I am a middle school teacher. Recently, I found that more and more students use mobile phones in class. In addition to texting, they use their mobile phones to log on to facebook or youtube. I don't think these social apps will help them learn, so I want know how to stop cell phone signals in the classroom now
Although it is wrong to use mobile phones in class, but I think it is very difficult to forbid students to bring mobile phones to school. After all, no one can live without a cell phone.
If you want to ban cell phone signals in the classroom, there are several ways to do this.
If your school has recent alterations or renovations, you can propose a Faraday cage. The signal will be greatly weakened. But it's not cheap
If you want to be quick and cheap, consider placing a cell phone jammer in the classroom.
