I don't think primary school kids should have laptops outside of a computer room, it just seems really unnecessary.
When I was in primary school we had a computer room and if we brought phones we had to leave them with our teacher (I didn't have a phone until year 9 though - if I needed one before that I borrowed one of my sibling's for the day).
At my primary school for the last few years they've had their own ipads which stayed at school during terms, but they could take them home over holidays and keep them at the end of grade 6. They were locked up in the classroom though, the kids didn't have access to them unless they were being used and the apps on them were controlled by the school so I think that's fine.
I don't think primary school kids should have phones on them during the day (except maybe grade 5/6 - when they're old enough that they might need to communicate with parents during the day). I don't see any benefit to them having them, if something happens to a little kid they should be telling their teacher not calling home.
I do think that laptops are a good resource - they make it way easier to share files, for example, without having to worry about who doesn't have a hard copy because they're sick, and who's lost theirs, etc. I wish teachers were better at stopping people from using them when they shouldn't be though. At my old high school we had iPads in year 7 & 8 (who knows why, they were fairly useless
) but they weren't controlled at all (which was a good thing because we bought them, not like primary school). We spent every math lesson in year 8 playing a class game of flappy golf though so they definitely weren't being used responsibly.
Also in primary school I don't think they should be typing, lots of kids will type at home (in games or whatever) but most won't be practising their handwriting.
I don't think phones should be banned (except in younger years) as they can be useful, although mostly for taking photos. I also use mine for writing down homework/reminders, I'm way more likely to see it there. At my school we can also use it for other things (although my school's a bit unorthodox), we have a thing called teams (which is on phones and laptops) and there's a chat section and so if we have a room change or whatever we can see it on there rather than having to turn laptops on. I've also called teachers during class, and had teachers call me during class. Most of the time I misuse my phone privileges to browse AN though haha.
So yeah, that was a rambling post. Overall I guess I think that it shouldn't be banned but it should be controlled better than what it is. Heavily restricted in primary school, and more relaxed in high school. I do think that
when people are allowed to use their devices should be better controlled though (which is obviously hard given teachers have 1000 other things to do). I think it should be more flexible though. If people work better on their laptop, they should use their laptop. If they work better on paper, they should use paper. I really hate being forced to type something that I want to hand write.
