在体育教学中运用自我效能动机理论的思考

自我效能理论,是动机学习理论体系中的一种有代表性的理论.体育教学是一种技术教学,非智力因素在体育教学中占有十分重要的地位,因而强调学习动机对体育教学有特殊的意义.在当前的体育教学改革实践中,要充分重视学生在学习活动中形成和提高自我效能感,发挥学生的主观能动性.     

培养和激发自我效能感与体操教学

采用文献资料法、问卷调查法、实验对比法和数理统计法,运用自我效能感的原理,在高师体育教育专业体操教学中进行培养和激发学生及教师自我效能感的实验研究.结果表明,实验班成绩优于对照班,且有非常显著性的差异;在体操教学中培养和激发学生及教师的自我效能感,可以有效地提高体操教学的效果和学生的成绩.     

不同负荷下武术运动员部分感受性变化的研究

采用训练现场监测方式，测试武术运动员在不同负荷下反应时、肌肉用力感、操作思维及肘关节动觉准确性4项指标的变化，结果表明：随负荷加大，反应时下降；其余几项指标在次大负荷时有所提高，而在大负荷时又呈现下降趋势，且感受性的变化具有不均衡性的特点。     

我看语感训练

语文是一门综合的实践课，学好语文，用好语文知识，对一个人终身受用。而学好语文的精微妙处就是对语言文字的理解、感受能力即语感。作为一名语文教师，应致力于从口头表达和文字书写两方面去训练学生的“语感”。口语训练要做到“言为心声，心口合一”；书面训练要做到“文以载道，妙笔生辉”。     

高校素质教育与大学生终身健身意识的培养

通过对素质教育的涵义、终身健身意识的涵义、学校体育与素质教育的关系论述了素质教育在高校体育教育中的地位，分析了高校大学生体育锻炼的现状和存在的问题，探讨了实施素质教育与大学生终身健身意识培养的途径、方法和重要性。     

明确“六个意识” 建设科技期刊强国

建设科技期刊强国是提升我国科技话语权和文化软实力、适应创新型国家发展需要、支撑科技强国和文化强国建设的重要举措。意识是行为的先导,面对动荡、变革、竞争的世界格局,必须首先统一我国期刊人的意识观念,才能保证科技期刊强国建设的中国特色和正确方向。我国建设科技期刊强国的整体性、复杂性、国际性、协同性、艰巨性等特点,要求期刊人必须具备敏锐的政治意识、警觉的风险意识、自信的平视意识、勇毅的担当意识、坚定的初心意识和不辍的创新意识,走出一条中国特色科技期刊发展道路,为建设世界科技强国、实现中华民族伟大复兴的中国梦作出更大贡献。     

让学生生惑、解惑的数学教学设计

数学教学不仅要重结论,更要重过程。"惑"作为教学的出发点,不直接展示结论,而是通过恰当地设置问题情境,提出带有启发性和挑战性的问题——让学生生惑,为学生提供动手、动脑的机会,引导学生运用观察、分析、综合、归纳、抽象概括、类比、猜想等方法去研究、去探索、去解惑,充分地让学生学会"数学地思考"。     

浅谈儿童期技术表象训练对游泳技术的影响

本文采用随机编组对照实验的方法,分析儿童期游泳运动员技术表象训练对游泳技术的影响,并对“表象”训练在训练中的作用以及如何培养和发展良好的“水感”进行了探讨．研究表明,运用正确的“表象”训练,使运动员合理掌握技术动作,养成良好的技术风格,对提高“水感”和运动成绩,都有着十分重要的意义。     

Spatial Discovery of Linked Research Datasets and Documents at a Spatially Enabled Research Library

Current publishing practices in academia tend to result in datasets that are difficult to discover. This is because datasets are not well-integrated across academic domains and they are often not linked to the documents that reference them. For these reasons, discovering datasets across domains can be challenging; for example, discovering archeological observations and biological specimens using the same search is not widely supported, even if both datasets share a similar spatial extent, like Mesoamerica. It is also challenging to retrieve relevant documents that reference datasets; for example, retrieving a series of field reports that reference archeological observations is typically not supported. Our work develops an extensible method for: (1) geographically integrating collections across disciplinary repositories and (2) connecting datasets to related documents. We describe a collection of spatially-referenced researcher datasets, capturing their metadata elements and encoding them as linked open data. We then leverage existing library services to formalize links from datasets to documents. The system described in this work has been deployed, resulting in an experimental open data site for the UCSB campus. Results indicate that this system can be scaled-up with support from an institutional repository in the near future.     

Photonic orbital angular momentum with controllable orientation

Vortices are whirling disturbances, commonly found in nature, ranging from tremendously small scales in Bose-Einstein condensations to cosmologically colossal scales in spiral galaxies. An optical vortex, generally associated with a spiral phase, can carry orbital angular momentum (OAM). The optical OAM can either be in the longitudinal direction if the spiral phase twists in the spatial domain or in the transverse direction if the phase rotates in the spatiotemporal domain. In this article, we demonstrate the intersection of spatiotemporal vortices and spatial vortices in a wave packet. As a result of this intersection, the wave packet hosts a tilted OAM that provides an additional degree of freedom to the applications that harness the OAM of photons.
