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.
If I need to write fast I can’t even read my handwriting. Currently teachers send us notes electronically which also gives us more time for discussion. Well, guess how we view the notes.
