In this study, 174 epidemic rumors from the list of epidemic rumors from Sina News and Catch Rumors column were used as the research object, and the rumor text was analyzed based on six analysis categories including content type, focus object, corroboration method, and so on. The study found that epidemic rumors are mostly “contagion” topics, which focus on the general public. Rumor texts are mainly expressed in one or two supporting ways and appeals. Narrative is the most common, with strong fear in the texts. On the basis of the above research, this paper summarizes the text strategies of rumor: they concoct topics based on the pain points of the epidemic, disguise facts to confuse the audience, and prefer exaggerated and polarized discourse styles. Finally, some suggestions are put forward.

The current situation of science popularization service in Chinese college and universities is lacking effective and applicable evaluation indexes. Based on the in-depth research of 25 universities in Jilin, Anhui and Zhejiang provinces of China, adopting Grounded Theory to conduct three-level coding for the survey interview content, the classification and theoretical model of the evaluation indicators are gradually established after the analysis and comparison of the co-word network. Then the three-level evaluation indicators are produced. The aim is to make a preliminary step in the evaluation research on the nationwide science popularization service in colleges and universities with the pilot demonstration, theoretical model, index system and operational tools.

In order to understand the topic selection scheme of domestic popular science journals in response to covid-19 pandemic, establish the pattern of selected topics during the pandemic, and provide some references, this paper uses the computational language method LDA topic model to compare the topic categories and contents of typical popular science journals on COVID-19 from January 2020 to January 2021, and then analyses the characteristics as well as shortcomings of the topic settings. This paper suggests that popular science journals need to enhance the innovation and depth of thematic content, systematically develop science thematic strategies based on the life cycle of an epidemic, increase the proportion of science news themes to promote the timeliness of science.

This paper attempts to investigate and sort out the science popularization policies issued by relevant departments and institutions in China, and analyze the contents of various policies about scientific and technical workers engaging in science popularization. Firstly, core keywords are extracted to draw the knowledge network map of policy content, focusing on the three processes of pre-stage, process and follow-up stage of science popularization. This paper summarizes the content elements framework of public science popularization policy from two aspects, and interprets each element in detail. Finally, the paper puts forward the prospect and suggestions for the future policy from the top-level design, cooperation mechanism, role positioning, content system, communication mode and other aspects in order to provide theoretical basis and decision support for the revision and improvement of science popularization policies.

Recently, Outline of the National Scheme for Scientific Literacy (2021–2035) has been issued. By analyzing the text of Outline of the National Scheme for Scientific Literacy (2021–2035), this paper finds out many new insights and solutions in the basic principles, goals, tasks, measures and policies regarding promoting public scientific literacy in China, while inheriting a lot from its predecessor and practical experiences in the past 15 years. It is stipulated that promoting public scientific literacy should take on a grand mission for the national economic and social development as well as global governance; it emphasizes the leadership for spirit and value at its top level design; it is more group-specific, has clearer tasks, and more precise measures in its promoting actions; it strengthens the foundation to transform scientific resources into popular scientific resources, and pays equal attention to normal and risk science communication in the infrastructure for public scientific literacy; it focuses on improvement of management mechanism, evaluation criteria and effectiveness.

Outline of the National Scheme for Scientific Literacy (2021–2035) gives different priority in orders to scientific spirit, scientific thought, scientific method and scientific knowledge, and defines the new connotation of scientific literacy by expressing citizens’ basic scientific ability as analysis and judgment ability and problem-solving ability. According to the new plan, more than 15 percent of the population will have scientific literacy in five years and 25 percent in 15 years. In order to achieve this goal, the new plan adds the elderly as the key group, adjusts the scope of the two key groups, modifies the content of the scientific quality to improve of the two key groups, and puts forward five measures to provide the supply efficiency of science popularization. The new plan is feasible, but there are still challenges of assessment the effectiveness of its implementation.

Adolescents are the reserve talents of national scientific and technological innovation. Improving the adolescents’ scientific literacy is necessary for realizing the high-quality development of the country. In the past 15 years, China has made great progress in creating an environment and providing resources for the development of adolescents’ scientific literacy, and Chinese adolescents have also achieved good results in international assessments. However, there are still some problems, such as low willingness of young people to engage in scientist career, insufficient attention to science education in schools, and insufficient connection between school and outside. To address these outstanding problems, the goal and corresponding measures of develop a large group of adolescents with scientist potential have been formulated. The promotion of scientist spirit should be the primary task, while giving full play to the role of formal school education as the main channel, actively exploring innovative talents’ training model, and laying a solid talent foundation for building national strength in science and technology.

Outline of the National Scheme for Scientific Literacy (2021–2035) strengthens the standardization of science popularization service as one of the guarantee conditions. By analyzing the current situation and existing problems of standardization of science popularization service, and according to the current situation and development requirements of improvement of national scientific literacy and science popularization work, the development strategies of standardization of science popularization service are put forward: doing a good job in the planning and overall coordination of standardization work during the “14th Five-Year Plan” period; building a multi-dimensional standardization system of national standards, industry standards, local standards, group standards, and corporate standards; formulating standards of science popularization product and services by classification; strengthening the publicity and implementation effect evaluation of standards; mobilizing social forces to participate in standardization work.

In the new development setup, modern science and technology museum system with Chinese characteristics should serve more effectively the all-round development of human being, leading the proper values, national development and social progress. The System should make reform and innovation in merging sci-tech and culture, infrastructure construction, content construction, operation mechanism and mode, building itself into the core bastion to support high-quality science popularization service system, making new contributions to the improvement of people’s scientific and cultural quality and the construction of innovation-oriented country.
