新时期高校如何加强民族理论政策的教育

我国是一个多民族国家,民族问题向来是党和政府关注的重点。基于此,文章着眼于高校民族理论政策教育,从多个方面来就新时期高校民族理论政策教育的进一步强化提出基本思路,意在为高校民族理论政策教育的现实开展提供借鉴与支持。     

How situational interest affects individual interest in a STEAM competition

ABSTRACT

Interest in educational research can be categorised into situational interest (SI) and individual interest (II); the sequential phases of interest development for learning have long been recognised as triggered SI, maintained SI, emerging II, and well-developed II. This study proposes an interest development model which involves SI and II mentally developed during students’ preparation for and participation in annual ‘PowerTech’ STEAM contests in Taiwan. In July 2015, data were first collected to examine students’ triggered SI, and 4 months later in the world contest to examine the local contest winning students’ maintained SI. Also, during the contest, data were collected on-site to examine the students’ emerging II. Finally, the same measurement tool was administered again for the world contest winning students 2 months later in February 2016. The results of this study showed that triggered SI is positively related to maintained SI. Maintained SI is positively related to emerging II, but it is not significantly related to well-developed II. Emerging II is positively related to well-developed II. The implication of this finding is that a well-designed competition may raise students’ SI so that emerging II and well-developed II could mature due to the effect of maintained SI.     

对网球比赛中“鹰眼”技术运用的探讨

对“鹰眼”这项科学技术是否应该被应用到网球比赛之中,并且如何合理运用进行分析探讨。通过查阅文献资料和对2006年中国网球公开赛男、女前八名选手在比赛中运用“鹰眼”技术进行数据统计,分别统计比赛场次、局数、使用次数和成功次数得出成功率并与美国网球公开赛的数据进行总结,对鹰眼技术的优缺点进行比较。同时对此类技术在其他项目比赛中的应用进行对比分析提出建议。最后得出结论：网球比赛中应使用“鹰眼”这项科学技术,并且得到合理的应用。     

试析网球教学中对学生控球能力的培养

针对学校体育网球课教学中存在的实际问题进行分析,提出应当加强对学生控球能力的培养,并对培养控球能力的定义、意义、方法作以阐述。说明网球教学中加强学生控球能力的培养,有利于掌握网球技术,使其对网球运动产生浓厚的兴趣,激发学习的动力,树立终身体育锻炼观念。     

影视传播在远距离教学中的优势、局限性及负面效应

影视传播在远距离教学中优势明显,但也存在时序结构、表达方式、交非交互性等局限性和影响逻辑思维、造成信息负荷过重等负面效应。     

试谈学校体育与素质教育

学校体育关系着国计民生 ,是学校素质教育的重要组成部分 .学校体育要完成其承担的素质教育任务必须进行相应的改革     

7—12岁儿童动作协调能力测试结果的分析研究

在研究建立了动作协调能力的理论框架与测验体系和方法的基础上 ,针对 1499名男女儿童在 9项动作协调能力的测试成绩所反映出来的行为结果 ,从项目性质、动作特征并结合年龄特征、性别特征以及增长曲线对各类测验项目进行深入的综合分析 ,找出引起上述行为结果的原因 ,使我们对这一年龄阶段儿童动作协调能力的发展规律有一客观全面更加理智的认识     

成教生物科学教育专业人才培养规格初探

21世纪是生物的世纪。要求高校培养的人才不仅具备掌握基本理论的能力，而且具备创新理论和实践的能力。为此，首先要制定明确的培养目标，其次是确定全面提高学员综合素质的基本要求，再次是确定学员的专业知识结构和能力结构，这样可根据社会发展对人才的培养要求，努力培养具有较强创新能力的专门人才。     

The effects of forearm fatigue on baseball fastball pitching,with implications about elbow injury

This study investigated the contribution of flexor muscles to the forearm through fatigue; therefore, the differences in forearm mechanisms on the pitching motion in fastball were analysed. Fifteen baseball pitchers were included in this study. Ultrasonographical examination of participants’ ulnar nerve in the cubital tunnel with the elbow extended and at 45°, 90° and 120° of flexion was carried. A three-dimensional motion analysis system with 14 reflective markers attached on participants was used for motion data collection. The electromyography system was applied over the flexor carpi ulnaris, flexor carpi radialis and extensor carpi radialis muscles of the dominant arm. Flexor carpi ulnaris muscle activity showed a significant difference during the acceleration phase, with a peak value during fastball post-fatigue (P = 0.02). Significant differences in the distance between ulnar nerve and medial condyle on throwing arm and non-throwing arm were observed as the distance increased with the elbow movement from 0° to 120° of flexion (P = 0.01). The significant increase of the flexor carpi ulnaris muscle activity might be responsible for maintaining the stability of the wrist joint. The increased diameter might compress the ulnar nerve and cause several pathological changes. Therefore, fatigue in baseball pitchers still poses a threat to the ulnar nerve because the flexor carpi ulnaris and flexor carpi radialis all originate from the medial side of the elbow, and the swelling tendons after fatigue might be a key point.
