It is very inconvenient to not be able to use mobile phones in the student dormitory

At around 11 o'clock yesterday morning, reporters came to the entrance of the middle school for interviews. A senior high school girl confirmed the netizen’s complaint. She said: "The dormitory building has been equipped with jammers. As soon as I return to the dormitory after class, there is no signal on the mobile phone." The cousin who came to pick her up said: "Her mobile phone often has no signal and she cannot contact anyone in time. If it’s really urgent, you have to tell the security guard and then communicate it through the security guard.”

Xiao Su, a second-year junior high school student, also said that the high school dormitory building is indeed equipped with jammers, but the junior high school has not. However, she heard that the junior high school will also install jammers next.

Several first-year high school boys further revealed that the school installed mobile phone signal jammers in the second semester of last year, and the jammers were installed in their dormitories. “When I have dinner at noon or return to the dormitory after class in the afternoon, there is basically no signal. You have to use the dormitory phone for phone calls." When the reporter asked them if they had mobile phones, a boy shouted: "If there is no signal, it is useless to have a mobile phone!"

The reporter followed several boys to the high school boys' dormitory. In the dormitory on the second floor, a boy led the reporter to find the jammer in the corridor. The reporter then tried dialing a few calls on his mobile phone in the corridor, and the call went through. "The jammer is sometimes on, sometimes off. Maybe it's not on now," the boys said.

One boy said: "The jammer makes people feel like they have a headache. Three or four students have this feeling."

The school has carefully considered and solicited opinions in advance

The relevant person in charge of the middle school told reporters that the school installed mobile phone signal jammers after careful consideration. There were four main considerations.

The first consideration is that some students will send messages to each other through mobile phones during exams, and even search for essays online to plagiarize. It is hoped that installing a blocker will prevent candidates from using mobile phones to cheat.

The second is that many students will lie in bed and surf the Internet after class or evening self-study. However, there is a lot of bad information on the Internet, which is very detrimental to students' growth and learning.

The third reason is that some students send text messages and make love calls after studying in the evening and before going to bed, which affects their study the next day. They are already high school students and are in a critical period.

Fourth, during the period after lights out for evening self-study, students are doing various activities on their mobile phones while lying in bed, and student administrators have no control over the students.

The person in charge said that in view of the above factors, the school chose to turn on the jammer to block mobile phone signals during the two periods of time after the lights are turned off at noon and evening self-study, "outside the monitoring line of sight", and the jammer was turned off at other times. He said that the school also considered that it could not affect the contact between students and parents, so it reduced the coverage of the jammer to only the dormitory buildings. "It will not affect the communication between home and school. The dormitories have fixed phones and IC card phones, etc. It will not affect the communication between students and teachers."

Before installing the jammer, the school did some research. The person in charge said, "The school sent a letter to parents, and many parents supported this approach." In addition, the school also held a mobilization meeting for students. Most students were in favor, but only a small number of students had opinions.
