Will cell phones really destroy children? This is a controversial topic, and different people may have different views and positions. I will try my best to put forward valid arguments for the pros and cons fairly, refute the opposite views and draw convincing conclusions based on the evidence. The following is the content of my debate: Pro: Mobile phones will really ruin children's eyesight health. According to the research, if children play smart phones for 20 minutes continuously, their eyesight will drop to 43.8 degrees myopia on average, and the average tear film rupture time is 5.3 seconds, with an average of 7.67 blinks per minute. However, after playing the tablet computer for 20 minutes, the children's eyesight dropped to 465,438+0.7 degree myopia on average, and the tear film burst time was 5 seconds on average, with an average of 4.67 blinks per minute. Watching mobile phones for a long time can lead to dry eyes, dry eyes and sore eyes. Myopia will gradually occur. At present, there are 600 million myopia patients in China, and the myopia rate of teenagers ranks first in the world. The myopia rate of high school students and college students has exceeded 70% and increased year by year, and the myopia rate of primary school students is close to 40%. Mobile phones will affect children's brain development. If teenagers are exposed to the radio frequency electromagnetic field generated by mobile phones for a long time, it will adversely affect the development of memory performance in specific areas of the brain. Research in the British magazine Microwave Theory and Technology shows that the skull thickness of children is obviously lower than that of adults, and the absorption rate of radiation is obviously higher than that of adults. The child's nervous system is in the development stage, and the potential threat is even greater. Researchers at Cincinnati Children's Hospital Medical Center found that the time spent by preschool children using electronic products is inversely proportional to the level of white matter development. White matter nerve fibers are the key structures that affect children's language learning, literacy and cognitive level. Mobile phones will affect children's learning and growth. Playing mobile phones for a long time will distract children and affect classroom listening, homework completion and exam results. Researchers at Rutgers University in the United States conducted an experiment and found that if students were allowed to use electronic devices such as mobile phones for non-academic purposes, they would perform poorly in the final exam. Louis Philippe Behlander of London School of Economics and Political Science and others have found that banning the use of mobile phones in schools can improve children's academic performance by 6.4% on average, and the progress rate of poor students is as high as 14%. Playing mobile phones for a long time will also delay the development of children's language, sports and social skills. A study on the early development of 24,465,438+0 mothers and children in the University of Calgary, Canada, evaluated the relationship between the time these children spent staring at the electronic screen and the development of behavioral ability through developmental screening. The results show that the more time children spend using electronic screens than recommended by the American Academy of Pediatrics (AAP) guidelines (1h), the worse their performance in developmental screening tests. Mobile phones will affect children's mental health. Playing mobile phones for a long time will make children addicted to games and lack real interpersonal communication, leading to psychological problems such as self-isolation, inferiority and loneliness. A study conducted by San Diego State University in 20 16 followed 40,337 children aged 2- 17 in the United States. The results show that after using mobile phones and other electronic products 1 hour every day, the longer the children watch the screen every day, the lower their mental health level, their curiosity, self-control ability and concentration are not concentrated, the more friends they are difficult to make, their emotions are unstable, they are difficult to take care of, they cannot complete tasks, and they are more likely to suffer from anxiety or depression. Mobile phones can expose children to bad information. There are all kinds of contents on mobile phones, both beneficial and harmful. Children do not have enough judgment and resistance, and are easily influenced and tempted by bad information. For example, information such as violence, pornography, gambling and fraud may make children imitate, indulge or be deceived. There are also some bad games and challenges on mobile phones, such as Blue Whale Games and Momo Challenge, which may induce children to self-harm or commit suicide. These are all factors that cause great harm to children's physical and mental health. Counterparty: Mobile phones won't ruin children. Mobile phones are not the main cause of myopia. Myopia is a complex disease caused by many factors, among which genetic factors account for a large proportion. Moreover, there is no authoritative scientific evidence to prove that watching electronic products such as mobile phones will directly harm children's eyesight. Authoritative institutions such as the American Ophthalmology Association (AAO) and the American Optometry Association (AOA) also pointed out that the use of electronic products is not the cause of vision loss. Researchers at Ohio State University conducted a 20-year follow-up survey on 4,500 American students aged 6-1/kloc-0, trying to find out the relationship between their habit of watching TV (and other electronic products) and their eyesight. The conclusion is subversive. Being too close to the screen of electronic products or watching the screen for too long is not the culprit of myopia. Cell phones don't necessarily affect brain development. At present, the research on the influence of mobile phone radiation on brain development is inconclusive, and many studies have methodological defects or inconsistent results. For example, some studies fail to consider other factors that may affect brain development, such as heredity, environment and nutrition. Some studies have no control group or the sample size is too small to be extended to the whole population; Some studies have found that cell phone radiation has a negative impact on brain development, while others have found that it has no or positive impact. So we can't simply think that mobile phones will destroy children's brains.
Mobile phones can promote children's learning and growth. Mobile phone is a powerful learning tool, which can provide rich information and resources, help children expand their knowledge, improve their learning efficiency and stimulate their interest in learning. For example, children can look up materials, watch teaching videos, participate in online courses and do online exercises through mobile phones to increase the depth and breadth of learning. Mobile phone is also an effective communication tool, which can help children establish and maintain social relations, cultivate communication and cooperation skills, and enhance self-confidence and self-esteem. For example, children can keep in touch with teachers, classmates, family and friends, share their thoughts and feelings, seek help and support, participate in social activities and public welfare projects, and expand their social circle and sense of social responsibility.
Mobile phones can improve children's mental health. Mobile phones can provide entertainment and relaxation for children, relieve stress and anxiety, and increase happiness and satisfaction. For example, children can play some useful games, listen to some relaxing music and watch some interesting videos through their mobile phones to adjust their mood and mentality, release negative emotions and cultivate positive emotions. Mobile phones can also provide psychological assistance and consultation for children, help them solve psychological problems and improve their psychological quality. For example, children can consult professional psychological counselors through mobile phones, participate in online psychotherapy or intervention, download some applications that are helpful to mental health, and enhance their psychological resilience and adaptability.
Mobile phones can protect children from bad information. Mobile phone is not a source of bad information, but a medium. The existence of bad information is a reflection of social reality and cannot be completely avoided or eliminated. However, mobile phones can provide children with some methods and skills to prevent and deal with bad information, help children identify and resist bad information, and protect their own safety and rights. For example, children can set privacy protection through mobile phones, block harassing calls or text messages, report bad content or behavior, and reduce the impact of bad information on themselves. Mobile phones can also provide some positive and healthy information and content for children, help them establish correct values and world outlook, and improve their literacy and moral level. For example, children can read some useful books, watch some educational programs, pay attention to some positive people or things, and increase their knowledge and wisdom.
Conclusion: Mobile phones will not destroy children, but how to use them correctly is the key.
To sum up, the influence of mobile phones on children is two-sided, with advantages and disadvantages. Mobile phones will not destroy children, but how to use them correctly. As parents, children should not be forbidden or allowed to play with mobile phones blindly, but should reasonably plan the time and content of using mobile phones, guide children to develop good habits of using mobile phones, educate children to identify and resist bad information, supervise and protect the safety of their mobile phones, and set an example by playing less mobile phones and spending more time with children. Only in this way can mobile phones become a good helper for children's learning and growth, not a bad influence.
