A Comparison Study of the Learning Effectiveness of
Computer Aided Instruction vs. Classroom Lecture
by Rick Mills


This study investigated the effectiveness of using Computer Aided Instruction (CAI) for skills training in the workplace. Manufacturing employees received electrical training using CAI or classroom lecture. Learning, satisfaction, and cost of each method were measured. CAI was found as effective as classroom for factual topics, but not as effective for theoretical topics. CAI learners expressed higher satisfaction in the self-pacing of instruction, but lower satisfaction in logistics of environment and instructor access. CAI learning required less time for factual topics, but more time overall and for theoretical topics. Implications for implementation of CAI in industry include selecting topics carefully, using CAI to communicate abstract concepts and animations of hidden processes, allowing learner self-pacing, providing instructor access, and recovering high initial development costs with repeated use.
