What is an argumentative essay?
The argumentative essay is a genre of writing that requires the student to investigate a topic; collect, generate, and evaluate evidence; and establish a position on the topic in a concise manner.
Please note: Some confusion may occur between the argumentative essay and the expository essay. These two genres are similar, but the argumentative essay differs from the expository essay in the amount of pre-writing (invention) and research involved. 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. 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. Argumentative assignments may also require empirical research where the student collects data through interviews, surveys, observations, or experiments. Detailed research allows the student to learn about the topic and to understand different points of view regarding the topic so that she/he may choose a position and support it with the evidence collected during research. Regardless of the amount or type of research involved, argumentative essays must establish a clear thesis and follow sound reasoning.
