Group studying -- not groupwork -- was massively encouraged by many of my humanities/liberal arts profs and made a big difference to what I can only describe as... our sense of belonging in the course/program🧐

I am wondering now about whether the discipline/content/field of study affects prof (or student) behaviors/expectations/framings.

(At the same time, many profs would also make note of absences and ask those present to let them know if they'd be willing to copy their notes for absent classmates. No references to distributed cognition, but it was understood
to be good collegial behavior.)

Long before smartphones/light laptops, a professor observed to my class that recording someone without telling them is poor form. When I had students with documented accommodations, they would tell me in office hours and we'd sort it out. What's the conventional wisdom/etiquette/prescribed way now?
