Job burnout is a central issue in contemporary occupational research. However, existing studies have paid little attention to the burnout levels and influencing factors specific to science-communication educators. This study employed a convenience sampling method using electronic questionnaires to collect data from 115 science-communication educators across 15 natural history museums in China. It investigates the overall burnout level within this group, characteristics of group differences, and associated influencing factors. The findings indicate that science-communication educators in natural history museums experience significant job burnout. Notably, higher levels of burnout were observed among educators working in first-class museums, those with permanent institutional positions (“bianzhi nei”), males, individuals aged 31~40, those holding intermediate professional titles, and those with a monthly income exceeding 10,000 RMB. Age, physical health status, perceived work pressure, and degree of social recognition were found to significantly impact their job burnout levels. Based on the empirical results, it is recommended that natural history museums implement tiered intervention strategies targeting high-pressure subgroups. These strategies should focus on optimizing work models to alleviate the educator’s physical and mental stress, enhancing social recognition to reinforce positive feedback, thereby effectively reducing burnout levels within this population.

Short-form video has emerged as a pivotal medium for the dissemination of emerging technologies, positioning technology enterprises as one of the main agents of science communication. Focusing on Unitree Robotics’ official Douyin account, this study draws on a sample of 81 videos and 4 114 comments to examine the interaction between corporate technological performance and public sociotechnical imaginaries. The study integrates multimodal discourse analysis with text mining to capture both the semiotic construction of technology and its discursive reinterpretation by the public. The findings reveal that embodied AI is rendered as a visualized, contextualized, and immersive technological performance through the orchestration of textual, visual, and auditory modes. Correspondingly, public discourse generates multiple, intersecting sociotechnical imaginaries structured around functional utility, techno-nationalism, and human-machine relations. These dynamics suggest that technological meaning is not unilaterally transmitted but continuously negotiated and stabilized through platform-mediated interactions between technology enterprises and the public. This study reveals that technological performance goes far beyond mere technology demonstration. It opens up a crucial space for the public to engage in the social construction of technology and to shape sociotechnical imaginaries. Consequently, these practices reconfigure science communication from one-way dissemination toward the participatory co-production of meaning.

This research takes the China Science and Technology Museum as the research object，and deeply studies how to use customer journey maps to enhance the audience's visiting experience. By analyzing the characteristics and behaviors of the audience，audience portraits were drawn. And then customer journey maps were created，covering the entire process of typical audiences visiting the China Science and Technology Museum. Results reveal that the customer journey map reveals the emotional fluctuations of the audience at key moments，especially dissatisfaction during ticket purchasing，dining，and leaving the museum. In response to these pain points，measures such as optimizing the ticket refund process，increasing dining space，and opening cultural and creative shops earlier were taken，and practice has proven that these measures effectively enhance the audience's visiting experience.Using customer journey maps to enhance audience experience is universal in the research of audience services in science and technology museums，and continuously iterated customer journey maps can provide support for improving the quality of audience services.

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.

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.

The primary school science education curriculum is the key focus for hatching students’scientific spirit and innovative quality in the new era. Looking at the historical development process，the curriculum policy of primary school science education from the beginning of the 20th century to now has experienced five stages：germination and attempt，foundation and exploration，adjustment and restoration，deepening and promotion，innovation and optimization，and has realized four transformations: In terms of value orientation，it has realized the transformation and regression from“instrumental value”to“intrinsic value”；in terms of target orientation，it has realized the iterative update from“serving social construction”to“developing scientific literacy”；in terms of content selection，it has realized the continuous improvement from“popularizing knowledge”to“comprehensive curriculum”. In the evaluation implementation，it has realized the gradual linkage from“one-way”education to“diversified”education. In the future，the standardization and innovation of the curriculum policy of primary school science education should insist on strengthening the overall planning and guiding the policy direction with a high position；Change the concept and practice，with the core quality as the guide to strengthen the moral and cultivate people’s goals；Pay attention to depth and integration，and promote the optimization and improvement of comprehensive course content；Pay attention to process and value-added，broaden the evaluation method and resource matrix.

High-precision scientific devices are an important part of high-end scientific research achievements，atomic clocks，as a key core device applied in the aerospace field，have been gradually known by the public in recent years，this paper takes the science popularization practice of atomic clocks research in Shanghai Institute of Optics and Fine Mechanics，Chinese Academy of Sciences（hereinafter referred to as SIOM）as a case study，and comprehensively examines the subject，form，content and basic features of the science popularisation of atomic clocks in SIOM.It is found that the team of scientists is an important force in promoting the popularisation of high-end scientific research results，immersive popularization is an important way，and national major scientific and technological strategies are an important opportunity. Based on the research findings，this paper proposes that the popularization of high-end scientific research results，such as large scientific devices，can be carried out in three aspects：enhancing the scientific popularization skills of researchers，improving the mechanism of popularization of high-end scientific research results，and cultivating a brand of popularization of high-end scientific research results. 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.

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.
