The design, development, and evaluation of an integrated Computer-Directed Training Subsystem (CDTS) for the Air Force Phase II Base Level System is described in this report. The development and evaluation of a course to train computer operators of the Air Force Phase II Base Level System under CDTS control is also described. Detailed test results for validation of the computer operator course and Formal Qualification testing of the CDTS are presented. Conclusions and recommendations with respect to the current CDTS recommendations for additional capabilities and for further implications are discussed. Appendices contain flow diagrams, a computer operator's course outline, samples of data collection forms, test scores, and testing results. (Author/JY)
