Twitter in the Classroom Update

It took two weeks for tech services to install a twitter widget on the podium computer in my classroom. That widget, Twitterlicious, seems to be quite unstable and wigs out every ten minutes. The client I use on my Mac, Twitterific, is much more stable. We're trying to find a better widget. Simply projecting the Twitter webpage takes up too much room on the screen. I need that space for other projection.
The students seem quite enthusiastic about this new way of communicating. There are four active twitterers, but all the students pay attention. This does reduce anonymity, but they don't seem to care. They also happen to be four of the more active students in the class. Some students enjoy bringing their laptops to class, while others know they can use their text message on the cell phone to add a comment. only 50 to 60% of the comments are pertinent.
However, that is not the point. What Twitter does is to even out the balance of control over the direction of the conversation in the classroom. Students feel they can redirect the topic thru a "tweet." I look at the thread from time to time, but usually because of some reaction among the students.
It is still tool early to evaluate whether this technique improves learning. When asked, students who don't twitter in class still defend having it there. They feel it gives them greater ownership of the class experience. This week, I'll begin trying a full classroom "capture" (video, audio and screen projection) where the twitter steam is less important. It will however enable me to demonstrate the technique to others when the course is over.
