A new standard for children to be "smart"
How Smart our children are? In recent 10 years, most of the parents who have done intelligence tests for children in hospitals are happy: their children are super smart, but at a cross-strait three symposium that ended yesterday in the Zhuhai division of North Normal University, Zhang Houcan, a professor of psychometrics and a psychology professor at Beijing Normal University, said: "this measurement is extremely inaccurate."
Mr. Zhang Houcan, who presided over the second edition of the American Wechsler's children's intelligence scale in the United States in 1986, has been used in China until now. The norm established by Chinese children has never been updated. According to the internationally recognized "Folin effect", human intelligence increases 3 points every 10 years. This is equivalent to comparing the children of today with those of the 80s of the 20th century. Li Yuqiu, a professor of psychology at the University of North Normal University, Zhuhai, said that the second edition of the Wechsler was actually a product of the 70s in the United States, which was rather rough and only a total IQ. Later, the fourth edition of Merriam Webster contained 14 sub tests, showing children's abilities more accurately.
in 2006, with the participation of Mr. Zhang Houcan, a large number of experts from China took part in the introduction of a large number of human and material resources in the fourth edition of the Wechsler child intelligence scale, and revised the Chinese version. From the south to the north, from the east to the West, from the city to the countryside, 1100 samples were sampled from each industry to 6-16 years old in China. Standard sample for children (Chang Mo). The revised version of the fourth edition of the Wechsler Intelligence Scale for children was passed in 2008.
Li Yuqiu said in an interview with the Yangcheng Evening News reporter that "teaching students in accordance with their aptitude" has been said for more than two thousand years, but what kind of material is not scientifically judged. The real intelligence measurement in the world was invented by the French Binet in 1905. He used the Chinese examination method for reference. At that time, it was not called intelligence quotient, but also called "intelligence age". In 1916, Stanford University revised the Binet intelligence scale, using intelligence quotient "IQ" to show intelligence level. The internationally recognized authoritative intelligence scale is the Wechsler scale and Standford's scale. Although intelligence tests are applied in China, most of them are based on Problems and are seldom used in Peiping. Overseas and Hong Kong and Macau are widely used in schools and kindergartens to help children with weak learning ability. Chinese parents are very keen to let their children learn a skill or a tutor for a tutor, but they are blind. They are not clear about their children's strengths and weaknesses. What is suitable for learning and how to learn? The children's performance is not good, but what is weak and weak? In fact, even if two people have IQ, he Our strengths and weaknesses are different. We should have different learning methods. Some people are highly intelligent, but life is not successful. Some people are very intelligent, but they are quite successful. The Wechsler intelligence scale can detect the differences in each person's ability, or what to avoid, or what to make up for? Zhang Houcan believes that a missing piece, through a targeted training, needs to be added to the average level and to strengthen its strengths.
in the fourth edition of the Chinese version of the Wechsler's children's intelligence scale, Mr. Zhang Houcan drew some interesting conclusions:
between 1986 and 2006, the intellectual level of Chinese children increased by 12.84 points, far exceeding the "Fulin effect" of 3 points per 10 years, and there was no difference between male and female. In the same period, the intelligence level of children in Hongkong increased by 8.49 points, and Taiwan did not change much. The United States is 2.91 points, close to the "flint effect". Zhang Houcan explained that the development of children's intelligence level is directly proportional to economic development and educational input. In the past 20 years, China is in an upward stage, with the development of economy, medical conditions, education level and nutrition will all be good, which will affect the intelligence development of children. During this period, China's GDP grew by 39 times, the university increased 3 times, and the student scale expanded 10 times. The foundation of Hongkong and Taiwan is different from that of the mainland of China. Their rapid economic growth was in the 70-80 century of the last century.
the intelligence development of children in eastern and Northern China is significantly higher than that in the central and western regions, and the worst in the western region. The total IQ in
