I created a Wiki for my government class and my students were assigned groups to teach certain amendments from the Bill of Rights. I spent several periods trying to figure out how to link the pages --one of the pitfalls of Wiki Jason says--you have to know a bit of what you want before you start. Anyway--I have 3 classes with 5 groups in each--so I have 15 pages going. They have loved this assignment. Each group has three amendments--so they have done a lot of collaboration. They have loaded up video, glogsters, powerpoints, links to games and sites. The glogster was a problem. I paid for the 50 student membership--but my old glogster wasn't edu. I had to contact them--and get it migrated over. (2 days). We then went to the lab and the students didn't type in the edu before glogster--so they were firewalled and couldn't get in. We have had all sorts of fun learning how to embed, save or link everything.
I will find out tomorrow how successful things were/are. I like the ability to check out the student work--most did work directly on the Wiki--but I found a few groups used google docs.
I will definately use this again--they loved the lab time (I have set aside 6 days for lab work--and two weeks for this activity. They have enough on the Wiki that I could get a grade now and just make use of what they have to teach it if I wanted--but I want them to have the fun of doing the lesson. They took most snags in stride. I don't know that my 7th EP would be as easy a group as the 8th Honors.
