Presented here are several techniques for design and development of computer-based adventure games for science education. Among the issues addressed are how subject matter maps to content, generative techniques for problem-solving practice, use of visualization, mechanisms for instructional support, and approaches to game development.

Computer programs that can tutor, discuss subject matter with students, and diagnose student errors will profoundly affect educational practice. C omputers play many education al roles in today's schools. Drill-and-practice programs let stu dents exercise with more efficiency and less pain than older manual meth ods. Tools such as word processors have… (More)

Production rules are a popular representation for encoding heuristic knowledge in programs for scientific and medical problem solving. However, experience with one of these programs, MYCIN, indicates that the representation has serious limitations: people other than the original rule authors find it difflcuit to modify the rule set, and the rules are… (More)
through 14 March 1982.' The goal of the project was to cfcvelop methods for representing teaching and problem-solving knowledge in computer-based tutorial systems. One focus of the work was formulation of principles for managing a case method tutorial dialogue; the other major focus was investigation of the use of a production rule representation for the… (More)
NEfMYCIN 1s a medical consultation system in which MYClFTs knowledge base is reorganized and extended for use in GUIOON, a teaching program. The new system constitutes a psychological model for doing diagnosis, designed to provide a basis for interpreting student behavior and teaching diagnostic strategy. The model separates out kinds of knowledge that are… (More)
A poorly designed knowledge base can be as cryptic as an arbitrary program and just as difficult to maintain. Representing control knowledge abstractly, separately from domain facts and relations, makes the design more transparent and explainable. A body of abstract control knowledge provides a generic framework for constructing knowledge bases for related… (More)
