To develop guidelines for the optimum use of computerized training systems in the Army, data related to computer based training were analyzed, including the results of a feasibility study and the results of comparative studies on student achievement, attrition, and attitudes. Three issues were addressed: (1) the effectiveness of computer based education (CBI) versus conventional instructional methods; (2) the comparison of two computer systems (IBM 1500 and PLATO IV); and (3) identification of problems unique to CBI. This report includes a review of relevant literature, background information on the study, a description of research methodology, and a summary of recommendations. (EMH)
