College Prof here. It’s nice to see you working to help your son through college. I’d just tell you, some professors, myself included, have started to ban devices in the classrooms. The temptation of social media and games is far too high. If he’s saying he prefers to use paper notes, that’s probably a good thing. I can see the advantage of using one, but again, since they multitask, the temptation is far too high, this has been a problem that’s gotten much worse since lockdown. I used to allow at least computers in class, but given my students’ falling grades, I realized I wasn’t helping them out by being slack.
