A double perspective is offered on computer-assisted instruction (CAI): (1) a definition is provided, the role of a computerized component in an ESL curriculum is examined, and the potential of computerized learning in the ESL field is explored; and (2) the CAI program at Strayer College in Washington, D. C. is described. The definition proposed is the use of a computer in enhancing the learning and mastery of a specific skill. Because of CAI's versatility and provision for individualization, several advantages of this type of instruction are discovered: (1) errors can be analyzed and positive reinforcement given; (2) testing can become a learning process; and (3) it can provide almost unlimited opportunity for drill and practice. Almost any written material can be adapted for computer exercises using the drill and practice, tutorial, testing, dialogue, or simulation and gaming modes. The computer learning program at Strayer College is mainly employed in the drill and practice mode and is used along with classroom instruction. The other instructional modes are used as well and are described briefly. Several computer exercises are appended. (AMH)
