"Stump the Professor"

I have been playing with the idea of playing games with students in online courses, mostly influenced by recently seeing an episode of "Are you smarter than a 5th grader?" online. When I think about those types of games -- Jeopardy, Millionaire, and so on -- I think that it is the questions that make the games interesting. And, that the folks who have the most fun and learn the most are those who construct the questions. It is hard to write a good question. If you can write a good question...that's everything. So, I've been having students -- as individuals or in teams -- compete to develop a great question that can stump me and the rest of the class. Then we have a race to see who can answer it first -- me or them (usually in teams). They usually win, and that's very cool.
