I much prefer to learn by doing. I prefer doing and reading over videos. Some video creators spend too much time getting to the point; for example, spending fifteen minutes discussing something they only needed three minutes for. A video isn’t like a book, where you can page past the boring stuff, and you can’t “skim” a video the way you can a book. If I skip ahead in a video, I don’t know if I’m missing some useful gem while skipping the fluff.
In your survey, did you also think about checking for Meyers-Briggs types to see if there’s a strong preference among different types? For example, the Meyers-Briggs typology would predict that sensor types prefer concrete, hands-on learning over conceptual material.
