Chapter 13: Expository (Informative) Essays

What is an expository essay.

An expository or informative essay is one that explains a writer’s ideas by defining, explaining, informing, or elaborating on points to allow the reader to clearly understand the concept or topic.  Expository essays seek to inform and educate a reader on a particular topic while still including your own insights, ideas, and conclusions on the issue.

Many of your future academic workplace writing assignments will be expository–explaining your ideas or the significance of a concept or action. An expository essay allows the writer the opportunity to explain his or her ideas about a topic and to provide clarity for the reader by using:

• Explanations
• Definitions

It may also include the writer outlining steps of a procedure in a way that is straightforward for the reader to follow. It is purely informative and often contains elements of summary.

Imagine you need to verbally explain a concept to your classmates, maybe a behavioural theory. What are the key elements on which you would focus? How would you organize the information? You could explain who came up with the theory, the specific area of study to which it is related, its purpose, and the significant details to explain the theory. Telling these four elements to your classmates would give them a complete, yet summarized, picture of the theory, so they could apply the theory in future discussions.

Although you did this verbally, you were still fulfilling the elements of an expository essay by providing definition, details, explanations, and maybe even facts if you have a really good memory. This is the same process that you would use when you write an expository essay. You may actually be doing this all the time; for example, when you are giving someone directions to a place or explaining how to cook something. In the following sections of the chapter, you will practise doing this more in different expository written forms.

The Structure of an Expository Essay

Sections versus Paragraphs

You will recall from the chapter on academic paragraphs that the 5-paragraph model is not the only way to write an essay.  Instead, you should instead think of your essay in terms of sections (there may be five, but if so, that’s coincidence, not a rule), and each section may have multiple paragraphs.

To understand further why you need to think beyond the five-paragraph essay, imagine you have been asked to submit a six-page paper (approximately 1,500 words).  If you were to only use five paragraphs, that paper is going to be a long, jumbled mess.  If your paragraphs are too long, they likely have too many ideas and your reader may become confused.

Instead, if you think of your essays being divided into sections (with possibly more than one paragraph per section), your writing will likely be more organized and allow your reader to follow your presentation of ideas without creating too much distance between your paragraph’s supporting points and its topic sentence.

Consider Your Audience: How Much Do They Know?

Later in this chapter, you will work on determining and adapting to your audience when writing, but with an expository essay, since you are defining or informing your audience on a certain topic, you need to evaluate how much your audience knows about that topic (aside from having general common knowledge). You want to make sure you are giving thorough, comprehensive, and clear explanations on the topic. Never assume the reader knows everything about your topic (even if it is covered in the reader’s field of study). For example, even though some of your instructors may teach criminology, they may have specialized in different areas from the one about which you are writing; they most likely have a strong understanding of the concepts but may not recall all the small details on the topic. If your instructor specialized in crime mapping and data analysis for example, he or she may not have a strong recollection of specific criminology theories related to other areas of study.

However, you also want to be mindful that you are not underestimating your reader and providing information that could be seen as condescending.  Providing enough background information and context without being too detailed is a fine balance, but you always want to ensure you have no gaps in the information, so your reader will not have to guess your intention.

39 Introduction to Informative Writing

Amy Minervini

By Amy Minervini

Exposition is writing that explains, informs, or describes. This type of writing is also known as the informative mode in that the main objective is not to narrate a story or persuade readers of something but rather to convey factual information , including observations and personal/others’ experiences. However, when writing an expository essay, you can include elements from other modes (storytelling, analysis, writer impressions, persuasion, etc.) although these would be secondary aims or even implied. The expository composition is a practical, authentic kind of writing that can stand on its own or serve as the foundation for your more developed research essays.

Key Characteristics

Expository writing generally exhibits the following:

• Emphasis on facts, observations, or personal/others’ experiences
• Organization marked by a logical flow or progression of information; chronological, order of importance/priority, or the step-by-step approach are the most common; transitions that guide the reader
• Close attention paid to detail and description
• No noticeable writer bias

Introduction to the General Expository Essay

The following is excerpted from Crystle Bruno’s Commonsense Composition 3.1 Expository Essay

The main aim of an expository essay is to provide an effective explanation of a topic. While a descriptive essay strives to describe a subject or a narrative essay seeks to show personal growth, an expository essay tries to explain a topic or situation. Thus, expository essays are written as if the writer is explaining or clarifying a topic to the reader. Since an expository essay is trying to clarify a topic, it is important that it provides the categories or reasons that support the clarification of the paper. Moreover, these categories and reasons also provide the framework for the organization of the paper.

Components of the expository essay as the parts of a house.

Much like the categories are essential to clarifying the topic, organization is the key to any well-developed essay. When composing your essay, think of its organization as a house, with each component of an essay representing a major part of a house. Just as the foundation provides support on which a house can be built, a thesis represents the foundation upon which to build an essay. The introductory paragraph then functions as both the door and framework for an expository essay. Like a house door, the introductory paragraph must allow the reader to enter into the essay. Additionally, just as walls are built upon the framework of a house, the body paragraphs of an essay are organized around the framework or organizational scheme, presented in the introductory paragraph. The body paragraphs, much like the walls of a house, must be firm, strong and complete. Also, there must always be as many body paragraphs as the framework of the introductory paragraph indicates otherwise your essay will resemble a house that is missing a wall. Finally, an essay must include a conclusion paragraph that tops off the essay much like a roof completes a house. As the roof cements the structure of the house and helps hold the walls in place, the conclusion paragraph must reiterate the points within your body paragraphs and complete an essay.

Although the overall organization of an expository essay is important, you must also understand the organization of each component (the introductory, body and conclusion paragraphs) of your essay. The chart below identifies the essential parts of each component of your essay, explaining the necessary information for each type of paragraph. While the guidelines listed below may feel constrictive, they are merely meant to guide you as a writer. Ultimately, the guidelines should help you write more effectively. The more familiar you become with how to organize an essay, the more energy you can focus on your ideas and your writing. As a result, your writing will improve as your ability to organize your ideas improves. Plus, focusing your energy on your argument and ideas rather than the organization makes your job as a writer more exciting and fun.

Introductory Paragraph:

• Introduce the issue.
• Present the topic and its explanation or clarification.
• Provide the categories used to explain the topic.
• Provide the thesis statement.

Body Paragraphs:

• Begin with a topic sentence that reflects an explanation of the paper and the category being discussed in the paragraph.
• Support the argument with useful and informative quotes from sources such as books, journal articles, etc.
• Provide 2-3 quotes that connect the category being discussed to the explanation
• Provide 2-3 sentences explaining each quote more full, drawing stronger connections between the category and the explanation.
• Ensure that the information in these paragraphs is important to the thesis statement.
• End each paragraph with a transition sentence which leads into the next body paragraph.

Concluding Paragraph:

• Begin with a topic sentence that reflects the argument of the thesis statement.
• Briefly summarize the main points of the paper.
• Provide a strong and effective close for the paper.

Introductory Paragraphs

A strong introductory paragraph is crucial to the development of an effective expository essay. Unlike an argumentative essay which takes a stand or forms an opinion about a subject, an expository essay is used when the writer wishes to explain or clarify a topic to the reader. In order to properly explain a topic, an expository essay breaks the topic being addressed into parts, explains each component in relation to the whole and uses each component to justify the explanation of the topic. Thus when writing an introductory paragraph, it is crucial to include the explanation or clarification of the topic and the categories or components used to produce this explanation.

Since the success of the paper rests on the introductory paragraph, it is important to understand its essential components. Usually, expository papers fail to provide a clear explanation not because the writer’s lacks explanations or clarifications but rather because the explanations are not properly organized and identified in the introductory paragraph. One of the most important jobs of an introductory paragraph is that it introduces the topic or issue. Most explanations cannot be clarified without at least some background information. Thus, it is essential to provide a foundation for your topic before you begin explaining your topic. For instance, if you wanted to explain what happened at the first Olympic Games, your introductory paragraph would first need to provide background information about how the first games happened. In doing so, you ensure that your audience is as informed about your topic as you are and thus you make it easier for your audience to understand your explanation.

Below is a table describing and explaining the main jobs of the introductory paragraph.

Introductory paragraphs introduce the topic and suggest why it is important.

Example:   An analysis of the essay exam results of the new English class shows that the new class format promotes close reading and better essay organization.

This sentence tells the reader both that the topic of the paper will be the benefits of the new English class and that the significance of these benefits is the improvement of close reading and essay organization.

Introductory paragraphs outline the structure of the paper and highlight the main ideas.

Example:   Considering the results of the High School Exit Exam, it is apparent that school curriculum is not properly addressing basic math skills such as fractions, percentages and long division.

This sentence indicates that main ideas (fractions, percentages and long division) of the essay and indicates the order in which they will be presented in the body paragraphs.

Introductory paragraphs state the thesis.

Example:   California high schools will require all students to take a resume and cover letter writing workshop in order to better prepare them for employment.

This thesis statement indicates the explanation of the paper.

In addition to introducing the topic of your paper, your introductory paragraph also needs to introduce each of the arguments you will cover in your body paragraphs. By providing your audience with an idea of the points or arguments you will make later in your paper, your introductory paragraph serves as a guide map, not only for your audience but also for you. Including your main sub-points in your introduction not only allows your audience to understand where your essay is headed but also helps you as a writer remember how you want to organize your paper. This is especially helpful if you are not writing your essay in one sitting as it allows you to leave and return to your essay without forgetting all of the important points you wanted to make.

Most importantly, when writing an introductory paragraph, it is essential to remember that you must capture the interest of your reader. Thus, it is your job as the writer to make the introduction entertaining or intriguing. In order to do so, consider using a quotation, a surprising or interesting fact, an anecdote or a humorous story. While the quotation, story or fact you include must be relevant to your paper, placing one of these at the beginning of your introduction helps you not only capture the attention or the reader but also introduce your topic and argument, making your introduction interesting to your audience and useful for your argument and essay.

Body Paragraphs

In an expository essay the body paragraphs are where the writer has the opportunity to explain or clarify his or her viewpoint. By the conclusion paragraph, the writer should adequately clarify the topic for the reader. Regardless of a strong thesis statement that properly indicates the major sub-topics of the essay, papers with weak body paragraphs fail to properly explain the topic and indicate why it is important. Body paragraphs of an expository essay are weak when no examples are used to help illuminate the topic being discussed or when they are poorly organized. Occasionally, body paragraphs are also weak because the quotes used complicate from rather than simplify the explanation. Thus, it is essential to use appropriate support and to adequately explain your support within your body paragraphs.

In order to create a body paragraph that is properly supported and explained, it is important to understand the components that make up a strong body paragraph. The bullet points below indicate the essential components of a well-written, well-argued body paragraph.

Body Paragraph Components

• Support the argument with useful and informative quotes from sources such as books, journal articles, expert opinions, etc.
• Provide 1-2 sentences explaining each quote.
• Provide 1-3 sentences that indicate the significance of each quote.
• Ensure that the information provided is relevant to the thesis statement.
• End with a transition sentence which leads into the next body paragraph.

Just as your introduction must introduce the topic of your essay, the first sentence of a body paragraph must introduce the main sub-point for that paragraph. For instance, if you were writing a body paragraph for a paper explaining the factors that led to US involvement in World War II, one body paragraph could discuss the impact of the Great Depression on the decision to enter the war. To do so, you would begin with a topic sentence that explains how the Great Depression encouraged involvement in the war because the war effort would stimulate certain aspects of the economy. Following this sentence, you would go into more detail and explain how the two events are linked. By placing this idea at the beginning of the paragraph, not only does your audience know what the paragraph is explaining, but you can also keep track of your ideas.

Following the topic sentence, you must provide some sort of fact that supports your claim. In the example of the World War II essay, maybe you would provide a quote from a historian or from a prominent history teacher or researcher. After your quote or fact, you must always explain what the quote or fact is saying, stressing what you believe is most important about your fact. It is important to remember that your audience may read a quote and decide it is indicating something entirely different than what you think it is explaining. Or, maybe some or your readers think another aspect of your quote is important. If you do not explain the quote and indicate what portion of it is relevant to your clarification, than your reader may become confused or may be unconvinced of your explanation. Consider the possible interpretations for the statement below.

Example:  While the U.S. involvement in World War II was not the major contributor to the ending of the Great Depression, the depression was one of the primary motives for entering the war.

Interestingly, this statement seems to be saying two things at once – that the Great Depression helped spark involvement in the war and that World War II did not end the depression alone. On the one hand, the historian seems to say that the two events are not directly linked. However, on the other hand, the historian also indicates that the two events are linked in that the depression caused U.S. involvement in the war. Because of the tension in this quotation, if you used this quote for your World War II essay, you would need to explain that the significant portion of the quote is the assertion that links the events.

In addition to explaining what this quote is saying, you would also need to indicate why this is important to your explanation. When trying to indicate the significance of a fact, it is essential to try to answer the “so what.” Image you have just finished explaining your quote to someone and they have asked you “so what?” The person does not understand why you have explained this quote, not because you have not explained the quote well but because you have not told him or her why he or she needs to know what the quote means. This, the answer to the “so what,” is the significance of your paper and is essentially your clarification within the body paragraphs. However, it is important to remember that generally a body paragraph will contain more than one quotation or piece of support. Thus, you must repeat the Quotation-Explanation-Significance formula several times within your body paragraph to fully explain the one sub-point indicated in your topic sentence. Below is an example of a properly written body paragraph.

Example of an expository body paragraph paired with an explanation of its parts.

Conclusion Paragraph

The conclusion paragraph of an expository essay is an author’s last chance to create a good impression. Hence, it is important to restate the thesis statement at the beginning of the paragraph in order to remind the reader of your topic and explanation. Since it is at the end of the paper, the conclusion paragraph also should add a sense of closure and finality to the clarification of the paper. It is important to re-emphasize the main idea without being repetitive or introducing an entirely new idea or subtopic. While you can conclude your conclusion paragraph by suggesting a topic for further research or investigation, do not make this question the focus of the paragraph. Thus, you should briefly and concisely reiterate the strongest clarifications of the paper, reminding the reader of the validity of your thesis or explanation and bringing closure to your paper.

You may feel that the conclusion paragraph is redundant or unnecessary; However, do not forget that this is your last chance to explain the significance of your argument to your audience. Just as your body paragraphs strive to present the significance of each fact or quote you use, your conclusion paragraph should sum up the significance of your argument. Thus, you should consider making a bold statement in your concluding paragraph by evoking a vivid image, suggesting results or consequences related to your argument or ending with a warning. Through using these components, you not only make your conclusion paragraph more exciting, but you also make your essay and your argument, more important.

What Is Expository Writing?

How to Write an Expository Essay

• Ph.D., Rhetoric and English, University of Georgia
• M.A., Modern English and American Literature, University of Leicester
• B.A., English, State University of New York

Expository writing is used to convey factual information (as opposed to creative writing, such as fiction). It is the language of learning and understanding the world around us. If you've ever read an encyclopedia entry, a how-to article on a website, or a chapter in a textbook, then you've encountered examples of expository writing.

Key Takeaways: Expository Writing

• Just the facts, M'am: Expository writing is informational, not creative writing.
• Anytime you write to describe or explain, you use expository writing.
• Use a logical flow when planning an expository essay, report, or article: introduction, body text, and conclusion.
• It's often easier to write the body of your article first, before composing the introduction or conclusion.

Expository writing is everywhere in everyday life, not just academic settings, as it's present anytime there's information to be conveyed. It can take form in an academic paper, an article for a newspaper, a report for a business, or even book-length nonfiction. It explains, informs, and describes.

Types of Expository Writing

In  composition studies , expository writing (also called exposition ) is one of the four traditional  modes of discourse . It may include elements of  narration ,  description , and  argumentation . Unlike creative or  persuasive writing , which can appeal to emotions and use anecdotes, expository writing's primary  purpose  is to deliver information about an issue, subject, method, or idea using facts.

Exposition may take one of several forms:

• Descriptive/definition:  In this style of writing, topics are defined by characteristics, traits, and examples. An encyclopedia entry is a kind of descriptive essay. 
• Process/sequential:  This essay outlines a series of steps needed in order to complete a task or produce something. A recipe at the end of an article in a food magazine is one example.
• Comparative/contrast:  This kind of exposition is used to demonstrate how two or more subjects are the same and different. An article that explains the difference between owning and renting a home and the benefits and drawbacks of each is one such an example.
• Cause/effect:  This kind of essay describes how one step leads to a result. An example is a personal blog chronicling a workout regimen and documenting the results over time.
• Problem/solution: This type of essay presents a problem and possible solutions, backed by data and facts, not just opinion.
• Classification: A classification essay breaks down a broad topic into categories or groupings.

Tips for Expository Writing

As you write, keep in mind some of these tips for creating an effective expository essay:

Start where you know the information best. You don't have to write your introduction first. In fact, it might be easier to wait until the end for that. If you don't like the look of a blank page, move over the slugs from your outline for the main body paragraphs and write the topic sentences for each. Then start putting in your information according to each paragraph's topic.

Be clear and concise.  Readers have a limited attention span. Make your case succinctly in language that the average reader can understand. 

Stick to the facts.  Although an exposition can be persuasive, it should not be based on opinion only. Support your case with facts, data, and reputable sources that can be documented and verified.

Consider voice and tone.  How you address the reader depends on the kind of essay you're writing. An essay written in the first person is fine for a personal travel essay but is inappropriate if you're a business reporter describing a patent lawsuit. Think about your audience before you begin writing.

Planning Your Essay

• Brainstorm: Jot down ideas on a blank piece of paper. Connect them with arrows and lines, or just make lists. Rigor doesn't matter at this stage. Bad ideas don't matter at this stage. Just write down ideas, and the engine in your head will lead you to a good one. When you've got that idea, then repeat the brainstorming exercise with ideas that you want to pursue on that topic and information you could put in. From this list, you'll start to see a path emerge for your research or narrative to follow.
• Compose your thesis: When your ideas coalesce into a sentence in which you can summarize the topic you're writing about, you're ready to compose your thesis sentence. Write down in one sentence the main idea that you'll explore in your paper.
• Examine your thesis: Is it clear? Does it contain opinion? If so, revise that out. For this type of essay, you stick to the facts and evidence. This isn't an editorial. Is the thesis' scope manageable? You don't want your topic too narrow or too broad to be covered in the amount of space you have for your paper. If it's not a manageable topic, refine it. Don't be dismayed if you have to come back and tweak it if your research finds that your initial idea was off-kilter. It's all just part of the process of focusing the material.
• Outline: It may seem inconsequential, but making even a quick outline can save you time by organizing your areas of pursuit and narrowing them down. When you see your topics in an organized list, you may be able to discard off-topic threads before you research them—or as you're researching them and you find they just don't work.
• Research: Find your data and sources to back up the areas you want to pursue to support your thesis statement. Look for sources written by experts, including organizations, and watch for bias. Possible sources include statistics, definitions, charts and graphs, and expert quotes and anecdotes. Compile descriptive details and comparisons to make your topic clear to your reader, when applicable.

What Is an Expository Essay?

An expository essay has three basic parts: the introduction, the body, and the conclusion. Each is crucial to writing a clear article or effective argument.

The introduction: The first paragraph is where you'll lay the foundation for your essay and give the reader an overview of your thesis. Use your opening sentence to get the reader's attention, and then follow up with a few sentences that give your reader some context for the information you're about to cover.

The body:  At a minimum, include three to five paragraphs in the body of your expository essay. The body could be considerably longer, depending on your topic and audience. Each paragraph begins with a topic sentence where you state your case or objective. Each topic sentence supports your overall thesis statement. Then, each paragraph includes several sentences that expand on the information and/or support the topic sentence. Finally, a concluding sentence offers a transition to the following paragraph in the essay.

The conclusion:  The final section of your expository essay should give the reader a concise overview of your thesis. The intent is not merely to summarize your argument but to use it as a means of proposing further action, offering a solution, or posing new questions to explore. Don't cover new material related to your thesis, though. This is where you wrap it all up.

Expository Examples

An expository article or report about a lake, for example, could discuss its ecosystem: the plants and animals that depend on it along with its climate. It could describe physical details about its size, depth, amount of rainfall each year, and the number of tourists it receives annually. Information on when it was formed, its best fishing spots, or its water quality could be included, depending on the audience for the piece.

An expository piece could be in third person or second person. Second-person examples could include, for example, how to test lake water for pollutants or how to kill invasive species. Expository writing is useful and informative.

In contrast, someone writing a creative nonfiction article about a lake might relate the place to a defining moment in his or her life, penning the piece in first person. It could be filled with emotion, opinion, sensory details, and even include dialogue and flashbacks. It's a much more evocative, personal type of writing than an expository piece, even though they're both nonfiction styles.

Expository Writing vs. Informative Writing

The goals of most genres of writing are to convey information or experiences. Expository and informative writing, like any other types, are not exempt. While these forms have similarities, they also differ quite considerably. Understanding a variety of different sorts of writings allows you to adapt your strategy to best fit the needs of your material and goals, allowing you to create the ideal essay for every purpose.

The goal of expository writing, in other words, is to explain, educate, and describe. This type of writing revolves around an argument that the author constructs as a consequence of study and observation. During class essays and exams in a college course, you will most likely be required to do expository writing. Informative writings, on the other hand, are intended to present information fully but without expressing the writer’s viewpoint.

While the essayist may touch on advantages and disadvantages, give them equal consideration regardless of your own opinion since informative writing’s aim is to communicate information without implying a definitive conclusion.

Expository writing, on occasion, incorporates creative features. While the aim of this composition style is to persuade rather than to experiment with unusual or lovely phrases, making an effective case is simpler if you first capture your audience’s attention.

As a result, expository writing frequently has a fun tone or an innovative phrase as part of its objective to make an argument in a unique manner so that it can win over the reader. In an informative document, you are simply performing a task rather than creating something new. An informative article is more functional than creative since you’re just delivering information.

Organization

Expository writing is meant to explain things in a clear and convincing manner. As a result, its organization is crucial. Circumlocution is one of the most frequent organizing methods of expository essays, in which the author describes the subject and supports it with an equivalent example. Narrative interspersion involves introducing a shorter tale, such as an anecdote, within the main narrative with the goal of adding clarity and making information more convincing. In many situations, informative writing allows for great flexibility in structure.

Informative essays are not required to include an introduction, supporting body paragraphs, or a conclusion. Instead of following this structure, the material should be presented in the order that makes the most sense. A writer creating an essay on deer migration patterns, for example, might start with an informative paragraph on the creatures’ habits.

However, despite the freestyle of writing, it is critical to make a statement of purpose early on in the essay so that readers know what information they may anticipate gaining from the informative section.

Construction

The writer may not take for granted that the reader has any prior knowledge of the topic when creating an expository piece. As a result, while the language may be creative, it must remain crystal clear and should not become convoluted or flowery.

Writers create an introduction, body, and conclusions linked by smooth, logical transitions between ideas and phrases when writing in an expository style. Since the goal of expository writing is to persuade readers to accept a thesis, body paragraphs provide compelling evidence and backing for conclusions. Information gathering is the basis of this sort of writing.

You can’t write an effective informative article without a thorough understanding of all pertinent information on the subject. As part of their job, writers who want to create informative essays must become specialists in their fields.

What is an expository essay?

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner. This can be accomplished through comparison and contrast, definition, example, the analysis of cause and effect, etc.

Please note : This genre is commonly assigned as a tool for classroom evaluation and is often found in various exam formats.

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

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

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.

• Body paragraphs that include evidential support.

Each paragraph should be limited to the exposition of one general idea. This will allow for clarity and direction throughout the essay. What is more, 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.

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

Often times, students are required to write expository essays with little or no preparation; therefore, such essays do not typically allow for a great deal of statistical or factual evidence.

• A bit of creativity!

Though creativity and artfulness are not always associated with essay writing, it is an art form nonetheless. Try not to get stuck on the formulaic nature of expository writing at the expense of writing something interesting. Remember, though you may not be crafting the next great novel, you are attempting to leave a lasting impression on the people evaluating your essay.

• 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 will inevitably 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 and come to a conclusion concerning the information presented in the body of the essay.

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 the Great Depression 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 exposition in the middle of my second point, questions would arise concerning the current effects on those who lived through the Depression. Therefore, the expository 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 expository 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:

• an introductory paragraph
• three evidentiary body paragraphs
• a conclusion

Writing an Informative Essay

Informative essays engage readers with new, interesting, and often surprising facts and details about a subject. Informative essays are educational; readers expect to learn something new from them. In fact, much of the reading and writing done in college and the workplace is informative. From textbooks to reports to tutorials like this one, informative writing imparts important and useful information about a topic.

This tutorial refers to the sample informative outline and final essay written by fictional student Paige Turner.

Reasons to Write Informatively

Your purpose for writing and the audience for whom you are writing will impact the depth and breadth of information you provide, but all informative writing aims to present a subject without opinions or bias. Some common reasons to write informatively are to

• report findings that an audience would find interesting,
• present facts that an audience would find useful, and
• communicate information about a person, place, event, issue, or change that would improve an audience’s understanding.

Characteristics of Informative Essays

Informative essays present factual information and do not attempt to sway readers’ opinions about it. Other types of academic and workplace writing do try to influence readers’ opinions:

• Expository essays aim to expose a truth about an issue in order to influence how readers view the issue.
• Persuasive essays aim to influence readers’ opinions, so they will adopt a particular position or take a certain course of action.

Expository and persuasive essays make “arguments.” The only argument an informative essay makes is that something exists, did exist, is happening, or has happened, and the point of the essay is not to convince readers of this but to tell them about it.

• Informative essays seek to enlighten and educate readers, so they can make their own educated opinions and decisions about what to think and how to act.

Strategies for Writing Informatively

Informative essays provide useful information such as facts, examples, and evidence from research in order to help readers understand a topic or see it more clearly. While informative writing does not aim to appeal emotionally to readers in order to change their opinions or behaviors, informative writing should still be engaging to read. Factual information is not necessarily dry or boring. Sometimes facts can be more alarming than fiction!

Writers use various strategies to engage and educate readers. Some strategies include

• introducing the topic with an alarming fact or arresting image;
• asserting what is true or so about the subject in a clear thesis statement;
• organizing the paragraphs logically by grouping related information;
• unifying each paragraph with a topic sentence and controlling idea;
• developing cohesive paragraphs with transition sentences;
• using precise language and terminology appropriate for the topic, purpose, and audience; and
• concluding with a final idea or example that captures the essay’s purpose and leaves a lasting impression.

Five Steps for Getting Started

1. Brainstorm and choose a topic.

• Sample topic : The opioid epidemic in the United States.
• The opiod epidemic or even opiod addiction would would be considered too broad for a single essay, so the next steps aim to narrow this topic down.

2. Next, write a question about the topic that you would like to answer through research.

• Sample question : What major events caused the opioid crisis in the United States?
• This question aims to narrow the topic down to causes of the epidemic in the US.

3. Now go to the Purdue Global Library to find the answers to your research question.

As you begin reading and collecting sources, write down the themes that emerge as common answers. Later, in step four, use the most common answers (or the ones you are most interested in writing and discussing) to construct a thesis statement.

• Sample answers: aggressive marketing, loopholes in prescription drug provider programs, and economic downturn.

4. Next, provide purpose to your paper by creating a thesis statement.

The thesis attempts to frame your research question. The sample thesis below incorporates three of the more common answers for the research question from step two: What caused the opioid crisis in the United States?

• Thesis Statement : Aggressive marketing, loopholes in prescription drug provider programs, and economic downturn contributed to the current opioid crisis in the United States.
• Writing Tip : For additional help with thesis statements, please visit our Writing a Thesis Statement article. For help with writing in 3rd person, see our article on Formal Vs. Informal Writing .

5. Now follow each numbered step in the “Suggested Outline Format and Sample” below.

Sample answers have been provided for “I. Introduction” and “II. First Cause.” A complete sample outline can be seen here. A complete sample informative essay can be seen here.

Suggested Outline Format and Sample

I. INTRODUCTION

A. First provide a topic sentence that introduces the main topic: Sample topic sentence : There is a current prescription pain medication addiction and abuse epidemic possibly caused by an excessive over prescription of these medications.

B. Now provide a couple sentences with evidence to support the main topic: Sample sentence one with evidence to support the main topic : According to Dr. Nora Volkow, Director of National Institute on Drug Abuse (NIDA), in testimony before the 115th Congress, “In 2016, over 11 million Americans misused prescription opioids … and 2.1 million had an opioid use disorder due to prescription opioids” (Federal Efforts to Combat the Opioid Crisis, 2017, p. 2).

C. Sample sentence two with evidence to support the main topic : Volkow indicated “more than 300,000 Americans have died of an opioid overdose” since 2013 (Federal Efforts to Combat the Opioid Crisis, 2017, p.2).

D. Sample sentence three with evidence to support the main topic : According to Perez-Pena (2017), the Center for Disease Control and Prevention reported more than 25,000 people in the United States died in 2015 from overdosing on opioids Fentanyl, Oxycodone, and Hydrocodone.

E. Toward the end of the introduction, include your thesis statement written in the 3rd-person point-of-view: Sample thesis statement : Potential solutions to the growing opioid epidemic may be illuminated by examining how opioid addiction is triggered through aggressive pharmaceutical marketing, how opioid addiction manifests among prescribed patients, and how economic downturns play a role in the increase of opioid addiction.

F. Write down the library sources you can use in this introductory paragraph to help support the main topic.

• Federal Efforts to Combat the Opioid Crisis, 2017
• Perez-Pena, 2017
• Writing Tip : For more help writing an introduction, please refer to this article on introductions and conclusions .

II. FIRST CAUSE

A. First provide a topic sentence that introduces the first cause of the opioid epidemic: Sample topic sentence that introduces the first cause : One issue that helped contribute to the opioid epidemic is aggressive marketing by pharmaceutical manufacturers.

B. Now provide sentences with evidence to support the first cause: Sample sentence one with evidence that supports the first cause : 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.

C. Sample sentence two with evidence to support the first cause : 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).

D. Next, add more information or provide concluding or transitional sentences that foreshadows the upcoming second cause: Sample concluding and transitional sentence that foreshadow the second cause : Although aggressive marketing by pharmaceutical companies played a large role in opioid addiction, patients are to blame too, as many take advantage of holes in the healthcare provider system in order to remedy their addiction.

E. Write down the library sources you can use in this body paragraph to help support the first cause:

Argumentation

Expository and Informational Writing

Across-the-curriculum.

Expository/Informational Writing conveys information or educates a reader on a topic. In academic settings, the expository/informational response or essay is the most widespread of all the modes of writing because most content area teachers ask students to explain new learning through writing. Students are given a content-specific topic and are asked to write about the topic in a short-constructed response, an essay, or a research paper. Both formative assessments and summative assessments require writing. So, even when students know the answer to a question, many times they struggle to write their answers effectively. That's where Jane Schaffer Academic Writing® comes to the rescue!

Benefits of Expository and Informational Writing

JSWP uses common terminology that allows teachers and students to talk about writing from a shared perspective and understanding. Through every step of the writing process, teachers are able to communicate clearly their expectations, and students can meet those expectations in their written responses. Students no longer anxiously wonder if they are delivering what the teacher wants, and teachers have language to provide solid instruction in order to teach writing rather than just assign writing.

After thirty-five years of reviewing writing samples for ever-evolving high-stakes tests, including state and national tests, Advanced Placement® exams, and the International Baccalaureate Program, Dr. Louis and the Jane Schaffer Academic Writing Program provide teachers and students with insight and skill regarding expository/informational writing to achieve higher scores.

JSWP helps teachers learn how to design the most effective expository/informational response or essay prompts, and students learn the important skill of decoding these writing prompts so that the students know the specifics of a writing assignment before the writing begins. There are no more blank stares or confusion about the purpose of the writing assignment.

The JSWP color-coded method of writing also applies to close reading. Students learn to annotate their texts in the same colors that they learned in their JSWP writing lessons so that students make connections between their close reading of a text and their own writing across-the-curriculum.

JSWP helps students to understand how to evaluate and use the best evidence to support their assertions when writing an expository/informational response or essay.

Providing insightful, thoughtful, and erudite analysis can be one of the most difficult challenges for educators to teach and one of the most frustrating and ambiguous ideas and skills for students to understand and learn. JSWP provides a method of asking questions and unpacking thoughts so that those thoughts transfer from the students’ minds onto their papers or computer screens.

JSWP offers specific expository/informational graphic organizers. Students follow a prewriting process to draft their writing assignments; and through the famous "JSWP Shaping Sheet," they practice grammar skills, integrate effective transitions, improve their vocabulary, and learn revision and editing techniques prior to submitting their writing assignments to their teachers for a grade.

Expository vs. Informative Essay – A Quick Tutorial

Writing an essay constitutes many things among which is the understanding of different types of compositions as well as how to go about them. At lower levels of academia, students are always asked to partake in writing narrative compositions and this is the knowledge they grow up with. Writing such compositions in middle school through to high school has retained its foundational principle in shaping the capability of students when it comes to writing. In this regard, many will always grow up fully aware of what writing tasks waits for them in the near future when they transition to higher levels of learning such as colleges. Well, it is in college where students then start to get exposed to multiple types of writing with an essay such as expository coming to the fore.

Other types of composition in which students become largely engaged in writing at the advanced level of learning include an informative piece. There is a thin line between expository and informative writing. This is usually attributed to the fact that both serve the same function which is to relay information. However, when the two are to be looked at strictly, informative and expository literary writing bear strong differences with the latter based on writing something from an authoritative point of view with the assumption that readers are not aware of it. The other case of informative writing is rather common and straightforward and in which case, one will always craft a literary material on information the public deserves to know, and in this case, students. In this post, we take a leap further into some distinctive features of the two types of writing.

Differences in purpose

People always decide to write my college essay today for a reason, and when it comes to doing an expository or an informative essay, the same applies. This is all about the purpose for which you write. While an expository article is all about explaining and even giving descriptions, informative articles stick to informing with no room for giving opinions.

Tone as a distinguishing characteristic

The tone is the voice one can get when reading a literary piece and it varies from one type of article to another. While informative articles employ formal and direct voice, expository types give room for creativity and the use of persuasive tone.

Organization

This is another distinguishing factor. Informative pieces are not strict on this while the expository write up drawing their strength from the manner in which ideas are organized.

Informative, Compare and Contrast, and Persuasive Essay Composing of Fifth and Seventh Graders: Not All Essay Writing Is the Same

Matt davidson.

1 University of Washington, Seattle, USA

Virginia Berninger

Typically developing writers in fifth ( n = 110, M = 10 years 8 months) or seventh ( n = 97, M = 12 years 7 months) grade wrote informative, compare and contrast, and persuasive essays for which the content was held constant—two mountains with a history of volcanic eruption. Relevant background knowledge was provided by reading text and showing colorful illustrations to the students before writing each genre. Results showed considerable variability between genre pairs within and across individual writers in content quality, organization quality, and length. Results, which support multiple expository genres, are consistent with prior research showing multiple genres (narrative vs. expository or even within narrative). Results are discussed in reference to the importance of assessing multiple genres in inferring composing expertise as emphasized by Olinghouse and colleagues.

Sources of Variation in Written Composition

Generativity of language.

Any assessment study that wishes to draw conclusions about writing ability based on written products faces a host of confounding variables and numerous sources of variance. Chomsky (2006) called attention to the generativity of language—the same language units can be combined in multiple ways to express thought. Likewise, the same word can be used to express different ideas, and the same idea can be expressed with different words ( Stahl & Nagy, 2005 ). Words can be combined in different ways within syntax to express comparable ideas, and the same idea can be expressed in multiple multi-word syntactic structures (Chomsky). Likewise, written composition is generative: Thought can be translated into a variety of genres or discourse structures, and discourse structures can be translated into a variety of kinds of thoughts ( Fayol, Alamargot, & Berninger, 2012 ). Thus, generativity of language is one source of individual differences in composing.

Features of the writing prompt, which establishes the topic, may also be an important source of variance in essay ratings. Schoonen (2005) had sixth-grade students write four essays, each of which was analyzed both holistically and analytically by raters, in terms of their organization, content, and language use. Using a structural equation model to estimate the variance components in students’ scores, he found, among other things, more variance due to different writing prompts than due to raters. Kobrin, Deng, and Shaw (2011) , who studied prompt characteristics for SAT writing tasks, found that prompts which presented two sides of an argument led writers to produce slightly longer texts. On the other hand, the topic may not be the only source of variance in quality of writing. In their study, van den Bergh, De Maeyer, van Wiejen, and Tillema (2012) found that holistic ratings of essay quality were not so dependent on topics. Regardless of the prompt used, a single writing topic may not be adequate to assess composing ability, as explained in the next section, “Genre.”

Writing genre may also matter in assessing composing ability. Olinghouse, Santangelo, and Wilson (2012) examined the validity of “single-occasion, single-genre, holistically scored” pieces of writing (p. 55). They specifically investigated the validity of drawing an inference from a single score to the student’s writing ability across both genres and curricular requirements. After having participants compose in three genres (story, informative, and persuasive), the authors computed correlations of individual compositions across genre pairs. They argued that strong correlations would indicate similar rank ordering across genre, while low or moderate would show different orderings for students. For their set of fifth-grade participants, Olinghouse et al. (2012) found moderate correlations across genre pairs for the holistic quality ratings (.37–.48), with lower correlations for genre elements (.12–.23).

Others have studied the genre-related linguistic skills needed for written composing. Some of this line of research on genre has been related to taking annual tests yoked to state standards ( Troia & Olinghouse, 2013 ). For example, Beck and Jeffery (2007) investigated which genres students were producing for high-stakes state assessments in Texas, California, and New York. The authors provided a framework for detecting genre features related to specific linguistic structures such as particular phrases that are associated with a particular genre. Indeed, much of the current research on genre is grounded in prior research showing that oral as well as written discourse knowledge informs quality of genre writing ( Gillespie, Olinghouse, & Graham, 2013 ; Olinghouse & Graham, 2009 ; Scott, 1994 ) and so does vocabulary knowledge ( Olinghouse & Wilson, 2013 ).

Yet others have studied the contrasting cognitive processes involved in composing different genres, ranging from the hard work to the play involved, as illustrated by the two examples that follow. Olive, Favart, Beauvais, and Beauvais (2009) studied the cognitive effort required to compose narrative and argumentative texts using a reaction time task in which fifth and ninth graders pressed a button with their non-dominant hand each time they heard a beep during a writing task. Ninth graders appeared to exert less effort than fifth graders only for the argumentative texts. The researchers also measured the number and diversity of types of connectives, such as transition words, conjunctions, and logical connectors which tie text together, in each genre. They found that ninth graders used more, and more diverse, connective phrases in general than fifth graders, but that more connectives were used by both fifth and ninth graders in argumentative than narrative genre. Boscolo, Gelati, and Galvan (2012) , in contrast, studied play with multiple narrative genres in written expression. For example, personal narratives and third person narratives may have very different text content and organization and use different vocabulary choices.

Genre also influences writing through writing–reading relationships. Much of school writing involves writing summaries of what has been read or writing reports based on a variety of source material, which also varies in genres ( Moore & MacArthur, 2012 ). So genre may influence both read and written texts.

Research Aims of the Current Study

In contrast to some studies that investigate only one of the many writing genres, this study investigated multiple writing genres within expository writing; although essay writing is sometimes assumed to be a homogeneous genre in contrast to narrative writing, there are actually multiple genres of essay writing. Little is known, however, about whether a single aptitude for expository writing underlies all essay writing or is specific to the kind of essay being written. Whereas some research on multiple writing genres has focused on the early grades (e.g., Kamberelis, 1999 ), the current study focused on multiple genres in the upper elementary (fifth) and middle of middle school (seventh) grades. A sizable body of research has investigated effective ways to teach developing writers to compose in a variety of genres—both typically developing and those who struggle for a variety of reasons, including but not restricted to specific learning disabilities (SLDs; e.g., Boscolo et al., 2012 ; Epstein-Jannai, 2004 ; Troia, 2009 ). In contrast, the current study was designed to be part of the larger line of research on improving assessment of composition across genres. Such assessment research could have important applications to (a) large-scale writing assessments of genre for all students in the Common Core Era including those with SLDs (e.g., Olinghouse & Colwell, 2013 ), and (b) individually administered clinical assessments for students with a variety of school-related learning problems or talents.

Both correlations and mean difference were examined for assessing three kinds of essays during middle childhood and early adolescence—informative, compare/contrast, and persuasive. Two kinds of correlations were examined—Pearson product moment correlations ( r s) and intra-class correlation coefficients (ICCs). The first is sensitive to intra-individual differences within students. The second is sensitive to inter-individual differences among students. The first hypothesis tested was that fifth graders and seventh graders would exhibit intra-individual differences across the three kinds of essays, as evidenced by low to moderate r s across pairs of essays on quality ratings for content and organization. That is, each student may exhibit relative strengths or relative weaknesses in the kinds of essay writing that is easier for her or him. The second hypothesis tested was that the fifth and seventh graders would show significant and sizable ICCs, indicating sizable differences among participants in the different kinds of essay writing. Evidence of such differences within and among students would provide further evidence for the generativity of composing across three genres of essay writing.

Participants

Both groups were in Year 5 of a 5-year longitudinal study of typical oral and written language development when the writing samples analyzed in the current study were collected. One group, which began in first grade, was in fifth grade ( n = 110; 44% male, 56% female). Their mean age was 10 years 8 months (128.50 months, SD = 3.64). They represented the diversity present in the local school population where the study was conducted: European American (64.8%), Asian American (23.4%), African American (6.3%), Hispanic (1.6%), Native American (1.6%), and other (2.3%). The other group, which began in third grade, was in seventh grade ( n = 97; 49.5% male, 50.5% female). Their mean age was 12 years 7 months (151.21 months, SD = 3.71). They were similarly representative of the local diversity: European American (65.5%), Asian American (21.2%), African American (9.7%), Hispanic (0.9%), and other (2.7%). A variety of educational levels were also represented by parents, from no high school education to completion of a graduate degree, of students at both grade level, but the mode was college.

Writing samples were collected during the 4-hr annual visit to the university where the research was conducted with frequent breaks in between activities. Each child wrote three essays, each representing a different genre of expository writing, with topic held constant (Mt. Rainier and Mt. St. Helens). All essays were written on the same day, with brief breaks in between, in a constant order, as is common in longitudinal psychoeducational assessment research. To control for potential differences in background knowledge, before each essay, the researcher gave each participant paper copies of background information about the mountains, and then read that information out loud as the student read along silently. Essays were written in the following constant order by all participating typically developing writers: an informative essay discussing the seasonal changes on Mt. Rainier, an essay comparing and contrasting Mt. St. Helens and Mt. Rainier, and a persuasive essay, stating and defending an opinion on some controversies about the mountains. Participants were given 5 min to write each composition, and if they stopped writing before 5 min elapsed, they could be prompted up to twice to keep writing. Specific instructions were as follows:

• Please read silently while I read aloud this text about Mt. Rainier, which has the title, “The Many Seasons at Mt. Rainier National Park.” Now look at these post cards that depict the different seasons at the mountain and how the mountain seems to change with the seasons. Now please write an informative essay that describes Mt. Rainier which has the title, “The Changing/Changeless Mt. Rainier,” so that someone who has never visited the mountain can visualize what it looks like.
• Please read silently while I read aloud this text that contains many facts about both Mt. St. Helens and Mt. Rainier. Now compare and contrast these mountains. Write a descriptive essay that tells how the mountains are alike and that tells how they are different. (Allow up to 5 min to write.)
• Now read along silently while I read aloud another text about the controversies regarding these mountains. Controversies mean that different people have different opinions or points of view. Now I want you to write a persuasive essay in which you explain the different points of view about each controversy, give your opinion or point of view about each controversy, and defend your argument and convince the reader against the opposing opinion or point of view.

Content and organization coding scheme

All essays were coded for the quality of the content and the quality of the organization. A description of that coding, which was developed by the coauthors over a 3-month period based on much reading and rereading of the essays and related discussion, is presented next. This coding was constructed to be comparable across all three expository essay types—informative, compare and contrast, and persuasive. All coding was on a scale of 0 ( low ) to 5 ( high ).

Content quality

• Content is not relevant.
• Some content is relevant, but simply repeats facts that were given.
• All content is relevant, but simply repeats facts that were given.
• Content is relevant and elaborates on given facts.
• Content is relevant and sophisticated, and qualifies, elaborates, and uses the information.

Organization quality

• Ideas are presented in a list and are confusing.
• Ideas are in sentences, but do not progress logically.
• Organization is logical, but has little to no framing (e.g., topic sentences).
• Some framing of ideas, as well as logical progression, is evident.
• A lot of good framing, as well as logical progression, is evident.

Inter-rater reliability was calculated separately for Grades 5 and 7. For fifth grade, three essays from each of the 10 students were rated separately by both researchers. The initial correlation between those ratings was .66. After discussing all ratings where the researchers differed by two or more points, the coding scheme was updated to take into account text features that both researchers had attended to, as is customary in linguistic coding research. Once ratings were adjusted based on the discussion, the correlation for fifth grade was re-computed to be .89. For seventh grade, the same procedures were used. After coding the 10 essays separately, the correlation between raters was .68. All differences of two or more points were discussed, and changes made in the coding scheme based on those discussions. After the changes from discussion in the coding schemes, the essays were recoded by each rater, as is customary in linguistic coding; the correlation of inter-rater reliability across coding schemes was then re-computed to be .88 for seventh grade. Once inter-rater reliability was established at the standard level in discourse coding (.80 or above) to be .89 for fifth grade and .88 for seventh grade, the first author completed all the coding within a brief time. At the time the data analyses were completed, both coders (the co-authors) reviewed the coding procedures for a randomly selected subsample and found almost complete agreement even though a new coefficient was not computed.

Number of words written

For each essay, the number of complete words was also counted. Misspelled words were counted as words, but neither incomplete nor scratched out words were counted in the totals.

Data Analyses

Pearson product–moment correlations ( r s) were computed for the content and organization ratings for each genre. ICCs were computed for content and organization ratings and number of words. Repeated measures ANOVA was used to test the differences in means across the three expository genres at each grade level.

Descriptive Statistics and Correlations—Grade 5

Table 1 presents the means, standard deviations, and ICC values for all measures across the three expository essays for Grade 5. Correlations of these measures across genre pairs, per Olinghouse et al. (2012) , were computed for Grade 5. For content quality, informative and compare/contrast essays were correlated .65, informative and persuasive essays were correlated .60, and compare/contrast and persuasive essays were correlated .55. For organization quality, informative and compare/contrast essays were correlated .65, informative and persuasive essays were correlated .56, and compare/contrast and persuasive essays were correlated .60. All correlations were significant at the p < .001 level. Squaring the correlations shows that participants shared only modest variance across the genres. Likewise, the high ICC values for these typically developing writers suggest that much of the variation between the genres was due to participant differences.

Descriptive Statistics and Correlations—Grade 7

Table 2 presents the means, standard deviations, and ICC values for all measures across the three expository essays for Grade 7. Correlations of these measures across genre pairs, per Olinghouse et al. (2012) , were also computed for Grade 7. For content quality, informative and compare/contrast essays were correlated .52, informative and persuasive essays were correlated .57, and compare/contrast and persuasive essays were correlated .67. For organization quality, informative and compare/contrast essays were correlated .56, informative and persuasive essays were correlated .56, and compare/contrast and persuasive essays were correlated .55. All correlations were significant at the p < .001 level. Squaring the correlations shows that participants shared only modest variance across the genres. Likewise, the high ICC values for these typically developing writers suggest that much of the variation between the genres was due to participant differences.

Comparing Three Genres for Fifth Graders on Multiple Outcome Measures

Repeated measures ANOVAs were performed for 110 fifth graders to examine mean differences between essay genres for each of three outcome measures: rating of content quality, rating of organization quality, and number of words written. Where Mauchley’s test was significant, indicating a violation of sphericity, Greenhouse-Geisser-adjusted F tests are reported. These ANOVA results, which are reported in Table 3 , demonstrate that at least one of the essay types significantly differed from the others for each outcome measure. Follow-up pairwise t tests were conducted using a Dunn–Sidak adjustment to see which essay types were significantly different from each other. Each model will be discussed in turn.

Note. df = degree of freedom.

Content quality ratings

Follow-up tests found a significant decrease in content ratings between the compare/contrast essay and the persuasive essay, as well as between the informative essay and persuasive essay ( p = .024 and p = .002, respectively). Consistently, content ratings were lower for persuasive essays even though they were written last after more practice in writing about the mountains. Trend contrasts for essay type showed that the change in content scores had significant linear components (as illustrated by the mean values in Table 1 ), with the contrast F test p value < .01. As expected, participants varied significantly from each other on content ratings, Var = 2.31, F (1, 109) = 1420.48, p < .001, ICC = .84.

Organization quality ratings

Follow-up t tests only found a significant difference in scores between the informative essay and the compare/contrast essay ( p = .006). Trend contrasts showed that the change in organization scores had significant linear and quadratic components, with contrast F test p value < .05. Ratings decreased between the informative essay and compare/contrast essays, and then increased between the compare/contrast essays and persuasive essays, as shown by the mean values presented in Table 3 . Understandably, organizational demands may be greater for compare/contrast than informative essays. Of interest, even though content ratings were lower for persuasive essays than compare/contrast essays, organizational ratings were higher for persuasive essays than compare/contrast essays. So the lower content ratings for persuasive essays cannot be attributed to their being written at the end of the series of essay genres. As expected, participants varied significantly from each other on organization ratings, Var = 2.95, F (1, 109) = 1087.08, p < .001, ICC = .85.

Number of words written (length)

Follow-up t tests found significant differences in the number of words written between each pair of essays (all p values < .01). Trend contrasts showed a significant linear and quadratic effect for number of words written across the essays, with both contrast F test p values < .001. Although the number of words written decreased between the informative essay to the compare/contrast essay ( M = 10.40), there was a large increase between the compare/contrast and the persuasive essays ( M = 16.17), which surpassed the mean number of words written in the informative essay, as shown in Table 3 . Of interest, this pattern of results paralleled those for the organizational ratings, but not the content ratings. As expected, participants varied significantly from each other on the number of words written, Var = 1000.62, F (1, 109) = 755.92, p < .001, ICC = .88.

Comparing Three Genres for Seventh Graders on Multiple Outcome Measures

Repeated measures ANOVAs were performed for 97 seventh graders to examine mean differences of the three kinds of essays on content quality rating, organization quality rating, and number of words written (length). Greenhouse-Geisser adjusted F tests are reported as needed, as in the fifth-grade analysis above. Results for these ANOVAs are reported in Table 4 .

Descriptives and Results for RM ANOVA Grade 7.

No significant effect of essay type was found on content ratings at Grade 7, in contrast to what was found at Grade 5. However, participants accounted for significant variance in content scores, Var = 1.82, F (1, 96) = 2520.20, p < .001, ICC = .84.

A significant effect was found for essay type on organization ratings, and a trend analysis found significant linear components ( p = .001). Follow-up t tests using a Dunn–Sidak adjustment found that the mean differences were only significant between the informative essays and persuasive essays. In contrast to the fifth graders, the seventh graders showed lower organizational ratings for persuasive than informative essays. As expected, participants accounted for significant variance in organization scores, Var = 1.71, F (1, 9) = 2779.04, p < .001, ICC = .80.

A significant effect was found for essay type on the number of words written. Trend analysis indicated significant linear and quadratic components to the trend of words written (both p values < .001). Follow-up t tests with a Dunn–Sidak adjustment found a significant decrease in words written between informative essays and compare/contrast essays ( M = 12.44), as well as a significant increase between the compare/contrast essays and persuasive essays ( M = 23.98), and the informative essays and persuasive essays ( M = 11.54), all p values < .001. Although the first two findings replicated those for fifth grade, the third pattern of results occurred only in the seventh grade. As expected, participants accounted for significant variance in the number of words written, Var = 1139.47, F (1, 96) = 1266.77, p < .001, ICC = .87.

First Tested Hypothesis

The first hypothesis was confirmed. Results for fifth and seventh graders are consistent with findings of Olinghouse et al. (2012) and Boscolo et al. (2012) , who have reported evidence for intra-individual differences across genres in developing writers during middle childhood and early childhood, respectively. These differences occur not only between narrative and expository writing ( Olinghouse et al., 2012 ) and within narrative writing ( Boscolo et al., 2012 ) but also across different genres of expository writing—informative, compare and contrast, and persuasive essays, as shown in the current study for fifth and seventh graders. These findings have important implications for high-stakes assessments of writing, classroom assessments given by teachers, and individual assessments given by psychologists and speech and language specialists because they demonstrate that multiple written compositions representative of different genres must be used to draw conclusions about a student’s written composing ability.

Second Tested Hypothesis

For fifth graders, this hypothesis was confirmed. Differences were found among the participants across the genres. However, for seventh graders, the hypothesis was only partly confirmed—for organization ratings but not content, and for length, one of the patterns for contrasts between essay genres for seventh graders was different from the fifth graders, although two were the same. Thus, the transition from upper elementary in fifth grade to middle of middle school in seventh grade in writing multiple essay genres is characterized by some constants and some variables.

Educational Applications

Of educational significance, the current findings show that not all expository essays are created equally—different types of expository essays are likely to produce different results for the same student (intra-individual differences) and different students (inter-individual differences). Specific kinds of individual differences depend, to some extent, on criteria employed to evaluate the quality of composing—content, organization, and length—and grade level. A single annual assessment of a single written composition may not be adequate to conclude whether students meet common core or other high-stakes standards in writing, or to capture an individual student’s ability to write different kinds of expository essays, or to create a plan to translate assessment findings into educational practice. Both high-stakes tests and individually administered psycho-metric tests should assess multiple grade-appropriate genres for determining composition ability/abilities. Both profiles for composing across genres and an overall score based on indicators of writing in multiple genres, similar to that used in assessing scholastic aptitude(s), would contribute to psychoeducational assessment of composing.

Clearly, future translation of research into educational practice should include development of assessment tools for writing that are evidence-based. Annual tests that are based only on a “pass–fail criterion” are not evidence-based. Currently, normed tests exist for assessing various aspects of handwriting, spelling, and sentence-level composing. Regrettably lacking are standardized, psychometric, normed measures of text level composing for a variety of text genres within the same instrument , so that relative strengths and weaknesses for specific genres as well as writing ability across genres can be identified with an instrument standardized on the same population. Traditional approaches to reliability of assessment attribute variation in performance to unreliability of the test instrument, but in the case of a process such as written composing, which is inherently generative ( Chomsky, 2006 ), the variation may be fundamental to the process being assessed. Given the generative nature of composing written language, which is fundamentally an open-ended process and challenging to assess in a standardized way, innovative approaches to assess composing for multiple genres and to link assessment findings to writing instruction in developmentally appropriate ways remain to be developed.

Moreover, the writing genres assessed with normed measures should reflect the kinds of composing required for school writing assessments. Although much writing for pleasure may involve narrative writing, narrative composing is not sufficient to complete the kinds of writing and integrated reading–writing required for successful completion of written assignments at school and for homework during middle childhood and adolescence. Hopefully, prior research on multiple genres reviewed in the introduction and the new findings reported in the current study will contribute to development of such standardized, normed assessment tools for multiple genres that have ecological validity for the kinds of writing students are expected to do at school.

In addition, writing portfolios might be used to collect and periodically review classroom writing assignments across the school year. Both first drafts and revisions can be included in the portfolios as well as extended writing that may be co-constructed with classmates and/or the teacher. Assessment tools might be developed for periodic review of the writing portfolios at specific grade levels. Such periodic reviews should include teachers, students, and parents.

Limitations and Future Directions

The topics chosen for each of the genres were constrained by a desire to keep the topics as constant as possible—the mountains familiar to the participating students in the study—and provide constant background knowledge to all participants before engaging in essay genre composing. Future research might investigate the interaction of topics and genres by comparing multiple genres on a variety of topics common to each. Also, the nature of the longitudinal assessment did not permit linking assessment results with classroom instruction other than sharing assessment results for normed measures (not researcher-designed measures) in an annual assessment report that parents were encouraged to share with schools to use as teachers found useful. Future research should address the dynamic interplay of assessment-instruction links throughout the school year at specific grade levels.

The current research on multiple genres was restricted to two time points in writing development and schooling—middle childhood during the upper elementary grades and early adolescence during middle school. Given both the constants and variations in essay writing observed between upper elementary and middle school, future research should explore development of composing multiple genres from P to 12 and beyond in postsecondary education and the world of work. Moreover, the current study involved a one-time assessment in a larger project, much as the annual testing linked to high-stakes standards involves a one-time assessment in a given school year. Future research on multiple genres of written composition should involve multiple assessments within a grade level and the relationships of assessment findings to ongoing writing instruction in the classroom—both designing it and evaluating responses to it.

Although the current study expanded the study of genres beyond the usual narrative/expository divide to three kinds of expository essays, not all possible or relevant genres, expository or otherwise, were investigated, which hopefully future assessment and instructional research will do. Consistent with the generative nature of writing genres, our research group continues to be amazed at the creativity of the genres observed in developing writers, even for the same written assignment (manuscripts in preparation). Despite the limitations of the current research and need for much future research on multiple genres of composing across development and schooling, the current study does provide converging evidence for the reported findings of Olinghouse and colleagues and Boscolo and colleagues. Hopefully, these and other relevant studies will inspire others—both practitioners and researchers—to approach writing assessment from the perspective of multiple genres in writing given the generativity of language for thought expression.
