A thesis statement declares what you believe and what you intend to prove. A good thesis statement makes the difference between a thoughtful research project and a simple retelling of facts.
A good tentative thesis will help you focus your search for information. But don't rush! You must do a lot of background reading before you know enough about a subject to identify key or essential questions. You may not know how you stand on an issue until you have examined the evidence. You will likely begin your research with a working, preliminary or tentative thesis which you will continue to refine until you are certain of where the evidence leads.
