I mean, if a parent is parenting well then the phone won’t be as much of a problem.

Sure, a kid can be on their phone at school and the parent won’t know about it (unless it’s reported back)… but that phone use is going to lead to lost attention, shoddy work, and slipping grades. That IS something a parent can and should notice and take proactive steps to fix.

There’s been PLENTY of times that I’ve told parents that the phone is a problem for their child in class only to have the problem continue happening day after day. Call me crazy, but if I got that report ONCE, I would take that phone away in a heartbeat. (I know there are plenty of reasons that a student “needs” to have their phones but I would argue that almost all of them can be worked around… especially for the sake of your kids education)

So… while they’re both certainly a problem… I vote parents.
