As you gather information, search catalogs and databases, and read and evaluate sources, you will probably refine your research question and change your hypothesis significantly. Only after you have explored your hypothesis, tested it, and sharpened it by reading, writing, and talking with others does it become a working thesis.
For David Craig’s research essay, see Chapter 52.
David Craig, the student whose hypothesis appears in 15b, did quite a bit of research on messaging language, youth literacy, and the possible connection between the two. The more he read, the more he felt that the hypothesis suggested by his discussion with instructors—that messaging had contributed to a decline in youth literacy—did not hold up. Thus, he shifted his attention to the positive effects of messaging on communication skills and developed the following working thesis: “Although some educators criticize messaging, it may aid literacy by encouraging young people to use words and to write—even if messaging requires a different kind of writing.”
In doing your own research, you may find that your interest shifts, that a whole line of inquiry is unproductive, or that your hypothesis is simply wrong. The process of research pushes you to learn more about your hypothesis and to make it more precise.
