Four main kinds of videos on the edX platform (2014):
- Recorded classroom lecture
- Instructor's talking head
- Khan-style digital tablet drawing (popularized by Khan Academy)
- PowerPoint slideshow
Main findings and corresponding recommendations:
1. Shorter videos are much more engaging. Engagement drops sharply after 6 minutes
2. Videos that intersperse an instructor’s talking head with PowerPoint slides are more engaging than showing only slides
3. Videos produced with a more personal feel could be more engaging than high-fidelity studio recordings
4. Khan-style tablet drawing tutorials are more engaging than PowerPoint slides or code screencasts
5. Even high-quality prerecorded classroom lectures are not as engaging when chopped up into short segments for a MOOC
6. Videos where instructors speak fairly fast and with high enthusiasm are more engaging
7. Students engage differently with lecture and tutorial videos
