Training in decision-making skills directly contributes to the combat readiness of Battle Staff Officers. More affordable, accessible, and effective training technologies are required to supplement the Command Post Exercises currently in use. This is the final report for a 3-year research and development (R&D) effort aimed toward development of such technologies. The R&D problem was viewed from the perspective of Instructional Systems Development (ISD) as one of defining instructional content and strategy. The analysis, design, and development phases of an ISD process were completed for a specific, representative decision-making task performed by Fighter Duty Officers of an Air Support Operations Center (ASOC). The project resulted in definition of a generic instructional strategy for practice of a class of decision-making tasks, and two computer-based systems called KEATS and SuperKEATS. KEATS, developed in Smalltalk to run on PC/AT compatibles, supports the acquisition of decision task knowledge that is used as instructional content. SuperKEATS, developed in KEE to run on a Sun 3/60 workstation, provides a practice environment for decision-making skills, with a full range of natural and artificial feedback. The limited evaluations performed yielded generally positive results. Further evaluations and continued development are recommended. Eleven figures and 13 tables illustrate the discussion.
