5 of these teachers had zero issues keeping him off of the device (now an iPad). The sixth was (from what we could tell) just not particularly gifted at classroom management in general. Anyway missing out on some unknown fraction of 1/6th of his education was much less of an issue than missing out on 90% of the classroom time (thankfully there were no chromebooks in PE or Music class yet; surely they'll find a way to do that too at some point).
And the worst part is that this isn't new. Back when I went to elementary school (early 90's) this already happened in the computer lab. A few years later my mom volunteered in the computer classes; one had internet, so naturally as soon as she turned her back there was a gaggle of kids around it to look at nudes.
But they haven't learned. And they got a bag of money post-covid to help kids catch up on missed classes, which they spent on computers and IT, and some opt-in external homework help.
Kids's attention spans (and their parents, for that matter) are all over the place, giving them any screen will just trigger their dopamine hit seeking automatisms.
I mean yes, everyone needs to learn how to use a computer - a lot of these kids didn't know what a file is - but make it focused, make it supervised, and lock these systems down.
