Two important elements of a method of designing instructional alternatives (MODIA) are comprehensively discussed in this paper. The "Questionnaire for Stating General Policy" is briefly reviewed to reveal how goals, student population variations, and operations must be accommodated before specifying instructional strategies. The actual strategy specifications are constructed through DISTAF (Determining Instructional Strategies for Training in the Air Force), a computer directed logic tree that assists in planning the instructional methodology. DISTAF has been designed for use with either a simple manual that presents strategies or a complex computer program that enables the planner to use up to 57 different teaching strategies. The computerized tree allows the planner to take account of many different levels of subject matter difficulty and student abilities. DISTAF presents the planner with a variety of choices during the development of a workable strategy. It can categorize students into tracks, choose types of examinations and learning experiences, and enable the planner to construct detailed strategies in 10 to 30 minutes. (MC)
