The addition of video capabilities to portable media playing devices has engendered a broader definition of the term podcast to include video files. Current research designs on podcast use in education are neglectful of the considerations of cognitive load on student learning. Podcasting is the process by which multimedia learning objects (MLOs) are delivered via Really Simple Syndication (RSS). This review identifies connections between the technology, pedagogy, and student learning that should be emphasized in podcast research. The importance of using podcasts is discussed, and the current types and uses of podcasting are identified. Areas where the potential of podcasts have not been realized, such as RSS usage, are also identified. Cognitive load theory and the implications of podcast and learner attributes on the design principles for MLOs are discussed. Finally, conclusions of the current review and suggestions for future studies are presented. (Contains 1 table.)
