What makes effective instructional videos? Which elements contribute to successful learning objectives and retained knowledge?
Takeaways from the Research:
- High production values may not increase learning
- Length of video greatly affects attention, aka “The Six Minute Rule.”
- Inclusion of an instructor’s visage makes videos more engaging.
- Nearly anything is more engaging than a Powerpoint with voiceover.
- Prerecorded lectures can’t be improved by chunking.
- Incorporating interactive questions embedded in video may improve student’s performance as well as satisfy student’s preference.
- Use an inverted pyramid model to address important content first and ancillary content later.
