This document discusses the advantages and disadvantages of computer-assisted instruction (CAI). It defines CAI as instruction or remediation presented using a computer. CAI is interactive, involving two-way communication between the learner and computer. Advantages of CAI include flexibility for students to work at their own pace, immediate feedback, helpful graphics, and variety added to courses. However, disadvantages include needing access to a properly equipped computer, lack of computer skills for some students, potential physical problems from overuse, costly educational software, and lack of human interaction compared to in-person instruction.
