I run a wiki for three of my classes. The first wiki is my oldest (I started it last year as a 1.0) and contains papers written by my senior students in college English. Be warned: some of the papers are works in progress!

The second wiki is one I run with my Virtual Worlds course. This one was begun in September and hosts journals written by the students as well as links to various articles they've read so far. Be sure to check out the textures they've created!

And the third wiki is one I created for my regular-ed English 10 class. The students keep their journals online here and I post information about the class here. The pages are spare at this point because it's so new.

I'd love your feedback!
