The nation’s second-largest teachers union said Thursday it was losing patience with social media apps that it says are contributing to mental health problems and misbehavior in classrooms nationwide, draining time and money from teachers and school systems.
Signal jammers are illegal. Certainly wouldn’t be a good idea to install those in the US, where school shootings are common.
Edit: Also, unrelated to the signal jamming thing you talked about:
Phones are useful in case of a fight were to occur, which happen very often (at least in schools I went to). Video recordings are good to determine fault. School surveillance cameras are often cheap, blurry, unreliable, have many blind-spots, and also forbidden in classrooms (at least in the US). In addition, sometimes classrooms still use old textbooks that only have 1 class set, and are very heavy to carry, and they aren’t available online, so in that case, kids can just take photos of the textbook and the school saves a lot of money from having to copy-print the textbooks, so maybe they just need to make 1 or 2 copies for the kids that don’t have a phone. Phones are very useful, just needs reasonable rules. A complete ban is not necessary in my opinion.
