The thesis statement is the most important part of your essay because it is the central argument on which everything else is built.
The thesis statement is not a statement of fact, which is not debatable. However, it is also not an opinion either. Instead, in a thesis statement, you are taking a position that you have arrived at after conducting research. That position is debatable and argumentative because valid reasons can be presented to support and oppose it.
Take, for example, this thesis:
Oil sands development in Alberta should be curtailed.
This is a decent thesis statement because it takes a position, because it is specific about what aspect of the oil industry will be discussed, and because there is a geographic focus. A little more detail (an explanation of “why”) would make this stronger. For example:
Oil sands development in Alberta should be curtailed due to its harmful effects on wildlife and the environment.
This thesis statement is stronger because it elaborates on why oil sands development should be limited. We get a fuller sense of what the essay will discuss.
Once you have a thesis statement for your Critical Essay that takes a position, submit it here for feedback.
Your thesis statement will be marked WEAK/DEVELOPING/SUCCESSFUL. Use the feedback from your instructor to revise your thesis and ensure it presents a strong argument.
