A quick shout out to Ms. Joslyn Hemingway at Kent City Middle School. She is using a wiki with her Science classes to explore endangered species. (She used Wikispaces by the way.) Students in different hour classes are grouped together and have to gather data on a specific endangered species. Students use the wiki space to collaborate with each other and post information for the project. I happened to find out about it because my daughter is in Ms. Hemingway's class. Check it out here. Nicely done!
Now that you know what a wiki is, how a wiki works, and how a wiki can be used in class, it is time to experiment a little. Go ahead and try setting up your own wiki. Come on, you know you want to. You will be the envy of all the other teachers, right? There are a lot of wiki sites out there such as PBwiki (now PBworks) , Wikispaces (designed for educators), Wet Paint, and others.
Below is a movie on how Wetpaint Wikis work.
Pretty good, huh? Free too! Give it a try. Good luck!
