Whether middle school students own or use mobile phones, using mobile phones to send text messages can be said to have become the main purpose of mobile phones, even if they use mobile phones to make calls. Students also mainly chat and ask about homework, and have little contact with their families.

As mobile phones enter the classroom, it will inevitably bring some disadvantages. Many students are addicted to text messages, sending all kinds of text messages back and forth, and even whispering to each other to exchange interesting news they have received.

Some students even bring their mobile phones into the examination room and use mobile phone text messages to cheat. Several such cheating incidents can be found in every midterm and final exam.

Not to mention the people who slip through the cracks in securities trading, there must be more.

In order to regulate the use of mobile phones by students, a certain school recently promulgated the "Interim Regulations on the Management of the Use of Mobile Communication Broadbands by Campus Students". The "Regulations" stipulate that mobile phones should not be used in all teaching buildings, laboratory buildings, audio-visual buildings, etc. during teaching periods; during examinations During this period, mobile phones should not be brought into the examination room.

The head teacher has the right to decide whether to allow students to bring mobile phones to school based on the specific circumstances of the school and students.

They can send text messages or play games in class secretly under the teacher’s eyes, which will definitely affect their learning. Thirdly, they are worried that mobile phones will become a new type of comparison object. , because mobile phone models are constantly being renovated, appearance, function, and price can all become the objects of comparison.

Many schools are well aware of the harm of mobile phones to students. All students know that mobile phones are not allowed in school. However, there are still many students who secretly take their mobile phones and claim that teachers dare not confiscate their mobile phones. The reason is: 1. They can easily defraud the confiscated mobile phones from their teachers under the guise that their homes are far away or their parents are out of town for a long time.

2. In the name of "gang", they intimidate informed students not to report them. 3. The teacher is not strict in punishing students and only gives verbal instruction when they see them playing with mobile phones.
