Representing Mathematical Concepts: Sketchcast

Sketchcast is a web-based tool that allows a user to record a virtual sketch with or without their voice, then save or share their sketch with others. This tool would allow a student or teacher to diagram a problem, much as they would on a chalkboard. Students could turn in their worked-out solutions to problems for analysis by the instructor, who could easily diagnose misconceptions by reviewing the step-by-step production of the student's solution.
