114 college students enrolled in an introductory course in special education were randomly assigned to a conventional instruction (CI) or a computer assisted instruction (CAI) version of the course. The CAI group received all instruction by CAI; the CI group received instruction in the conventional lecture-discussion mode. The CAI students obtained significantly higher criterion test scores than the CI students. Also, the CAI students completed the 3 credit course in an average of 12 hours less time.
