I personally think that responsible smartphone use should be learned and practiced, rather than outright banning them.
I think this shows that adults are terribly addicted to their devices and think if they can't stop using them, children won't either. They certainly can't teach how to use phones responsibly if they can't do it themselves. Unfortunately for children the result is an outright ban.
How to teach a bullyer responsible smartphone use ? 😑
In my opinion, the whole school system needs a serious update.
But that will never happen because the function of the school is not to learn.
