A meta-study has found that the use of pre-recorded video can lead to "small improvements" in learning and replacing existing content with videos can result in "strong" learning benefits.
The work, published by the American Educational Research Association (AERA), was undertaken by a team of researchers from Australian Catholic University (ACU) and the University of Queensland. They analyzed 105 prior studies that covered a pool sample of 7,776 students. Those studies had used randomized controlled trials to compare the effectiveness of videos (both recorded lectures and highly edited clips with audio and visual elements) against other forms of instruction, including face-to-face lectures, tutorials or assigned readings. What the project didn't include were those studies where video usage couldn't be isolated from other variables, such as in the adoption of "flipped" classrooms.
Videos were found to be more effective for teaching skills than for transmitting knowledge (an increase of five points versus two points). According to the research, this may be because video provides "a different, more authentic perspective." For instance, the report noted, while learning about the history of feminism in India may show no difference in impact between sitting in class or viewing a video, video has the advantage for other topics, such as learning a medical procedure or a new skill.
