This document discusses the design and development of computer-assisted instruction (CAI) materials. It outlines a 6-phase process: 1) needs analysis, 2) design, 3) development, 4) implementation, 5) evaluation, and 6) documentation. The design phase involves storyboarding content, defining learning objectives, and determining the instructional strategy. Development includes creating computer presentations and interactive exercises. The implementation phase entails training teachers and students to use the CAI materials.
