I teach CS in the US and I have gone back to pencil-on-paper quizzes for my classes. I allow one page of hand-written notes and given them a quiz review beforehand where I essentially tell them what's going to be on the quiz.

My intent isn't to trick anybody with hard questions, but rather to force the knowledge through their head out through their hand, then back through their eyes and through their hand again.

Next semester I'm doing in-person paper readings, where the first 20 minutes of the class are reading a paper I print out and hand to them, we discuss the paper in class, then they submit their annotated papers to me for a participation grade.

An irony of the AI era.
