Absolutely smartphones should be banned, at least during lessons, and at best during the whole time in the school, recess, etc.
Giving a child a dumb-phone in an environment where everybody else uses a smartphone doesn't work. If smarphones are not banned then _all_ will end up with a smartphone, and socialisation difficulties, etc...
This is a case where individual freedoms end up in collective damage. Maybe I'm an outlier here but I'd ban all kinds of social media all the time.
They are failing spectacularly on that front anyways. You don't learn useful skills by being handed a remotely administered tablet or Chromebook, which is what schools provide.
Actually </s> they were learnig vital skills like Agile Sprint management! (I don't know if they ever physically met for standup meeetings)
1. Educational is not vocational training. Schools should give kids skills and a foundation, not teach them how to use particular technology.
2. Not all jobs require much knowledge of how to use technology.
2. True, though less true over time. Even in the non-tech jobs you're now constantly using technology. In the trades, you need to know how to operate a CNC machine. As a nurse, you're operating medical devices that are getting more and more powered by technology.
But at the same time, I think banning smartphones is perfectly fine because you can still use computers and stuff. It's not like they're going back to quills and ink.
Smartphones fry your attention span and enable bullying. And if parents want to have emergency contact, you can always have a simple mobile phone with texting/calling.
