Abstract
In this research, we investigated whether online discussions can significantly benefit students’ learning in online courses. We designed an experiment by dividing 129 students who enrolled in four fully online “Introduction to Microeconomics” courses taught by the same instructor into four groups (one control group and three experimental groups). We adopted econometric analysis to investigate the issue. Our empirical evidence demonstrated that online discussions can significantly benefit students’ exam performance in online courses only when instructors are effectively engaged in discussions. Instructors who do not effectively engage in online discussions had a less than significant effect on students’ exam performance even when peer-responses were required. On the other hand, the effect was positive and significant when instructors effectively engaged but the level of significance was weak (at the 10% level of significance) and began with a later exam (Exam 4, out of a total of five exams) rather than the first exam or earlier. Detailed discussions about these phenomena are offered as are several possible reasons for these findings. We recommend significantly increasing weights for online discussions in the final course grade and including exam questions that directly reflect online discussion questions (including serious participation in discussions and requiring that students provide answers to instructors’ follow-up questions). These additions would significantly benefit students’ learning in online courses.
期刊介绍：
E-Learning and Digital Media is a peer-reviewed international journal directed towards the study and research of e-learning in its diverse aspects: pedagogical, curricular, sociological, economic, philosophical and political. This journal explores the ways that different disciplines and alternative approaches can shed light on the study of technically mediated education. Working at the intersection of theoretical psychology, sociology, history, politics and philosophy it poses new questions and offers new answers for research and practice related to digital technologies in education. The change of the title of the journal in 2010 from E-Learning to E-Learning and Digital Media is expressive of this new and emphatically interdisciplinary orientation, and also reflects the fact that technologically-mediated education needs to be located within the political economy and informational ecology of changing mediatic forms.
