Knowledge-based support for learning about physical devices is a classical problem in research on intelligent tutoring systems (ITS). The large amount of knowledge engineering needed, however, presents a major diiculty in constructing ITS's for learning how devices work. Many knowledge-based design systems, on the other hand, already contain libraries of(More)
Explanation is an important issue in building computer-based interactive design environments in which a human designer and a knowledge system may cooperatively solve a design problem. We consider the two related problems of explaining the system's reasoning and the design generated by the system. In particular, we analyze the content of explanations of(More)
