A Meta-Analysis of the Effectiveness of Teaching and Learning With Technology on Student Outcomes

In 2002, NCREL commissioned a meta-analysis by Hersh Waxman, Michael Connell, and Jon Gray to study the effects of teaching and learning with technology on student outcomes. That paper calculated 138 effect sizes using statistical data from 20 research studies representing a combined sample of approximately 4,400 students. The mean of the study-weighted effect sizes averaging across all outcomes was .30 (p < .05), with a 95-percent confidence interval.

In 2003, Hersh Waxman, Meng-Fen Lin, and Georgette Michko extended the study to include data from 42 studies representing a combined sample of approximately 7000 students. This study is presented below. The mean of the study-weighted effect sizes averaging across all outcomes was .410 (p < .001), with a 95-percent confidence interval (CI) of .175 to .644.
