(Note: full study PDF is on researchgate)

I would take this with a giant grain of salt:

1.) N is in the hundreds of students, all with similar backgrounds - likely a highly specific population. It may not generalize well.

2.) The videos were pretty short: 3-15 minutes long.

3.) The overall effect size is pretty miniscule - it would make little practical difference.

4.) The video topics were roman history and real estate appraisals.

It will be interesting to see if this generalizes (to longer durations, more technical topics, more diverse population, etc.), but given the above I wouldn't change any personal habits based on this study.
