Creativity development in preschoolers: The effects of children’s museum visits and other education environment factors     

《Studies in Educational Evaluation》2020

As one of the potential contextual factors for creativity development, children’s museum has been introduced to China from the western world in recent years, with the aim to offer a new informal educational environment to enhance children’s creativity. Based on experimental data for two groups of 4-year-old preschoolers (218 for the family mode and 202 for the preschool mode) from Beijing with an appropriately one-year long intervention (September 2017 to July 2018), this study examines the effect of regular visits to a children’s museum and other education environmental factors on young children’s creativity measured by Torrance’s Thinking Creatively in Action and Movement (TCAM) test. Results indicate that in terms of family visit, compared to the control group, the intervention that offers 18 times free tickets to visit a children’s museum significantly improved the experiment group’s originality (a sub-measure of creativity) by an additional 34.51 %. A beneficial effect of this intervention was also found in improving children’s fluency from the sample of preschool group visit (46.80 %). In addition, family education environment factors such as public preschool attendance, frequency of visits to science museums, and the degree of parents’ latitude were also found to positively affect creativity. Children’s personal features such as sex and geographic location of the family are also found to be related with children’s creativity.  相似文献   

Efficacy of using non-linear pedagogy to support attacking players’ individual learning objectives in elite-youth football: A randomised cross-over trial     

Simon J. Roberts  James R. Rudd  Matthew J. Reeves 《Journal of sports sciences》2020,38(11-12):1454-1464

ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献   

一种旧的新逻辑:实质归纳理论     

李帅 《科学技术哲学研究》2020,37(1):20-26

诺顿在古德曼和亨普尔等人的启发下,结合他的科学哲学研究背景,提出一种不同于他所定义的“形式归纳理论”的“实质归纳理论”,强调归纳的局部应用性,拒斥普遍的归纳推理模式。归纳推理的基础往往建立在具体领域的事实之上,因此所有的归纳推理都是局部的。诺顿认为归纳推理模式是由事实授权的,我们可以通过考察这些事实的可靠性来评估归纳风险。同时实质归纳理论不再区分归纳的事实部分和模式部分,所以不易受休谟问题的影响。但我们发现,诺顿的归纳辩护面临着亟待解决的问题,其理论也遭受多方面的批评。实质归纳理论是归纳逻辑领域的前沿性成果,引起了逻辑学界和科学哲学界的广泛关注,一定程度上体现了归纳逻辑的强劲生命力和广阔的发展前景。  相似文献

Towards an expanded cognitive developmental science understanding of human teaching / Hacia un conocimiento ampliado de la enseñanza humana basada en la ciencia del desarrollo cognitivo     

Sidney Strauss 《Infancia y Aprendizaje》2018,41(3):447-490

Teaching is one of nature’s remarkable inventions. Despite over two millennia of academic discussion about teaching, it remains in need of a broad scientific footing. The cognitive and developmental sciences, writ large, are candidates for such a footing. The purpose of this article is to go beyond teaching as knowledge transmission and present an expanded cognitive developmental account of teaching’s remarkable complexity. A minimalist and maximalist approach for describing teaching are presented, with a preference offered for the latter. It can serve as a map for backward engineering so as to get to the origins and developmental trajectories of the map of teaching’s components. An expanded mind-to-mind coupling version of the complexity of normative adult teaching is presented which includes stage-setting with emotion-, motivation- and mind-reading, organizing teaching sessions, scaffolding, detecting knowledge gaps and intervening by knowledge transmission strategies intended to reduce the gaps. In a backward engineering move, research is presented on infants’ abilities for some of what is presented for adults. Teaching is also prosocial, with heart-to-heart coupling. It is inextricably intertwined with teaching, and is another part of teaching’s complexity. Teaching’s prosociality is analysed via the economic concept of non-rivalry. It is shown that teaching is a form of helping behaviour but is not altruistic. Directions for further work in this maximalist approach to the scientific study of teaching are presented.  相似文献

研发费用加计扣除是否提升了企业创新能力?——创新链全视角          下载免费PDF全文

冯泽  陈凯华  戴小勇 《科研管理》2019,40(10):73-86

现有关税收优惠政策对企业创新活动影响的文献缺乏从整个创新链的全角度揭示税收优惠政策是否真正提高企业创新能力的探索。基于中关村科技型企业数据，本文选取税收优惠政策中典型的政策工具“研发费用加计扣除”作为研究对象，有别于已有主要从“投入”视角关注研发费用加计扣除引导作用的研究，从“投入-产出-收益”的创新链全视角，将创新过程分为技术研发阶段与技术转化阶段，以揭示研发费用加计扣除政策是否真的提升了企业创新能力。基于PSM-DID方法的实证研究结果发现：在投入端，研发费用加计扣除政策显著提高了企业的研发投入规模与强度；在产出端，研发费用加计扣除政策仅促进了研发产出规模的提升，而对于产出强度则无显著影响；在收益端，研发费用加计扣除对收益规模与强度同样有显著的促进作用。本文的发现肯定了我国研发费用加计扣除政策的引导作用，以及其在企业创新能力提升中发挥的积极作用。本文的研究思路为揭示政府创新激励政策的效果提供了新视角，研究发现为从创新链与企业创新能力的角度思考和改善政府研发税收优惠政策的管理和实施提供了新证据。  相似文献   

Children's drawings in different cultures: an analysis of five-year-old Jordanian children's drawings     

Jamal Fathi Ahmad 《International Journal of Early Years Education》2018,26(3):249-258

Research results have shown that what a child draws is influenced by many factors, including the child’s culture and environment. The aim of this study was to analyse the drawings of five-year-old Jordanian children to determine the extent to which culture informs the content of their drawings. A total of 736 children took part in this research project (387 boys and 349 girls). Their sample drawings were categorised according to specific themes. Results revealed that children drew pictures related to nature, people, surroundings, letters, numbers, symbols, animals, and transportation. The most frequent content of the drawings related to nature (38.9%) and the least frequent were drawings depicting violence (0.32%). Drawings also showed English and Arabic numbers and mathematical shapes separately and combined on the paper. Implications and recommendations for further research are presented.  相似文献   

Fractional order sliding mode control of a pneumatic position servo system     

Hai-Peng Ren  Xuan Wang  Jun-Tao Fan  Okyay Kaynak 《Journal of The Franklin Institute》2019,356(12):6160-6174

Gas flow has fractional order dynamics; therefore, it is reasonable to assume that the pneumatic systems with a proportional valve to regulate gas flow have fractional order dynamics as well. There is a hypothesis that the fractional order control has better control performance for this inherent fractional order system, although the model used for fractional controller design is integer order. To test this hypothesis, a fractional order sliding mode controller is proposed to control the pneumatic position servo system, which is based on the exponential reaching law. In this method, the fractional order derivative is introduced into the sliding mode surface. The stability of the controller is proven using Lyapunov theorem. Since the pressure sensor is not required, the control system configuration is simple and inexpensive. The experimental results presented indicate the proposed method has better control performance than the fractional order proportional integral derivative (FPID) controller and some conventional integral order control methods. Points to be noticed here are that the fractional order sliding mode control is superior to the integral order sliding mode counterpart, and the FPID is superior to the corresponding integral order PID, both with optimal parameters. Among all the methods compared, the proposed method achieves the highest tracking accuracy. Moreover, the proposed controller has less chattering in the manipulated variable, the energy consumption of the controller is therefore substantially reduced.  相似文献
