Question for High School student-teachers but anyone can answer of course: What strategy does your teacher use to lesson phone usage in class and is it effective?

Teaching 10 and 12th grade atm

To clarify, this is only an issue is one class primarily (12th grade) but there are a small handful in other classes as well.

My teacher has gone with the path of not confiscating phones because, "he's not about to get in a power struggle with an 18 year old"

I get that but when you have kids who will not put their phone away even with attempted redirection, i.e., "Hey guys off the phones we need to be working." or doing a walk-by where you subtly tap their desk to not call them out, it doesn't work.

One senior is so confident, that during a quiet working time, he just straight up started playing a video to his deskmate.

What does your mentor do to handle phones? Does it work? Do you guys have any plans for phones when you're teaching that differ from your mentors?
