Compares the effects of peer tutoring and computer-based instruction on student achievement and motivation through a meta-analysis of research. Cost effectiveness is also investigated via ratios which combine the effects of the intervention with estimates of implementation costs, and an appendix includes reviews of 10 cost-effectiveness research…

Describes results of a meta-analysis that was performed to synthesize existing research on the effects of computer programing on cognitive outcomes. Effect size is used to evaluate studies that used experimental and control groups to assess the relationship between computer programing and cognitive skills, and outcome measures are discussed. (79…

Describes a study that examined the impact of computer-assisted instruction developed in the United States on the reading and math performance of students in Grenada. Results were compared with students receiving conventional instruction for high and low ability students and for gender differences. (Contains seven references.) (LRW)
