Wiki about Wikis-Gettting the Wow

In checking out weblogged links, I realized that there are many ways a wiki can be used. I looked at the sample education wikis. It seems like a great way to keep parents and students up-to-date and involved. I particularly liked the wiki that Mrs. Huff's class has created. On the wiki the students were asked to write a summary of a book they were reading. By creating the wiki, the students were able to modify what their classmates had written. This sounds like a great way to get even the most resistant student involved. It also encourages them to do the reading so that they can contribute to the wiki. If I were working with older students, I think this would be a great way to get the students writing. I am still thinking of a good way to incorporate all this new technology I am learning into my second grade class. What type of technology could I use to wow my students?
