The problem examined by this research is tracking, with low update rates, on ground vehicles. Tracking solely by statistical prediction is inadequate for infrequently observed targets that exhibit non-deterministic behavior. The approach used here is to assume non-deterministic but rationale behavior will govern the targets. The method used to track is then to estimate the rationale behind the tracking by modeling that rationale using sophisticated knowledge modeling techniques. This report contains the additional results of the second year of research on moving target tracking of non-deterministic targets using low update rates for the observations. The first years effort centered on building the structure needed for tracking. The original intent was that the basic structure was ready to receive the knowledge needed for tracking at the end of the first year and that knowledge would be installed during the second year. A lack of data sets made that impossible, so the second year, in the end, focused on technical improvements in the system.

This paper presents initial work on an adaptive trainer for basic helicopter flight skills. The work was performed by Bevilacqua Research Corporation, Inc., the University of Alabama in Huntsville, and Cognitive and Behavioral Systems. The project was performed for the U. S. Army Research Institute of the Behavioral and Social Sciences, Ft. Rucker Field Unit. In this initial phase of the project, the project team: 1) created initial student conceptual models, 2) created initial instructor conceptual models, 3) identified methods to dynamically update and evaluate student models, 4) identified methods to modify instructional models in response to student behavior, and 5) developed a top-level adaptive trainer design. The conceptual models were designed using conceptual graph structures as described by Sowa (1984) and were applied as an adaptive trainer would to an example instructional sequence to prove the utility of the employed methodology.preparedness have not taken advantage of these new
