"I calculated that the number of times I took the initiative to ask the teacher no more than 5 times in the last semester, whether online or offline." During the winter vacation, Jiahui (alias), a senior high school girl, summarized the study of the semester just ended. "I have met many children and found that the older they grow up, the less willing they are to ask questions. Primary school is the most curious period," said Li Xingda, a postgraduate student of the Institute of Science and Education of Beijing Normal University. Many experts have also paid attention to the problems found by Li Xingda. Li Xiangdong, dean of the School of Astronomy and Space Science of Nanjing University, once said in an interview with the reporter of China Youth Daily and China Youth Network, "Every child has an astronomical dream in his heart. When he looks up at the stars, he will have endless reverie. This is the curiosity engraved in our genes. But many people in the living and learning environment, such dreams and curiosity will gradually fade". Scientific and technological progress depends on innovation, scientific and technological innovation depends on talents, and talents need to be trained from childhood. This concept should have become a consensus. However, why does children's scientific curiosity "engraved in genes" diminish with age? Is it the policy reason? For a long time, China has attached great importance to science education. As early as 2001, the "nature" course in our primary school was changed into "science" course; In 2017, China revised the Primary School Curriculum Standards for Compulsory Education and promulgated a new high school curriculum standard; In 2021, China released the Outline of the Action Plan for the Scientific Quality of the People (2021-2035); In 2022, China revised the Science Curriculum Standard for Compulsory Education, which clearly stated "protect students' curiosity and stimulate students' internal motivation to learn science" in the 2022 version of the curriculum standard. The top-level design has been clarified, so we need to find the answer from the operational level. The reporter of China Youth Daily and China Youth Network recently interviewed many experts and scholars to explore the reasons why children lost their curiosity about science and try to find the answers to the problems. The curiosity of children is consumed in the endless brushing of questions. "In fact, no matter in which country, the curiosity of children will decrease with the increase of age, because they will focus more and more on a certain field, and will no longer ask questions about what they are accustomed to." said Luo Xingkai, a professor of Guangxi Normal University and vice chairman of the Basic Education Science Teaching Steering Committee of the Ministry of Education. Although it is a common phenomenon that curiosity will decline with age, there are some exceptions. "They can see problems in the phenomenon that people are accustomed to, put forward and find ways to solve them. So scientists are grown children," Luo Xingkai said. Curiosity is indeed an important driving force on the road to scientific research. However, the decline of curiosity of Chinese children is particularly obvious. "For a long time, China's education has not gone out of the talent training mode centered on knowledge transfer." Zheng Yonghe, president of the Institute of Science and Education of Beijing Normal University, pointed out the reasons behind. The training mode centered on knowledge transfer will inevitably put the knowledge system into knowledge teaching, and then enter the "teaching practice test" routine, plus "heavy test" and "heavy score"
