Text / Ou When the children who are jumping and jumping are sitting in front of the TV, they become quiet and honest, and see everything around them as nothing. This phenomenon was once called "zombie effect" by American education expert Jenny Healy. Today, new members are added to appliances that turn children into "zombies": smartphones and tablets. This type of device featuring a touch screen has not been around for a long time, but it has become a playmate for many children, creating a "touch screen generation." For experts, the impact of touch screen devices on children is becoming a new research topic. Interaction helps to develop cognition Today, tablets are an indispensable "companion" for many children in their daily lives. Compared with smartphones, tablet touch screens are larger, making it easier for younger children to touch the operating position with a little clumsy hand. When children learn to operate a computer mouse or TV remote control, it takes some time to establish the connection between their action and the screen, but with the touch screen device, even toddlers can learn to operate immediately, let the screen The car ran, the bug crawled, and "takes up" the brush to draw... In many families, the child is an "expert" who plays these devices. Experiments by Joel Jean Trosese, an expert in developmental psychology at Vanderbilt University in the United States, have shown that for toddlers, children around the age of two, screen interaction helps to develop cognitive abilities. Lisa Gernzi, director of the Early American Education Program at the New America Foundation, believes that a good touchscreen device application can promote brain activity in children. However, she reminded that the interaction between the child and the parents is the key to the advantages of the touch screen technology. The touch screen device can not replace the parents' words and deeds, especially for the children. In his book Screen Time: How Electronic Media Affects Young Children, Gernzi writes that children under two years of age need to interact with real people as a basis for learning. Most parents are cautious The Joan Ganz Cunny Center has invited some 5-year-old children to use a word-teaching apple education application and found that their children's vocabulary increased by an average of 27%. Another similar application for 3-year-olds is equally good, helping children improve their vocabulary by 17%. The Cunny Center recently conducted a study comparing the effects of children reading paper and electronic books. The study concluded that paper readings are more effective in cultivating low-age children's learning focus. For older children, electronic reading materials are more likely to stimulate their reading interest. Although some studies have shown that touch screen devices have certain advantages in improving children's cognitive ability, whether or not the benefits outweigh the disadvantages is inconclusive. According to the Hannah Rosin editor of the American Atlantic Monthly, American parents mostly adopt a conservative attitude toward the use of touch screen devices. Senior children's media researcher Barclaysna invited dozens of children's app developers to meet last spring to let them meet with some parents and children to collect user feedback. Many of these developers took their young children to the meeting. Luo Xinben thought that the developers supported the children to use the touch screen device, but the results surprised her. A female teacher has developed an app to help teach children spell words. Rosin asked the developer what application her child was playing in order to introduce herself to the three children who love to play the touch screen device. The developer replied that she only allowed the child to play the “certainly educational†application, and only allowed the child to play on the weekend, and to take a break for half an hour. Rosin asked several developers and got a similar answer. One person said that only children should be allowed to take a long-distance trip by plane or by car, and the other said that they only let the children play for half an hour every day. "Wall Street Journal" reporter Ben Watson said that he confiscated his child's iPad, because the child is too engaged in playing, the name is not agreed. Rosin said: "Although technology has become ubiquitous in our lives, American parents are not more concerned about the impact that technology may have on children, but instead become more cautious." Promote learning with interest Compared with the cautious attitude of many parents and scholars on touch screen devices, education expert Mark Plansky is quite aggressive. Plansky created the term "digital natives" to refer to people born during or after the massive introduction of digital technology. These people have been exposed to digital technology since childhood, and their understanding of digital technology is much deeper than others. The "digital foreign households" corresponding to "digital natives" refer to those who were born earlier and later approached digital technology. Plansky believes that today's children are different from the past and advocate the use of children's passion for technology to promote their learning. Plansky said: "The war will end, the digital aborigines will win." The implication is that you don't have to suppress your child's love of digital products, let it go. Pulansky never limits what the 7-year-old son plays, and treats books, television, LEGO bricks , and video games as "one person." Although he thinks that some of his TV shows are "stupid junk", as long as the child loves to watch, let him see. He said: "We are living in a screen era, saying to the children, 'I hope that you read a book, hate you to see the screen' does not work. It can only reflect our own prejudice and preferences. It is just afraid of change, afraid of being eliminated. which performed." The editor of Atlantic Monthly, Rosin, tried to treat the 4-year-old son Gideon and the touch screen device in the manner of Pranski for half a year. Luo Xin put the iPad in the toy box with toys such as remote control cars and Lego blocks, so that the children can pick them at will. On the first day of the experiment, Gideon started playing the iPad at 8 o'clock in the morning and played for 45 minutes. Later, he played for a while every morning, from kindergarten to home, and before going to bed at night. After 10 days of this situation, his sense of freshness on the iPad disappeared and he was no longer fascinated. Treating the iPad is like other toys. After some days, he completely forgot that there was such a toy, and he had not touched it for about six weeks. Parents don't forget two principles In the book "Screen Time: How Electronic Media Affects Young Children," Ge Enqi puts forward the "3C Principles" to inform parents how to guide their children to touch screen devices. "3C" refers to content, context, and child. Gu Enqi believes that parents should help children choose the right content to watch, the time to watch the screen should be controlled, not to exceed the time the child communicates with parents and others, but also to provide guidance according to the specific circumstances of each child. Research by Larry Rosen, an American psychologist and education expert, shows that excessive child interaction with mobile devices can affect their creativity and imagination. Rosen suggested that parents arrange their children to play mobile devices on a 5 to 1 basis, that is, every minute of play, 5 minutes of other activities.
