I only managed one class like that and only near the end of my undergraduate career. Both earlier in ugrad and in grad school I was way too busy barely staying afloat to be so meticulous about my education.
For engineering classes, I would rather invest the entire time in the class to focus, ask questions, and read the content from the textbooks if it's standard stuff covered there. The ideal scenario is doing it before class, but even going through textbooks on the same day and creating notes based on them works fine for me. During my pre-undergrad days while preparing for entrance exams, my teachers would ask everyone to just listen to the whole topic while they used to explain on the whiteboard, and only at the very end, after the board was fully covered, would they give everyone 5–10 minutes to jot down the content in their notebooks. I really think that really balances all the classroom learning, but I have never experienced the same type of teaching philosophy elsewhere since then.
I also think that a particular type of learning style can't work across subjects. There is no one-size-fits-all. You can't study history the same way you do mathematics. Physics is very different from chemistry, and computer science is definitely different. A lot of universities (anything outside the top 10) in my country really got CS education all wrong. I see kids writing code in their notebooks. Mugging up random information. It's really jarring.
I started using Org Roam a bit over half a year ago. My policy with deciding what to store in it is: "is there a chance I will want to remember this later?" If yes, I write it down, and link it to something relevant, which allows me to find it later from the backlinks on that relevant note. I thought I had pretty good memory (I still think it isn't bad for a normal human) but I have been surprised fairly often that some tidbit of information that I want is neatly available as an atomic note, and I don't even remember writing it.
Btw this is university for you in France. Maybe we are good as a nation because everything before uni is actually good, and people who are good actually don’t go to uni but to grandes ecoles ? (Equivalent of ivy leagues)
The one thing worth writing down was exam hints.
I wish I had had YouTube back in the day, or at least video recordings of lectures that one could pause and rewind to portions that weren’t understand on the first pass.
But this is a skill that takes time to cultivate. Writing down what you hear and then rewriting your notes later does accomplish the same task, and it gives you more time to do it.
The advice is to understand, and consider questions while making notes. He has a section on when to ask questions in class.
The very next line after the one you quoted explain why he errs towards the former, but it does not say you should not concentrate, you should not try to understand, and you should not ask questions.
Theres not enough time to do all 3 of those, pick 2
I found this to be an ibcredibly effective learning technique
I always always erred on the latter. I was definitely in the minority. It took me ages to work out why nobody else ever asked questions (or challenged errors).
They were just writing stuff down to process later. I have never understood it, it seems so obviously like a wasted opportunity. At that point why go to class at all, you could just get sent notes!
