If I'm going to get anything out of a lecture, I need to be able to effectively take notes on it. To do that, I need to be able to parse an hierarchy of concepts, aka an outline. You know: I. Blah A. Sub-blah 1 B. Sub-blah 2 II. Foobar A. Sub-foobar 1 etc. If I can't determine how to organize my notes, then it's not really a lecture. It's just someone talking haphazardly about something they know way more about than I do. If they're introducing any concepts that I'm not already familiar with, I'll be lost pretty quickly. This isn't a huge ask is it? I don't need an explicit outline written on the board for me. All I need is a little recognizable organization, and I can figure it out from there. Otherwise, I'm usually better served by reading a good textbook. The hardest class I ever had in school wasn't hard because of the material, it was hard because there was no textbook and the lectures were extremely disorganized, just random ideas that weren't linked together in any obvious way. There's no need for that.
