Scientific practice teaching in kindergarten is a kind of teaching activity that emphasizes the multi-dimensional participation of children’s behavioral practices，cognitive exploration and social interaction. However，there are a lot of phenomena that preschool teachers equate science education with common sense education and scientific inquiry with hands-on operation at present. There is a serious tendency of experience and subjectivity in teachers’scientific practice teaching. As a teaching mode based on evidence and facts，evidence-based teaching has attracted much attention because it can improve the rational and scientific level of teaching.This study firstly explains the theory of evidence-based scientific practice teaching in kindergarten，and then reconstructs the whole process of the development and implementation of scientific practice activities by adopting the mode of evidence-based teaching. It is found that the evidence-based scientific practice teaching mode of kindergarten built on the basis of the best evidence can be effectively applied to the scientific practice teaching of kindergarten，and provides a certain support for narrowing the gap between science education theory and teaching reality. It is recommended to strengthen specialized learning of scientific teaching text content，construct personalized scientific practice teaching guidance based on“Internet+”，and carry out clinical practice of evidence-based scientific practice teaching，in order to support evidence-based scientific practice teaching in kindergartens.

The Project on Grass-roots Science Popularization is the first science popularization special plan established by the state through central financial transfer payments. Since its implementation in 2006，the Project has focused on meeting the needs of grass-roots science popularization and solving the problem of“the last kilometer”of science popularization services. The results show that the Project on Grass-roots Science Popularization has experienced four stages of initiation，expansion，transformation，and deepening. The evolution of policy is characterized by the synergistic progression of both mandatory and induced elements，with central-local collaboration and social participation working in concert to continually achieve the dual goals of enhancing grassroots science popularization efficiency and promoting social equity. The process of policy evolution exhibits an intertwining of policy instrument innovation and path dependency，revealing structural contradictions in resource allocation efficiency and a pattern where policy effectiveness is constrained by the quality of institutional supply. Furthermore，we also construct a three-dimensional breakthrough pathway encompassing“institution-technology-society，”aiming to better realize the objectives of institutional change.

The research results provide useful references and thinking for scientific research institutions to make effective use of high-end scientific research results to carry out science popularization activities.

The international science and technology communication undertaken by Chinese overseas enterprises is significant for enterprise development and the construction of the national science and technology image. Currently，Chinese overseas enterprises have developed a certain awareness of international science and technology communication，particularly in fields such as infrastructure and heavy machinery，where their technological strength lays a solid foundation for such communication. These enterprises proactively build a communication network with overseas science and technology media and engage in exchanges and cooperation with local governments，associations，and universities to promote their products，technologies，and corporate brands. However，Chinese overseas enterprises face several issues in conducting international science and technology communication，including systemic risks in political and commercial public opinions，a lack of authoritative and professional support during communication，and a deficiency in storytelling from a native perspective. Therefore，it is necessary to enhance risk awareness，build communication communities，and provide theoretical and professional support to tackle these issues.

Science popularization short video creators play an important role in achieving high-quality development of science popularization and boosting the construction of Chinese modernization，while the role conflict aroused by the increasingly surging new technologies represented by AI makes them fall into different levels of role dilemmas. This study takes the Social Role Theory as the perspective，analyzes the specific manifestations of role conflicts among science popularization short video creators from both internal and external aspects of their roles，and further reveals the underlying causes that lead them to be trapped in“role conflicts”. To overcome the dilemma，science popularization short video creators should establish a correct view of science and technology，always adhering to the subjectivity of human beings in creation，returning to the essence of“content first”creation，and rationally use new technologies to empower creation and connect with a wider public group to create value under the guidance of laws，regulations，and industry norms. Only in this way can they maintain the vitality of their own role in the baptism of the times.

Artificial intelligence is driving an unprecedented revolution in technological tools and fostering comprehensive innovation in science popularization services. Serving as a tool for inspiration，content generation，round-the-clock monitoring，scene construction，positioning，data collection，and data processing，artificial intelligence has redefined the processes of science popularization creation，review，dissemination，and evaluation. It has significantly enhanced the efficiency，quality，scope，accuracy，and scientific rigor of science popularization services. However，the limitations of technological tools also introduce risks. These include the potential undermining of the authority and agency of science popularization personnel，the erosion of the foundational principles of science popularization services，and challenges to reinforcing their value orientation. Therefore，in the context of science popularization services，it is essential to enhance the understanding and proficiency of science popularization personnel in using artificial intelligence，regulate its application boundaries，and integrate value-driven rationality alongside technical rationality.

Digital competency of civil servants serves as the microfoundation for digital government construction. Building upon a critical analysis of digital competence-related concepts，this study clarifies the conceptual connotation of civil servants’digital competency. It is conceptualized as the comprehensive capability of civil servants to implement digital administration and governance within the digital government context. Its essential attribute emerges as a psycho-behavioral complex constructed through the interplay of public service motivation，public values，and digital technology integration. Drawing inspiration from classic competency models，this study develops a digital competency analysis framework for civil servants，encompassing psychological and behavioral competencies. The framework includes four dimensions：digital spirit，digital qualities，digital professional skills，and digital administration and governance capacity，which can be further decomposed into 15 specific elements. Ultimately，this study constructs a comprehensive digital competency evaluation index system for civil servants based on the proposed analytical framework.
