Considerations and procedures for applying Performance-Structure Oriented computer-assisted instruction (CAI) are described in terms of a general diagram of the necessary elements in a CAI system. The fundamental objective is to lead the student to develop his own cognitive structures that will serve him for generating the surface structure of tasks. The instructional system must accomplish this by generating and scheduling a suitable instructional sequence for each student. The developmental steps, from job task structure analyses to computer programs, are described. Higher-level programing languages and general purpose programs are two categories of techniques for generalizing these procedures. Examples of instructional flowcharts, programer's flowcharts, and data encoding procedures used in the development of the radar intercept officer's trainer are presented to illustrate keypoints in the developmental steps.
