A meta‐analysis of the effectiveness of telecourses in distance education

Abstract

Abstract This study used meta‐analytic procedures to examine experimental research literature about the use of telecourses in adult and higher education. Weighted effect size analysis procedures were used. The study included experiments that used video and either one‐way or two‐way audio. The purpose of this study was to review evidence concerning the effectiveness of telecourses. The instructional features that impacted learner achievement were type of interaction during the broadcast, type of course, and type of remote site. Two‐way interaction was found to be the best method of interaction between learners and the instructor. Most of the studies failed to provide information about their learner attrition rate, thereby casting a shadow on the results.
