This will allow for clarity and direction throughout the essay.

Although these genres have been criticized by some composition scholars, the Purdue OWL recognizes the wide spread use of these approaches and students’ need to understand and produce them.
In the first paragraph of an argument essay, students should set the context by reviewing the topic in a general way.
Next the author should explain why the topic is important (exigence) or why readers should care about the issue.
This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Do not introduce any new information into the conclusion; rather, synthesize the information presented in the body of the essay.
Restate why the topic is important, review the main points, and review your thesis.
