Cardlo-Vascular Laboratory Construction Kit This project is an experiment in teaching scientific principles and methods by a design approach. Using a flexible simulation environment-a lab construction kit-for the cardio-vasculars ystem,t he student is presentedw ith a system design problem that must be solved by an understanding of the function and structure of the componentsa nd their interacting behaviors. The kit, called Heart Works, implementsa ll componentsa s object-oriented programming constructs. The simulation is highly reactive and usesa direct manipulation, graphic animation interface. Finally, as a form of knowledge-based scientific visualization, Heart Works is capable of explaining its own behavior in terms of qualitative causal hydraulic principles. Extensive empirical research has been done on the effectiveness of both the interface and the automated explanation. The system is implemented in Allegro Common Lisp on the Macintosh II. Support for this project comes from FIPSE, U. S. Dept. of Education (Sarah Douglas, Nils Peterson and Daniel Udovic, coprincipal investigators),a nd from equipment donations and grants from Apple Computer and the National Science Foundation.
