In the past two decades, as new capabilities for video communication have emerged, their use in educational contexts has steadily increased. Initially located in higher education, the use of videoconferencing for a broad range of learning purposes is now established in many schools. Although a considerable body of literature exists that describes the "experience" of videoconferencing using traditional pedagogies, much less has been published on the contextual factors that lead to effective learning outcomes and innovative uses of videoconferencing. The purpose of this review is to establish a baseline for researchers interested in the area. In focusing on educational uses in both higher education and mainstream schooling, the review examines the affordances and barriers to effective teaching and learning, with what are increasingly robust and easy-to-use technologies. The paper concludes with a call for further research into the more innovative possibilities of videoconferencing.
