Advantages and disadvantages of internet

The Positive Influence of Internet on Teenagers

1. is beneficial to the formation of teenagers' nonlinear thinking mode.

The linear thinking mode emphasizes the order of things, and the understanding of things follows a single order from beginning to end. However, hypertext reading, which is widely used in the network, constructs and processes information in the form of network. It is a leaping and comprehensive nonlinear way of thinking. From the nonlinear point of view, we must consider the relationship between the problem and the surrounding things at the same time, and seek the solution to the problem through this network connection.

This way of thinking has changed the inherent narrow and rigid disadvantages of traditional linear thinking, which is conducive to cultivating young people's divergent thinking, expanding their thinking, helping them to correctly look at people and things around them and establish a scientific outlook on life and the world.

At the same time, the use of network can also cultivate teenagers' thinking consciousness of looking at problems from a systematic point of view and actively using modern tools to analyze and solve problems, which is necessary in the information age.

2. Teenagers' creativity has been developed.

With the rise of several major Internet in China, young network founders have become role models for teenagers. The myth of online entrepreneurship and the story of online equality inspire a large number of energetic young people. The importance of knowledge and creativity has been deeply rooted in the hearts of young people. The information on the network is extremely rich and the update speed is very fast.

Faced with this huge amount of information, teenagers no longer value "rote learning", and computers and networks are their memories. The most important task they face is not to acquire known knowledge, but to create and apply new knowledge with high imagination. The network has revolutionized the concept of teenagers, greatly improved their innovative ideas, innovative thinking, innovative ability and innovative content, and sublimated their intelligence.

3. Meet the needs of teenagers for communication, communication and understanding.

Internet is an efficient, fast, convenient and unique way of communication, which meets the requirements of contemporary teenagers who are curious, like fantasy and pursue independence. Therefore, as soon as the internet appears, it is destined to be closely connected with teenagers. The network makes teenagers closely connected with the world, and enables them to gain a broader space besides the limited pressure of study and work. When colorful information resources from all over the world gather in front of teenagers, their vision and mind will be completely different from the past.

The healthy growth of teenagers under the network environment is an important theoretical and practical issue related to the training of successors to the socialist cause and the long-term development of the country. In this regard, we have carried out exploratory investigation, analysis and research, with a view to guiding young people to seek advantages and avoid disadvantages in the network society, and to coordinate the development of morality, intelligence, physique, beauty and labor, so as to serve the decision-making of the party Committee and government and the construction of two civilizations.

The influence of network on the healthy growth of teenagers is multi-level and multi-faceted, and generally it is dual. The definition of health by the World Health Organization is that health refers to a perfect state of physical, psychological and social adaptation.

In China's educational policy, it is also clearly stated that teenagers should be cultivated into "four haves" with all-round and coordinated development of morality, intelligence, physique, beauty and labor, "facing modernization, the world and the future". Therefore, we try to explore the dual influence of the network on the healthy growth of teenagers from the aspects of their ideological and moral quality, intellectual quality, physical quality, psychological quality and social adaptability.

Negative network influence

1. The negative impact of the Internet on teenagers' ideological and moral quality is mainly reflected in the following aspects: the flood of network information may cause the lack of teenagers' beliefs or the diversification of values, and affect the formation of teenagers' correct outlook on life and values; The concealment of network information reception and dissemination may lead to the weakening of teenagers' moral consciousness and the decline of social responsibility. Internet communication is hidden and unconstrained, and it is easy for teenagers to do some unconventional things and even embark on the road of crime.

2. The negative influence of Internet on teenagers' intelligence quality is mainly reflected in the following aspects: online chatting is the main content of many teenagers surfing the Internet, and most teenagers who enter chat rooms have no fixed topics. This kind of rambling chat easily affects teenagers' logical thinking ability and attention; Computer network occupies the time for teenagers to read and think;

3. On the Internet, some people make money by helping others write papers and do their homework, so many teenagers who lack self-discipline download articles from the Internet and give them to their teachers to do their homework. Even master's and doctoral theses are bought from the Internet, which greatly reduces the seriousness of teenagers' learning. In reality, many teenagers are addicted to the internet because of their excessive infatuation and dependence on the computer network, and their normal order of study and life is destroyed, their study time is listless, their academic performance drops, and some even get tired of learning, play truant and drop out of school.

4. The negative effects of the Internet on teenagers' physique are mainly reflected in the following aspects: surfing the Internet for a long time will cause depression, dizziness, shaking hands, fatigue, loss of appetite, anxiety, hypertension, autonomic nervous dysfunction, sleep disorders, and some even commit suicide passively; Bad network environment will also damage the health of teenagers.

5. The negative influence of Internet on teenagers' psychological quality is mainly reflected in the following aspects: long-term surfing the Internet will lead to teenagers' onlineness, apathy of interpersonal feelings, and the psychology of not agreeing with or even escaping from the real society; "Online dating" and online chatting will lead to a series of emotional entanglements among teenagers, leading to various emotional problems; The virtuality and concealment of the network will induce the double personality disorder of teenagers; Out-of-control network manipulation time can also lead to internet addiction, which makes teenagers become lonely, sensitive, depressed, alert, disobedient to social norms, and even appear mental disorders and suicidal behavior.

6. The negative influence of Internet on teenagers' social adaptability is mainly reflected in the following aspects: Internet is a virtual world, and people's online communication mainly depends on abstract numbers and symbols. Teenagers are addicted to this man-machine conversation mode all day, which will affect their social adaptability and ability. What's more, some teenagers may suffer from "network social obstacles";

7. Under the network environment, the uncertainty of the object and identity of teenagers' communication weakens their ability to obtain social roles; The virtuality and freedom of network communication easily lead to the general anomie of people's behavior, which is not conducive to the socialization of teenagers, and even leads to the failure of teenagers' socialization.

Extended data:

Experts in China and the United States have published research reports, warning that excessive surfing on the Internet may lead to brain variation of teenagers, shrink the gray matter of the cerebral cortex responsible for dealing with emotions, language, vision and hearing, affect attention, memory, decision-making ability and even long-term goal-setting ability, weaken teenagers' restraint ability, and easily lead to "inappropriate" behavior.

Experts estimate that there are about 24 million teenagers addicted to the Internet in China, and the relevant research is also aimed at college students in China.

Researchers from Peking University, Chengdu University, Sichuan University, China Institute of Science and the University of Florida first discovered 18 college students who were addicted to the Internet. On average, they surf the Internet for 6.3 days a week (average 10.2 hours) and 8 to 13 hours a day. In addition, 18 college students of the same age who spend less than 2 hours online every day and are not addicted to the internet are the control group.

The researchers compared the brain magnetic resonance scanning (MRI) of the two groups of students, and found that the gray matter of the internet addicts shrank. The longer the addiction time, the more serious the gray matter atrophy. In addition, the white matter responsible for transmitting information inside the brain has also changed. According to the researchers, these brain structural variations are caused by internet addiction, which will make teenagers' cognitive function defective, more likely to rely on the internet, and even have long-term dysfunction.

Surfing the Internet for a long time is definitely bad for your health. A man in Tongzhou District of Beijing died suddenly after 36 hours of continuous surfing the Internet, which should be a wake-up call for people who have been surfing the Internet for a long time. For the sake of health, try to reduce the online time.
