[Air-L] Educational uses of Facebook

Hi, I have a number of students interested in researching the educational uses of Facebook. They are interested both in informal, creative, outside-the-classroom uses by students, as well as the way teachers are including Facebook in their courses. They are interested in both K-12 and post-secondary uses of Facebook. I've pointed them to dana boyd's work, but I'm not aware of much else. Can anyone point me to a bibliography or some key resources? Thanks! Chris
