Learning Algorithms with an Electronic Chalkboard over the Web

, .. Abstract. This paper describes a system for the animation of algorithms on an electronic chalkboard. The instructor teaching an algorithm can enter data directly through a drawingthe algorithm then makes use of this data, for exampIe numbers, or the image of a graph. The drawing becomes alive. The result is a more natural way of teaching and starting algorithmic animations. The paper also describeshow to couple a sign and handwritingrecognitionengine with the animation system. The lecturer can then write programs using her own handwriting, and the prograrnsruns. All animations can be enriched with sound and explanationsfrom the lecturer and can be posted to the Web.
