On Tuesday, October 6th, I will be leading a professional development workshop at my school on Wikis. One of the first things I will be doing with the teachers is having them view a 5-slide presentation on Good, Bad, and Ugly uses of wikis. I would appreciate feedback from those of you who are using wikis:
1. How have you seen wikis used effectively?
2. What are common but ineffective uses of wikis?
3. What are some downright bad uses of wikis?
