The use of video has become commonplace in education today. Educators are engaging students with video communication technology more frequently than ever before, given COVID-19. However, questions remain on how instructors use video as a communication and teaching tool in online and blended courses. The purpose of this literature review was to synthesize research on the use of video as a teaching tool in online and blended courses. A systematic approach was used to identify 64 peer-reviewed studies published from 2010 to 2020. A qualitative synthesis of the studies resulted in four themes: delivering video lectures, fostering discussions with video, using video assessments and feedback, and creating video check-ins. Each theme and related research are discussed in the article. Gaps in the literature are identified and recommendations are made for future research.
