Web 2.0 in the classroom

I’ve taken the plunge and have decided to focus my doctoral study on the barriers to using Web 2.0 tools in the classroom.  Because it’s a relatively new field, I’ll need help from you out there.  Please send me the names of any articles, journals, books, etc. that you think will help me in my research.

In a few days I’ll post more about what I’m thinking and where I want to head. 

 But for now, I have a paper due Sunday, people, and I need 3 references!
