In recent years, driven by national and industrial policies, A group of children's guardians, seven colors of light: a journey through Mars, wonderful animals and good animal partners (Season 3) have emerged And other popular science programs for children, from focusing on social hot spots and selecting the most valuable popular science topics, to strengthening creativity and science and technology drive, turning boring into interesting, and then spreading the scientific spirit to the whole society... These programs seek a new breakthrough in the existing model of "children + popular science" in terms of content, form and communication, and have achieved high social evaluation and communication effect. Zhou Kui, associate professor of Communication University of China, said: "these programs are both informative and interesting. They can greatly stimulate children's interest in seeking knowledge, transfer scientific knowledge, carry forward scientific spirit, and effectively help the popularization of science by means of art. It is a new exploration of children's popular science programs." Focus on children's perspective and narrow the distance between children and science In the past, children's popular science programs were often labeled as "rare" and "obscure". If we want to give full play to the educational function of popular science programs and improve the attraction and social value of program content, it will naturally become the primary task of creation. Therefore, children's popular science programs should start from children's perspective, interpret scientific principles from daily life, make boring knowledge lively and interesting, and stimulate children's interest in science. How does popular science enter the world of children? The key point is to choose attractive content and answer the questions they are curious and want to know. For example, focusing on the theme of natural science popularization that children are interested in, "wonderful animals" provides children with rich natural knowledge in the kingdom of science popularization created by the program with a number of interesting knowledge points related to animals, from the sky to the sea, from glaciers to rain forests. With "interactive Animal Science Popularization" as the main line, good animal partners (Season 3) allows children to start an adventure under the leadership of Mr. ladybug, which fully meets their thirst for knowledge. According to Liu liming, an associate researcher of the school of communication and design of Sun Yat sen University, "popular science programs should not only realize the function of teaching in fun, but also take into account social values and highlight humanistic care". It is not difficult to see that many programs closely combine knowledge popularization with social hot spots, so that the content takes into account children's preferences without shutting out parents, breaking the limitations of program communication and effectively maximizing the communication population. For example, the seven color light · a journey through Mars launched by Kaku children's channel takes the successful landing of China's "tianwen-1" on Mars as the starting point, and comprehensively popularizes Aerospace knowledge in the process of exploring the mysteries of Mars with children; Another parenting service program, mother raising a baby, innovatively launched the epidemic prevention knowledge section to answer the questions closely concerned by parents such as how to spread the virus and how to wear masks correctly, so as to provide parents with scientific parenting programs in extraordinary times. In addition, the guardian of children created by CCTV network takes children's physical and mental health as the starting point, and the topics involve children's healthy lifestyle, common diseases of children, vision protection of children, etc., to help parents and children stay away from anxiety and grow up healthily. Deng Dong, director of children's Education Department of CCTV network and initiator of "children's Guardian", said, "A good popular science program for children should become a Science Reader full of wisdom. It should not only give full play to the due meaning of the topic of popularizing scientific knowledge, but also constantly explore a wider audience, observe the common improvement of scientific knowledge of several generations, and narrow the distance between them and Science in positive intergenerational interaction". Teaching in fun, novel form, promoting children's Science Popularization The expansion of content also brings the diversified expression of the program. Children's popular science programs need to think from the perspective of children, combine scientific knowledge with entertainment elements, spread knowledge from the perspective that is easy to be accepted by children, find the best balance between popular science programs and children's programs, and explore a new way of teaching in fun while enhancing the effectiveness of knowledge transmission. As children's audience, their perspective and understanding ability are quite different from that of adult audience. When the content is combined with vivid and interesting forms of expression, the attractive visual effect of the program can naturally achieve the ultimate expression of the content. For example, the use of sitcoms can effectively break the time and space constraints and let children take the initiative to open the door to explore the scientific world, which has become one of the commonly used expressions in many programs. "Seven colors of light · human health roaming" vividly popularizes health knowledge by means of interesting sitcoms, and children start a novel and interesting safe learning journey in the animated micro world of human body. Zhou Kui believes that "in this way, the attraction and viewability of children's science popularization programs are greatly enhanced. Children are no longer just the audience in front of the screen, but become a member of the story, participate in the whole story, and their thinking ability and practical ability are also improved". In addition to pursuing the balance between the popularization of scientific knowledge and vivid interest, some programs also explore the popularization and popular expression of content on the basis of meeting their own program characteristics. For example, children's Guardian invites authoritative experts in the field of children's medicine to form a professional "Guardian" team. In the program, "Guardian" combines vivid and typical pictures and examples, and uses popular and humorous language to provide authoritative and practical suggestions for children in different situations. Deng Dong said, "the program form of 'Guardian' speech sharing integrates the rich experience and personal charm of guests, which can greatly stimulate the dissemination effect of scientific parenting experience". On the basis of ensuring the authenticity and preciseness of the content, the current batch of popular science programs for children highlight the significance of interest, interaction and education, guide children to actively learn scientific knowledge, stimulate children's imagination when watching the programs, and create knowledge platforms to cultivate curiosity and scientific thinking ability. According to Huang Hua, an associate professor at Fujian Normal University, "If a popular science program for children is not innovative in form and exciting in content, it will not be able to attract children's attention, and it will be difficult to popularize scientific knowledge and lead them to explore science and understand the world." The popular science program for children, represented by, has sparked the spark between science and childlike innocence, with bright spots in form and interesting content, and achieved the purpose of "teaching in fun and learning through fun". Spread the scientific spirit and illuminate the world of children's knowledge The significance of popular science programs is not only to show and spread scientific ideas, but also to convey the scientific spirit, thinking and belief to the audience through the programs by stimulating the interest of the whole society in science. He Tianping, a postdoctoral fellow in sociology at Renmin University of China, said, "in the process of creating popular science programs for children, we not only need to pay attention to expressing the content in the way of teaching in fun, but more importantly, we need to achieve the purpose of education, achieve the combination of 'interesting' and 'meaningful', and infect children with the spirit of science". Excellent popular science programs should focus on the overall situation, shoulder not only the task of popularizing scientific knowledge, but also become the carrier of establishing and disseminating scientific spirit to the whole society, and boost the "Chinese dream" with the "science and technology dream". "Seven colors of light · a journey through Mars" comprehensively introduces the basic structure, exploration mission, operation process and other contents of "tianwen-1", shows the tortuous and rich exploration process of China's aerospace industry from the side, has the deep value of publicizing China's aerospace industry and carrying forward the aerospace spirit, and imperceptibly enhances children's national identity and national self-confidence. Good animal partner (Season 3) integrates many Chinese traditional cultural elements such as paper cutting and lion dance, adapts a large number of excellent Chinese folk stories, idiom stories and traditional fairy tales into cartoons, highlights the unique charm of Chinese culture, and realizes the inheritance of Chinese traditional culture in popular science. In the all media era, with the continuous renewal of information communication channels, higher requirements are put forward for science popularization. The current popular science programs for children have also begun to try a new exploration of integrated communication, using large and small screen linkage and making full use of new media platforms to form a powerful online and offline communication matrix. For example, the children's guardian is a lightweight program with 15 minutes per program, which is short and short, and is broadcast synchronously through the new media platforms such as micro-blog WeChat official account. This is a good match for the current fragmented viewing features, and makes science content better embedded in real life. "A strong youth makes a strong country, and a wise youth makes a wise country". Children's guardian, seven colors of light: a journey through Mars, seven colors of light: a journey through human health, wonderful animals, good animal partners (Season 3) And other popular science programs for children, constantly innovate in content, form and communication, both scientific and viewable. In terms of expanding vision and improving knowledge literacy, they cultivate children's knowledge and interest in science, and illuminate children's knowledge world. He Tianping said, "in the future, we need more high-quality popular science programs for children in the new era, and gradually form a good atmosphere for the whole society to speak, love, learn and use science in a professional and interesting way.".
