In today's society, computers are developing by leaps and bounds. Almost every family in the city has computers, and our lives cannot be separated from computers. As a "new generation", computers are an indispensable part of our study and life.
According to the survey of students around us, members of our project team think that middle school students use computers mainly for the following purposes: learning (including painting and writing), playing games (including enjoying music and watching movies) and surfing the Internet. The main uses of surfing the Internet are as follows: studying online, searching information, playing games (including listening to music and watching movies), chatting and making friends, etc.
According to statistics, the time spent playing games accounts for the largest proportion, almost reaching more than 6%.
Second, the positive role of computers in the growth and progress of middle school students:
At present, it is very common for middle school students to use computers, but there are advantages and disadvantages. Computers are easily accepted by middle school students, and their advantages are mainly as follows:
1. It is an important way to quickly master various knowledge
Computers have become an important source of knowledge. Most of the materials of the world's major libraries can be obtained online through computers, which is not only quick to consult, but also saves a lot of extra expenses. There are also news, materials, entertainment, literature and other information. Through the computer, we can see the latest, fastest and most authoritative news on the Internet, learn knowledge that books don't have, learn more extensive unknown information, and make more middle school students get closer to the forefront of science and technology faster, earlier, and make us love and admire science more.
2. Effective ways to receive education
At present, there are a wide variety of learning software, which is much more interesting and flexible than books, just like watching cartoons, and it is easy to attract our attention. A few thick books of the encyclopedia Britian and a small CD can be done. There is also the new teaching method of "online school", in which teachers teach you individually and "classmates" learn from each other in communication, which is completely free from the constraint of face-to-face with teachers in the classroom and is not bound by time and place, which is of great help to our middle school students' free play.
3. Computers are a useful tool to strengthen communication.
At present, middle school students are almost all only children. Except at school, we usually spend more time alone. While surfing the Internet through computers, we can chat in chat rooms or other communication websites such as OICQ. In this virtual world, we can talk about our favorite topics, and netizens, regardless of age and occupation, can express their feelings as long as they think they share the same interests. This is an excellent opportunity for us who are eager for friends, friendship and talk. We talked happily in the network and got spiritual relaxation and relief.
4. Computer is the helper of shopping
Now, computer shopping has become a fashion. We middle school students no longer need to squeeze buses. On the Internet, we can click the mouse and send the things you want to buy directly home, which not only saves time, but also is cheap, killing two birds with one stone.
Third, the negative effects of computers on the growth of middle school students.
Everything has two sides, and there are disadvantages in middle school students' using computers.
1. Children need to establish personal friendship with caring parents, but computers separate parents from children, which makes children "only recognize computers but not people" from an early age. Children who often play computer are generally taciturn, and their concentration time is relatively short, which reduces their learning motivation. Poor living ability, weak language expression ability, isolated, withdrawn, lack of enthusiasm for parents, lack of interest in life.
2. The computer makes us developing children spend more and more time sitting in front of the computer desk. Sitting in front of the computer for hours, staring at the screen, stiff neck and holding the mouse, these bad postures will cause many problems for a long time. However, the damage of bad sitting posture to muscles and other parts will not appear until 1 years later, so we still don't realize it, and it doesn't matter, until we know the consequences. Especially the harm to the eyes, Japanese researchers pointed out that after the popularization of computers, the number of nearsighted students has increased a lot. Glasses that were previously worn by college students are now quite common among high school students and junior high school students. At present, the myopia rate of middle school students in China has reached 6%, and it is increasing year by year. The image, standing posture and walking posture of children in the "computer age" are different from those of our parents, wearing glasses, tilting their heads forward and shrinking their shoulders. Some educators and children experts strongly urge schools to stop using computers at the basic stage, pointing out that using computers will do harm to children's physical, emotional and other aspects of development.
3. We middle school students are particularly prone to "infatuation" with computer games. Once addicted, we spend all our spare time playing computer games, neglecting our studies and declining our academic performance. Nowadays, computer games are mostly fighting and killing games, which are prone to violent tendencies in such an environment for a long time. However, we middle school students don't have a deep understanding of society, are very curious, and lack certain discrimination ability. It is easy to be deceived when making friends online, and some unhealthy content on the Internet is also very harmful to us.
Chatting and playing games have caused our academic performance to decline, which is harmful to our physical and mental health, which is not conducive to the healthy growth of our middle school students.
Computer is the progress of science and technology, which facilitates people to do things, helps people to learn, enriches people's lives, etc ... With the progress of science, people also invented the network, which allows people to learn knowledge, find confidants, and play games online, etc ... The network is really fun.
At present, the general craze for home computers has spread all over the cities and villages of China, and computer developers have turned their attention to families in an all-round way: the price of computers has dropped sharply, various home-use software has come out one after another, and computer training for parents and families is in full swing. Some experts even predicted that at the beginning of the next century, computers will be as popular as home televisions.
What computers do after entering the family is an important issue of concern to all sectors of society. From the current situation, more and more parents regard computers as one of the important means to educate their children. Relevant surveys show that nearly one-third of the families who have bought computers are used for their children's education; Nearly one-third of consumers who want to buy computers also said that buying computers is based on children's learning considerations. At some home computer fairs, parents solemnly promised their children that they would buy a computer for their children as an encouragement as long as they did well in the final exam or got into a key middle school.
There are disadvantages for primary and secondary school students to learn computer, but parents should never give up eating because of choking. The key is that parents should scientifically guide their children to learn and use computers, so as to play the educational function of computers.
(1) Before buying a home computer, parents should know something about the functions, usage and maintenance of the computer and the basic knowledge of the computer, preferably after a period of special training, so that they can be confident in guiding their children to learn and use the computer; At the same time, parents should realize that the educational function of computers is not only applicable to children. Parents should learn computer knowledge with their children, learn from each other and improve together. It is necessary to guide children to learn computers correctly and not to make them fans of computer games and VCD.
(2) The younger a child is, the better. It is generally believed that it is more suitable for children's physical and mental development characteristics to learn computers in the senior stage of primary school. Parents should stimulate their children's interest in learning computers, not force them to learn computers.
(3) When children are learning computers, parents should appropriately control their computer time, encourage their children to actively participate in various outdoor activities, expand their interests, and promote their physical and mental health. Parents should educate their children to correctly distinguish airborne information and enhance their immunity to adverse effects.
