Well, how are teachers supposed to enforce a ban on smartphones, then?
Have you never played Tetris? Any Gameboy game where you have to level up (like Final Fantasy) will also be a severe temptation as you have something productive to do while the teacher yammers about stuff you either already know, has nothing to do with you (e.g. talking to another student), or don't care about (like really I do not care about the difference between "predicate nominative" and "subject complement").
Also the original Game Boy was a bit too big to bring into a class and not get caught, but Game Boy Advance SP was perfect.
None of this is new. Children being distracted in classrooms is nothing new. If there's children, there's socializing, playing games, and ignoring adults for the much more interesting other children.'
Cell phones are just the new boogyman, like CD players and walkmen and gameboys etc. were back in the day.
No, but we can take the electronic device and log it into the office so that a parent has to come retrieve it. And if I happen to forget a couple of days and only manage to log it in on Friday so that they don’t get it over the weekend, well, I’m a forgetful chap.
That threat alone, not having a phone over the weekend eliminates 90% of phone issues in my classroom.
Also, if your argument is "gameboy existed". People just did not use it as much. Today smartphone usage in class is rampant. Also gameboy games were not anywhere near as addicting as games and social media are today.
