Thanks to the folks at pbwiki.com for their help on the use of a wiki in the classroom. Also, Karl Fisch is an amazing resource for those of us trying new things in the classroom. After trying multiple ways to use this tool in a classroom, I was amazed at how fast the students adapted towards their use. The wiki allows the students to put together information in new ways and allows them to express themselves through the material that we are studying.
