Visualization in Educational Computer Modeling

This paper describes recent research on the design and use of visual models and simulations in science education. The focus of the work has been the development and use of a variety of model development tools and applications to demonstrate the power and instructional benefits of visualization methods. Modeling applications were made in biology, chemistry, mathematics, and physics. The models incorporate graphic interfaces designed to enable easy interaction by students without the need for a deep understanding of computers. Work is described with two distinctly different kinds of visual modeling systems: a generic environment for science simulations (Explorer Science), and a universal visual programming language (Function Machines). In classroom trials of these programs, high school students were successfully introduced to the use of model-based inquiry in problem investigations.
