I see a lot of possibilities for Wikis. The educational Wikis were reader friendly. They showed you exactly what you thought you would see. The ones that were not educational had all sorts of other stuff attached: advertisement, gadgets, etc. I did not spend much time looking at them. They did not interest me.
I see many possibilities for a Wiki. I have always enjoyed creating my own website, so I can think of many ideas.
There was one that a group of 4th graders did on the book Tuck Everlasting and I know we could do something like that with our students in all different subjects. Again, this might be something we could collaborate on with our pen pals in Chicago. Any other ideas?
