For many years I have thought that elementary schools should be free of any modern electronic tech. In middle school it should be introduced but not connected to internet (word processors, interactive encyclopedias or coding like we used to learn it in the '80s or '90s, BASIC, Logo, that kind of stuff).

Finally, introduce internet in high school, in a controlled way, focusing primarily on knowledge and research sites. No LLMs included.

Of course you can't control what happens in the students' homes, but that should not affect what happens at school, specially if you replace homework with schoolwork, which I also think it's better in the long run.
