What is a wiki?

Well, as I see it a wiki is a shared space that can be quickly and easily edited by a specific group of people.  It has tons of uses for the classroom and allows students to take ownership of their learning since they can post what they know about a subject.   

3 Wikis I liked...

http://salutetoseuss.wikispaces.com/ - A salute to Dr. Seuss - I really liked it because it was a great source of information that came from many different sources, and of course, who doesn't love Dr. Seuss!  

http://allaboutmath.wikispaces.com/ - Good math resource site - who doesn't need a place to question and be questioned about math.  I do wish it were more about content and less text based though.  It did give me good ideas on setting up a good math wiki.

http://goapes.wikispaces.com/ - This was an "all about apes" wiki and I loved all that info and the presentation of this wiki.  I think my students would really enjoy its content.
