It's not just about making notes. It's what students do with them.
For example, it's quite common for some students to make lots of mindmaps or write their notes up in neat and file them away and then in their head tick it off that they've "done" their studying.
In reality what they should be doing is taking class notes, ensuring they've got them in an format they can revise from, then actively condensing the notes down to smaller formats (Eg knowledge grids at the end of topics / key flashcards / glossaries etc) and then using them as a study tool to learn that knowledge. Eg look cover write check, or review a topic and then look back at previous work and improve a response they've done previously, or look at the questions they lost marks and have another go to ensure they get full marks and so on.
As I mentioned earlier, I'd also be expecting an A level student to be doing independent study beyond the course (eg relevant podcasts / reading around the subject etc).
I think the "odd worksheet" comment is a little flippant too as there's nothing inherently wrong with worksheets. A well designed worksheet is an entirely valid thing to do.
Typical homework that I would set my A Level classes would include:
- watch a lecture / talk and make notes ready to discuss
- read a chapter of a novel and bring notes to the lesson
- technical exercises worksheets
- group presentation prep
- essay responses / essay plans
I typically set an hour a week of formal homework with the expectation that at A Level they should be using their initiative on private study. I also outline that expectation at the start of the year.
