The availability of compact, low-cost computer systems provides a means of assisting classroom teachers in the performance of their duties. Computer-assisted instruction (CAI) and computer-managed instruction (CMI) are two applications of computer technology with which school administrators should become familiar. CAI is a teaching medium in which students respond to computer displays. The ability of computers to interact with students distinguishes CAI from most instructional media. The computer may provide corrective feedback or present new information based on the student's response. The forms of interactive CAI include drill, practice, tutorial programs, problem-solving, instructional simulation, and testing. CMI provides information to the teacher that assists in the management of learning activities, and facilitates the processing of student information. CMI systems alleviate the burdens of recordkeeping and thereby enhance decision-making. School administrators should provide the appropriate leadership and support for the use of CAI and CMI in the educational process. (JEH)
