I commissari sanitari chiedono il divieto dei cellulari nelle scuole di Berlino

TL;DR:

The three local representatives said that mobile phones must be banned in schools because the “psychological, physical and social disadvantages of unlimited smartphones during school hours far outweigh the advantages”.

According to figures from the European Parliament, 210 million people in the world suffer from smartphone addiction. In Europe, 71 percent of young people sleep next to their smartphones and 10 percent check their phone more than 10 times per night. Teens who spend more than five hours per day on their phones are also twice as likely to develop depression.

Rules in the neighbouring federal state dictate that Grundschule (elementary school) “pupils’ private, digital devices should be stored in their bags or lockers during lessons”.

In July 2023, Dutch Minister for Education, Culture and Science, Robbert Dijkgraaf, announced that from January 2024 mobile phones and smart devices would no longer be allowed in classrooms in the Netherlands to prevent pupils from becoming distracted.

Almost a year after the ban had been imposed, hundreds of Dutch students told a poll that they were socialising more and their social interactions were of a higher quality. There had also been a decrease in cyberbullying.

Here (a school in lower Saxony) mobile phones Are already banned and rightly so. They are just really really bad for kids.
