Generally, radio signal shielding is only approved when important situations such as the college entrance examination occur. Moreover, from the perspective of the "control area", signal shielding in our school does not exist. According to many students, signal shielding not only covers the nearby corridors, but also seriously affects the quality of self-study. In addition, according to our tests, outside the school, near the corridor of Qinsu Building, the signals of operators are interrupted one after another. Taking China Mobile as an example, the signal is about 20dBm lower than when it is not installed, and the SINR signal-to-noise ratio has also dropped from the normal 11-15 to 3-8. The value of the signal has greatly changed the function of the Internet. We noticed that even passers-by passing by the school will send out false signals on their mobile phones. Portable WiFi jammers in the classroom should not be missed. We collected data. In order to obtain more accurate analysis data, we will next conduct in-depth communication with the three major operators.
We noticed that several third-grade students have communicated with relevant teachers and principals, but the communication has not yet achieved any results.
Even in the eyes of some people, the quality of students' learning is indeed "guaranteed". However, we must not believe that installing mobile phone jammers is an ideal method. Because no matter what method is used to ensure the quality of learning, it cannot exceed the upper limit prescribed by law. Teachers can take other consistent and reasonable measures to ensure the quality of students' learning. Installing mobile phone jammers in the classroom not only seriously violates students' imagination, but also creates rebellious emotions in students' hearts, leading to alienation, breakup and even conflict between students and schools, causing greater harm to students.
In the process of collecting and analyzing data, we received a new message: in order to prevent students from turning off mobile phone jammers privately in class, the switching of some jammers may have been cancelled (to be honest, we hope this message is false). This completely eliminates the possibility of some kind of compromise-for example, turning on the mobile phone jammer during the test and turning it off at other times-pushing the above contradiction to an incompatible point. Many students said that they felt that the school no longer trusted them.
Block teaching area in teaching management
Some students who fainted in class may be texting on their mobile phones. If they don't want to go to class during class, they don't need to go to the nearest office to whisper and chat. Easily send and receive text messages on your mobile phone.
Nowadays, mobile phones can access the Internet, and students can often chat, read novels, and play games on their mobile phones during class.
The school installs and uses a smartphone jammer management system to prevent students from abusing their phones in class. However, when mobile phone signals are blocked in the classroom, some students say that the school violates the "students'" right to communicate freely. From the perspective of students who often use mobile phones, these views seem to make sense. But think about it carefully. If blocking mobile phone signals violates students' right to communicate, then these students are using their phones during class or self-study. Have you ever thought that you have violated other students' right to education? Have you ever thought about respecting the teacher's teaching license? Whether it is rights or freedoms, there are only relative, not absolute. All rights or freedoms are based on respecting the rights of others. The law is also a rule based on the interests of the majority. This rule protects the rights of the majority. If we really want to talk about counterfeiting, the fact is that a few students use mobile phones at will regardless of the occasion, which violates the educational rights of most students.
Some students or parents may also suggest that the school block mobile phone signals in class. What if there is an emergency at home that needs to be contacted or the student himself is not notified? In fact, this question is not difficult to answer. From the student's point of view, the reason why students use mobile phones is to facilitate their parents. In fact, as long as there is no emergency, students do not need to be in school 24 hours a day. In special cases, the school, teachers and parents will take the initiative to establish contact. Second, from the perspective of parents, I remember a few times when children were equipped with mobile phones because of special circumstances. If they had to make a phone call, they would immediately stop the class and let the school handle it?
