Recently I visited Richard Anderson's classroom at the University of Washington and watched how he used Tablet PCs to teach his computer science class. It is really cool. Students can send him notes, post their thoughts, and interact with him, via their Tablet PCs. This technology came out of Microsoft Research's ConferenceXP Project and the UW Classroom Presenter has a site which has more details and downloads too. The first minute of the video shows off his classroom then we start an interview with Richard and a few others who use or helped build the Classroom Presenter.
