A generalizable architecture for building intelligent tutoring systems

Summary form only given. HYDRIVE (HYDRaulics Interactive Video Experience) is an intelligent tutoring system incorporating assessment as part of the tutoring process. HYDRIVE departs from typical intelligent tutoring systems in that its underlying architecture is domain independent. The domain that is presently supported by HYDRIVE is troubleshooting for the hydraulics supported systems of an Air Force F-15 fighter aircraft. HYDRIVE addresses both system-specific and system-independent skills. Several novel approaches to intelligent tutoring underlie the rationale for HYDRIVE. The reasoning component of the system makes extensive use of a hierarchical knowledge representation. Reasoning within the system is accomplished using a logic-based approach and is linked to a highly interactive interface using multimedia.<
