Generative, Knowledge-based Approaches for Rapid

"Proposed here is an effort to develop a generative, knowledge-based instructional development and delivery system, Jenny, for simulation-based training. Courseware development with Jenny involves (a) populating a knowledge base representing the structureof subject-matter knowledge and (b) creating simulation-based and other instructional materials that are associated with the knowledge base. At delivery time, Jenny creates and manages instructional interactions that are responsive to a student model. Themodel is a representation for the knowledge base that is continuously updated based on student performance. Jenny will initially focus on procedure training, but will be designed to conform to a broader standards for interoperability of knowledge bases,instructional procedures, and instructional materials. In addition, the simulation-based delivery system will provide for instructional delivery through a variety of interfaces including the World Wide Web and virtual-reality systems. Jenny's approach willmake it possible to fundamentally restructure the division of labor in the design, development, maintenance, and delivery of courseware. The result of this restructuring will be dramatic decreases in the costs and cycle times of instructional developmentand maintenance, and dramatic increases in the richness and responsiveness of instructional interactions offered to students. The goals are to (1) make it easy for subject-matter expe
