VModel uses a "construction kit" metaphor, enabling students to express their knowledge in an ever-expanding collection of principles and processes, thus emphasizing the underlying unity and systematic structure of scientific knowledge. VModel provides multiple levels of computer support, ranging from simple drawing and publishing tools to a coach that uses qualitative simulation to help students see whether or not their model supports their prediction. As many urban schools have outdated or minimal computer equipment, we have taken care to keep VModel lightweight, so that it does not require the latest computer hardware to run. VModel has been used in a number of experiments in Chicago Public School classrooms, with encouraging results.
