Summarize the disadvantages of students using ordinary smart phones, including but not limited to the following situations:
1. Bad information defiles the soul. In addition to bad websites, it also includes bad content spread through short messages and mobile phone memory cards, such as pornographic novels, ugly women, ugly jokes and so on. It is understood that a middle school in Beijing once conducted a survey: 70% of the mobile phone messages sent and accepted by students are messages unrelated to normal study and life, and more than 10% are yellow messages. Some students even consider it fashionable to forward "embarrassing beauty" and "embarrassing jokes" to each other.
2. Most online games or mobile games have addictive effects. Scientific research has proved that the addiction mechanism of online games is very similar to drugs, which has serious harm to teenagers. Some members of the United States even suffered serious physical and mental injuries because their children were addicted to online games, so they strongly advocated legislating in Congress to ban online games. Children who used to indulge in online games can only go to internet cafes to play, and there are many restrictions on time and place. But with smart phone, he can play anytime and anywhere, which is more convenient and frequent, so the harm is increased.
3. SMS chat affects rest and delays learning. Most parents report that their children talk less about their studies on their mobile phones, and communicate with their classmates or send text messages on their mobile phones. Among the two classes surveyed, the grade of Class A is obviously higher than that of Class B, which shows that the influence of mobile phone on learning will definitely be greater.
4. Encourage students to keep up with the joneses. Every spare time or after school, some students will get together to "learn" the styles and functions of mobile phones. There are more and more mobile phones on campus, and the grades are getting higher and higher. For those students who don't have mobile phones, it is easy to cause psychological imbalance. Under the influence of the wind of comparison, some students began to chase blindly, because mobile phones are updated very quickly, and their shapes and functions are changing with each passing day, and students will show off their status at home and their parents. This will make students regard their parents as their backers and not make progress.
5. Add extra burden to parents. A sample survey conducted in schools shows that all the funds for students to buy mobile phones come directly or indirectly from their parents. In addition, there are telephone charges ranging from tens to hundreds of yuan per month that parents also need to pay. After a year, parents spend at least 500 yuan on their children's mobile phones. For families with poor economic conditions, buying a mobile phone for their children is equivalent to adding a new burden to parents.
6. Mobile phones provide conditions for cheating in exams. There was an incident in which students in a high school in 2007 were punished for cheating with their mobile phones. Cheating with mobile phones is an open secret. A message can be sent to several students, and the scope of cheating is very wide.
7. Affect campus safety. Some brands of mobile phones have become valuables because of their high prices, and the second-hand market can be directly realized. If there is bad behavior, students will steal it. It is reported that some classes in a school have money and wallets stolen, and mobile phones will be stolen if they are not carried with them. In some developed countries, school administrators encountered this problem earlier than we did, and the adverse effects brought by mobile phones were more prominent, even leading to middle school students committing crimes. Middle school students with mobile phones have also become targets of fraud and robbery by some lawless elements.
8. Using mobile phones will hinder the order of education and teaching in schools. In class, some students make phone calls suddenly without turning off their cell phones, which will affect the attendance of all students and bring unpleasant emotions to the whole classroom.
But from another perspective, if it can be properly used and restricted, there are still many benefits for students to use smart phones. For example:
1. As a daily communication product, smart phones can really bring a lot of convenience to our study and life. Students can contact their parents in time through mobile phones, report their studies to teachers, communicate more with former classmates, maintain friendship with classmates, and communicate more with classmates can enhance friendship. When they encounter problems, they can discuss them with their smartphones.
2. A smart phone is actually a complete computer. Due to the rapid improvement of performance, the performance of smart phones has far surpassed that of early computers in many aspects. At the same time, because the smart phone itself has a variety of sensors, such as microphones and speakers, position sensors (GPS, Beidou positioning, etc. ), acceleration sensor, atmospheric pressure sensor, front and rear cameras, light intensity sensor, temperature sensor, etc. Its functions and applications have greatly surpassed those of ordinary computers.
3. The clock, calendar and alarm clock functions of smart phones can be used at any time and become an important assistant for students' daily study and life.
4. Large-screen smart phones can carry a large number of learning-related software and applications, such as the most comprehensive scientific calculator, Xinhua dictionary, Chinese idiom dictionary, English-Chinese dictionary, Oxford dictionary, synchronous tutoring materials, various question banks, various extracurricular tutoring materials, and a large number of classic books. It has become an important learning aid for students.
5. You can record some meaningful and valuable course contents and blackboard pictures at any time by using the memo, recording and shooting functions of smart phones.
6. The smart phone itself is small and light, and can be carried around. Compared with all kinds of bulky books, smart phones can actually reduce the weight of students' schoolbags, which is conducive to the healthy growth of students' skeletal system.
7. When students go out to play or encounter danger in other places, they can use the communication and positioning functions of smart phones to ask parents, teachers or police for help in time.
