The effect of teacher presence in videos on intrinsic cognitive loads and academic achievements

Abstract

With the rapid development of information technologies, video-mediated learning has been widely used in education and studied in academia. Whether and how a teacher should be present in a video has drawn the attention of researchers. Via a mixed design involving two teaching experiments and a semi-structured interview, this study concluded that videos with teacher presence could significantly improve academic achievements and increase intrinsic cognitive loads compared with those without teacher presence and that videos with teachers’ intermittent presence could significantly improve academic achievements and increase intrinsic cognitive loads compared with those with continuous teachers’ presence. Future research could explore intrinsic cognitive loads and academic achievements in video-mediated learning via multimodal and interdisciplinary methods.
