6.1: Writing from an outline
Learning Objectives
Learners will be able to…
- Integrate facts from the literature into scholarly writing
- Experiment with different approaches to integrating information that do not involve direct quotations from other authors
Congratulations! By now, you should have discovered, retrieved, evaluated, synthesized, and organized the information you need for your literature review. It’s now time to turn that stack of articles, papers, and notes into a literature review–it’s time to start writing!
The first step in research writing is outlining. In Chapter 4, we reviewed how to build a topical outline using quotations and facts from other authors. Use that outline (or one you write now) as a way to organize your thoughts.
Watch this video from Nicholas Cifuentes-Goodbody on Outlining. As he highlights, outlining is like building a mise en place before a meal–arranging your ingredients in an orderly way so you can create your masterpiece.
From quotations to original writing
Much like combining ingredients on a kitchen countertop, you will need to mix your ingredients together. That means you will not be relying extensively on quotations from other authors in your literature review. In moving from an outline to a literature review, the key intellectual move is relying on your own ideas about the literature, rather than quoting extensively from other sources.
Integrating ideas from other authors
Watch this video from Nicholas Cifuentes-Goodbody on using quotations in academic writing. In the video, he reviews a few different techniques to integrate quotations or ideas from other authors into your writing. All literature reviews use the ideas from other authors, but it’s important not to overuse others’ words. Your literature review is evaluated by your professor based on how well it shows you are able to make connections between different facts in the scientific literature. The examples in this section should highlight how to get other people’s words out of the way of your own. Use these strategies to diversify your writing and show your readers how your sources contributed to your work.
1. Make a claim without a quote
Example
Claim (Citation)
Some view cities as the storehouse of culture and creativity, and propose that urbanization is a consequence of the attractiveness of these social benefits (Mumford, 1961).
More information
Oftentimes you do not need to directly quote a source to convey its conclusions or arguments – and some disciplines discourage quoting directly! Rather you can paraphrase the main point of a paper in your own words and provide an in-text citation. A benefit of using this strategy is that you can offer support for a claim without using a whole paragraph to introduce and frame a quote. You should make sure that you fully understand the paper’s argument and that you are following university citation guidelines before attempting to paraphrase something from a paper.
2. Make a claim that is supported by two or more sources:
Example
Claim (Citation 1; Citation 2).
Reviews of this literature concede difficulty in making direct comparisons of emission levels across different sets of analysis (Bader and Bleischwitz, 2009; Kennedy et al., 2009; Ramaswami et al., 2012).
More information
Sometimes multiple sources support your claim, or there are two major publications that deserve credit for providing evidence on a topic. This is a perfect time to use multiple citations. You can cite two, three, or more sources in a single sentence!
Make a claim that has been supported in multiple contexts:
Context 1 (Citation), Context 2 (Citation), Context 3 (Citation).
Example:
These results are supported by more recent research on transportation energy consumption (Liddle, 2014), electricity consumption in buildings (Lariviere and Lafrance, 1999), and overall urban GHG emissions (Marcotullio et al., 2013b).
More information:
Use this citation strategy when you want to show that a body of research has found support for some claim across several different contexts. This can show the robustness of an effect or phenomenon and can give your claim some added validity
3. Quote important or unique terms
Example
Claim “Term” (Citation).
The spatial implications of this thinking are manifest in the “concentric ring model” of urban expansion and its variants (Harris and Ullman, 1945).
More information
While block or even whole-sentence citations are rare in most research papers in the science and social science disciplines, there is often a need to quote specific terms or phrases that were first coined by a certain source or that were well-explained in a specific paper.
4. Quoting definitions
Contextualize quote, “important word or phrase.”
Example:
Role conflict is defined as “A situation in which contradictory, competing, or incompatible expectations are placed on an individual by two or more roles held at the same time” (Open Sociology Dictionary, 2023); whereas, role strain is defined as “a situation caused by higher-than-expected demands placed on an individual performing a specific role that leads to difficulty or stress” (Open Sociology Dictionary, 2023). In our study, we hypothesize that caregivers who reenter higher education experience role conflict between school work, paid work, and care work. Further, we hypothesize that this conflict is greater in individuals who had experienced role strain in employment or caregiving prior to entering college.
More information
A direct quotation can bring attention to specific language in your source. When someone puts something perfectly, you can use a quotation to convey the identical meaning in your work. Definitions are an excellent example of when to use a quotation. In other cases, there may be quotations from important thinkers, clients or community members, and others whose specific wording is important.
I encourage you to use few, if any, direct quotations in your literature review. Personally, I think most students are scared of looking stupid and would rather use a good quotation than risk not getting it right. If you are a student who considers themselves a strong writer, this may not sound relevant to you. However, I’m willing to bet that there are many of your peers for whom this describes a particular bit of research anxiety.
When using quotations, make sure to only include the parts of the quotation that are necessary. You do not need to use quotation marks for statistics you use. And I encourage you to find ways to put others’ statistics in your sentences.
Why share information from other sources?
Now that you know some different sentence structures using APA citations, let’s examine the purpose behind why you are sharing information from another source. Cited evidence can serve a wide range of purposes in academic papers. These examples will give you an idea of the different ways that you can use citations in your paper.
1. Summarize your source
Example
The studies of Newman and Kenworthy (1989, 1999) demonstrate a negative relationship between population density and transportation fuel use.
More information
You will help your reader understand your points better if you summarize the key points of a study. Describe the strengths or weaknesses a specific source that has been pivotal in your field. Describe the source’s specific methodology, theory, or approach. Be sure to still include a citation. If you mention the name of the author in your text, you still need to provide the date of the study in a parenthetical citation.
2. Cite a method
Example
Despite the popularity of the WUP indicators, they have been routinely criticized because the methodology relies on local- and country-specific definitions of bounding urban areas, resulting in of ten incomparable and widely divergent definitions of the population, density thresholds, or administrative/political units designated (Satterthwaite, 2007).
More information
This is an easy way to give credit to a source that has provided some evidence for the validity of a method or questionnaire. Readers can reference your citation if they are interested in knowing more about the method and its standing in the current literature.
3. Compare sources
Example
Some evidence for this scaling relationship suggests that urban areas with larger population sizes have proportionally smaller energy infrastructures than smaller cities (Bettencourt et al., 2007; Fragkias et al., 2013). Other evidence suggests that GHG emissions may increase more than proportionally to population size, such that larger cities exhibit proportionally higher energy demand as they grow than do smaller cities (Marcotullio et al., 2013).
More information
This is one of the most important techniques for creating an effective literature review. This allows you and your readers to consider controversies and discrepancies among the current literature, revealing gaps in the literature or points of contention for further study.
The examples in this guide come from:
Marcotullio, P. J., Hughes, S., Sarzynski, A., Pincetl, S., Sanchez Peña, L., Romero-Lankao, P., Runfola, D. and Seto, K. C. (2014), Urbanization and the carbon cycle: Contributions from social science. Earth’s Future, 2: 496–514. doi:10.1002/2014EF000257
Avoiding plagiarism
The most difficult thing about avoiding plagiarism is that reading so much of other people’s ideas can make them seem like your own after a while. We recommend you work through this interactive activity on determining how and when to cite other authors.
Key Takeaways
- Research writing requires outlining, which helps you arrange your facts neatly before writing. It’s similar to arranging all of your ingredients before you start cooking.
- Eliminate quotations from your writing as much as possible. Your literature review needs to be your analysis of the literature, not just a summary of other people’s good ideas.
Exercises
- Experiment with the prompts in this chapter as you begin to write your research question.
6.2 Writing your literature review
Learning Objectives
Learners will be able to…
- Describe the components of a literature review
- Begin to write your literature review
- Identify the purpose of a problem statement
- Apply the components of a formal argument to your topic
- Use elements of formal writing style, including signposting and transitions
- Recognize commons errors in literature reviews
Writing about research is different than other types of writing. Research writing is not like a journal entry or opinion paper. The goal here is not to apply your research question to your life or growth as a practitioner. Research writing is about the provision and interpretation of facts. The tone should be objective and unbiased, and personal experiences and opinions are excluded. Particularly for students who are used to writing case notes, research writing can be a challenge. That’s why its important to normalize getting help! If your professor has not built in peer review, consider setting up a peer review group among your peers. You should also reach out to your academic advisor to see if there are writing services on your campus available to graduate students. No one should feel bad for needing help with something they haven’t done before, haven’t done in a while, or were never taught how to do.
If you’ve followed the steps in this chapter, you likely have an outline, summary table, and concept map from which you can begin the writing process. But what do you need to include in your literature review? We’ve mentioned it before, but to summarize, a literature review should:
- Introduce the topic and define its key terms.
- Establish the importance of the topic.
- Provide an overview of the important literature related to the concepts found in the research question.
- Identify gaps or controversies in the literature.
- Point out consistent findings across studies.
- Synthesize that which is known about a topic, rather than just provide a summary of the articles you read.
- Discuss possible implications and directions for future research.
Do you have enough facts and sources to accomplish these tasks? It’s a good time to consult your outlines and notes on each article you plan to include in your literature review. You may also want to consult with your professor on what is expected of you. If there is something you are missing, you may want to jump back to section 2.3 where we discussed how to search for literature. While you can always fill in material, there is the danger that you will start writing without really knowing what you are talking about or what you want to say. For example, if you don’t have a solid definition of your key concepts or a sense of how the literature has developed over time, it will be difficult to make coherent scholarly claims about your topic.
There is no magical point at which one is ready to write. As you consider whether you are ready, it may be useful to ask yourself these questions:
- How will my literature review be organized?
- What section headings will I be using?
- How do the various studies relate to each other?
- What contributions do they make to the field?
- Where are the gaps or limitations in existing research?
- And finally, but most importantly, how does my own research fit into what has already been done?
The problem statement
Scholarly works often begin with a problem statement, which serves two functions. First, it establishes why your topic is a social problem worth studying. Second, it pulls your reader into the literature review. Who would want to read about something unimportant?
A problem statement generally answers the following questions, though these are far from exhaustive:
- Why is this an important problem to study?
- How many people are affected by this problem?
- How does this problem impact other social issues relevant to social work?
- Why is your target population an important one to study?
A strong problem statement, like the rest of your literature review, should be filled with empirical results, theory, and arguments based on the extant literature. A research proposal differs significantly from other more reflective essays you’ve likely completed during your social work studies. If your topic were domestic violence in rural Appalachia, I’m sure you could come up with answers to the above questions without looking at a single source. However, the purpose of the literature review is not to test your intuition, personal experience, or empathy. Instead, research methods are about gaining specific and articulable knowledge to inform action. With a problem statement, you can take a “boring” topic like the color of rooms used in an inpatient psychiatric facility, transportation patterns in major cities, or the materials used to manufacture baby bottles, and help others see the topic as you see it—an important part of the social world that impacts social work practice.
The structure of a literature review
In general, the problem statement belongs at the beginning of the literature review. We usually advise students to spend no more than a paragraph or two for a problem statement. For the rest of your literature review, there is no set formula by which it needs to be organized. However, a literature review generally follows the format of any other essay—Introduction, Body, and Conclusion.
The introduction to the literature review contains a statement or statements about the overall topic. At a minimum, the introduction should define or identify the general topic, issue, or area of concern. You might consider presenting historical background, mentioning the results of a seminal study, and providing definitions of important terms. The introduction may also point to overall trends in what has been previously published on the topic or on conflicts in theory, methodology, evidence, conclusions, or gaps in research and scholarship. We also suggest putting in a few sentences that walk the reader through the rest of the literature review. Highlight your main arguments from the body of the literature review and preview your conclusion. An introduction should let the reader know what to expect from the rest of your review.
The body of your literature review is where you demonstrate your synthesis and analysis of the literature. Again, do not just summarize the literature. We would also caution against organizing your literature review by source—that is, one paragraph for source A, one paragraph for source B, etc. That structure will likely provide an adequate summary of the literature you’ve found, but it would give you almost no synthesis of the literature. That approach doesn’t tell your reader how to put those facts together, it doesn’t highlight points of agreement or contention, or how each study builds on the work of others. In short, it does not demonstrate critical thinking.
Organize your review by argument
Instead, use your outlines and notes as a guide what you have to say about the important topics you need to cover. Literature reviews are written from the perspective of an expert in that field. After an exhaustive literature review, you should feel as though you are able to make strong claims about what is true—so make them! There is no need to hide behind “I believe” or “I think.” Put your voice out in front, loud and proud! But make sure you have facts and sources that back up your claims.
I’ve used the term “argument” here in a specific way. An argument in writing means more than simply disagreeing with what someone else said, as this classic Monty Python sketch demonstrates. Toulman, Rieke, and Janik (1984) identify six elements of an argument:
- Claim: the thesis statement—what you are trying to prove
- Grounds: theoretical or empirical evidence that supports your claim
- Warrant: your reasoning (rule or principle) connecting the claim and its grounds
- Backing: further facts used to support or legitimize the warrant
- Qualifier: acknowledging that the argument may not be true for all cases
- Rebuttal: considering both sides (as cited in Burnette, 2012)[1]
Let’s walk through an example. If I were writing a literature review on a negative income tax, a policy in which people in poverty receive an unconditional cash stipend from the government each month equal to the federal poverty level, I would want to lay out the following:
- Claim: the negative income tax is superior to other forms of anti-poverty assistance.
- Grounds: data comparing negative income tax recipients to people receiving anti-poverty assistance in existing programs, theory supporting a negative income tax, data from evaluations of existing anti-poverty programs, etc.
- Warrant: cash-based programs like the negative income tax are superior to existing anti-poverty programs because they allow the recipient greater self-determination over how to spend their money.
- Backing: data demonstrating the beneficial effects of self-determination on people in poverty.
- Qualifier: the negative income tax does not provide taxpayers and voters with enough control to make sure people in poverty are not wasting financial assistance on frivolous items.
- Rebuttal: policy should be about empowering the oppressed, not protecting the taxpayer, and there are ways of addressing taxpayer spending concerns through policy design.
Like any effective argument, your literature review must have some kind of structure. For example, it might begin by describing a phenomenon in a general way along with several studies that provide some detail, then describing two or more competing theories of the phenomenon, and finally presenting a hypothesis to test one or more of the theories. Or, it might describe one phenomenon, then describe another that seems inconsistent with the first, then propose a theory that resolves the inconsistency, and finally present a hypothesis to test that theory. In applied research, it might describe a phenomenon or theory, then describe how that phenomenon or theory applies to some important real-world situation, and finally, may suggest a way to test whether it does, in fact, apply to that situation.
Use signposts
Another important issue is signposting. It may not be a term you are familiar with, but you are likely familiar with the concept. Signposting refers to the words used to identify the organization and structure of your literature review to your reader. The most basic form of signposting is using a topic sentence at the beginning of each paragraph. A topic sentence introduces the argument you plan to make in that paragraph. For example, you might start a paragraph stating, “There is strong disagreement in the literature as to whether psychedelic drugs cause people to develop psychotic disorders, or whether psychotic disorders cause people to use psychedelic drugs.” Within that paragraph, your reader would likely assume you will present evidence for both arguments. The concluding sentence of your paragraph should address the topic sentence, discussing how the facts and arguments from the paragraph you’ve written support a specific conclusion. To continue with our example, I might say, “There is likely a reciprocal effect in which both the use of psychedelic drugs worsens pre-psychotic symptoms and worsening psychosis increases the desire to use psychedelic drugs.”
Signposting also involves using headings and subheadings. Your literature review will use APA formatting, which means you need to follow their rules for bolding, capitalization, italicization, and indentation of headings. Headings help your reader understand the structure of your literature review. They can also help if the reader gets lost and needs to re-orient themselves within the document. We often tell our students to assume we know nothing (they don’t mind) and need to be shown exactly where they are addressing each part of the literature review. It’s like walking a small child around, telling them “First we’ll do this, then we’ll do that, and when we’re done, we’ll know this!”
Another way to use signposting is to open each paragraph with a sentence that links the topic of the paragraph with the one before it. Alternatively, one could end each paragraph with a sentence that links it with the next paragraph. For example, imagine we wanted to link a paragraph about barriers to accessing healthcare with one about the relationship between the patient and physician. We could use a transition sentence like this: “Even if patients overcome these barriers to accessing care, the physician-patient relationship can create new barriers to positive health outcomes.” A transition sentence like this builds a connection between two distinct topics. Transition sentences are also useful within paragraphs. They tell the reader how to consider one piece of information in light of previous information. Even simple transitional words like ‘however’ and ‘similarly’ can help demonstrate critical thinking and link each building block of your argument together.
Many beginning researchers have difficulty incorporating transitions into their writing. Let’s look at an example. Instead of beginning a sentence or paragraph by launching into a description of a study, such as “Williams (2004) found that…,” it is better to start by indicating something about why you are describing this particular study. Here are some simple examples:
- Another example of this phenomenon comes from the work of Williams (2004)…
- Williams (2004) offers one explanation of this phenomenon…
- An alternative perspective has been provided by Williams (2004)…
Now that we know to use signposts, the natural question is “What goes on the signposts?” First, it is important to start with an outline of the main points that you want to make, organized in the order you want to make them. The basic structure of your argument should then be apparent from the outline itself. Unfortunately, there is no formula we can give you that will work for everyone, but we can provide some general pointers on structuring your literature review.
The literature review tends to move from general to more specific ideas. You can build a review by identifying areas of consensus and areas of disagreement. You may choose to present historical studies—preferably seminal studies that are of significant importance—and close with the most recent research. Another approach is to start with the most distantly related facts and literature and then report on those most closely related to your research question. You could also compare and contrast valid approaches, features, characteristics, theories – that is, one approach, then a second approach, followed by a third approach.
Here are some additional tips for writing the body of your literature review:
- Start broad and then narrow down to more specific information.
- When appropriate, cite two or more sources for a single point, but avoid long strings of references for a single idea.
- Use quotes sparingly. Quotations for definitions are okay, but reserve quotes for when something is said so well you couldn’t possible phrase it differently. Never use quotes for statistics.
- Paraphrase when you need to relay the specific details within an article
- Include only the aspects of the study that are relevant to your literature review. Don’t insert extra facts about a study just to take up space.
- Avoid reflective, personal writing. It is traditional to avoid using first-person language (I, we, us, etc.).
- Avoid informal language like contractions, idioms, and rhetorical questions.
- Note any sections of your review that lack citations from the literature. Your arguments need to be based in empirical or theoretical facts. Do not approach this like a reflective journal entry.
- Point out consistent findings and emphasize stronger studies over weaker ones.
- Point out important strengths and weaknesses of research studies, as well as contradictions and inconsistent findings.
- Implications and suggestions for further research (where there are gaps in the current literature) should be specific.
The conclusion should summarize your literature review, discuss implications, and create a space for further research needed in this area. Your conclusion, like the rest of your literature review, should make a point. What are the important implications of your literature review? How do they inform the question you are trying to answer?
You should consult with your professor and the course syllabus about the final structure your literature review should take. Here is an example of one possible structure:
- Problem statement
- Establish the importance of the topic
- Number and type of people affected
- Seriousness of the impact
- Physical, psychological, economic, social, or spiritual consequences of the problem
- Argument 1
- Definitions of key terms
- Supporting evidence
- Common findings across studies, gaps in the literature
- Argument 2
- Definitions of key terms
- Supporting evidence
- Common findings across studies, gaps in the literature
- Argument 3
- Definitions of key terms
- Supporting evidence
- Common findings across studies, gaps in the literature
- Final paragraph
- Aim
- Research question(s) and hypothesis(es)
Editing your literature review
Literature reviews are more than a summary of the publications you find on a topic. As you have seen in this brief introduction, literature reviews represent a very specific type of research, analysis, and writing. We will explore these topics further in upcoming chapters. As you begin your literature review, here are some common errors to avoid:
- Accepting a researcher’s finding as valid without evaluating methodology and data
- Ignoring contrary findings and alternative interpretations
- Using findings that are not clearly related to your own study or using findings that are too general
- Dedicating insufficient time to literature searching
- Reporting statistical results from a single study, rather than synthesizing the results of multiple studies to provide a comprehensive view of the literature on a topic
- Relying too heavily on secondary sources
- Overusing quotations
- Not justifying arguments using specific facts or theories from the literature
For your literature review, remember that your goal is to construct an argument for the importance of your research question. As you start editing your literature review, make sure it is balanced. Accurately report common findings, areas where studies contradict each other, new theories or perspectives, and how studies cause us to reaffirm or challenge our understanding of your topic.
It is acceptable to argue that the balance of the research supports the existence of a phenomenon or is consistent with a theory (and that is usually the best that researchers in social work can hope for), but it is not acceptable to ignore contradictory evidence. A large part of what makes a research question interesting is uncertainty about its answer (University of Minnesota, 2016).[2]
In addition to subjectivity and bias, writer’s block can obstruct the completion of your literature review. Often times, writer’s block can stem from confusing the creating and editing parts of the writing process. Many writers often start by simply trying to type out what they want to say, regardless of how good it is. Author Anne Lamott (1995)[3] terms these “shitty first drafts,” and we all write them. They are a natural and important part of the writing process.
Even if you have a detailed outline from which to work, the words are not going to fall into place perfectly the first time you start writing. You should consider turning off the editing and critiquing part of your brain for a while and allow your thoughts to flow. Don’t worry about putting a correctly formatted internal citation (as long as you know which source you used there) when you first write. Just get the information out. Only after you’ve reached a natural stopping point might you go back and edit your draft for grammar, APA style, organization, flow, and more. Divorcing the writing and editing process can go a long way to addressing writer’s block—as can picking a topic about which you have something to say!
As you are editing, keep in mind these questions adapted from Green (2012):[4]
- Content: Have I clearly stated the main idea or purpose of the paper? Is the thesis or focus clearly presented and appropriate for the reader?
- Organization: How well is it structured? Is the organization spelled out and easy to follow for the reader ?
- Flow: Is there a logical flow from section to section, paragraph to paragraph, sentence to sentence? Are there transitions between and within paragraphs that link ideas together?
- Development: Have I validated the main idea with supporting material? Are supporting data sufficient? Does the conclusion match the introduction?
- Form: Are there any APA style issues, redundancy, problematic wording and terminology (always know the definition of any word you use!), flawed sentence constructions and selection, spelling, and punctuation?
APA Style
Social workers use the APA style guide to format and structure their literature reviews. Most students know APA style only as it relates to internal and external citations. If you are confused about them, consult this amazing APA style guide from the University of Texas-Arlington library. Your university’s library likely has resources they created to help you with APA style, and you can meet with a librarian or your professor to talk about formatting questions you have. Make sure you budget in a few hours at the end of each project to build a correctly formatted references page and check your internal citations. The highest quality online source of information on APA style is the APA style blog, where you can search questions and answers from the
Of course, APA style is about much more than knowing there is a period after “et al.” or citing the location a book was published. APA style is also about what the profession considers to be good writing. If you haven’t picked up an APA publication manual because you use citation generators, know that I did the same thing when I was in school. Purchasing the APA manual can help you with a common problem we hear about from students. Every professor (and every website about APA style) seems to have their own peculiar idea of “correct” APA style that you can, if needed, demonstrate is not accurate.
Key Takeaways
- A literature review is not a book report. Do not organize it by article, with one paragraph for each source in your references. Instead, organize it based on the key ideas and arguments.
- The problem statement draws the reader into your topic by highlighting the importance of the topic to social work and to society overall.
- Signposting is an important component of academic writing that helps your reader follow the structure of your argument and of your literature review.
- Transitions demonstrate critical thinking and help guide your reader through your arguments.
- Editing and writing are separate processes.
- Consult with an APA style guide or a librarian to help you format your paper.
