The following assignment will challenge both your research skills and your assessment capabilities. Based on Kuhn's The Structure of Scientific Revolutions , the intent is to get you to make reasonable inferences about the current state of an intellectual discipline based on only a scant amount of evidence. Though it would be impossible to render a definitive decision on such a large question with limited information, it is possible to make good guesses with the basic map Kuhn offers.
Textbooks are usually easy to spot because of their basic titles.
If you have your own textbook from one of these courses, by all means use that. If not, you should be able to locate one by doing just a little legwork in the library. Try to stick with a good publisher, although sometimes good textbook publishers differ from good scholarly publishers. Look at the bibliography or notes to see if the most cited works are in books or articles. Give a rough estimate of the percentage of work in scholarly journals versus books.
