"To humanize online teaching is to create a situation where strangers can meet by the campfire, discuss what is important to them, and depart with the sense of connection, despite the darkness, and a feeling of community. It is that feeling of authenticity."
This meta-analysis of the effects of video on learning found that adding video to existing teaching led to strong learning benefits. Videos may provide students with control over their level of cognitive load, they allow authentic demonstrations of skills, and they enable teaching staff to edit according to multimedia learning principles. Videos were more effective for teaching skills than transmitting knowledge.
