I was not a great student but at one point in college I realized that I wasn't listening while taking notes. I was just mindlessly copying everything exactly as was written on the white board missing out on what my teachers said.
I stopped taking notes at this point and started paying attention instead. My grades improved. This might not work for everyone but something to try if you struggle retaining lecture content even as you take a bunch of notes.
In a physics or maths class that seems impossible unless the prof is teaching directly from distributed notes or the text book. Some of the better classes I had were those where the prof just gave out their notes and we could focus on what was said rather than writing it out, in that case if you zone out it's your fault.
Actually I was a Math major the biggest thing for me is 1. notes can be very cryptic after the class without the verbal context. A lot of course also have that advantage where the teacher would provide notes afterwards so yeah focusing in on what was said was the highest value.
It was my fault that I zoned out, that's why I had to find a way to avoid it.
Funny, for me it's the opposite. Can't remember it if I don't write it down. I don't have to read it afterwards, I just remember what it was by remembering writing it.
I've found that taking notes in cursive helps my listening comprehension, for whatever it's worth. But it makes it harder to use my notes as a reference later.
yes, ive had similar experiences, and thinking back on it, why take notes when you can just record the lecture and play it back later.... better to engage in the lecture, since thats why we are there in the first place!
