科技人力资本视角下杰青科学家资助年龄对资助效果的影响——以杰青基金地球科学项目为例     

田人合  郑军卫  张志强  于洁  杨芳娟 《图书情报工作》2019,63(22):91-105

[目的/意义] 杰青基金实施25年来，资助者年龄呈大龄化趋势发展，深入分析该现象对完成杰青基金的影响，对未来杰青基金管理具有重要意义。[方法/过程] 研究以1994-2018年杰青基金地球科学项目为研究对象，构建科研论文产出效率、创新能力和学术影响力三个评价指标，提出"科技人力资本投入-科研产出"理论模型及假设，采用DID模型克服样本选择性偏误所导致的内生性问题，验证理论假设，实现对杰青基金资助年龄异质性的研究。[结果/结论] 实证结果表明：杰青科学家大龄化趋势日趋严重，存在明显的45岁现象；杰青基金实施20年中，支持"资助年龄越大，资助效应越好"假设的比例较低；三个评价指标维度，资助效应最大且资助年龄在39-42岁之间的年份在杰青基金实施20年中所占比例最大。因此，无论从杰青基金设立宗旨、还是从评估结果来看，都应该避免杰青科学家大龄化趋势，扩大对中低龄优秀青年人才的资助。  相似文献

魏海霞  吴晓川 《图书情报工作》2019,63(18):47-53

[目的/意义]针对我国高校图书馆社会化服务效果不佳的状况，试图寻找一种有效且能长期开展的模式，以促进高校图书馆广泛参与，更好地满足民众的文化需求。[方法/过程]以西华师范大学图书馆为例，从组织构建、运作模式、社会效益概述科普基地社会化服务模式，并分析该模式具有构建约束机制、资源保障机制与激励机制、服务渠道的畅通机制的优势。[结果/结论]在自愿的原则下，高校图书馆与省委宣传部、省社科联联合共建科普基地以开展社会化服务，通过经费多家出，协调搭台，借用科普基地完善的管理体制与运行机制，构建高校图书馆社会化服务的长效机制。科普基地工作已在全国广泛开展，高校图书馆作为重要的文化服务单位位于申报对象之列且容易具备申报条件。因此，科普基地社会化服务模式是一种灵活的、有效的、可操作的，且具有广泛参与机制与可持续的模式，值得推广。  相似文献   

安全情报概念的由来、演进趋势及涵义——来自安全科学学理角度的思辨     

王秉  吴超 《图书情报工作》2019,63(3):45-53

[目的/意义]安全问题是当前国家、政府、企业、社会、大众及学界广泛关注的一个重要现实问题，而安全情报是保障安全的必用之宝，故安全情报研究具有十分重要的理论与现实意义。[方法/过程]运用文献分析法和思辨法，从安全科学学理角度出发，论证基于安全科学视角解读与界定安全情报概念的必要性、重要性与紧迫性，探讨安全情报概念的由来与演进趋势，并分析安全情报的涵义。[结果/结论]从安全科学学理角度看，从安全信息到安全情报的安全管理新认识是提出安全情报概念的根本动力，安全情报概念的总体演进趋势是从分散到统一。同时，从系统安全学角度看，安全情报是指所有影响系统安全行为的安全信息。  相似文献   

The impact of student misconceptions on student persistence in a MOOC     

Chen Chen  Gerhard Sonnert  Philip M. Sadler  Dimitar Sasselov  Colin Fredericks 《科学教学研究杂志》2020,57(6):879-910

Massive Online Open Courses (MOOCs) provide opportunities to learn a vast range of subjects. Because MOOCs are open to anyone with computer access and rarely have prerequisite requirements, the range of student backgrounds can be far more varied than in conventional classroom-based courses. Prior studies have shown that misconceptions have a huge impact on students' learning performance; however, no study has empirically examined the relationship between misconceptions and learning persistence. This study of 12,913 MOOC-takers examines how students' misconceptions about the upcoming course material affect course completion. Using a survival analysis approach, we found that, controlling for the score in a pre-course test, students holding more misconceptions had a higher dropout rate at the start of the course, an effect that diminished over time. Other student variables were found to have a positive impact on survival that persisted throughout the entire course: U.S. location, higher age, an intention to complete, better English skills, prior familiarity with the subject, motivation to earn a certificate, and score and time spent on the previous problem set (homework). By contrast, student gender, education level, number of previous MOOCs completed, and motivation to participate in online discussion forums did not affect survival.  相似文献   

“I'm just not that great at science”: Science self-efficacy in arts and communication students     

Eileen McBride  W. Wyatt Oswald  Lindsey A. Beck  Amy Vashlishan Murray 《科学教学研究杂志》2020,57(4):597-622

Research in science education confirms the importance of self-efficacy in students' persistence and success in the sciences. The current study examined the role of science self-efficacy in nonspecialist, arts and communication-oriented students encountering science in a general education context. Participants (N = 275) completed a beginning- and end-of-semester survey including a Science Self-Efficacy Scale, a “connection to science” measure—the Inclusion of Science in Self Scale—and a Science Anxiety Scale. Participants also responded to two open-ended “sources of science efficacy” questions, and provided background/demographic information and access to their academic records. Results showed a significant increase in science self-efficacy and connection to science—although no change in science anxiety—over the course of the semester. The observed shift in self-efficacy for minority and international students was of particular note. These students started the course with lower confidence but, by the end of the semester, reported comparable science self-efficacy, and achieved similar grades to their White/Non-Hispanic and US resident classmates. Contrary to expectations, science self-efficacy did not predict performance in the class. However, students' self-reported sources of efficacy indicated increased confidence in using science in daily life, and confirmed the value of mastery experiences and of personally meaningful, student-centered course design in scaffolding student confidence. Results are discussed in terms of the individual and instructional factors that support science self-efficacy and student success in this unique, general education science environment.  相似文献   

University reform and the development of social sciences in Indonesia     

《International Journal of Educational Development》2020

Much has been studied regarding university reforms and their impacts on scientific development worldwide. This paper aims to enrich current perspectives on university reform by developing a distinct concept of social science development in the context of the emergence of academic social sciences in Indonesia. Using a bibliometric method, this paper finds a significant increase in the volume of international scientific publications focusing on socio-economic and political issues. However, two issues that presently color the landscape of social scientific publications are the bifurcation of academic dependencies and limited extension of Western social theories. The future of the social sciences in Indonesia will be determined by interrelationships between the state, universities, and networks of academics who can address the former issue and ensure that academics publish in mainstream international journals emphasizing the prominence of the latter. In doing so, the social sciences will have the potential to improve future university teaching and engagement in public policymaking in Indonesia.  相似文献   

Drawing to reason and learn in science     

Russell Tytler  Vaughan Prain  George Aranda  Joseph Ferguson  Radhika Gorur 《科学教学研究杂志》2020,57(2):209-231

Despite mixed results in research on student learning from drawing in science, there is growing interest in the potential for this visual mode, in tandem with other modes, to enact and enable student reasoning in this subject. Building on current research in this field, and using a micro-ethnographic approach informed by socio-semiotic perspectives, we aimed to identify how and why student drawing can contribute to student reasoning and learning. In our study, secondary school students were challenged to explore and collaboratively create explanatory representations of phenomena including through drawing. Data were generated using multiple wall- and ceiling-mounted cameras capable of continuously tracking groups of students negotiating these representational challenges. Our analysis proceeded through active and iterative viewing of the extensive video record, and the identification of themes to establish possible relationships between drawing and reasoning. Through this process, we (a) identify multiple necessary conditions and varied opportunities for student drawing to enact and enable reasoning, and (b) extend current understandings of how the particular affordances of this mode interact with these conditions to contribute to student learning in science.  相似文献
