Honestly, get the tech out of classrooms. A few 8 bit machines that can run LOGO are far more genuinely educational than all the gunk they have today.
You're spot on with classrooms not needing tech though. They add complications and distractions on top of an already difficult task.
They almost let us play RuneScape (something something medieval history?) until they saw me firebolt a rat and declared it unacceptably violent.
I visited my old school once, a few years after graduating, and was startled to see many people on their laptops in the hallways. I guess they had become required. I had graduated right around the time smartphones came out, and we didn't have laptops either. (You'd see a laptop at school occasionally but it was a rare sight.)
I'm glad the fanciest thing I had was a TI-84, because it got me to spend most of my time socializing, which I think was pretty good for my development.
Was pretty impactful for my education, just not in the intended way
I then let a teacher use it because he was frustrated half of his search results would get blocked. From there, it spread like wildfire. Eventually they blocked it and from then on the IT guy would give me a side eye whenever we crossed paths.
Anyways, I can only imagine the clever ways kids get around things now. If it’s not per device, all a kid would need is a mobile hotspot to be king.
I decided to sidestep the whole game and run my own proxy at home. I didn't have enough bandwidth for multiple users, so it was just me. I don't think IT ever caught on.
