Recently, a principal in Spokane, Washington, bought a cell phone jammer to prevent students from using a cell phone during class. the signal jamming devices are turned on during class hours and off during shift and lunch hours. The reason he bought the jammer was that students were frustrated by the constant texting and cell phone calls during the course.
I think it's a good idea. I did n’t have a cell phone in school. Although I know many people would say that I did n’t have a cell phone when I was in school decades ago, in fact we live without them. If we are sick and have to go home, we go to the office and use the phone. There is a public telephone in the lobby. When I was in school, I was interested in learning and playing in school. Therefore, I think it is necessary to install a signal jammer in school to avoid students being too addicted to mobile games.
The principal did not bother the phone all day, just during class. Not only that, the school also has regulations prohibiting the use of mobile phones in schools, especially during school hours. Especially during school exams, cheating may reach a whole new level, as children can send replies to each other via text messages. Not only that, mobile games and gossip may become the top priority of learning. Are jokes and gossips bad enough in high school without texting during class? So a month ago, he found an online store in China and bought special signal blocker equipment to block the phone signal.
