The continuous development of science education research is a necessary way to improve students' scientific literacy. On this basis, understanding the current situation and development trend of empirical studies plays an important role in the development of science education. The study constructs the analysis framework in four dimensions‘objective’, ‘evidence’, ‘conclusion’ and‘practical’, and summarizes the present situation of empirical study on science education both in quantity and quality dimensions through a systematic analysis of the empirical studies on the theme of conceptual change. The results show that the traits of the empirical studies are generally unfolded in the 2 aspects: (a) the improvement of attention and stability of quality under the longitudinal dimensions; (b) the imbalance between different horizontal dimensions. The analysis of the current situation and development trend will provide effective suggestions for promoting the empirical study of science education and provide some inspiration for the future development of science education in China.

Green WeChat Official Account is an important representative of social media on environmental communication. The text representation, discourse construction and communication mode of 100 000+ articles can concretely show the utility and construction of environmental communication. Framework and discourse studies demonstrate that the characteristics of green text are relevance, proximity and usability. Convenient aggregation, practical information, clear views and emotion are the important efficient ways of Green WeChat Official Account. It is more realistic to build “green public discourse space” than “green public sphere” in a social media. There is still a lack of scientific discourse, constructive ideas and green culture, which needs to be improved from information dissemination to value dissemination. It is an important way to establish a systematic modern green discourse system and guarantee the supply of value for “green public discourse space”.

The research analyzes Shanghai Science & Technology Museum, Changfeng Ocean World, Children's Museum, Insect Museum, Aviation Science Museum, Wind power Science Museum by using the six elements (Factor Conditions, Demand Conditions, Related and Supporting Industries, Strategy, Structure and Rivalry, Chance, Government) of Porter Diamond Model. The main advantages and disadvantages in the development of Science Popularization Industry are explored. Based on that, the research puts forward the main suggestions to improve the industry competition ability about Domestic Science Museum: Firstly, make the national support be in tandem with the science museum industry; Secondly, promote the supply side of the industry development of Science Museum; Thirdly, stimulate the demand side of public popular science consumption; Fourthly, build the PPP (Public Private Partnership) Model of Science Museum and Social Cooperation. Through the above-mentioned four suggestions, these are hoped that the ability of the Industry Development of Science Museum could be excavated to the maximum extent so as to promote the great development and prosperity of Popular Science Culture Industry in China.

With the development of science education, History, Philosophy and Sociology of Science (HPS) have become the focus of science education research, the educational value of history of science has captured more and more attention form science education researchers, especially its impact on the nature of science. Science museum is suitable for using the history of science to improve students' nature of science because of its rich resources, but the issue is lacking theoretical achievements. Firstly, the papers put forward the Framework for Activity of Science History Based on Exhibits (FASHBE), which may provide a guide for designing activity of history of science. Secondly, the case of electromagnetic was designed under the guide of the framework for primary school students. The Design-Based Research was applied to implement the case of electromagnetic three iterations so that we can revise it. We also used the questionnaires before and after case at the third implementation to measure and evaluate the educational effect of the case and the framework. The theory, the designing method, and the case are instructive for the design and implementation of the activity of history of science. It is helpful for history of science application in the school and science museum to improve individual's understanding of the nature of science.

By using the method of literature analysis, this paper systematically reviewed the relevant research literature of science popularization industry at home and abroad. According to different themes, the main viewpoints are classified into the definition of science popularization industry, the relationship between science popularization industry and science popularization, the classification and main forms of science popularization industry, the drivers and demands for the development of science popularization industry, the situation and existing problems facing science popularization industry development, as well as countermeasures and policy suggestions for promoting the development of science popularization industry. On this basis, the future research topics and prospects are put forward, and hoping to be helpful to the follow-up research.

As a fundamental national monitoring and evaluation investigation, Chinese civic scientific literacy survey has been in place for over 20 years. The paper gives a description and analysis of the general situation and main results of Chinese civic scientific literacy, the distribution of the civic scientific literacy in each provincial unit, public interest, information sources and involvement in Science and Technology (S&T), and public attitudes about S&T in general and specific S&T related issues. The survey provides the basic data and reference for the mid-term evaluation of the13th Five-Year Plan Citizens' Scientific Literacy Construction and related research fields.

Summarizing and reviewing fine experience of public science literacy is of immense importance to improve the overall science literacy in China. Mainly based on the achievements garnered for science literacy in China from 1998 to 2018, science literacy progress is divided into 3 major periods by adopting the principle of Delphi method, namely, Top-level design period, Government-led promotion period, Socially- mobilized period. Finally, the prospect of science literacy building is further discussed.

With an attempt to make a statistics and analysis of Science Popularization books published in 2015 from the number of the books published, disciplines distribution, translation, series number, pricing, page, publication and press, the author and the translator, total sales number and ranking, total sales amount, and ranking, the aim of the research is to have a comprehensive and in-depth understanding of the publishing and sales of science books in China. In recent years, the development of Science popularization books in China is encouraging, whereas, the old problems are still lingering on. On one hand, the type and quantity of printing are rising steadily, and the online sales are increasing rapidly. On the other hand, the old problems such as the repetition of topics, the single expression, the low number and sales of single books, and the gap between the average level of original books and the imported books still restrict the development of Science Popularization books.

With the development of social economy and urbanization in China, the phenomenon of “Not in my backyard”(NIMBY) represented by waste incineration and PX (Para-xylene) projects has occurred from time to time in China, as a result, public engagement in scientific dialogue has become quite necessary. In the study, two dialogues arranged in a formal conference room and a cafe may respectively provide some practice for exploring scientific dialogue mechanisms among experts, enterprises, government departments and the public. The comparative analysis of the two dialogues showed that the speaking frequency per unit time of the latter increased by 27% over the former; experts in the former occupied nearly half of the speaking time, while the latter dropped to 38%, the proportion of other representatives' speaking time increased in varying degrees; the average speaking frequency and volume of men in both dialogues were higher than those of women; the former was more similar to “answering reporters' questions”, while the latter relatively fully expressed their respective views. Finally, it briefly introduced the research of several modes of participation in Germany, and pointed out the main challenges for scientific dialogue to provide some reference for further practice.

The imbalance between science popularization and scientific innovation still exists in China currently, albeit the central government emphasize the importance of scientific popularization. We suggest setting up a trial credit system in colleges and universities to encourage graduate students to attend activities of popularization of science and promote the construction of science popularization talent. Colleges and universities are important intellectual resources centers for activities of popularization of science, thus it is of practical significance to carry out credit system for in colleges and universities by combining domestic and foreign experience. Moreover, we should also be aware of the differences between the education system and the popular science system. We need to think deeply about the problems that may arise and work them through earnestly.

With the rapid development of Internet economy and urbanization of “intelligence” is being accepted by more and more countries and the public. The paper takes the framework and application of the APP service and management platform (it belongs to the construction of digital operation and management system for zhejiang science of technology museum and has been in operation for nearly one year) as an example. In line with commonalities of the routine operation service and management pattern, visitor terminals are designed for the public, and management terminals are designed for the working staff. The paper also comes up with some ideas concerning how to apply digital services to the operation of science popularization venue and make it develop in a sustainable way.

In the 1950-1977 National General Bibliography, 110 chemical popular science books were included. At first, many books were translated books from Soviet. After that, Chinese originals gradually picked up increase. Following the surging of slogan “marching towards science”, the number of books rose dramatically. Due to various political movements in the 1960s, the number began to decline. And then it rebounded in the middle and late period of “Cultural Revolution”. The Hundred Thousand Whys was the largest encyclopedic popular science book published during that period, it was published in three editions, and the chemical part had five volumes. During the “Cultural Revolution”, the number of chemical popular science books was very small, mainly used to interpret Marxism-Leninism and assist political struggles. The content of the chemical popular science books from 1950 to 1977 focuses on the most basic chemistry knowledge, mainly comprehensive knowledge, common substances and phenomena, carbon and organic matter.

As an important carrier of astronomical science popularization, the publishing development level of astronomical science books rightly reflects the breadth and depth of astronomical science work. At the same time, the number and quality of astronomical science books published in a certain historical period can also reflect the level of astronomical development in a country at that time. The paper makes a statistical analysis of the publishing of astronomical popular science books from the birth of New China to the end of the “Cultural Revolution”, and subsequently summarizes the advantages and disadvantages of the publication of astronomical science books during that period. It is of great theoretical and practical significance to promote the publication of contemporary astronomical popular science books in China and even the development of science popularization as a whole.
