Abstract
The present article describes a statistical synthesis of results from 48 comparative studies of an innovative method of college teaching, Postlethwait's Audio-Tutorial or A-T approach. The analysis showed that in general A-T instruction has a significant but small overall effect on student achievement in college courses, and it has no significant effect on student course evaluations or on course completions. Findings were similar for well-designed and less-well-designed studies included in this analysis, and they were also similar for studies carried out at different types of schools and in different subject areas. Results reported in journals, however, were more favorable to A-T than results found in dissertations and other unpublished reports.
