Abstract

This article describes a system that produces web based learning modules as a by‐product of regular classroom teaching. The lecturer uses a pen sensitive display in place of the traditional chalkboard. In addition to drawings, the electronic chalkboard handles a range of multimedia elements from the Internet. The system records all actions and provides both a live transmission and a replay of the lecture from the web. Remote students follow the lecture looking at the dynamic board content and listening to the recorded voice of the instructor. Several use cases of the system as well as a systematic evaluation in two universities are presented.
