What is Expository Assignment Writing? Read This Post to Know More

Expository assignment writing has a number of different views to prove a point such as a problem and solution, comparison, descriptive, how-to, and cause and effect. The purpose of this type of writing is to explore all angles of the topic and provide evidence to the audience so that they can learn something new and useful.

The structure of this writing usually goes through three stages that most writing formats use such as introduction; Thesis, Body; Evidence, and the Conclusion; Restatement of the thesis with additional evidence.

Expository Assignment Writing

Problem and Solution

This type of pattern is mostly used on proving that change needs to happen or describing a problem. Depending on what the problem is, the writer needs to explain the inner workings about why the topic is a problem and convince the reader why it needs solving.

Once a problem is defined, the next step is finding the solution and explaining the solution through the body text of the assignment. This part can be fairly simple as there are many ways to solve a problem but there has to be evidence to support that it’d work.

In finding such evidence, it doesn’t have to be physical but can be theoretical thinking. The writer would need to have explored all options of solutions in order to refute any objections that may come up.


There are two ways to write in a comparison pattern for expository assignment writing which is Comparison and Contract. The contrast shows the difference between subjects and comparison shows the similarity of the subjects.

The subjects would be in the same category but different. For example, if the subject was vegetarians and meat-eaters. The similarity being diets and the contrast being how different the two are from the other.

Throughout this type of assignment writing, evidence has to be present therefore researching why these subjects are different or why they’re similar must come with evidential content.


This pattern uses sensory information to reach the point. By describing a place, subject, experience, or situation, the writer paints a picture in the reader’s mind.

This type of pattern is similar to writing a personal story and uses personal feelings to further convey deeper meanings.

While still having evidential facts on the mind, the writer shows the reader their point instead of writing in a black and white kind of way.


This type of pattern explains the how-to in starting something or supporting a cause.

It can be as simple as writing a how-to on becoming vegetarian or a how-to on lessening the effects of climate change.

This kind of pattern needs to be easy to read and follow along with. The reader should be engaged and analyzing the topic. The writer must use evidence or show proof of their experience with reaching their goal so that the reader knows it’s possible for them as well.

Cause and Effect

The last pattern looks toward the reasons/causes for why something is happening or why a situation is a way it is. The evidential effects are then discussed and the conclusion could either include a solution or a summary of the thesis clearly stating why something is happening and leaving it up to the reader to find the obvious solution.

By stating the cause of an effect, the reader can come to the conclusion that the effect would be lessened if the cause came to a halt.

Research is the key ingredient in reaching a valuable solution with this pattern as the writer must look at the relationships between all subjects remotely relating to the main point.

In Conclusion

Expository Assignment Writing, otherwise known as Expository Essay Writing, is the type of writing style that uses evidence, research and argumentive writing to reach the reader in a clear and concise way. The topic is usually presented to a specific audience who has some knowledge of the topic already. This type of writing is informative and uses an analytic method to reach the reader.

The types of patterns listed above can be mixed together but generally, one type of pattern is enough to reach the point.
