My mathematics department (where I am employed as faculty) is considering requiring its Ph.D. students to take a two-semester course in pedagogy and educational theory. All of them also TA lower level math classes, so the proposal has some merit. I am trying to decide whether to support or oppose this proposal (or suggest modifications to it).
Although I am skeptical, I want to be open-minded. In departments that have adopted such requirements, what have been the positive and negative outcomes? Have students enjoyed such courses, and/or felt that they were useful? And has the quality of TA education been improved?
