摘要：The use of media within online university courses has been shown to aid the learning process with the delivery of information through various formats. However, issues that inhibit learning have been found when media are used inappropriately. Based on an examination of extant media research, this study arranges common media delivery problems into five main categories: pace, intelligibility, quality, media diversity, and congruence. Students taking online courses were asked to comment on the media used in their classes. Each of their comments was paired with one of the five categories with justification provided for the categorizations. Through analysis of these learner comments, this study examines the extent to which media delivery problems occur among a specific sample of online university learners in South Korea. The underlying pedagogy that explains the issues caused by inadequate delivery of media is also discussed, followed by recommended solutions that can address such pedagogical concerns. The results not only highlight existing solutions to these types of media problems but also build on them by suggesting other techniques in which media can be delivered so that the overall online learning experience may be enhanced.
