That was certainly my experience when going to university. They were phasing in digital classes of sorts, so pressured lecturers to use PowerPoint or similar. I recalled almost nothing from those lectures, as it was impossible to take notes and listen at the same time. And without taking notes I'd forget.

The blackboard ones though, with carefully prepared notes by the lecturer... I'd write it all down, and would hardly ever had to look at them again as it stuck right away. However, I did have to write it down.
