This review used Glass’ (1976) meta-analytic techniques to integrate findings from 59 independent evaluations of computer-based college teaching. The meta-analysis showed that computer-based instruction made small but significant contributions to the course achievement of college students and also produced positive, but again small, effects on the attitudes of students toward instruction and toward the subject matter they were studying. Computer-assisted instruction also reduced substantially the amount of time needed for instruction. In general, the meta-analysis found little relationship between study findings and design features of the experiments, settings for the studies, or manner and date of publication of the findings.
