The prezi is a general overview of thesis statement. I begin with the definition of a thesis statement, then relate the thesis statement to a road map and discuss the two parts of the thesis: topic and comment. The prezi also has examples of do's and don'ts of thesis statement writing.
I typically use this presentation after students have written a rough draft. To write their rough draft, I have them use their topic as the thesis statement, or--gasp!--I let them use "I am going to analyze." I have found thesis statement writing gives them writer's block, so I do it once they see what they are going to write about.
