The document discusses the role of computers in education through computer-assisted instruction (CAI). CAI can integrate various types of educational software into lessons, including tutorial programs, simulations, instructional games, and problem-solving software. It also describes multimedia encyclopedias and electronic books. The teacher's role is to ensure students have the needed skills for computer activities, select learning objectives, plan structured activities, and evaluate student achievement. Students receive information, understand instructions, and apply knowledge during computer learning. CAI provides a learning environment, delivers instruction, reinforces learning, and provides feedback.
