When did this happen? I got my PhD in physics in 2008 and other than the introductory undergrad classes, all other classes (that I knew of, at least) were still taught using chalkboard/whiteboards.
And I agree with a sibling comment on this thread. The speed of information is ideal with live ‘writing/derivation’, as you can follow along at the teacher’s own pace and write each step yourself.
I used to do his for my own section classes I taught as a TA. I’d come in with a small post-it size note of starting points, and just work brought problems without referencing anything else. Kept it down to Earth, and I think (or hope) showed the students there’s nothing insanely hard here, just lots of small bite-sized steps.
