There are a number of different and subtle issues with running an intensive workshop. There is the issue of how to manage groups and the interaction between groups. On the content side, there is the issue of making a worksheet that isn't too frustrating, but also challenging enough to encourage collaboration. There are also questions of balance: groupwork vs. individual work (including quizzes) vs. lecturing. And the general issue of workshop pacing is a subtle one as well. (Eric Hsu, 1-1-96)
