There were several surprises. We had special concern about the appeal of such a method for foreign graduate students and concern with their ability to be involved in such a discussion. In fact, it turned out that many foreign graduate students found the cases a useful window on American university culture, and many had deep ideas about teaching that were useful to all. We thought that the cases would work the same with all levels of graduate students, but we found that many beginning graduate students did not have the experience base to discuss all cases, since they had not given any thought to the teaching aspect of their designated profession. Fortunately[50], it also turned out that this could be addressed by having more experienced peers, such as a head TA or two, in the case discussion. Most crucially, we learned that leading a case study discussion requires different skills from lecturing on the part of the faculty leader and that there is a learning curve to leading a successful case study discussion.
