Abstract : GUIDON is an intelligent computer-aided instructional program for teaching diagnosis, such as medical diagnosis. The program is general. Without reprogramming, the program can discuss with a student any diagnostic problem that it can solve on its own. Moreover, by substituting problem solving knowledge from other domains, the program can immediately discuss problems in those domains. This power derives from the use of Artificial Intelligence methods for representing both subject material and knowledge about how to teach. These are represented independently, so the teaching knowledge is general. There are teaching rules and procedures for: determining what the student knows, responding to his partial solution, providing hints, and opportunistically interrupting to test his understanding. Experience with GUIDON reveals the importance of separating out casual and strategic knowledge in order to explain diagnostic rules and to teach a reasoning approach. These lessons are now guiding the development of new representations for teaching. (Author)
