Hello everyone!Now more and more students are using mobile phones in my class. They text or use facebook to see all kinds of social software. They even used mobile phones to cheat on exams.Assume that I cannot confiscate them, and that I have already asked in polite ways. I have also tried logic (cell phones rot your brain) and religion (have damned them to Hell, etc.). Many thanks in advance!

Hi, Kellogg!
First of all, thank you for coming up with such a meaningful question.
As far as I'm concerned. Students should not be allowed to use mobile phones in school.
Why? Because using a cell phone can seriously distract students.
Maybe during the course of the teacher's lecture, the students were chatting on Facebook, or watching video on youtube.
Of course, this smart device can also be used for cheating or other purposes. You never know what purpose the cell phone will be used for in the hands of students.
As far as the solution is concerned, there are two feasible alternatives available for reference.
A: Build a large Faraday cage in the school building area. This can effectively block cell phone signals. But it's very expensive.
B: Use a popular cell phone jammer. This is one of the most popular devices at present. However, permission is required before use.
