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.

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?

Literature Syntheis 101

How To Synthesise The Existing Research (With Examples)

By: Derek Jansen (MBA) | Expert Reviewer: Eunice Rautenbach (DTech) | August 2023

One of the most common mistakes that students make when writing a literature review is that they err on the side of describing the existing literature rather than providing a critical synthesis of it. In this post, we’ll unpack what exactly synthesis means and show you how to craft a strong literature synthesis using practical examples.

This post is based on our popular online course, Literature Review Bootcamp . In the course, we walk you through the full process of developing a literature review, step by step. If it’s your first time writing a literature review, you definitely want to use this link to get 50% off the course (limited-time offer).

Overview: Literature Synthesis

  • What exactly does “synthesis” mean?
  • Aspect 1: Agreement
  • Aspect 2: Disagreement
  • Aspect 3: Key theories
  • Aspect 4: Contexts
  • Aspect 5: Methodologies
  • Bringing it all together

What does “synthesis” actually mean?

As a starting point, let’s quickly define what exactly we mean when we use the term “synthesis” within the context of a literature review.

Simply put, literature synthesis means going beyond just describing what everyone has said and found. Instead, synthesis is about bringing together all the information from various sources to present a cohesive assessment of the current state of knowledge in relation to your study’s research aims and questions .

Put another way, a good synthesis tells the reader exactly where the current research is “at” in terms of the topic you’re interested in – specifically, what’s known , what’s not , and where there’s a need for more research .

So, how do you go about doing this?

Well, there’s no “one right way” when it comes to literature synthesis, but we’ve found that it’s particularly useful to ask yourself five key questions when you’re working on your literature review. Having done so,  you can then address them more articulately within your actual write up. So, let’s take a look at each of these questions.

Free Webinar: Literature Review 101

1. Points Of Agreement

The first question that you need to ask yourself is: “Overall, what things seem to be agreed upon by the vast majority of the literature?”

For example, if your research aim is to identify which factors contribute toward job satisfaction, you’ll need to identify which factors are broadly agreed upon and “settled” within the literature. Naturally, there may at times be some lone contrarian that has a radical viewpoint , but, provided that the vast majority of researchers are in agreement, you can put these random outliers to the side. That is, of course, unless your research aims to explore a contrarian viewpoint and there’s a clear justification for doing so. 

Identifying what’s broadly agreed upon is an essential starting point for synthesising the literature, because you generally don’t want (or need) to reinvent the wheel or run down a road investigating something that is already well established . So, addressing this question first lays a foundation of “settled” knowledge.

2. Points Of Disagreement

Related to the previous point, but on the other end of the spectrum, is the equally important question: “Where do the disagreements lie?” .

In other words, which things are not well agreed upon by current researchers? It’s important to clarify here that by disagreement, we don’t mean that researchers are (necessarily) fighting over it – just that there are relatively mixed findings within the empirical research , with no firm consensus amongst researchers.

This is a really important question to address as these “disagreements” will often set the stage for the research gap(s). In other words, they provide clues regarding potential opportunities for further research, which your study can then (hopefully) contribute toward filling. If you’re not familiar with the concept of a research gap, be sure to check out our explainer video covering exactly that .

3. Key Theories

The next question you need to ask yourself is: “Which key theories seem to be coming up repeatedly?” .

Within most research spaces, you’ll find that you keep running into a handful of key theories that are referred to over and over again. Apart from identifying these theories, you’ll also need to think about how they’re connected to each other. Specifically, you need to ask yourself:

  • Are they all covering the same ground or do they have different focal points  or underlying assumptions ?
  • Do some of them feed into each other and if so, is there an opportunity to integrate them into a more cohesive theory?
  • Do some of them pull in different directions ? If so, why might this be?
  • Do all of the theories define the key concepts and variables in the same way, or is there some disconnect? If so, what’s the impact of this ?

Simply put, you’ll need to pay careful attention to the key theories in your research area, as they will need to feature within your theoretical framework , which will form a critical component within your final literature review. This will set the foundation for your entire study, so it’s essential that you be critical in this area of your literature synthesis.

If this sounds a bit fluffy, don’t worry. We deep dive into the theoretical framework (as well as the conceptual framework) and look at practical examples in Literature Review Bootcamp . If you’d like to learn more, take advantage of our limited-time offer to get 60% off the standard price.

4. Contexts

The next question that you need to address in your literature synthesis is an important one, and that is: “Which contexts have (and have not) been covered by the existing research?” .

For example, sticking with our earlier hypothetical topic (factors that impact job satisfaction), you may find that most of the research has focused on white-collar , management-level staff within a primarily Western context, but little has been done on blue-collar workers in an Eastern context. Given the significant socio-cultural differences between these two groups, this is an important observation, as it could present a contextual research gap .

In practical terms, this means that you’ll need to carefully assess the context of each piece of literature that you’re engaging with, especially the empirical research (i.e., studies that have collected and analysed real-world data). Ideally, you should keep notes regarding the context of each study in some sort of catalogue or sheet, so that you can easily make sense of this before you start the writing phase. If you’d like, our free literature catalogue worksheet is a great tool for this task.

5. Methodological Approaches

Last but certainly not least, you need to ask yourself the question: “What types of research methodologies have (and haven’t) been used?”

For example, you might find that most studies have approached the topic using qualitative methods such as interviews and thematic analysis. Alternatively, you might find that most studies have used quantitative methods such as online surveys and statistical analysis.

But why does this matter?

Well, it can run in one of two potential directions . If you find that the vast majority of studies use a specific methodological approach, this could provide you with a firm foundation on which to base your own study’s methodology . In other words, you can use the methodologies of similar studies to inform (and justify) your own study’s research design .

On the other hand, you might argue that the lack of diverse methodological approaches presents a research gap , and therefore your study could contribute toward filling that gap by taking a different approach. For example, taking a qualitative approach to a research area that is typically approached quantitatively. Of course, if you’re going to go against the methodological grain, you’ll need to provide a strong justification for why your proposed approach makes sense. Nevertheless, it is something worth at least considering.

Regardless of which route you opt for, you need to pay careful attention to the methodologies used in the relevant studies and provide at least some discussion about this in your write-up. Again, it’s useful to keep track of this on some sort of spreadsheet or catalogue as you digest each article, so consider grabbing a copy of our free literature catalogue if you don’t have anything in place.

Looking at the methodologies of existing, similar studies will help you develop a strong research methodology for your own study.

Bringing It All Together

Alright, so we’ve looked at five important questions that you need to ask (and answer) to help you develop a strong synthesis within your literature review.  To recap, these are:

  • Which things are broadly agreed upon within the current research?
  • Which things are the subject of disagreement (or at least, present mixed findings)?
  • Which theories seem to be central to your research topic and how do they relate or compare to each other?
  • Which contexts have (and haven’t) been covered?
  • Which methodological approaches are most common?

Importantly, you’re not just asking yourself these questions for the sake of asking them – they’re not just a reflection exercise. You need to weave your answers to them into your actual literature review when you write it up. How exactly you do this will vary from project to project depending on the structure you opt for, but you’ll still need to address them within your literature review, whichever route you go.

The best approach is to spend some time actually writing out your answers to these questions, as opposed to just thinking about them in your head. Putting your thoughts onto paper really helps you flesh out your thinking . As you do this, don’t just write down the answers – instead, think about what they mean in terms of the research gap you’ll present , as well as the methodological approach you’ll take . Your literature synthesis needs to lay the groundwork for these two things, so it’s essential that you link all of it together in your mind, and of course, on paper.

When combining another author’s ideas with your own, we have talked about how using the can help make sure your points are being adequately argued (if you have not read our handout on the  evidence cycle,  check it out!). Synthesis takes assertions (statements that describe your claim), evidence (facts and proof from outside sources), and commentary (your connections to why the evidence supports your claim), and blends these processes together to make a cohesive paragraph.

In other words, synthesis encompasses several aspects:

  • It is the process of integrating support from more than one source for one idea/argument while also identifying how sources are related to each other and to your main idea.
  • It is an acknowledgment of how the source material from several sources address the same question/research topic.
  • It is the identification of how important factors (assumptions, interpretations of results, theories, hypothesis, speculations, etc.) relate between separate sources.

TIP: It’s a fruit smoothie!

Think of synthesis as a fruit smoothie that you are creating in your paper. You will have unique parts and flavors in your writing that you will need to blend together to make one tasty, unified drink!

Why Synthesis is Important

  • Synthesis integrates information from multiple sources, which shows that you have done the necessary research to engage with a topic more fully.
  • Research involves incorporating many sources to understand and/or answer a research question, and discovering these connections between the sources helps you better analyze and understand the conversations surrounding your topic.
  • Successful synthesis creates links between your ideas helping your paper “flow” and connect better.
  • Synthesis prevents your papers from looking like a list of copied and pasted sources from various authors.
  • Synthesis is a higher order process in writing—this is the area where you as a writer get to shine and show your audience your reasoning.

Types of Synthesis

Demonstrates how two or more sources agree with one another.

The collaborative nature of writing tutorials has been discussed by scholars like Andrea Lunsford (1991) and Stephen North (1984). In these essays, they explore the usefulness and the complexities of collaboration between tutors and students in writing center contexts.

Demonstrates how two or more sources support a main point in different ways.

While some scholars like Berlin (1987) have primarily placed their focus on the histories of large, famous universities, other scholars like Yahner and Murdick (1991) have found value in connecting their local histories to contrast or highlight trends found in bigger-name universities.

Accumulation

Demonstrates how one source builds on the idea of another.

Although North’s (1984) essay is fundamental to many writing centers today, Lunsford (1991) takes his ideas a step further by identifying different writing center models and also expanding North’s ideas on how writing centers can help students become better writers.

Demonstrates how one source discusses the effects of another source’s ideas.

While Healy (2001) notes the concerns of having primarily email appointments in writing centers, he also notes that constraints like funding, resources, and time affect how online resources are formed. For writing centers, email is the most economical and practical option for those wanting to offer online services but cannot dedicate the time or money to other online tutoring methods. As a result, in Neaderheiser and Wolfe’s (2009) reveals that of all the online options available in higher education, over 91% of institutions utilize online tutoring through email, meaning these constraints significantly affect the types of services writing centers offer.

Discussing Specific Source Ideas/Arguments

To debate with clarity and precision, you may need to incorporate a quote into your statement. Using can help you to thoroughly introduce your quotes so that they fit in to your paragraph and your argument. Remember that you need to use the to bridge between your ideas and outside source material.

Basics of Synthesis

As you incorporate published writing into your own writing, you should aim for synthesis of the material.

Synthesizing requires critical reading and thinking in order to compare different material, highlighting similarities, differences, and connections. When writers synthesize successfully, they present new ideas based on interpretations of other evidence or arguments. You can also think of synthesis as an extension of—or a more complicated form of—analysis. One main difference is that synthesis involves multiple sources, while analysis often focuses on one source.

Conceptually, it can be helpful to think about synthesis existing at both the local (or paragraph) level and the global (or paper) level.

Local Synthesis

Local synthesis occurs at the paragraph level when writers connect individual pieces of evidence from multiple sources to support a paragraph’s main idea and advance a paper’s thesis statement. A common example in academic writing is a scholarly paragraph that includes a main idea, evidence from multiple sources, and analysis of those multiple sources together.

Global Synthesis

Global synthesis occurs at the paper (or, sometimes, section) level when writers connect ideas across paragraphs or sections to create a new narrative whole. A literature review , which can either stand alone or be a section/chapter within a capstone, is a common example of a place where global synthesis is necessary. However, in almost all academic writing, global synthesis is created by and sometimes referred to as good cohesion and flow.

Synthesis in Literature Reviews

While any types of scholarly writing can include synthesis, it is most often discussed in the context of literature reviews. Visit our literature review pages for more information about synthesis in literature reviews.

How to Write a Synthesis Essay: Your Guide From Start to Finish

how to write synthesis in research paper

Today, we're swamped with information, like reading 174 newspapers every day. It comes from all over—news, social media, science, and more. This flood might make you feel overwhelmed and lost in a sea of facts and opinions. But being able to make sense of it all is crucial.

This guide isn't just about handling all that info; it's about using it to write awesome essays. We'll show you step by step how to pick a topic and organize your essay. Let's dive in and learn how to turn scattered facts into powerful essays that really stand out.

What Is a Synthesis Essay

The synthesis essay is a powerful tool in writing. It's not just about gathering facts but about connecting them to make a clear and strong argument.

Writing a synthesis essay allows you to dive deep into ideas. You have to find similarities between different sources—like articles, studies, or arguments—and use them to tell a convincing story.

In today's world, where we're bombarded with information, synthesis essays are more important than ever. They let us explore how different ideas fit together and help us express our thoughts on complex topics. Whether you're writing about literature, science, history, or current events, a synthesis essay shows off your ability to analyze and understand a topic from all angles. And if you're struggling with this task, just ask us to ' write paper for me ,' and we'll handle your assignment for you.

Explanatory vs. Argumentative Synthesis Essays

In synthesis writing, there are two main types: explanatory and argumentative. Understanding these categories is key because they shape how you approach your essay.

Explanatory:

An explanatory synthesis essay does just what it says—it explains. These essays aim to give a balanced view of a topic by gathering information from different sources and presenting it clearly. They don't try to persuade; instead, they focus on providing information and making things easier to understand. They're like comprehensive summaries, breaking down complex ideas for a broader audience. These essays rely heavily on facts and expert opinions, avoiding personal bias.

Argumentative:

On the flip side, argumentative synthesis essays are all about persuasion. Their main goal is to take a stance on an issue and convince the reader. They gather information from various sources not only to present different views but also to build a strong argument. Argumentative essays aim to sway the reader's opinion by using gathered information as evidence. These essays express opinions and use rhetorical strategies to persuade.

And if you're keen on knowing how to write an informative essay , we've got you covered on that, too!

Synthesis Essay Structure

To craft a strong synthesis essay, you need a solid foundation. Here's a structured approach to help you nail it:

Introductory Paragraph:

  • To kick things off, grab your reader's attention with a catchy hook or interesting fact. Give a bit of background info about your topic and the sources you'll be using, as it can help readers understand your topic better! Then, lay out your main argument in a clear thesis statement.

Body Paragraphs:

  • Each paragraph should focus on a different aspect of your topic or source. Start with a topic sentence that links back to your thesis. Introduce the source you're discussing and highlight its main points. Also, using quotes, paraphrases, or summaries from your sources can make your arguments stronger.

Synthesis :

  • This part is where your essay comes together. Look for common themes or differences among your sources. Use your analysis to build a strong argument. Don't forget to address any opposing viewpoints if they're relevant!

Conclusion :

  • Wrap things up by restating your thesis and summarizing your main points. Explain why your argument is important and what it means in the bigger picture. End with a thought-provoking statement to leave a lasting impression.

References :

  • Finally, don't forget to list all your sources properly using the right citation style, like MLA or APA. Do you know that different citation styles have different rules? So, make sure you follow the right one!

Choosing a Synthesis Essay Topic

Picking essay topics is just the beginning. To write a great synthesis essay, you need to carefully evaluate and connect different sources to build a strong argument or viewpoint. Here's a step-by-step infographic guide to help you choose the right synthesis essay topics wisely.

How to Write a Synthesis Essay with Easy Steps

Writing a synthesis essay is similar to a compare and contrast essay . It requires a methodical approach to blend information from different sources into a strong and persuasive argument. Here are some crucial steps and tips to help you along the way.

  • Clarify Your Purpose: First, decide if you're writing an explanatory or argumentative synthesis essay. This choice will set the tone and direction for your essay.
  • Source Selection and Analysis: Choose credible and relevant sources for your topic, balancing different types like articles, books, and websites. Analyze each source carefully, noting the main ideas and evidence presented.
  • Formulate a Strong Thesis Statement: Create a clear and concise thesis statement that guides your essay. It should express your main argument or perspective.
  • Structure Your Essay: Organize your essay with a clear synthesis essay outline, including an introduction, body paragraphs, and a conclusion. Each body paragraph should focus on a specific aspect of your topic.
  • Employ Effective Transition Sentences: Use transition sentences to connect your ideas and paragraphs smoothly, ensuring a cohesive flow in your essay.
  • Synthesize Information: Blend information from your sources within your paragraphs. Discuss how each source contributes to your thesis and highlight common themes or differences.
  • Avoid Simple Summarization: Don't just summarize your sources—analyze them critically and use them to build your argument.
  • Address Counterarguments (if applicable): Acknowledge opposing viewpoints and counter them with well-supported arguments, showing a deep understanding of the topic.
  • Craft a Resolute Conclusion: Summarize your main points and restate your thesis in the conclusion. Emphasize the importance of your argument or insights, and end with a thought-provoking statement or call to action. ‍
  • Revise and Proofread: Check your essay for clarity, coherence, and grammar mistakes. Ensure your citations are correct and follow the chosen citation style, like MLA or APA.

They usually fall into one of the popular styles: MLA, APA, or Chicago, each used in different academic fields.

synthesis essay format

1. MLA (Modern Language Association):

  • Uses in-text citations with the author's last name and page number.
  • Includes a 'Works Cited' page at the end listing all sources.
  • Focuses on the author and publication date.
  • Often used in humanities essays, research papers, and literary analyses.

2. APA (American Psychological Association):

  • Uses in-text citations with the author's last name and publication date in parentheses.

Synthesis Essay Example

Here are two examples of synthesis essays that demonstrate how to apply the synthesis process in real life. They explore interesting topics and offer practical guidance for mastering the art of writing this type of paper.

Synthesis Essay Tips

Crafting a strong synthesis essay requires careful planning and effective techniques. Here are five essential tips to help you write your best paper:

  • Diverse Source Selection : Choose a range of reliable sources that offer different viewpoints on your topic. Make sure they're recent and relevant to your subject.
  • Seamless Source Integration : Avoid just summarizing your sources. Instead, blend them into your essay by analyzing and comparing their ideas. Show how they connect to build your argument.
  • Balanced Tone : Maintain an impartial tone in your writing, even if you have personal opinions. Synthesis essays require objectivity, so they present different viewpoints without bias.
  • Focus on Synthesis : Remember, synthesis essays are about linking ideas, not just summarizing sources. Explore how your sources relate to each other to create a cohesive argument.
  • Address Counterarguments : Like in persuasive essays topics , acknowledge opposing viewpoints and explain why your perspective is stronger. This demonstrates your understanding of the topic and adds depth to your argument.

Concluding Thoughts

When writing a synthesis essay, it's essential to pick trustworthy sources, blend them effectively to build your argument and stay objective. Use smooth transitions, address counterarguments thoughtfully, and focus on analyzing rather than just summarizing. By following these steps, you'll create essays that inform, persuade, and engage your readers!

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 Matrix

A synthesis matrix helps you record the main points of each source and document how sources relate to each other.

After summarizing and evaluating your sources, arrange them in a matrix or use a citation manager to help you see how they relate to each other and apply to each of your themes or variables.  

By arranging your sources by theme or variable, you can see how your sources relate to each other, and can start thinking about how you weave them together to create a narrative.

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.

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.

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'

About This Article

Christopher Taylor, PhD

To write a synthesis essay, start by coming up with a thesis statement that you can support using all of the sources you've read for your essay. For example, your thesis statement could be "Texting has had a positive impact on the English language." Once you've got your thesis, go through your sources to find specific quotes, facts, and statistics that back up your claim. Structure your essay so it has an introduction that includes your thesis statement, a body that includes your arguments and evidence, and a conclusion that wraps everything up.

Synthesis is something you already do in your everyday life.  For example, if you are shopping for a new car, the research question you are trying to answer is, “Which car should I buy”?  You explore available models, prices, options, and consumer reviews, and you make comparisons.  For example:  Car X costs more than car Y but gets better mileage.  Or:  Reviewers A, B, and C all prefer Car X, but their praise is based primarily on design features that aren’t important to you.  It is this analysis across sources that moves you towards an answer to your question.

Early in an academic research project you are likely to find yourself making initial comparisons—for example, you may notice that Source A arrives at a conclusion very different from that of Source B—but the task of synthesis will become central to your work when you begin drafting your research paper or presentation. 

Remember, when you synthesize, you are not just compiling information.  You are organizing that information around a specific argument or question, and this work—your own intellectual work—is central to research writing.

Below are some questions that highlight ways in which the act of synthesizing brings together ideas and generates new knowledge. 

How do the sources speak to your specific argument or research question?

Your argument or research question is the main unifying element in your project.  Keep this in the forefront of your mind when you write about your sources.  Explain how, specifically, each source supports your central claim/s or suggests possible answers to your question.  For example:  Does the source provide essential background information or a definitional foundation for your argument or inquiry? Does it present numerical data that supports one of your points or helps you answer a question you have posed?  Does it present a theory that might be applied to some aspect of your project?  Does it present a recognized expert’s insights on your topic? 

How do the sources speak to each other? 

Sometimes you will find explicit dialogue between sources (for example, Source A refutes Source B by name), and sometimes you will need to bring your sources into dialogue (for example, Source A does not mention Source B, but you observe that the two are advancing similar or dissimilar arguments).  Attending to interrelationships among sources is at the heart of the task of synthesis.

Begin by asking:  What are the points of agreement?  Where are there disagreements?

But be aware that you are unlikely to find your sources in pure positions of “for” vs. “against.”  You are more likely to find agreement in some areas and disagreement in other areas.  You may also find agreement but for different reasons—such as different underlying values and priorities, or different methods of inquiry.

(See also Identifying a Conversation )

Where are there, or aren’t there, information gaps?

Where is the available information unreliable (for example, it might be difficult to trace back to primary sources), or limited, (for example, based on just a few case studies, or on just one geographical area), or difficult for non-specialists to access (for example, written in specialist language, or tucked away in a physical archive)? 

Does your inquiry contain sub-questions that may not at present be answerable, or that may not be answerable without additional primary research—for example, laboratory studies, direct observation, interviews with witnesses or participants, etc.?

Or, alternatively, is there a great deal of reliable, accessible information that addresses your question or speaks to your argument or inquiry? 

In considering these questions, you are engaged in synthesis: you are conducting an overview assessment of the field of available information and in this way generating composite knowledge.

Remember, synthesis is about pulling together information from a range of sources in order to answer a question or construct an argument. It is something you will be called upon to do in a wide variety of academic, professional, and personal contexts. Being able to dive into an ocean of information and surface with meaningful conclusions is an essential life skill.

📚 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.

The picture shows examples of synthesis usage in various spheres: biochemistry, physics, and sound creation.

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.

The picture explains the difference between a synthesis and a summary.

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.

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

The picture shows a synthesis essay outline: introduction, main body, and conclusion.

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.

Synthesis in Research: Home

What is synthesis?

Synthesizing information is the opposite of analyzing information. When you read an article or book, you have to pull out specific concepts from the larger document in order to understand it. This is analyzing.

When you synthesize information, you take specific concepts and consider them together to understand how they compare/contrast and how they relate to one another. Synthesis involves combining multiple elements to create a whole.

In regard to course assignments, the  elements  refer to the outside sources you've gathered to support the ideas you want to present. The  whole  then becomes your conclusion(s) about those sources.

how to write synthesis in research paper

How do I synthesize information?

Note: These steps offer a guideline, but do what works for you best.

  • This is where you really decide if you want to read specific materials
  • If you have gathered a substantial amount of literature and reading all of it would prove overwhelming, read the abstracts to get a better idea of the content, then select the materials that would best support your assignment
  • Describe and analyze the findings and/or the author's main ideas
  • What's the author's message?
  • What evidence do they use to support their message?
  • What does the author want a reader to understand?
  • What is the larger impact of the author's message?
  • Compare and contrast the main ideas and other pertinent information you found in each source
  • Evaluate the quality and significance of these main ideas
  • Interpret the main ideas in the context of your research question or assignment topic
  • This is the step where your synthesis of the information will lead to logical conclusions about that information
  • These conclusions should speak directly to your research question (i.e. your question should have an answer)

Synthesis and Making Connections for Strong Analysis

by acburton | Apr 25, 2024 | Resources for Students , Writing Resources

Russian nesting dolls image

If Russian Dolls Aren’t For You, Here Are a Few Other Ways to Think About Synthesis

‘Joining the Conversation’: When we perform synthesis in our writing and engage with making connections, we are joining a wider conversation. We are seeing what has already been said about the topic, seeking out what these many perspectives and viewpoints have in common and/or how they differ, and then interpreting these relationships to form our own input to the conversation. We must directly engage with our sources to draw insightful conclusions and share what we think as a result. ‘Building the Bridge’: Synthesis is building the bridge between your sources for the reader. To synthesize or make connections, we must figure out how we get from one source to the other. In other words, we cannot present our sources in isolation (this wouldn’t help create any new meaning). Instead, we need to build the bridge between source A and source B so that our readers can understand what the two, together, suggest about our understanding of a topic. Then, we build a bridge from this new understanding to source C and source D, and so on.

Start Synthesizing

So you want to synthesize information? To start, review the existing literature on your selected topic. When searching for resources, aim to collect a number from various authors, subjects, and settings to broaden your understanding of the material – giving yourself more information to consider in the next stage. Ultimately, you’ll want to find the main idea presented in each source, as well as how the author supports or argues against it, as well as why.

  • Compare and Contrast

Compare and contrast the main idea found in each source reviewed. What does each perspective have in common? What are their differences? Begin to consider how these sources  ‘fit together’ (or, in other words, build the bridge!). During this stage, you may find that some of your collected resources don’t have as much depth or go into as much detail as you’d like. That’s okay, but you’ll want to consider what effect this might have on your ability to draw a meaningful conclusion once synthesized with other source material.

  • Ask, What’s the Significance?

By evaluating the quality and significance of each source, you can begin to consider its relevance within the context of your research or in relation to your topic. How does the relationship of one source to another further your understanding of the topic you are focusing on? What is the larger impact of what is being said or argued?

  • Infer the Relationship and Draw Conclusions

By this point, you have gone through the existing literature surrounding your subject and compared/contrasted it, finding the main idea of each, as well as their intended purpose, possible criticisms, strengths, and weaknesses. Finally, you have related these ideas to your own research. Although you may have found that your sources agree or disagree on minor (or major) key details, it is the writer’s job to seek the relationship between these sources, put them in conversation together, and draw meaning through analysis. In some cases, you’ll be asked to offer your own perspective or argumentation. Consider, how might you add to the existing conversation?

Synthesis is all about meaningful connections, it is not summarizing sources side by side. Before you make larger claims about a topic, make sure you build those bridges between the sources you found through research. Nestle them together. Move beyond summary. Then, you can create an interesting and compelling argument. For additional help, make an appointment with the Writing Center!
