State Your Thesis
American academic essays are usually "thesis-driven." This means that you as the writer must explain the main point of your essay at the start. A thesis statement is a sentence or two that
(1) shows the purpose of the essay
(2) indicates the basic components of the essay
(3) offers the unique perspective of the writer
The thesis-driven essay may be different from non-American writing forms, in which the thesis is often implied, delayed, or delivered at the end of the essay. Consider the thesis statement a concise version of the entire essay, which usually appears in the introductory section of an essay.
Here’s an example of a thesis for an informative essay:
The experiment failed because of the presence of helium in the vat; the helium tainted the purity of the environment and caused the data to be irrevocably skewed.
**Notice that this thesis is short but reveals the most important ideas.**
Here’s an example of a thesis for an argument essay:
Purdue University should offer more scholarships to international students because they have a greater desire to succeed in college, tend to work harder, and graduate more quickly and with greater frequency than American students.
