Writing a Good Expository Essay

When writing an expository essay, one must adhere to the norms and requirements expected of informative writing. The following steps can be used in the process of writing this type of essay;

First Step: Topic Selection, Brainstorming, and Research

Choosing the topic to write about is never always a walk in the park. The writer has to think through their topics. Usually, people tend to have a rough idea about a topic they come across, even with little information or knowledge about the topic. The mind will not draw blank and the rough idea may be based on something someone heard, read about or practices. Brainstorming can be achieved when one takes the initiative to sort out what they know through a number of techniques such as writing freely what immediately comes to the mind. This entails writing quickly, without stopping or editing things which immediately come to your mind about the topic in hand. Writing down the thoughts helps one be aware of what they already know, feel, think on the topic. One should remember that brainstorming exercise does not involve evaluation of ideas; however, it allows the writer to pour out all ideas and background knowledge they have on the topic. Evaluation and organization of the ideas only come later once they have been recorded on a paper.

After brainstorming, one will identify gaps in their knowledge on the topic, and this will direct him or her to conduct research to acquire more information or knowledge. Libraries or internet searches are awash with sources of information and knowledge. Books, journals, reports, conference papers and many other credible sources can be accessed.

One must exercise caution when looking for sources, especially on the internet. Not all websites or information are credible, reliable and reputable. Even when one gets the information they are looking for they must give credit to the authors, or else they risk committing an academic fraud known as plagiarism.

After conducting the research and obtaining the information needed, one should then re-organize their thoughts to evaluate whether they are clear on the topic.

Second Step: How to Write the Introduction

The introduction is the first paragraph of an essay that gives the audience the roadmap for deeper discussion. It introduces the reader to the topic in an interesting way and outlines the main ideas of the writer and also explains how the ideas will be presented in the main discussion or body of the essay.

There are three elements which make up the introduction; a hook, background information, and thesis statement. Expository essay examples contain a first sentence which is interesting and catches the attention of the reader. A hook sentence introduces the topic in an interesting way to make the reader to want to quench the thirst of reading the entire article. The background information should put into context the topic. It is a build up to the thesis statement. Thesis statement is usually put at the end of the introduction. It is very important because it informs the audience about the writer’s position about the topic and also brings out main ideas which will be discussed subsequently. A thesis statement has two main parts – a claim and the supporting information. A claim is a single sentence where the writer makes an assertion based on a generalization. It is debatable since it is not based on fact. Supporting information or details seeks to reinforce the claim made. Therefore, thesis statement combines a claim and supporting details into a single sentence towards the end of the introduction. The introduction of an expository essay sample would be;

Topic: Gun Control Policy by United States Federal Government

Introduction: That about 115,000 people are shot every year in the United States (according to The Brady Campaign To Prevent Gun Violence) calls for tighter gun control regulations in the country. In 2011 it was reported that in 100 people, there is an average of 88 guns. Indeed, the fear of loss of safety is real in America. Both the proponents and opponents of stricter gun control regulation present genuine concerns. Proponents argue that weaker regulations have caused a proliferation of firearms in the hands or civilization which in so many instances has resulted in may loss of lives due to misuse of the firearms. They are supported by the statistics. Opponents of tighter gun control regulation argue that chipping off their right to bear guns will make them unable to protect themselves and more insecure. Gun control policy is a complex and controversial issue in America, of which understanding requires a national stakeholder dialogue to find a solution to the fears and safety of the American public.

Third Step: How to Write the Body Paragraphs of the Essay

A look at any good expository essay example shows that the body is the most detailed part. It contains logical sentences which include supporting details and evidences. This section has three parts; a topic sentence (gives the main idea of the paragraph), supporting sentence (explains and develops the topic sentence. It includes specific evidence from sources which support the thesis) and concluding sentence (is a concluding thought which also helps to transition to a new paragraph). An example of expository essay body would for instance be:

Gun control policy in United States has been a battlefront which lobby groups have attempted to take control over. The National Rifle Association (NRA) in 2016 spent about $54 million on lobbying and on political advocacy – which included contributions to Trump’s campaigns. The NRA remains one of the most influential interest groups in the politics of America. However, recently Gun control groups have become more organized and vocal, and have increased on their expenditures. Some of these interests groups supported by wealthy individuals have sought to challenge the capability of NRA. A host of factors have threatened the dominance and influence of the NRA on gun control policy. First, is the decrease in the revenues of NRA over the past two years, particularly in 2017 due to reduction in membership. The mid-term 2018 elections also saw proponents of gun control Democrats win a number of key seats.

Fourth Step: How to Write the Conclusion or Summary

This is the final part of the essay. In most expository essay examples the conclusion has close semblance to the introduction. It emphasizes in summary form the main points of the essay. It concludes the essay by reviewing discussions from the body paragraphs giving the audience the final thought.

The conclusion is made of three parts; restatement of the thesis (is done at the beginning of the conclusion, though in a manner different from introduction), summary of main ideas (from each of the body paragraphs to remind the audience) and the final thought (this is the writers final thought, opinion, solution or prediction on the topic or issue. It should also be interesting in order to leave the reader with a strong impression). An expository essay sample would conclude in the following way;

Lack of stronger gun control policies in America has continued to cause many losses of lives each year. Furthermore, many citizens are able to easily acquire firearms. Intense lobbying for and against stricter gun control restrictions have been spearheaded by influential interest groups that also have sought to control America’s politics. The most influential of all has been the NRA. This paper focused on the reasons advanced by the proponents and opponents of tighter gun control mechanisms. Safety of the public is crucial to the development and growth of the country. It suffices to say that there is a need to find a middle ground in the wake of the grandstanding over Gun control policy.

The above steps are guides to ensure the writer observes what is required of an expository essay. However, the following tips will ensure that the essay is written in a correct way.

  1. Before writing, the writer must consider a topic which is not only writable but also researchable. Not all topics or issues qualify for explanation or description in an expository essay.
