Moving from Topic to Thesis

It is important to remember that a narrow topic is not the same thing as a thesis statement. Unlike a topic, a thesis makes a claim of fact, provides a claim of value, or makes a recommendation about a topic under consideration. 

For example, your narrowed topic might be "the underemphasis on foreign language in U.S. secondary schools." A focused thesis statement making a claim about this topic might read, "U.S. secondary schools should require elementary students to take at least one course in a foreign language sometime during the 4th through 6th grades."

Transforming a workable topic into a possible thesis is really just a continuation of the narrowing process, with an emphasis on what you want to say about your topic. In this way, it is much like the "hypothesis" stage of the scientific method. You arrive at a thesis by attempting to make a statement about the topic you have chosen.

Developing a Working Thesis

There are two components of a working thesis. The first is, quite simply, your topic; and the second is your tentative statement about your topic. For example, if my narrowed topic is

"Rising property taxes in small towns in the Rocky Mountain region..."

I might add the following statement about [italics] that topic:

"...cause longtime residents and landowners in those towns not to be able to keep their property."

As I begin whatever research is necessary to support this thesis, I might find that I can't make this much of a claim. Or I might find that there are complexities that I hadn't considered. As I uncover new information about my topic, I will want to alter my working thesis accordingly, until it is workable and supportable.
