This is the first of two Classroom Presenter demos offered during the 2005 Microsoft Research Faculty Summit. Classroom Presenter is a Tablet PC–based classroom interaction system built on the ConferenceXP research platform. Classroom Presenter supports active learning in the classroom by distributing exercises to students on slides, which the students answer on their tablets and send back to the instructor. The instructor can review the slides to evaluate student understanding and selectively display the slides on the public display to incorporate student work into class discussion. This demo will give audience members an opportunity to play the role of the students in a technology-supported classroom.
