A thesis map is similar to a table of contents for a dissertation or large project, although instead of simply listing the chapters, it often shows the relationship between them. In a typical thesis map diagram, the thesis statement or specific research topic is stated at the top. From there, arrows are drawn to several categories that the thesis breaks down into. Each of these categories can be further divided into subgroups.
Some universities require their PhD candidates to construct a thesis map because it shows the student's thought process in developing the project. While a table of contents can tell a reader where to find information in a project, the map diagram shows connectivity with other groups of information or experiments, revealing where other pertinent information can be found, as well as how the author came to arrive at that point logically. For example, in a research project, a thesis map may show data collection leading to data analysis, resulting in discussions and conclusions.
The essay thesis map is meant to help students organize their ideas before starting an academic essay. Much like the dissertation thesis map, it begins with the thesis statement. From there it branches into "points" or "arguments" that will be presented in the paper. Each argument is further subdivided into supporting evidence. Each point will likely take up an entire paragraph, in which the supporting evidence is given. For example, the argument "Macbeth was subject to fate" must give examples of when fate controlled his life.
A valuable essay thesis map must start with a strong thesis. The thesis is one sentence that defines an argument within the context of the essay's subject. It should be specific and set up the arguments found later in the paper. The arguments that are subdivisions of the thesis in the map should outline the reasons for the assertion expressed in the thesis. The components of the map, with the exception of the thesis, do not need to be in complete sentences, since they are only an organizational tool. The map, when completed, should help the writer return to the thesis statement at the top after organizing his ideas and revise it before writing the essay.
