“…The acoustic quality of the instructor's voice, however, received below-average ratings for the replay. This result was a major motivation to enhance the audio recording quality in eChalk by the approaches described in 8 . Despite the shortcomings in audio quality, the overall quality of the system was clearly seen as positive, both in classroom teaching and in replay.…”

This article describes a software system that transforms an electronic whiteboard into a teaching tool simulating a traditional chalkboard. In addition to writing and drawings, the electronic chalkboard handles a wide range of multimedia enhancements. These may be used to enliven the lessons by visualization, allowing the system to surpass the didactic potentials of the traditional chalkboard. The system records all actions and provides both a live transmission and a replay of the lecture from the web. Systematic evaluations from regular use at two universities are presented.
