"四人制"篮球教学比赛在普通高校中的推广意义   总被引：7，自引：0，他引：7  

彭敏 《体育与科学》2002,23(5):80-80,77

篮球运动作为非隔网的同场对抗的集体项目,提高学生在对抗中施展技、战术能力,是我们教学的最终目的。通过将“四人制”比赛法纳入篮球专项课的教学过程。经过实验对比表明,运动强度及基本战术的掌握和运用等方面的效果,“四人制”比赛都更优于“三人制”比赛,更适合作为篮球专项课中的教学手段之一。  相似文献   

The evidence for the impact of policy on physical activity outcomes within the school setting: A systematic review

BackgroundDespite the well-established health benefits of physical activity (PA) for young people (aged 4–19 years), most do not meet PA guidelines. Policies that support PA in schools may be promising, but their impact on PA behavior is poorly understood. The aim of this systematic review was to ascertain the level and type of evidence reported in the international scientific literature for policies within the school setting that contribute directly or indirectly to increasing PA.MethodsThis systematic review is compliant with Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Six databases were searched using key concepts of policy, school, evaluation, and PA. Following title and abstract screening of 2323 studies, 25 progressed to data synthesis. Methodological quality was assessed using standardized tools, and the strength of the evidence of policy impact was described based on pre-determined codes: positive, negative, inconclusive, or untested statistically.ResultsEvidence emerged for 9 policy areas that had a direct or indirect effect on PA within the school setting. These were whole school PA policy, physical education, sport/extracurricular PA, classroom-based PA, active breaks/recess, physical environment, shared use agreements, active school transport, and surveillance. The bulk of the evidence was significantly positive (54%), 27% was inconclusive, 9% was significantly negative, and 11% was untested (due to rounding, some numbers add to 99% or 101%). Frequency of evidence was highest in the primary setting (41%), 34% in the secondary setting, and 24% in primary/secondary combined school settings. By policy area, frequency of evidence was highest for sport/extracurricular PA (35%), 17% for physical education, and 12% for whole school PA policy, with evidence for shared use agreements between schools and local communities rarely reported (2%). Comparing relative strength of evidence, the evidence for shared use agreements, though sparse, was 100% positive, while 60% of the evidence for whole school PA policy, 59% of the evidence for sport/extracurricular PA, 57% of the evidence for physical education, 50% of the evidence for PA in classroom, and 50% of the evidence for active breaks/recess were positive.ConclusionThe current evidence base supports the effectiveness of PA policy actions within the school setting but cautions against a “one-size-fits-all” approach and emphasizes the need to examine policy implementation to maximize translation into practice. Greater clarity regarding terminology, measurement, and methods for evaluation of policy interventions is needed.  相似文献   

基于云平台的PXE技术在远程数据处理中的应用     

彭仁明  李岷 《绵阳师范学院学报》2013,32(5):15-19

在某些工程应用环境中,需要进行信息交互、数据清洗等远程数据处理工作.同时为了提高企业资源的利用率,需要具备良好扩展性、易于维护且更低成本的网络应用.本文提出了一种基于虚拟计算平台的PXE网络构建方案,与传统方法相比,该方案实现了数据中心的虚拟化,云模式的数据处理方式更具灵活性和安全性,降低了网络构造的复杂性和软硬件成本,提高了数据处理的运行效率和系统的整合能力,更容易实现管理和维护.  相似文献   

音乐审美趣味特点的社会心理观照     

邹建林  彭晓凤 《江西师范大学学报(哲学社会科学版)》2002,35(4):114-119

音乐审美趣味具有主观性、自由性、封闭性、保守性，同时又具有开放性和可转移性；音乐趣味特点的形成不是浅显的感觉和单一的情感因素构成，而是由一个庞大复杂的社会心理结构系统支配着它；不同的时代、民族、阶级和不同的群体，由于其社会条件背景的不同而构成了音乐审美趣味的差异。  相似文献   

初中物理教科书中的能量概念比较研究     

TAN Xiao PEN Zheng 《课程.教材.教法》2008,(12)

当前,在世界范围内,能量概念在科学教育尤其是物理教育中占据着越来越重要的地位。然而,能量概念的特殊性决定了能量概念教学的多样性和复杂性。关于能量概念的教学,我国的中学物理课程与国外的许多教程有较大差异。比较国内外物理教科书中关于能量概念的呈现方式和教学方式的差异,对改进能量概念在教科书中的呈现方式进而帮助学生进一步理解能量的概念具有一定意义。  相似文献
