The mobile phone is undoubtedly a very convenient tool. However, depending on the time and place of use, normal public order may also be hindered. Such as libraries, classrooms, etc.
There is no doubt that smartphones have extraordinary functions that can theoretically promote student learning. But the fact is that despite the best efforts of parents and teachers, children still mainly use mobile phones to access digital entertainment.
Needless to say, mobile phones should not be used in classrooms. Mobile phones are not allowed in the classroom, but teachers don’t want to enforce the rules. They often complain that I should find a solution so that they don’t have to argue with students. A friend of mine used to be a teacher. His students used to send text messages in class and later bought a portable cell phone jammer. Then all the students felt that their phones could not receive any signals.
The principal of high school purchases cell phone signal jammer from dealers to prevent students from using cell phones in school in violation of school district policy. First, he may be tired of abusing mobile phones on campus, and his decision may be due to cases where the learning environment he tried to create was seriously damaged. However, it is frustrating that education efforts, deterrence strategies, formal policies, and vigilant supervision and sanctions have not sufficiently reduced the problem.
The school will restrict the use of students’ mobile phones during class, so as to clearly promote students’ academic success and safety. At present, most schools will let teachers install signal jammers in their classrooms. But this piecemeal approach leaves teachers with insufficient support to cope with difficult and potentially unsafe tasks that provoke students to restrict destructive phone use.
Some people think that mobile phones should not be used during learning because children will not be fully focused on their work. Children can go online to play games, but it does not help their learning. Children will be distracted by the ringtones on their phones or the flashes of other children taking pictures with their phones. Mobile phones should not be allowed to go to school during the study period.
In addition to sending text messages, jammers can also effectively prevent students from cheating on their mobile phones. Cheating is always repeated. Facing this situation, educators must use jammers to prevent cheating.
Now not only educational institutions in China are using mobile phone signal jammers, more and more countries are introducing signal jammers into educational institutions.
