Belshazzar: A simple tool for creating and publishing voice-annotated drawings on the web

A tool called Belshazzar was developed for creating and publishing voice-annotated drawings on the web. The tool allows an instructor to dynamically capture the problem solving process in action with a voice annotated representation. Using one click the process can be replayed, and with a second click published to the Web as a Flash™ movie. The tool can also be used for assessment and research. It is stated that if students solve a selected task using the Belshazzar system, a teacher or researcher would have a rich media file that captures the essence of a student's problem solving capabilities.
