论高校体育教育专业体操教学探究性学习模式的构建

改变传统的教育观念和课堂教学模式,在高校体育教育专业体操教学中采取"探究性学习模式",提高学生参与学习、体验学习的程度,切实落实课堂教学学生主体性这一现代教学基本理念。本文从理论的角度介绍探究性学习及其特点,找到探究性学习模式与高校体育教育专业体操教学的多元关系,构建高校体育教育专业体操教学探究性学习的教学模式,有效提高体操教学的质量和体操教学过程中学生的学习积极性和主动性。     

安徽省农村体育的现状与对策(二)

通过对安徽省农村体育的组织管理网络层次及其工作强度、场地、设施性质及其配布、农村体育主体主要活动形式及其倾向、体育消费及其特点以及有关影响的因素等现状进行了如实反映及分析。结果表明,安徽省农村体育符合社会发展规律和节奏,但部分指标滞后、措施强度不够同时也制约着总体发展。基于现实情况,提出了改进安徽省农村体育工作的相关建议。     

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.     

论“训练感觉”

运动训练是科学与艺术的统一,训练感觉,特别是教练员、运动员直觉判断在运动训练中具有重要的意义：由于目前对训练感觉的研究很少,造成对训练感觉的认识的模糊与误区,更影响训练感觉的应有作用与有效养成。本文采用文献资料、辩证思维等方法,分析了训练感觉的意义、类别和形成。     

如何初步培养学生自主、合作的学习习惯

培养学生自主、合作的学习习惯，是顺应新课改的需要。首先，应丛培养学生良好的预习习惯做起，其次，应尽量激发学生课堂学习的兴趣，让学生自由发展。另外，还应着重培养学生课外自主、合作的学习习惯。若做到以上这些，学生势必学得主动、学得快乐，课堂教学也才能焕发出生命的活力。     

宪政视野中的人肉搜索及其规制——以死亡博客为例

人肉搜索对现实的影响有目共睹,赞叹与质疑之声从未消弥。国家已从地方层面开始试水对其规制,然而却因理论上研究不足使其饱受诟责,并在法律与舆论的边缘徘徊。以死亡博客为例,从宪政视野来分析人肉搜索的实质,可从理论上和实践上提出具体的规制。     

干涉条纹计数电路设计及应用

设计了一种基于单片机的迈克耳孙干涉条纹计数电路,该电路具有清零和选择明、暗条纹计数的功能,能对"冒出"或"缩进"的干涉条纹进行自动计数,结构简单、操作灵活、成本低,应用于迈克耳孙干涉仪测波长实验,测量波长误差在3%以内。     

政府采购制度下地方高校仪器设备采购的问题及对策

政府采购制度为地方高校在提高经费使用效益、预防腐败等方面起到了积极的作用,但政府招标采购也存在采购周期长、价格偏高、中标的仪器设备质量差等问题.根据地方高校所需求的仪器设备特点,分析地方高校实施政府招标采购存在问题的原因,提出改进高校政府采购工作的建议,以便改善地方高校实验室的装备条件.
