Experiences with a tablet PC based lecture presentation system in computer science courses

ABSTRACT

Computer science instructors frequently teach using slides displayed with a computer and a data projector. This has many advantages, e.g., ability to present prepared materials and ease of switching the display to a development environment during mid-presentation. However, existing computer-based presentation systems severely limit flexibility in delivery, hindering instructors' extemporaneous adaptation of their presentations to match their audiences. One major limitation of computer-based systems is lack of support for high-quality handwriting over slides, as with overhead projectors and other manual presentation systems. We developed and deployed Classroom Presenter, a Tablet PC-based presentation system that (1) combines the advantages of existing computer-based and manual presentation systems and (2) builds on these systems, introducing novel affordances. Classroom Presenter has been used in 25 Computer Science courses at three universities. In this paper we describe the system, summarize results from its deployment, and detail several novel uses of the system by instructors in computer science courses.
