Intelligent Tutoring System Approach to Adaptive Instructional Systems

摘要

Report developed under a Small Business Innovation Research Program 99.2 contract for topic OSD-99-O4. Training programs provide students with deliberately selected learning experiences, so they can acquire and retain knowledge and skills. Intelligent Tutoring Systems (ITSs) are computer-based training systems that mimic human instructors to provide automated, one-on-one instruction. Most ITSs developed so far have applied a limited set of strategies for adapting instruction to differences among individual students. During this Phase I SBIR project, we developed a generic model of adaptive instructional systems that is designed to be broadly applicable across a wide range of training domains. We then applied this generic model as a framework for describing how AIS capabilities could be added to the Intelligent Flight Trainer (I,F,T), a helicopter training simulator deployed at Ft. Rucker, Alabama. Finally, we developed a limited, proof-of-concept software prototype to illustrate elements of this model. The generic AIS model appears plausible, feasible, and useful, and the software prototype provides additional encouragement.
