Classroom 2.0 strikes me as a giant communal blog. As with blogs, separating the wheat from the chaff takes so much time that it’s hard for me to see the value. Perhaps if you’re a brand new teacher with little support in your own school… Personally, I’d rather collaborate face-to-face with my coworkers or else share specific ideas with folks teaching roughly the same courses as I in a similarly competitive independent school. Wading through the mass of information and chatter is just not worth the time.
Similarly, while I’m glad that some teachers are finding an educational use for Twitter, I have no interest in supporting Twitter itself. It represents a lot that I dislike about the new forms of communication that are so trendy now.
