Expository essays are often used for in-class writing exercises or tests, such as the GED or GRE.
Argumentative essay assignments generally call for extensive research of literature or previously published material.
Rather than explaining how these differing opinions are wrong outright, students should note how opinions that do not align with their thesis might not be well informed or how they might be out of date.
The argumentative essay requires well-researched, accurate, detailed, and current information to support the thesis statement and consider other points of view.
Each paragraph should be limited to the discussion of one general idea.
This will allow for clarity and direction throughout the essay.
The argumentative essay is commonly assigned as a capstone or final project in first year writing or advanced composition courses and involves lengthy, detailed research.
Expository essays involve less research and are shorter in length.
Some paragraphs will directly support the thesis statement with evidence collected during research.
It is also important to explain how and why the evidence supports the thesis (warrant).
