I'm curious if you or the parent have any suggestions for a problem I've been thinking about. I've been building a search engine for standalone lectures (https://www.findlectures.com https://www.findlectures.com). For me, the ideal outcome of being introduced to a new concept is that an idea sticks in my head for a while and won't let go, and I'd like to help people replicate that experience. Are there ways that you could track something that gets at whether this happens for people, or is this so qualitative that the best option is to interview users?

That's tricky and I don't have any great advice. If you could find some tangible piece of knowledge associated with each video, then have a quiz after some time, that might help. Or introduce some kind of spaced repetition. Alternatively, if you make the video categorization about what the viewer is interested in learning (that is, make the interface drive people to see videos based on what they want to learn, rather than having a hierarchical organization), then you can ask them later "did you learn X?" with some other survey like questions.
