Abstract. We present a prototype sketch-based physics tutoring system that combines mathematical sketching, an interaction paradigm that supports construction of dynamic illustrations using the association of handwritten mathematical expressions with drawings to govern animation behavior, and a custom physics engine. We highlight key features of our core system that focus on correcting approximately drawn sketches and maintaining the correspondence between imprecise handwritten drawings and precise mathematical specifications. We describe the behavior and design of the system in detail and finally, present two example scenarios illustrating its possible uses in an educational setting.
