This doesn't go far enough, in my opinion. I think all screens should be banned from schools. No TV, no phones, no projectors, no slides. No shortcuts for anybody, no distractions. Everything handwritten. I know this sounds like I'm sarcastically criticizing phone bans but I'm serious.
(Edit: obviously will need some accommodations for disabled students, and computer labs will have to exist for technical literacy classes.)
Whether those things are distractions depends on what they're used for.
I'm fairly certain schools had projectors a few decades ago, and nothing bad came of it.
You don't really need to ban phones from schools; just ban them in class. I don't know why this stuff is treated as such a big deal. Students should pay attention in class, which means not using anything (not devices, paper, books, etc.) except as needed for instruction.
How would that be beneficial? We don't need to make teachers' jobs more difficult than they already are by removing all the aid brought by digitalization.
TVs are good when used appropriately. We watched Macbeth for the literature class.
Actually, I benefited from a school-issued Chromebook. I mostly used it for note-taking (I'm bad at handwriting) and homework. Even though it allowed some simple browser games, I suspect it was less distracting, and the browser games could've been banned if the school used a whitelist to make it even less so. Even with paper students can be distracted by doodling and daydreaming.
But I wouldn't oppose banning those as long as the schools provided an AlphaSmart (because again, I'm really bad at handwriting). I think e-readers would be best but those are expensive.
I think banning tools for teachers, like projectors, is unnecessary. I suspect I learned easier from projected computer screens vs. staring at a whiteboard, but anything projected on the screen (e.g. powerpoint presentations) could be passed to students on paper, except movies but those may rarely be necessary.
