This meta-analysis compared the academic achievement of students in grades six through twelve who received either traditional instruction or traditional instruction supplemented with computer-assisted instruction (CAI) across eight curricular areas. From the forty-two conclusions, an overall mean effect size of 0.209 was calculated, indicating that, on average, students receiving traditional instruction supplemented with CAI attained higher academic achievement than did 58.2 percent of those receiving only traditional instruction.
