Should smartphones be banned at secondary schools? Some people say that smartphones should be banned at secondary schools. They argue that mobile devices make academic performance worse and encourage cyberbullying. On the other hand, the constant exposition to smartphone screens could harm students sight. But I don't agree with this. I work as a secondary teacher since a lot of years. I can tell about my experience in Argentine's public schools. The former Argentine president, Cristina Kirchner, had given netbooks to all students from public schools. For this reason, most schools decided to dismantle their computer classrooms. But the actual president, Mauricio Macri, has discontinued this project. So public schools hasn' got any computers. Hence, the only way students have to access the internet is by their smartphones. And in my opinion, the use of the internet is crucial to learn everything nowadays. Besides smartphones contain many useful applications such as the calculator and word processor.
