[目的/意义]现阶段很多图书馆都出现了空间不足、环境老化的现象,空间再造成为图书馆的一个迫在眉睫、亟待解决的重大课题。[方法/过程]根据图书馆空间五要素要求原则,从读者属性角度分析图书馆空间短缺的原因是来自读者对图书馆空间的需求差异,把握读者属性的特点才能更好的进行空间再造。[结果/结论]针对不同类型的图书馆给出有效改善图书馆空间紧缩或阅读空间空置率高等现状的相应思路。  相似文献

[目的/意义]培育读者的创客素养是发展读者核心素养的关键之一,通过提出培育创客素养的有效途径,为在创客时代提升读者创客的创客素养提供借鉴。[方法/过程]基于创客素养教育涵义的分析,对创客素养包含的创客意识、创客道德、创客能力、创客技术和创客精神5个方面内容进行阐述,提出图书馆应通过采取转变思维观念、打造创客环境、渲染创客空间范式、培育不同创客DNA、支持组建创客团队等8种培育创客素养的途径。[结果/结论]图书馆应把握好双创教育的发展态势,正确实行空间再造,积极开展创客活动并实施创客素养教育,真正担当起双创教育的职责,为构建良好的校园创客文化做出贡献。  相似文献

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning.  相似文献

随着信息和人工智能等技术的发展,"智媒时代"正在加速来临,智能化、场景化、共享化成为内容传播的三大趋势,图书馆与用户、内容的关系也将重新连接、深度交互。作为推广"全民阅读"重要阵地的公共图书馆,已经迎来了发展和变革的重要时间节点,以人、馆和资源之间的智能互联为特征,公共图书馆的运营模式、服务转型和空间生态都在发生深刻变化,一切职能转型和服务创新都必须围绕用户的需求和体验进行,进而成为提供智能化、泛在化、人性化服务的——"智慧型"第三文化空间,实现从"书的图书馆"到"人的图书馆"的终极跨越。  相似文献

This article introduces emergent memory, a conceptual extension to rhetorics of public memory, to describe memory’s genesis in sites built without commemorative commitments. Examining Detroit’s “8 Mile Wall,” a site built to reinforce segregated housing, this project argues the rhetorical tenets of emergent memory present in this space. As a relic of segregated history, the wall symbolically recalls the city’s controversial past, but has recently been the subject of a local mural project to redefine the wall’s purpose. Some consider this a step toward reclamation, as it visually repositions the disturbing remnant. For others, the murals simply cannot overwrite troubling memories of the city’s discriminatory history. This essay uses emergent memory to describe how the wall’s complicated mnemonic legacy simultaneously harkens to a difficult history and how the mural additions use that same legacy to convey an optimistic future for Detroit and those marked by this urban space.  相似文献

The promotion of students’ achievement and competence in the so-called STEM disciplines is one cornerstone of current educational research and practice. In particular, as early as elementary school, the fostering of an adequate understanding of science is a normative goal of science education. It facilitates students’ science learning and enables them to understand the nature and development of scientific knowledge. Based on the relevance of the promotion of young children’s understanding of science, a corresponding science intervention was recently developed and successfully evaluated in a first study under highly controlled conditions. The goal of the present study was to investigate the effectiveness of this intervention when implemented in practice. One hundred seventeen third- and fourth-grade students and 10 trained course instructors participated in this study. We applied a randomized block design with waitlist control groups and repeated measures. The results revealed that children assigned to the intervention compared with children assigned to the waitlist control group showed better inquiry-related methodological competencies (a better understanding of the scientific inquiry cycle and experimentation strategies) and a higher need for cognition. The findings point to the successful implementation of the intervention and are compared with the results of the first study.  相似文献

休闲是科学诞生的基本条件之一。作为时间形态存在着的休闲(闲暇时间)是物理学创造活动得以进行的基本保证,而作为实践形态而存在的休闲则极大地推动了物理学的突飞猛进,并通过技术的中介,给人类社会带来了高度的物质文明和精神文明,反过来在延长了休闲时间的同时,又丰富了休闲的内容与方式。在当今知识爆炸时代与信息化时代,无论是对任何一门学科的教学而言,学校主管部门特别是具体授课者,都应该力求做到得心应手地给学生"留下空间"。因为只要有了空间,学生就不仅能够在积极向上、形式各异、多姿多彩的校园文化这个心灵的驿站中,获得精神的慰藉,从而陶冶了情操、恢复了体能、增强了交际能力;而且还能够充分利用课余的闲暇时间,在开放性、交互性、共享性、协作性和自主性的信息化环境中,积极主动地去猎取适合发展自己个性特长的有关知识,进而使他们的知识结构,能够跟得上新知识、新学科与日俱增的时代步伐。  相似文献

ABSTRACT

Introduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required.  相似文献
