When you look for areas where your sources agree or disagree and try to draw broader conclusions about your topic based on what your sources say, you are engaging in synthesis. Writing a research paper usually requires synthesizing the available sources in order to provide new insight or a different perspective into your particular topic (as opposed to simply restating what each individual source says about your research topic).

Note that synthesizing is not the same as summarizing.  

  • A summary restates the information in one or more sources without providing new insight or reaching new conclusions.
  • A synthesis draws on multiple sources to reach a broader conclusion.

There are two types of syntheses: explanatory syntheses and argumentative syntheses . Explanatory syntheses seek to bring sources together to explain a perspective and the reasoning behind it. Argumentative syntheses seek to bring sources together to make an argument. Both types of synthesis involve looking for relationships between sources and drawing conclusions.

In order to successfully synthesize your sources, you might begin by grouping your sources by topic and looking for connections. For example, if you were researching the pros and cons of encouraging healthy eating in children, you would want to separate your sources to find which ones agree with each other and which ones disagree.

After you have a good idea of what your sources are saying, you want to construct your body paragraphs in a way that acknowledges different sources and highlights where you can draw new conclusions.

As you continue synthesizing, here are a few points to remember:

  • Don’t force a relationship between sources if there isn’t one. Not all of your sources have to complement one another.
  • Do your best to highlight the relationships between sources in very clear ways.
  • Don’t ignore any outliers in your research. It’s important to take note of every perspective (even those that disagree with your broader conclusions).

Example Syntheses

Below are two examples of synthesis: one where synthesis is NOT utilized well, and one where it is.

Parents are always trying to find ways to encourage healthy eating in their children. Elena Pearl Ben-Joseph, a doctor and writer for KidsHealth , encourages parents to be role models for their children by not dieting or vocalizing concerns about their body image. The first popular diet began in 1863. William Banting named it the “Banting” diet after himself, and it consisted of eating fruits, vegetables, meat, and dry wine. Despite the fact that dieting has been around for over a hundred and fifty years, parents should not diet because it hinders children’s understanding of healthy eating.

In this sample paragraph, the paragraph begins with one idea then drastically shifts to another. Rather than comparing the sources, the author simply describes their content. This leads the paragraph to veer in an different direction at the end, and it prevents the paragraph from expressing any strong arguments or conclusions.

An example of a stronger synthesis can be found below.

Parents are always trying to find ways to encourage healthy eating in their children. Different scientists and educators have different strategies for promoting a well-rounded diet while still encouraging body positivity in children. David R. Just and Joseph Price suggest in their article “Using Incentives to Encourage Healthy Eating in Children” that children are more likely to eat fruits and vegetables if they are given a reward (855-856). Similarly, Elena Pearl Ben-Joseph, a doctor and writer for Kids Health , encourages parents to be role models for their children. She states that “parents who are always dieting or complaining about their bodies may foster these same negative feelings in their kids. Try to keep a positive approach about food” (Ben-Joseph). Martha J. Nepper and Weiwen Chai support Ben-Joseph’s suggestions in their article “Parents’ Barriers and Strategies to Promote Healthy Eating among School-age Children.” Nepper and Chai note, “Parents felt that patience, consistency, educating themselves on proper nutrition, and having more healthy foods available in the home were important strategies when developing healthy eating habits for their children.” By following some of these ideas, parents can help their children develop healthy eating habits while still maintaining body positivity.

In this example, the author puts different sources in conversation with one another. Rather than simply describing the content of the sources in order, the author uses transitions (like "similarly") and makes the relationship between the sources evident.

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.

summary table for synthesizing the literature

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.

synthesis matrix

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.

synthesizing the literature using themes

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?

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

Step 1 Understand the concept of a synthesis essay.

  • 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.

Step 2 Choose a topic suitable for a synthesis essay.

  • 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.

Step 3 Choose and read your sources carefully.

  • 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.

Step 4 Develop a thesis...

  • 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.

Step 5 Re-read your source material for items to support your thesis.

  • 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

Step 1 Outline the structure of your thesis.

  • 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.

Step 2 Use a more creative structure to present your thesis.

  • 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.

Step 3 Create an outline appropriate for a background or review synthesis essay.

  • 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

Step 1 Write your first draft according to your outline.

  • 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.

Step 2 Write in the third person.

  • 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

Step 1 Revise 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?

Step 2 Proofread your paper.

  • 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.

Step 3  Cite your...

  • 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.

Step 4 Title your essay.

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

How to Write a Synthesis Essay

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!

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?

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

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.

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
  • Analyzing the sources and outlining your response: 10 minutes
  • Drafting your response: 25 minutes
  • Reviewing and revising your response: 5 minutes

Before you turn in that paper, don’t forget to cite your sources in APA format , MLA format , or a style of your choice.

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.
