new working style did not work at all for patients (ref 28). Second, the new approach used assisted in optimizing patients’ clinical problems and person-centered care (ref 20). Bowel management, for example, received very good feedback (ref 30).

The measured effects of evidence-based leadership

The measured effects on nurses’ performance.

Data were obtained from 20 studies (65%) (see Additional file 10 for measured effects of evidence-based leadership) and categorized nurse performance outcomes for three groups: awareness and knowledge, engagement, and satisfaction. First, six studies (19%) measured the awareness and knowledge levels of participants. Internship for staff nurses was beneficial to help participants to understand the process for using evidence-based practice and to grow professionally, to stimulate for innovative thinking, to give knowledge needed to use evidence-based practice to answer clinical questions, and to make possible to complete an evidence-based practice project (ref 3). Regarding implementation program of evidence-based practice, those with formal EBP training showed an improvement in knowledge, attitude, confidence, awareness and application after intervention (ref 3, ref 11, ref 20, ref 23, ref 25). On the contrary, in other study, attitude towards EBP remained stable ( p  = 0.543). and those who applied EBP decreased although no significant differences over the years ( p  = 0.879) (ref 6).

Second, 10 studies (35%) described nurses’ engagement to new practices (ref 5, ref 6, ref 7, ref 10, ref 16, ref 17, ref 18, ref 21, ref 25, ref 27). 9 studies (29%) studies reported that there was an improvement of compliance level of participants (ref 6, ref 7, ref 10, ref 16, ref 17, ref 18, ref 21, ref 25, ref 27). On the contrary, in DeLeskey’s (ref 5) study, although improvement was found in post-operative nausea and vomiting’s (PONV) risk factors documented’ (2.5–63%), and ’risk factors communicated among anaesthesia and surgical staff’ (0–62%), the improvement did not achieve the goal. The reason was a limited improvement was analysed. It was noted that only those patients who had been seen by the pre-admission testing nurse had risk assessments completed. Appropriate treatment/prophylaxis increased from 69 to 77%, and from 30 to 49%; routine assessment for PONV/rescue treatment 97% and 100% was both at 100% following the project. The results were discussed with staff but further reasons for a lack of engagement in nursing care was not reported.

And third, six studies (19%) reported nurses’ satisfaction with project outcomes. The study results showed that using evidence in managerial decisions improved nurses’ satisfaction and attitudes toward their organization ( P  < 0.05) (ref 31). Nurses’ overall job satisfaction improved as well (ref 17). Nurses’ satisfaction with usability of the electronic charting system significantly improved after introduction of the intervention (ref 12). In handoff project in seven hospitals, improvement was reported in all satisfaction indicators used in the study although improvement level varied in different units (ref 28). In addition, positive changes were reported in nurses’ ability to autonomously perform their job (“How satisfied are you with the tools and resources available for you treat and prevent patient constipation?” (54%, n  = 17 vs. 92%, n  = 35, p  < 0.001) (ref 30).

The measured effects on organizational outcomes

Thirteen studies (42%) described the effects of a project on organizational outcomes (see Additional file 10 for measured effects of evidence-based leadership), which were categorized in two groups: staff compliance, and changes in practices. First, studies reported improved organizational outcomes due to staff better compliance in care (ref 4, ref 13, ref 17, ref 23, ref 27, ref 31). Second, changes in organization practices were also described (ref 11) like changes in patient documentation (ref 12, ref 21). Van Orne (ref 30) found a statistically significant reduction in the average rate of invasive medication administration between pre-intervention and post-intervention ( p  = 0.01). Salvador (ref 24) also reported an improvement in a proactive approach to mucositis prevention with an evidence-based oral care guide. On the contrary, concerns were also raised such as not enough time for new bedside report (ref 16) or a lack of improvement of assessment of diabetic ulcer (ref 8).

The measured effects on clinical outcomes

A variety of improvements in clinical outcomes were reported (see Additional file 10 for measured effects of evidence-based leadership): improvement in patient clinical status and satisfaction level. First, a variety of improvement in patient clinical status was reported. improvement in Incidence of CAUTI decreased 27.8% between 2015 and 2019 (ref 2) while a patient-centered quality improvement project reduced CAUTI rates to 0 (ref 10). A significant decrease in transmission rate of MRSA transmission was also reported (ref 27) and in other study incidences of CLABSIs dropped following of CHG bathing (ref 14). Further, it was possible to decrease patient nausea from 18 to 5% and vomiting to 0% (ref 5) while the percentage of patients who left the hospital without being seen was below 2% after the project (ref 17). In addition, a significant reduction in the prevalence of pressure ulcers was found (ref 26, ref 29) and a significant reduction of mucositis severity/distress was achieved (ref 24). Patient falls rate decreased (ref 15, ref 16, ref 19, ref 27).

Second, patient satisfaction level after project implementation improved (ref 28). The scale assessing healthcare providers by consumers showed improvement, but the changes were not statistically significant. Improvement in an emergency department leadership model and in methods of communication with patients improved patient satisfaction scores by 600% (ref 17). In addition, new evidence-based unit improved patient experiences about the unit although not all items improved significantly (ref 18).

Stakeholder involvement in the mixed-method review

To ensure stakeholders’ involvement in the review, the real-world relevance of our research [ 53 ], achieve a higher level of meaning in our review results, and gain new perspectives on our preliminary findings [ 50 ], a meeting with 11 stakeholders was organized. First, we asked if participants were aware of the concepts of evidence-based practice or evidence-based leadership. Responses revealed that participants were familiar with the concept of evidence-based practice, but the topic of evidence-based leadership was totally new. Examples of nurses and nurse leaders’ responses are as follows: “I have heard a concept of evidence-based practice but never a concept of evidence-based leadership.” Another participant described: “I have heard it [evidence-based leadership] but I do not understand what it means.”

Second, as stakeholder involvement is beneficial to the relevance and impact of health research [ 54 ], we asked how important evidence is to them in supporting decisions in health care services. One participant described as follows: “Using evidence in decisions is crucial to the wards and also to the entire hospital.” Third, we asked how the evidence-based approach is used in hospital settings. Participants expressed that literature is commonly used to solve clinical problems in patient care but not to solve leadership problems. “In [patient] medication and care, clinical guidelines are regularly used. However, I am aware only a few cases where evidence has been sought to solve leadership problems.”

And last, we asked what type of evidence is currently used to support nurse leaders’ decision making (e.g. scientific literature, organizational data, stakeholder views)? The participants were aware that different types of information were collected in their organization on a daily basis (e.g. patient satisfaction surveys). However, the information was seldom used to support decision making because nurse leaders did not know how to access this information. Even so, the participants agreed that the use of evidence from different sources was important in approaching any leadership or managerial problems in the organization. Participants also suggested that all nurse leaders should receive systematic training related to the topic; this could support the daily use of the evidence-based approach.

To our knowledge, this article represents the first mixed-methods systematic review to examine leadership problems, how evidence is used to solve these problems and what the perceived and measured effects of evidence-based leadership are on nurse leaders and their performance, organizational, and clinical outcomes. This review has two key findings. First, the available research data suggests that evidence-based leadership has potential in the healthcare context, not only to improve knowledge and skills among nurses, but also to improve organizational outcomes and the quality of patient care. Second, remarkably little published research was found to explore the effects of evidence-based leadership with an efficient trial design. We validated the preliminary results with nurse stakeholders, and confirmed that nursing staff, especially nurse leaders, were not familiar with the concept of evidence-based leadership, nor were they used to implementing evidence into their leadership decisions. Our data was based on many databases, and we screened a large number of studies. We also checked existing registers and databases and found no registered or ongoing similar reviews being conducted. Therefore, our results may not change in the near future.

We found that after identifying the leadership problems, 26 (84%) studies out of 31 used organizational data, 25 (81%) studies used scientific evidence from the literature, and 21 (68%) studies considered the views of stakeholders in attempting to understand specific leadership problems more deeply. However, only four studies critically appraised any of these findings. Considering previous critical statements of nurse leaders’ use of evidence in their decision making [ 14 , 30 , 31 , 34 , 55 ], our results are still quite promising.

Our results support a previous systematic review by Geert et al. [ 32 ], which concluded that it is possible to improve leaders’ individual-level outcomes, such as knowledge, motivation, skills, and behavior change using evidence-based approaches. Collins and Holton [ 23 ] particularly found that leadership training resulted in significant knowledge and skill improvements, although the effects varied widely across studies. In our study, evidence-based leadership was seen to enable changes in clinical practice, especially in patient care. On the other hand, we understand that not all efforts to changes were successful [ 56 , 57 , 58 ]. An evidence-based approach causes negative attitudes and feelings. Negative emotions in participants have also been reported due to changes, such as discomfort with a new working style [ 59 ]. Another study reported inconvenience in using a new intervention and its potential risks for patient confidentiality. Sometimes making changes is more time consuming than continuing with current practice [ 60 ]. These findings may partially explain why new interventions or program do not always fully achieve their goals. On the other hand, Dubose et al. [ 61 ] state that, if prepared with knowledge of resistance, nurse leaders could minimize the potential negative consequences and capitalize on a powerful impact of change adaptation.

We found that only six studies used a specific model or theory to understand the mechanism of change that could guide leadership practices. Participants’ reactions to new approaches may be an important factor in predicting how a new intervention will be implemented into clinical practice. Therefore, stronger effort should be put to better understanding the use of evidence, how participants’ reactions and emotions or practice changes could be predicted or supported using appropriate models or theories, and how using these models are linked with leadership outcomes. In this task, nurse leaders have an important role. At the same time, more responsibilities in developing health services have been put on the shoulders of nurse leaders who may already be suffering under pressure and increased burden at work. Working in a leadership position may also lead to role conflict. A study by Lalleman et al. [ 62 ] found that nurses were used to helping other people, often in ad hoc situations. The helping attitude of nurses combined with structured managerial role may cause dilemmas, which may lead to stress. Many nurse leaders opt to leave their positions less than 5 years [ 63 ].To better fulfill the requirements of health services in the future, the role of nurse leaders in evidence-based leadership needs to be developed further to avoid ethical and practical dilemmas in their leadership practices.

It is worth noting that the perceived and measured effects did not offer strong support to each other but rather opened a new venue to understand the evidence-based leadership. Specifically, the perceived effects did not support to measured effects (competence, ability to understand patients’ needs, use of resources, team effort, and specific clinical outcomes) while the measured effects could not support to perceived effects (nurse’s performance satisfaction, changes in practices, and clinical outcomes satisfaction). These findings may indicate that different outcomes appear if the effects of evidence-based leadership are looked at using different methodological approach. Future study is encouraged using well-designed study method including mixed-method study to examine the consistency between perceived and measured effects of evidence-based leadership in health care.

There is a potential in nursing to support change by demonstrating conceptual and operational commitment to research-based practices [ 64 ]. Nurse leaders are well positioned to influence and lead professional governance, quality improvement, service transformation, change and shared governance [ 65 ]. In this task, evidence-based leadership could be a key in solving deficiencies in the quality, safety of care [ 14 ] and inefficiencies in healthcare delivery [ 12 , 13 ]. As WHO has revealed, there are about 28 million nurses worldwide, and the demand of nurses will put nurse resources into the specific spotlight [ 1 ]. Indeed, evidence could be used to find solutions for how to solve economic deficits or other problems using leadership skills. This is important as, when nurses are able to show leadership and control in their own work, they are less likely to leave their jobs [ 66 ]. On the other hand, based on our discussions with stakeholders, nurse leaders are not used to using evidence in their own work. Further, evidence-based leadership is not possible if nurse leaders do not have access to a relevant, robust body of evidence, adequate funding, resources, and organizational support, and evidence-informed decision making may only offer short-term solutions [ 55 ]. We still believe that implementing evidence-based strategies into the work of nurse leaders may create opportunities to protect this critical workforce from burnout or leaving the field [ 67 ]. However, the role of the evidence-based approach for nurse leaders in solving these problems is still a key question.

Limitations

This study aimed to use a broad search strategy to ensure a comprehensive review but, nevertheless, limitations exist: we may have missed studies not included in the major international databases. To keep search results manageable, we did not use specific databases to systematically search grey literature although it is a rich source of evidence used in systematic reviews and meta-analysis [ 68 ]. We still included published conference abstract/proceedings, which appeared in our scientific databases. It has been stated that conference abstracts and proceedings with empirical study results make up a great part of studies cited in systematic reviews [ 69 ]. At the same time, a limited space reserved for published conference publications can lead to methodological issues reducing the validity of the review results [ 68 ]. We also found that the great number of studies were carried out in western countries, restricting the generalizability of the results outside of English language countries. The study interventions and outcomes were too different across studies to be meaningfully pooled using statistical methods. Thus, our narrative synthesis could hypothetically be biased. To increase transparency of the data and all decisions made, the data, its categorization and conclusions are based on original studies and presented in separate tables and can be found in Additional files. Regarding a methodological approach [ 34 ], we used a mixed methods systematic review, with the core intention of combining quantitative and qualitative data from primary studies. The aim was to create a breadth and depth of understanding that could confirm to or dispute evidence and ultimately answer the review question posed [ 34 , 70 ]. Although the method is gaining traction due to its usefulness and practicality, guidance in combining quantitative and qualitative data in mixed methods systematic reviews is still limited at the theoretical stage [ 40 ]. As an outcome, it could be argued that other methodologies, for example, an integrative review, could have been used in our review to combine diverse methodologies [ 71 ]. We still believe that the results of this mixed method review may have an added value when compared with previous systematic reviews concerning leadership and an evidence-based approach.

Our mixed methods review fills the gap regarding how nurse leaders themselves use evidence to guide their leadership role and what the measured and perceived impact of evidence-based leadership is in nursing. Although the scarcity of controlled studies on this topic is concerning, the available research data suggest that evidence-based leadership intervention can improve nurse performance, organizational outcomes, and patient outcomes. Leadership problems are also well recognized in healthcare settings. More knowledge and a deeper understanding of the role of nurse leaders, and how they can use evidence in their own managerial leadership decisions, is still needed. Despite the limited number of studies, we assume that this narrative synthesis can provide a good foundation for how to develop evidence-based leadership in the future.

Implications

Based on our review results, several implications can be recommended. First, the future of nursing success depends on knowledgeable, capable, and strong leaders. Therefore, nurse leaders worldwide need to be educated about the best ways to manage challenging situations in healthcare contexts using an evidence-based approach in their decisions. This recommendation was also proposed by nurses and nurse leaders during our discussion meeting with stakeholders.

Second, curriculums in educational organizations and on-the-job training for nurse leaders should be updated to support general understanding how to use evidence in leadership decisions. And third, patients and family members should be more involved in the evidence-based approach. It is therefore important that nurse leaders learn how patients’ and family members’ views as stakeholders are better considered as part of the evidence-based leadership approach.

Future studies should be prioritized as follows: establishment of clear parameters for what constitutes and measures evidence-based leadership; use of theories or models in research to inform mechanisms how to effectively change the practice; conducting robust effectiveness studies using trial designs to evaluate the impact of evidence-based leadership; studying the role of patient and family members in improving the quality of clinical care; and investigating the financial impact of the use of evidence-based leadership approach within respective healthcare systems.

Differences between the original protocol

We modified criteria for the included studies: we included published conference abstracts/proceedings, which form a relatively broad knowledge base in scientific knowledge. We originally planned to conduct a survey with open-ended questions followed by a face-to-face meeting to discuss the preliminary results of the review. However, to avoid extra burden in nurses due to COVID-19, we decided to limit the validation process to the online discussion only.
