This report describing the use of operations research techniques to determine which courseware packages or what microcomputer systems best address varied instructional objectives focuses on the MICROPIK model, a highly structured evaluation technique for making such complex instructional decisions. MICROPIK is a multiple alternatives model (MAA) whose overall goal is to formulate an evaluation and decision-making procedure and to model or simulate this evaluation framework as closely as possible, involving the school environment's established needs. An overview of the technical workings of the modeling framework and its performance of the evaluative comparison and final selection of alternative functions is followed by an explanation of the primary and secondary goals of the model. Alternatives evaluated by the modeling framework are discussed, as well as the criteria necessary to evaluate and compare these alternatives. Additional topics covered include constraints, the execution, results, and the general utility of such a model together with common advantages and potential pitfalls. (LMM)
