A paragraph is a group of related sentences that support one main idea. In general, paragraphs consist of three parts: the topic sentence, body sentences, and the concluding or the bridge sentence to the next paragraph or section. Paragraphs show where the subdivisions of a research paper begin and end and, thus, help the reader see the organization of the essay and grasp its main points.

Importance of Constructing Good Paragraphs

Paragraphs are the building blocks of papers . Without well-written paragraphs that flow logically from one idea to the next and that inform and help support in some meaningful way the central research problem being investigated, your paper will not be viewed as credible and, well, you'll probably receive a poor grade.

Here are some suggestions for troubleshooting common problems associated with developing paragraphs:

1.  The paragraph has no controlling idea . Imagine each paragraph as having three general layers of text. The core content is in the middle. It includes all the evidence you need to make the point. However, this evidence needs to be introduced by a topic sentence in some way or your readers don't know what to do with all the evidence you have given them. Therefore, the beginning of the paragraph explains the controlling idea of the paragraph. The last part of the paragraph tells the reader how the paragraph relates to the broader argument and often provides a transition to the next idea. Once you have mastered the use of topic sentences, you may decide that the topic sentence for a particular paragraph really should not be the first sentence of the paragraph. This is fine—the topic sentence can actually go at the beginning, middle, or end of a paragraph; what's important is that it is there to inform readers what the main idea of the paragraph is and how it relates back to the broader thesis of your paper.

2.  The paragraph has more than one controlling idea . This is the most common reason why a paragraph is too long. If a paragraph is more than a page long, it likely contains more than one controlling idea. In this case, consider eliminating sentences that relate to the second idea, with the thought that maybe they don't really inform and help support the central research problem, or split the paragraph into two or more paragraphs, each with only one controlling idea.

3.  Transitions are needed within the paragraph . You are probably familiar with the idea that transitions may be needed between paragraphs or sections in a paper. Sometimes they are also helpful within the body of a single paragraph. Within a paragraph, transitions are often single words or short phrases that help to establish relationships between ideas and to create a logical progression of those ideas in a paragraph. This is especially true within paragraphs that discuss multiple examples or discuss complex ideas, issues, or concepts.

Structure and Writing Style

I.  General Structure

Most paragraphs in an essay parallel the general three-part structure of each section of a research paper and, by extension, the overall research paper, with an introduction, a body that includes facts and analysis, and a conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating the meaning you intend to covey to the reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea. For long paragraphs, you may also want to include a bridge sentence that introduces the next paragraph or section of the paper. In some instances, the bridge sentence can be written in the form of a question. However, use this rhetorical device sparingly, otherwise, ending a lot of paragraphs with a question to lead into the next paragraph sounds cumbersome.

NOTE:   This general structure does not imply that you should not be creative in your writing. Arranging where each element goes in a paragraph can make a paper more engaging for the reader. However, do not be too creative in experimenting with the narrative flow of paragraphs. To do so may distract from the main arguments of your research and weaken the quality of your academic writing.

II.  Development and Organization

Before you can begin to determine what the composition of a particular paragraph will be, you must consider what is the most important idea that you are trying to convey to your reader. This is the "controlling idea," or the thesis statement from which you compose the remainder of the paragraph. In other words, your paragraphs should remind your reader that there is a recurrent relationship between your controlling idea and the information in each paragraph. The research problem functions like a seed from which your paper, and your ideas, will grow. The whole process of paragraph development is an organic one—a natural progression from a seed idea to a full-blown research study where there are direct, familial relationships in the paper between all of  your controlling ideas and the paragraphs which derive from them. The decision about what to put into your paragraphs begins with brainstorming about how you want to pursue the research problem . There are many techniques for brainstorming but, whichever one you choose, this stage of paragraph development cannot be skipped because it lays a foundation for developing a set of paragraphs [representing a section of your paper] that describes a specific element of your overall analysis. Each section is described further in this writing guide. Given these factors, every paragraph in a paper should be :

• Unified —All of the sentences in a single paragraph should be related to a single controlling idea [often expressed in the topic sentence of the paragraph].
• Clearly related to the research problem —The sentences should all refer to the central idea, or the thesis, of the paper.
• Coherent —The sentences should be arranged in a logical manner and should follow a definite plan for development.
• Well-developed —Every idea discussed in the paragraph should be adequately explained and supported through evidence and details that work together to explain the paragraph's controlling idea.

There are many different ways you can organize a paragraph . However, the organization you choose will depend on the controlling idea of the paragraph. Ways to organize a paragraph in academic writing include:

• Narrative : Tell a story. Go chronologically, from start to finish.
• Descriptive : Provide specific details about what something looks or feels like. Organize spatially, in order of appearance, or by topic.
• Process : Explain step by step how something works. Perhaps follow a sequence—first, second, third.
• Classification : Separate into groups or explain the various parts of a topic.
• Illustrative : Give examples and explain how those examples prove your point.

Writing Tip

Coherence of Ideas is What Matters, Not Length!

Do not think of developing paragraphs in terms of their length. Length and appearance do not determine whether a part in your paper is a paragraph. It is the unity and coherence of ideas represented in a sentence or among sentences that constitutes to a good paragraph.

Paragraph Development

Writers use words to compose sentences that develop ideas. A group of related sentences that develops a particular idea is organized in a unit called a paragraph. Understanding the basic concept of “paragraph” is easy enough, but applying that understanding—that is, writing strong, focused paragraphs—can pose challenges for writers of all levels of accomplishment. The discussion that follows will help you understand effective paragraphing and reinforce good writing habits. Keep in mind that writing is a process, and producing good writing, paragraph by paragraph, takes time. Learning to write effective paragraphs will help you communicate ideas clearly to an audience and help you achieve the purpose of the writing.

THE PURPOSE OF THE PARAGRAPH

Paragraphs are the basic units of a piece of writing. Whether informative, persuasive, expository/explanatory, or another mode of writing, paragraphs express the beginning, middle, and end of a discussion in the form of an introduction, body, and conclusion. Each of these parts can be one or more paragraphs long, and the paragraphs in each part have a different purpose. The focus of this tutorial is on body paragraphs. The purpose of body paragraphs is twofold: 1) body paragraphs work together to develop a discussion about a topic within the scope of the thesis or main idea about that topic, and 2) each body paragraph works individually to develop one point of the discussion with supporting details and language that connects the paragraph to the rest of the paper.

THE QUALITIES OF AN EFFECTIVE PARAGRAPH

Unity, Coherence, and Development

An effective paragraph will have unity, coherence, and development. Unity means that each sentence provides information that relates to the established focus of the paragraph. Coherence means each sentence logically leads to the next sentence, and the writer has provided transitions and guidewords to make the movement fluid for the reader and the different ideas come together cohesively. Lastly, development refers to sustaining and building the discussion by providing enough supporting details that the point of the paragraph is clearly communicated to an audience. While paragraph length can vary, effective paragraphs contain enough substantive content that readers do not have lingering questions.

Example Paragraph

One major contributor to the opioid epidemic has been the aggressive marketing of prescription painkillers by pharmaceutical manufacturers. Perez-Pena (2017) concluded that while the healthcare industry was attempting to effectively and efficiently treat patients with chronic pain, pharmaceutical companies were providing funding to prominent doctors, medical societies, and patient advocacy groups in order to win support for a particular drug’s adoption and usage. In fact, pharmaceutical companies continue to spend millions on promotional activities and materials that deny or trivialize any risks of opioid use while at the same time overstating each drug’s benefit (Perez-Pina, 2017). Although aggressive marketing by pharmaceutical companies has played a large role in opioid addiction, patients also play a role in the problem when they take advantage of holes in the healthcare provider system in order to remedy their addiction.

Perez-Pina, R. (2017, May 31). Ohio sues drug makers, saying they aided opioid epidemic. The New York Times . https://www.nytimes.com/2017/05/31/us/ohio-sues-pharmaceuticaldrug-opioid-epidemic-mike-dewine.html?_r=1

The example paragraph is unified on one topic: the opioid epidemic. It is cohesive; the ideas move from fact to evidence to example and include guiding words such as “one,” “while,” “in order to,” “in fact,” and “although,” which lead the reader from one sentence to the next. The paragraph is well-developed as it sustains discussion on the opioid epidemic and builds it with a new point about a contributing factor, which is presented with evidence from research and supporting details. It also uses language (e.g. “although”) that connects the paragraph topic, the role that pharmaceutical companies play, to the topic that will be discussed in the next paragraph, the role that patients play.

CONSIDERATIONS FOR WRITING AN EFFECTIVE PARAGRAPH

Limit the Focus to One Distinct Idea

The sentences in a paragraph work together to develop one distinct idea by sharing the same focus. One way that writers establish this focus is with a topic sentence at the beginning of the paragraph. The topic sentence not only expresses the topic of discussion for the paragraph but also asserts a controlling idea that limits the focus of that topic. To create this limited focus, writers provide facts, opinions, definitions, examples, anecdotes, and descriptions, for example, support or explain the controlling idea.

Develop Paragraphs With the Audience and Purpose in Mind

The information given in the paragraph will also depend on the audience and purpose of the writing. To develop a paragraph with the audience in mind, the writer needs to consider what the audience already knows. Discussions are generally developed by adding new information to known information. The same topic would be discussed differently to an audience that does not know anything about the topic versus an audience who are already very familiar with it. The writer must also consider the purpose of the writing. An informative paragraph, for example, seeks to enlighten or educate the reader about the topic whereas a persuasive paragraph seeks to change the reader’s mind or behavior through the discussion of the topic.

Critics have argued that technology will dehumanize education; in fact, technology can actually personalize education. For example, once a print textbook is adopted, schools will stay with the curriculum until the next textbook adoption cycle. However, as Minnesota’s Byron Independent School District (ISD) realized when they designed their own online curriculum, teachers can adapt an online curriculum as needed to individually personalize a student’s educational experience. For example, Byron’s teachers made real-time adjustments to a particular math unit if a particular student was struggling to master an intended learning objective (Fulton, 2013). The Byron ISD experiment suggested technology, combined with a thoughtful pedagogy, can have a lasting, personal and positive impact on student learning.

Fulton, K. (2013, September 1). Byron’s flipped classrooms. Education Digest , 79(1), 22-26. https://search.proquest.com/openview/49d7ee537168e132960671e4bef70582/1.pdf?pqorigsite=gscholar&cbl=25066

The example paragraph is limited in focus on one idea about the topic—that technology provides opportunities to personalize education. Each sentence works to support this idea in the form of facts, examples, and anecdotes. The paragraph is also tailored to a specific audience and purpose. The writer begins with an opposing viewpoint to appeal to readers who may be critical of educational technology. The purpose of this paragraph is to persuade, so by presenting the opposing viewpoint then counterarguing it with research-based examples, the reader is more likely to see the writer’s viewpoint as logical and change their own opinion about the topic.

Use Various Rhetorical Modes for Developing and Organizing Paragraphs

Rhetorical modes refer to the patterns of development available to the writer. In other words, modes are the particular manner in which writers develop their thoughts, and quite typically the mode comes to us naturally depending on what we are trying to accomplish. If someone is talking to an auto mechanic about a problem with their car, they are describing. If a person is telling a story about their seven-year-old daughter, they are narrating. If one is talking about the types of books they like to read, they use examples. Whatever a person is trying to convey, they will do so with one or more patterns of development or rhetorical modes.

Types of modes include description, narration, comparison and contrast, example, definition, cause and effect, analogy, and analysis. Usually, the focus of the paragraph lends itself to the use of one primary mode, but even so, most paragraphs utilize more than one pattern of development. For example, if a student is taking a United States history course, they may be asked to compare and contrast the South before and after the Civil War. While the predominant rhetorical mode used in paragraphs will be comparison and contrast, the student will also probably use examples, include description, and offer analysis as you compare the old South to the new South.

Rhetorical modes help writers think about their topic and organize their ideas. These rhetorical modes also show writers the options available to them when composing paragraphs.

When to Begin a New Paragraph

Paragraph length is dictated first by content and purpose. A new paragraph signals a pause in thought and a change in topic, directing readers to anticipate what is to follow or allowing them a moment to digest the material in the preceding paragraph. Reasons to begin a new paragraph include

• beginning a new idea,
• emphasizing a particular point,
• changing speakers in dialogue,
• allowing readers to pause, and
• breaking up lengthy text, usually moving to a subtopic.

Transitions and Signal Words

A paragraph needs to be developed in a logical manner, and readers need to be guided through that development. Writers need to help readers by using transitional expressions and other appropriate words to guide them through the development of the paragraph. Transitional expressions function like glue—they hold a piece of writing together and give it order.

Paragraph Length

Long paragraphs of as much as a page or more often lack a well-defined focus. They do not allow readers an opportunity to assimilate one point before another is made. Long paragraphs can be divided and reorganized into two or more focused paragraphs.

By contrast, short paragraphs can seem choppy and undeveloped. They often leave the reader craving more information. The writer must think carefully of the needs of their audience and the purpose for the writing, and develop each point accordingly. For example, a paper with a persuasive purpose, written for an audience that does not share the writer’s view may need more development in each paragraph in order to present a convincing case. Depending on the audience and purpose, a writer may need to include more or less information. Ideally, paragraph lengths should invite readers in, neither seeming too daunting to read through nor appearing incomplete.

PIE METHOD OF PARAGRAPH DEVELOPMENT

One good way to go about developing paragraphs is to use the PIE method: The writer makes a strong point as expressed in the topic sentence; illustrates the point with supporting details and evidence; then explains how the evidence supports the point of the paragraph and relates to the thesis. The bold and italic formatting in the following example shows the PIE method at work:

P – Point

I – Illustrate

E – Explain

Despite preservation efforts, barns are in jeopardy, a reflection not only of economics but also of the fading family farm. To make matters worse, razing an old barn is often easier than saving it. Many people who own an unused barn are reluctant to spend money on keeping the building standing, and if the barn is already in rough shape, they usually neglect it until it falls down or is taken down. Preservationists say that in the majority of cases, ailing barns simply need to be stabilized by replacing the sills around the perimeter of the structure. But even this is too costly for a structure that barn owners consider functionally obsolete. Despite using them as big garages, barns tend to be taken down rather than repaired. Even carpenters who make a livelihood in construction lack the skills and equipment required for barn preservation.

Take-Aways for Writing an Effective Paragraph

• Focus limited to one distinct idea
• Paragraphs developed with audience and purpose in mind
• Various rhetorical modes considered for developing and organizing paragraphs
• Transitions and guidewords connecting parts
• Content developed and organized by PIE

When Revising Paragraphs, Consider the Following Questions

• What is the topic and controlling idea?
• What should readers understand after reading the paragraph?
• Is the topic sentence clear and limited in focus?
• Are all of the supporting details unified on the controlling idea?
• Will readers understand the relationship of the supporting details to the point of the paragraph and the larger point of the essay?
• Is the content organized in a logical, easy-to-understand manner?
• Is the development sufficient for the audience and purpose?
• Does anything need to be added or deleted?

9.2 Writing Body Paragraphs

Learning objectives.

• Select primary support related to your thesis.
• Support your topic sentences.

If your thesis gives the reader a roadmap to your essay, then body paragraphs should closely follow that map. The reader should be able to predict what follows your introductory paragraph by simply reading the thesis statement.

The body paragraphs present the evidence you have gathered to confirm your thesis. Before you begin to support your thesis in the body, you must find information from a variety of sources that support and give credit to what you are trying to prove.

Select Primary Support for Your Thesis

Without primary support, your argument is not likely to be convincing. Primary support can be described as the major points you choose to expand on your thesis. It is the most important information you select to argue for your point of view. Each point you choose will be incorporated into the topic sentence for each body paragraph you write. Your primary supporting points are further supported by supporting details within the paragraphs.

Remember that a worthy argument is backed by examples. In order to construct a valid argument, good writers conduct lots of background research and take careful notes. They also talk to people knowledgeable about a topic in order to understand its implications before writing about it.

Identify the Characteristics of Good Primary Support

In order to fulfill the requirements of good primary support, the information you choose must meet the following standards:

• Be specific. The main points you make about your thesis and the examples you use to expand on those points need to be specific. Use specific examples to provide the evidence and to build upon your general ideas. These types of examples give your reader something narrow to focus on, and if used properly, they leave little doubt about your claim. General examples, while they convey the necessary information, are not nearly as compelling or useful in writing because they are too obvious and typical.
• Be relevant to the thesis. Primary support is considered strong when it relates directly to the thesis. Primary support should show, explain, or prove your main argument without delving into irrelevant details. When faced with lots of information that could be used to prove your thesis, you may think you need to include it all in your body paragraphs. But effective writers resist the temptation to lose focus. Choose your examples wisely by making sure they directly connect to your thesis.
• Be detailed. Remember that your thesis, while specific, should not be very detailed. The body paragraphs are where you develop the discussion that a thorough essay requires. Using detailed support shows readers that you have considered all the facts and chosen only the most precise details to enhance your point of view.

Prewrite to Identify Primary Supporting Points for a Thesis Statement

Recall that when you prewrite you essentially make a list of examples or reasons why you support your stance. Stemming from each point, you further provide details to support those reasons. After prewriting, you are then able to look back at the information and choose the most compelling pieces you will use in your body paragraphs.

Choose one of the following working thesis statements. On a separate sheet of paper, write for at least five minutes using one of the prewriting techniques you learned in Chapter 8 “The Writing Process: How Do I Begin?” .

• Unleashed dogs on city streets are a dangerous nuisance.
• Students cheat for many different reasons.
• Drug use among teens and young adults is a problem.
• The most important change that should occur at my college or university is ____________________________________________.

Select the Most Effective Primary Supporting Points for a Thesis Statement

After you have prewritten about your working thesis statement, you may have generated a lot of information, which may be edited out later. Remember that your primary support must be relevant to your thesis. Remind yourself of your main argument, and delete any ideas that do not directly relate to it. Omitting unrelated ideas ensures that you will use only the most convincing information in your body paragraphs. Choose at least three of only the most compelling points. These will serve as the topic sentences for your body paragraphs.

Refer to the previous exercise and select three of your most compelling reasons to support the thesis statement. Remember that the points you choose must be specific and relevant to the thesis. The statements you choose will be your primary support points, and you will later incorporate them into the topic sentences for the body paragraphs.

Collaboration

Please share with a classmate and compare your answers.

When you support your thesis, you are revealing evidence. Evidence includes anything that can help support your stance. The following are the kinds of evidence you will encounter as you conduct your research:

• Facts. Facts are the best kind of evidence to use because they often cannot be disputed. They can support your stance by providing background information on or a solid foundation for your point of view. However, some facts may still need explanation. For example, the sentence “The most populated state in the United States is California” is a pure fact, but it may require some explanation to make it relevant to your specific argument.
• Judgments. Judgments are conclusions drawn from the given facts. Judgments are more credible than opinions because they are founded upon careful reasoning and examination of a topic.
• Testimony. Testimony consists of direct quotations from either an eyewitness or an expert witness. An eyewitness is someone who has direct experience with a subject; he adds authenticity to an argument based on facts. An expert witness is a person who has extensive experience with a topic. This person studies the facts and provides commentary based on either facts or judgments, or both. An expert witness adds authority and credibility to an argument.
• Personal observation. Personal observation is similar to testimony, but personal observation consists of your testimony. It reflects what you know to be true because you have experiences and have formed either opinions or judgments about them. For instance, if you are one of five children and your thesis states that being part of a large family is beneficial to a child’s social development, you could use your own experience to support your thesis.

Writing at Work

In any job where you devise a plan, you will need to support the steps that you lay out. This is an area in which you would incorporate primary support into your writing. Choosing only the most specific and relevant information to expand upon the steps will ensure that your plan appears well-thought-out and precise.

You can consult a vast pool of resources to gather support for your stance. Citing relevant information from reliable sources ensures that your reader will take you seriously and consider your assertions. Use any of the following sources for your essay: newspapers or news organization websites, magazines, encyclopedias, and scholarly journals, which are periodicals that address topics in a specialized field.

Choose Supporting Topic Sentences

Each body paragraph contains a topic sentence that states one aspect of your thesis and then expands upon it. Like the thesis statement, each topic sentence should be specific and supported by concrete details, facts, or explanations.

Each body paragraph should comprise the following elements.

topic sentence + supporting details (examples, reasons, or arguments)

As you read in Chapter 8 “The Writing Process: How Do I Begin?” , topic sentences indicate the location and main points of the basic arguments of your essay. These sentences are vital to writing your body paragraphs because they always refer back to and support your thesis statement. Topic sentences are linked to the ideas you have introduced in your thesis, thus reminding readers what your essay is about. A paragraph without a clearly identified topic sentence may be unclear and scattered, just like an essay without a thesis statement.

Unless your teacher instructs otherwise, you should include at least three body paragraphs in your essay. A five-paragraph essay, including the introduction and conclusion, is commonly the standard for exams and essay assignments.

Consider the following the thesis statement:

Author J.D. Salinger relied primarily on his personal life and belief system as the foundation for the themes in the majority of his works.

The following topic sentence is a primary support point for the thesis. The topic sentence states exactly what the controlling idea of the paragraph is. Later, you will see the writer immediately provide support for the sentence.

Salinger, a World War II veteran, suffered from posttraumatic stress disorder, a disorder that influenced themes in many of his works.

In Note 9.19 “Exercise 2” , you chose three of your most convincing points to support the thesis statement you selected from the list. Take each point and incorporate it into a topic sentence for each body paragraph.

Supporting point 1: ____________________________________________

Topic sentence: ____________________________________________

Supporting point 2: ____________________________________________

Supporting point 3: ____________________________________________

Draft Supporting Detail Sentences for Each Primary Support Sentence

After deciding which primary support points you will use as your topic sentences, you must add details to clarify and demonstrate each of those points. These supporting details provide examples, facts, or evidence that support the topic sentence.

The writer drafts possible supporting detail sentences for each primary support sentence based on the thesis statement:

Thesis statement: Unleashed dogs on city streets are a dangerous nuisance.

Supporting point 1: Dogs can scare cyclists and pedestrians.

Supporting details:

• Cyclists are forced to zigzag on the road.
• School children panic and turn wildly on their bikes.
• People who are walking at night freeze in fear.

Supporting point 2:

Loose dogs are traffic hazards.

• Dogs in the street make people swerve their cars.
• To avoid dogs, drivers run into other cars or pedestrians.
• Children coaxing dogs across busy streets create danger.

Supporting point 3: Unleashed dogs damage gardens.

• They step on flowers and vegetables.
• They destroy hedges by urinating on them.
• They mess up lawns by digging holes.

The following paragraph contains supporting detail sentences for the primary support sentence (the topic sentence), which is underlined.

Salinger, a World War II veteran, suffered from posttraumatic stress disorder, a disorder that influenced the themes in many of his works. He did not hide his mental anguish over the horrors of war and once told his daughter, “You never really get the smell of burning flesh out of your nose, no matter how long you live.” His short story “A Perfect Day for a Bananafish” details a day in the life of a WWII veteran who was recently released from an army hospital for psychiatric problems. The man acts questionably with a little girl he meets on the beach before he returns to his hotel room and commits suicide. Another short story, “For Esmé – with Love and Squalor,” is narrated by a traumatized soldier who sparks an unusual relationship with a young girl he meets before he departs to partake in D-Day. Finally, in Salinger’s only novel, The Catcher in the Rye , he continues with the theme of posttraumatic stress, though not directly related to war. From a rest home for the mentally ill, sixteen-year-old Holden Caulfield narrates the story of his nervous breakdown following the death of his younger brother.

Using the three topic sentences you composed for the thesis statement in Note 9.18 “Exercise 1” , draft at least three supporting details for each point.

Thesis statement: ____________________________________________

Primary supporting point 1: ____________________________________________

Supporting details: ____________________________________________

Primary supporting point 2: ____________________________________________

Primary supporting point 3: ____________________________________________

You have the option of writing your topic sentences in one of three ways. You can state it at the beginning of the body paragraph, or at the end of the paragraph, or you do not have to write it at all. This is called an implied topic sentence. An implied topic sentence lets readers form the main idea for themselves. For beginning writers, it is best to not use implied topic sentences because it makes it harder to focus your writing. Your instructor may also want to clearly identify the sentences that support your thesis. For more information on the placement of thesis statements and implied topic statements, see Chapter 8 “The Writing Process: How Do I Begin?” .

Print out the first draft of your essay and use a highlighter to mark your topic sentences in the body paragraphs. Make sure they are clearly stated and accurately present your paragraphs, as well as accurately reflect your thesis. If your topic sentence contains information that does not exist in the rest of the paragraph, rewrite it to more accurately match the rest of the paragraph.

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

• Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
• Makes a promise to the reader about the scope, purpose, and direction of your paper.
• Is focused and specific enough to be “proven” within the boundaries of your paper.
• Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
• Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

• Franco first tried to negotiate with the Axis
• Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.

• The simile compares Simoisius to a tree, which is a peaceful, natural image.
• The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

• This paper will look at modern language to see if it reflects male dominance or female oppression.
• I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

• nature = peaceful
• war matériel = violent (competes with 1?)
• need for time and space to mourn the dead
• war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

• although most readers of _______ have argued that _______, closer examination shows that _______.
• _______ uses _______ and _____ to prove that ________.
• phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

• Ask if your draft thesis addresses the assignment
• Question each part of your draft thesis
• Clarify vague phrases and assertions
• Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

• Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.

Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.

Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.

While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.

While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

• Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
• As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
• Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
• Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

The Paragraph Body: Supporting Your Ideas

Whether the drafting of a paragraph begins with a main idea or whether that idea surfaces in the revision process, once you have that main idea, you’ll want to make sure that the idea has enough support. The job of the paragraph body is to develop and support the topic. Here’s one way that you might think about it:

• Topic sentence : what is the main claim of your paragraph; what is the most important idea that you want your readers to take away from this paragraph?
• Support in the form of evidence : how can you prove that your claim or idea is true (or important, or noteworthy, or relevant)?
• Support in the form of analysis or evaluation : what discussion can you provide that helps your readers see the connection between the evidence and your claim?
• Transition : how can you help your readers move from the idea you’re currently discussing to the next idea presented? (For more specific discussion about transitions, see the following section on “ Developing Relationships between Ideas ”).

For more on methods of development  that can help you to develop and organize your ideas within paragraphs, see “Patterns of Organization and Methods of Development” later in this section of this text.

Types of support might include

• Statistics.
• Quotations.

Now that we have a good idea what it means to develop support for the main ideas of your paragraphs, let’s talk about how to make sure that those supporting details are solid and convincing.

Good vs. Weak Support

What questions will your readers have? What will they need to know? What makes for good supporting details? Why might readers consider some evidence to be weak?

If you’re already developing paragraphs, it’s likely that you already have a plan for your essay, at least at the most basic level. You know what your topic is, you might have a working thesis, and you probably have at least a couple of supporting ideas in mind that will further develop and support your thesis.

So imagine you’re developing a paragraph on one of these supporting ideas and you need to make sure that the support that you develop for this idea is solid. Considering some of the points about understanding and appealing to your audience (from the Audience and Purpose and the Prewriting sections of this text) can also be helpful in determining what your readers will consider good support and what they’ll consider to be weak. Here are some tips on what to strive for and what to avoid when it comes to supporting details.

Breaking, Combining, or Beginning New Paragraphs

Like sentence length, paragraph length varies. There is no single ideal length for “the perfect paragraph.”  There are some general guidelines, however. Some writing handbooks or resources suggest that a paragraph should be at least three or four sentences; others suggest that 100 to 200 words is a good target to shoot for. In academic writing, paragraphs tend to be longer, while in less formal or less complex writing, such as in a newspaper, paragraphs tend to be much shorter. Two-thirds to three-fourths of a page is usually a good target length for paragraphs at your current level of college writing. If your readers can’t see a paragraph break on the page, they might wonder if the paragraph is ever going to end or they might lose interest.

The most important thing to keep in mind here is that the amount of space needed to develop one idea will likely be different than the amount of space needed to develop another. So when is a paragraph complete? The answer is, when it’s fully developed. The guidelines above for providing good support should help.

Some signals that it’s time to end a paragraph and start a new one include that

• You’re ready to begin developing a new idea.
• You want to emphasize a point by setting it apart.
• You’re getting ready to continue discussing the same idea but in a different way (e.g. shifting from comparison to contrast).
• You notice that your current paragraph is getting too long (more than three-fourths of a page or so), and you think your writers will need a visual break.

Some signals that you may want to combine paragraphs include that

• You notice that some of your paragraphs appear to be short and choppy.
• You have multiple paragraphs on the same topic.
• You have undeveloped material that needs to be united under a clear topic.

Finally, paragraph number is a lot like paragraph length. You may have been asked in the past to write a five-paragraph essay. There’s nothing inherently wrong with a five-paragraph essay, but just like sentence length and paragraph length, the number of paragraphs in an essay depends upon what’s needed to get the job done. There’s really no way to know that until you start writing. So try not to worry too much about the proper length and number of things. Just start writing and see where the essay and the paragraphs take you. There will be plenty of time to sort out the organization in the revision process. You’re not trying to fit pegs into holes here. You’re letting your ideas unfold. Give yourself—and them—the space to let that happen.

Tool in School: Quizlet

• Posted May 22, 2018
• By Lory Hough

When 15-year-old Andrew Sutherland created a software program in 2005 to help him study 111 French terms for a test on animals, little did he imagine that the program would eventually become one of the fastest-growing free education tools, with 30 million monthly users from 130 countries.

“Quizlet has absolutely become a valuable tool,” Sutherland says. “In the United States, half of all high school students and a third of all college students use us every month. That’s not something I expected to happen when I made it in high school, and it speaks to how essential it has become.”

Part of the appeal is that Quizlet takes a simple idea — picture paper flash cards — but gives it a modern twist. Online users create study sets (terms and definitions) or use study sets created by others, including classmates. They then have multiple ways to study the information: virtual flashcards or typing in answers to written or audio prompts. There are also two games: match (drag the correct answer) and gravity (type the correct answer as asteroids fall).

The online format is key, he says. “The appeal of a digital learning tool is that it can ask much more dynamic questions than what you can do with paper. Quizlet can figure out what material you’re struggling with and just focus on that. It can also verify what you know and coach you to only stop studying when it thinks you’re ready.”

Recently, they launched Quizlet Live for students to work in teams during class. Teacher feedback was key, he says, but adds, “My favorite type of feedback is hearing from teachers about new-use cases. The other day I was at a chocolate store and wearing my Quizlet shirt. The woman there said she uses Quizlet to train all their new employees about their chocolate. I want that job!”
