Effectiveness of computer-based education in elementary schools

A meta-analysis of 32 comparative studies showed that computer-based education has generally had positive effects on the achievement of elementary school pupils. These effects have been different, however, for programs of off-line computer-managed instruction (CMI) and for interactive computer-assisted instruction (CAI). The average effect in 28 studies of CAI programs was an increase in pupil achievement scores of 0.47 standard deviations, or from the 50th to the 68th percentile. The average effect in four studies of CMI programs, however, was an increase in scores of only 0.07 standard deviations. Study features were not significantly related to study outcomes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25814/1/0000377.pd
