Argumentative Essay Writing Skills

Argumentative Essays


The Modes of Discourse—Exposition, Description, Narration, Argumentation (EDNA)—are common paper assignments you may encounter in your writing classes. Although these genres have been criticized by some composition scholars, the Purdue OWL recognizes the wide spread use of these approaches and students’ need to understand and produce them.

What is an argumentative essay?

The argumentative essay is a genre of writing that requires the student to investigate a topic; collect, generate, and evaluate evidence; and establish a position on the topic in a concise manner.

Please note: Some confusion may occur between the argumentative essay and the expository essay. These two genres are similar, but the argumentative essay differs from the expository essay in the amount of pre-writing (invention) and research involved. The argumentative essay is commonly assigned as a capstone or final project in first year writing or advanced composition courses and involves lengthy, detailed research. Expository essays involve less research and are shorter in length. Expository essays are often used for in-class writing exercises or tests, such as the GED or GRE.

Argumentative essay assignments generally call for extensive research of literature or previously published material. Argumentative assignments may also require empirical research where the student collects data through interviews, surveys, observations, or experiments. Detailed research allows the student to learn about the topic and to understand different points of view regarding the topic so that she/he may choose a position and support it with the evidence collected during research. Regardless of the amount or type of research involved, argumentative essays must establish a clear thesis and follow sound reasoning.

The structure of the argumentative essay is held together by the following.

  • A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.

In the first paragraph of an argument essay, students should set the context by reviewing the topic in a general way. Next the author should explain why the topic is important (exigence) or why readers should care about the issue. Lastly, students should present the thesis statement. It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.

  • Clear and logical transitions between the introduction, body, and conclusion.

Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse. Transitions should wrap up the idea from the previous section and introduce the idea that is to follow in the next section.

  • Body paragraphs that include evidential support.

Each paragraph should be limited to the discussion of one general idea. This will allow for clarity and direction throughout the essay. In addition, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph. Some paragraphs will directly support the thesis statement with evidence collected during research. It is also important to explain how and why the evidence supports the thesis (warrant).

However, argumentative essays should also consider and explain differing points of view regarding the topic. Depending on the length of the assignment, students should dedicate one or two paragraphs of an argumentative essay to discussing conflicting opinions on the topic. Rather than explaining how these differing opinions are wrong outright, students should note how opinions that do not align with their thesis might not be well informed or how they might be out of date.

  • Evidential support (whether factual, logical, statistical, or anecdotal).

The argumentative essay requires well-researched, accurate, detailed, and current information to support the thesis statement and consider other points of view. Some factual, logical, statistical, or anecdotal evidence should support the thesis. However, students must consider multiple points of view when collecting evidence. As noted in the paragraph above, a successful and well-rounded argumentative essay will also discuss opinions not aligning with the thesis. It is unethical to exclude evidence that may not support the thesis. It is not the student’s job to point out how other positions are wrong outright, but rather to explain how other positions may not be well informed or up to date on the topic.

  • A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.

It is at this point of the essay that students may begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize the information presented in the body of the essay. Restate why the topic is important, review the main points, and review your thesis. You may also want to include a short discussion of more research that should be completed in light of your work.

A complete argument

Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of World War II and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the argument in the middle of my second point, questions would arise concerning the current effects on those who lived through the conflict. Therefore, the argumentative essay must be complete, and logically so, leaving no doubt as to its intent or argument.

The five-paragraph essay

A common method for writing an argumentative essay is the five-paragraph approach. This is, however, by no means the only formula for writing such essays. If it sounds straightforward, that is because it is; in fact, the method consists of (a) an introductory paragraph (b) three evidentiary body paragraphs that may include discussion of opposing views and (c) a conclusion.

Longer argumentative essays

Complex issues and detailed research call for complex and detailed essays. Argumentative essays discussing a number of research sources or empirical research will most certainly be longer than five paragraphs. Authors may have to discuss the context surrounding the topic, sources of information and their credibility, as well as a number of different opinions on the issue before concluding the essay. Many of these factors will be determined by the assignment.

Listen to this post as a podcast:


For seven years, I was a writing teacher. Yes, I was certified to teach the full spectrum of English language arts—literature, grammar and usage, speech, drama, and so on—but my absolute favorite, the thing I loved doing the most, was teaching students how to write.

Most of the material on this site is directed at all teachers. I look for and put together resources that would appeal to any teacher who teaches any subject. That practice will continue for as long as I keep this up. But over the next year or so, I plan to also share more of what I know about teaching students to write. Although I know many of the people who visit here are not strictly English language arts teachers, my hope is that these posts will provide tons of value to those who are, and to those who teach all subjects, including writing.

So let’s begin with argumentative writing, or persuasive writing, as many of us used to call it. This overview will be most helpful to those who are new to teaching writing, or teachers who have not gotten good results with the approach you have taken up to now. I don’t claim to have the definitive answer on how to do this, but the method I share here worked pretty well for me, and it might do the same for you. If you are an experienced English language arts teacher, you probably already have a system for teaching this skill that you like. Then again, I’m always interested in how other people do the things I can already do; maybe you’re curious like that, too.

Before I start, I should note that what I describe in this post is a fairly formulaic style of essay writing. It’s not exactly the 5-paragraph essay, but it definitely builds on that model. I strongly believe students should be shown how to move past those kinds of structures into a style of writing that’s more natural and fitting to the task and audience, but I also think they should start with something that’s pretty clearly organized.

So here’s how I teach argumentative essay writing.

Step 1: Watch How It’s Done

One of the most effective ways to improve student writing is to show them mentor texts, examples of excellent writing within the genre students are about to attempt themselves. Ideally, this writing would come from real publications and not be fabricated by me in order to embody the form I’m looking for. (Although most experts on writing instruction employ some kind of mentor text study, the person I learned it from best was Katie Wood Ray in her book Study Driven). Since I want the writing to be high quality and the subject matter to be high interest, I might choose pieces like Jessica Lahey’s Students Who Lose Recess Are the Ones Who Need it Most and David Bulley’s School Suspensions Don’t Work.

I would have students read these texts, compare them, and find places where the authors used evidence to back up their assertions. I would ask students which author they feel did the best job of influencing the reader, and what suggestions they would make to improve the writing. I would also ask them to notice things like stories, facts and statistics, and other things the authors use to develop their ideas. Later, as students work on their own pieces, I would likely return to these pieces to show students how to execute certain writing moves.

Step 2: Informal Argument, Freestyle

Although many students might need more practice in writing an effective argument, many of them are excellent at arguing in person. To help them make this connection, I would have them do some informal debate on easy, high-interest topics. An activity like This or That (one of the classroom icebreakers I talked about last year) would be perfect here: I read a statement like “Women have the same opportunities in life as men.” Students who agree with the statement move to one side of the room, and those who disagree move to the other side. Then they take turns explaining why they are standing in that position. This ultimately looks a little bit like a debate, as students from either side tend to defend their position to those on the other side.

Every class of students I have ever had, from middle school to college, has loved loved LOVED this activity. It’s so simple, it gets them out of their seats, and for a unit on argument, it’s an easy way to get them thinking about how the art of argument is something they practice all the time.

Step 3: Informal Argument, Not so Freestyle

Once students have argued without the support of any kind of research or text, I would set up a second debate; this time with more structure and more time to research ahead of time. I would pose a different question, supply students with a few articles that would provide ammunition for either side, then give them time to read the articles and find the evidence they need.

Next, we’d have a Philosophical Chairs debate (learn about this in my discussion strategies post), which is very similar to “This or That,” except students use textual evidence to back up their points, and there are a few more rules. Here they are still doing verbal argument, but the experience should make them more likely to appreciate the value of evidence when trying to persuade.

Before leaving this step, I would have students transfer their thoughts from the discussion they just had into something that looks like the opening paragraph of a written argument: A statement of their point of view, plus three reasons to support that point of view. This lays the groundwork for what’s to come.

Step 4: Introduction of the Performance Assessment

Next I would show students their major assignment, the performance assessment that they will work on for the next few weeks. What does this look like? It’s generally a written prompt that describes the task, plus the rubric I will use to score their final product.

Anytime I give students a major writing assignment, I let them see these documents very early on. In my experience, I’ve found that students appreciate having a clear picture of what’s expected of them when beginning a writing assignment. At this time, I also show them a model of a piece of writing that meets the requirements of the assignment. Unlike the mentor texts we read on day 1, this sample would be something teacher-created (or an excellent student model from a previous year) to fit the parameters of the assignment.

Step 5: Building the Base

Before letting students loose to start working on their essays, I make sure they have a solid plan for writing. I would devote at least one more class period to having students consider their topic for the essay, drafting a thesis statement, and planning the main points of their essay in a graphic organizer.

I would also begin writing my own essay on a different topic. This has been my number one strategy for teaching students how to become better writers. Using a document camera or overhead projector, I start from scratch, thinking out loud and scribbling down my thoughts as they come. When students see how messy the process can be, it becomes less intimidating for them. They begin to understand how to take the thoughts that are stirring around in your head and turn them into something that makes sense in writing.

For some students, this early stage might take a few more days, and that’s fine: I would rather spend more time getting it right at the pre-writing stage than have a student go off willy-nilly, draft a full essay, then realize they need to start over. Meanwhile, students who have their plans in order will be allowed to move on to the next step.

Step 6: Writer’s Workshop

The next seven to ten days would be spent in writer’s workshop, where I would start class with a mini-lesson about a particular aspect of craft. I would show them how to choose credible, relevant evidence, how to skillfully weave evidence into an argument, how to consider the needs of an audience, and how to correctly cite sources. Once each mini-lesson was done, I would then give students the rest of the period to work independently on their writing. During this time, I would move around the room, helping students solve problems and offering feedback on whatever part of the piece they are working on. I would encourage students to share their work with peers and give feedback at all stages of the writing process.

If I wanted to make the unit even more student-centered, I would provide the mini-lessons in written or video format and let students work through them at their own pace, without me teaching them. (To learn more about this approach, read my post on self-paced learning).

As students begin to complete their essays, the mini-lessons would focus more on matters of style and usage. I almost never bother talking about spelling, punctuation, grammar, or usage until students have a draft that’s pretty close to done. Only then do we start fixing the smaller mistakes.

Step 7: Final Assessment

Finally, the finished essays are handed in for a grade. At this point, I’m pretty familiar with each student’s writing and have given them verbal (and sometimes written) feedback throughout the unit; that’s why I make the writer’s workshop phase last so long. I don’t really want students handing in work until they are pretty sure they’ve met the requirements to the best of their ability. I also don’t necessarily see “final copies” as final; if a student hands in an essay that’s still really lacking in some key areas, I will arrange to have that student revise it and resubmit for a higher grade.


So that’s it. If you haven’t had a lot of success teaching students to write persuasively, and if the approach outlined here is different from what you’ve been doing, give it a try.
