the aim of this writing is to observe the harmful effects of cell phones by closely evaluating the many negative. Many people say they are education tools and should be at school. In my opinion Cell phones should not be allowed in classrooms because they cause students to want to cheat, are a distraction and students can cyberbully via them during class hours. In fact schools should not allow students to have their cell phones with them in class because students can cheat via cell phones on tests. As a result only in case of family emergency, the teachers have a cell phones and the parents could call them. In some countries having a mobile is totally illegal. It should be mentioned that they are some reasons that makes you to bring your phone to school. Imagine you are a student and a school shooting happens, you need to get in contact with emergency services and cannot reach the classroom phone, but you have your cell phone in your pocket. Another scenario for students why students should be allowed to have their cellphones in school is their might be a family emergency such a parent being in an accident or a grandparents died. Having a phone would allow the students to be updated and be able to leave arrange to leave school early.
