MetiVis for videos and explanations
Watching isn't the same
as learning.
A video can explain something perfectly and still lose you on one idea you never learned.
Rewatching the same ten minutes
doesn't fix the missing thing underneath them.
The block is usually smaller than the subject.A missing prerequisite. A word nobody defined. One jump the speaker thought was obvious.
Don't measure learning by minutes watched.
Ask whether the idea became usable.
