I’m a nodder. Consequently I’m also shit at taking notes but engage in the class instead and remember it more from pictures in my mind i.e. a visual learner. I also ask questions. It works for me, at least in subjects I’m interested in - at least up to MSc level. If it’s something I’m not interested in, even notes won’t help! In one ear and out the other.
When teaching/presenting, knowing that people pick things up in different ways, I offer both a visual presentation and a paper version with key points I’m talking about so the note-takers can write on something (even if they were just going to fill up a notebook anyway!
I nod to indicate listening so much that I’ll do it when I’m not even been seen >m< it happens over voice chat w my friends and sometimes even with videos
