This study attempted to identify the differences in cost-effectiveness analysis methods in order to select the most appropriate one as a decision-assisting aid for instructional management. The study is organized to explore and identify what cost-effectiveness methods are being used, identify and examine the differences among these methods in an analytical framework, and determine the criteria to be used in selecting the most appropriate cost-effectiveness method for instructional decisionmaking. The study results suggest that cost-effectiveness analysis provides answers by a systematic process that is reproducible as well as accessible to critical examination. It is believed that the use of instructional cost-effectiveness analysis will enhance the possibility that a decision will result in the selection of the best alternative. (Author/DN)
