在升学与就业的双重压力下,无论学校、教师还是大学生本人都对普通高校体育课程存在不同程度的忽视心理与忽视行为。从体育课程的教学形式、教学内容、教学时长来看,并没有起到促进大学生综合素质提升的作用,也没有对高等教育体系完善做出应有的贡献。而在教学过程中,大学生的个人意愿、学习的主观能动性也没有得到挖掘与激发。可以说,大学体育课程缺乏以人为本的教学理念。这些问题成为大学体育课程亟待改革的弊端。  相似文献

目的:探讨我国优秀花样游泳运动员功能性动作能力与力量素质的相关性,分析功能动作筛查测试与力量素质测试结果存在的内在联系,从专项视角探讨花样游泳运动项目的训练策略并提出建议。方法:选取国家花样游泳队14名健将级运动员为研究对象,对其进行FMS、握力、上肢力量、股内收肌群力量、躯干核心耐力、下肢爆发力测试,并对测试结果进行相关性分析。结果:1)14名花样游泳运动员FMS测试平均得分为15.21分,有5人测试得分低于运动损伤高风险的临界值(14分);2)FMS测试总分与Keiser坐姿上推(偏相关系数=0.622,P<0.05)、45°股内收肌群横向收缩力量(偏相关系数=0.652,P<0.05)、90°股内收肌群横向收缩力量(偏相关系数=0.746,P<0.01)均呈正相关;3)直线弓步蹲与Keiser坐姿上推(偏相关系数=0.711,P<0.05)、无反向纵跳(偏相关系数=0.661,P<0.05)、有反向纵跳(偏相关系数=0.614,P<0.05)和40 cm跳深跳高(偏相关系数=0.754,P<0.01)均呈正相关;肩部灵活性测试得分与Keiser下蹲上推(偏相关系数=0.575,P<0.05)、45°股内收肌群横向收缩力量(偏相关系数=0.585,P<0.05)以及90°股内收肌群横向收缩力量(r=0.867,P<0.01)均呈正相关,与仰桥耐力呈负相关(偏相关系数=0.701,P<0.05);旋转稳定性与40 cm跳深跳高呈正相关(偏相关系数=0.575,P<0.05)。结论:我国优秀花样游泳运动员髋关节主动灵活性和臀大肌-髂胫束联合等肌群的主动柔韧性较好,但存在膝关节、髋关节稳定性差、躯干核心区肌群控制力不足等问题,受主导臂和主导腿均为右侧影响,运动员身体两侧不平衡明显。运动员FMS测试得分并不能全面反映其力量素质的高低,FMS测试得分与部分力量素质测试结果存在相关性,可能与两种测试均涉及同一动力链结构系统肌群的协同工作和动作存在做功类型的相似性有关。  相似文献

ABSTRACT

This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players.  相似文献

Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.  相似文献

Misconceptions about adaptation by natural selection are widespread among adults and likely stem, in part, from cognitive biases and intuitive theories observable in early childhood. Current educational guidelines that recommend delaying comprehensive instruction on the topic of adaptation until adolescence, therefore, raise concerns because children's scientifically inaccurate theories about species may be left unchallenged for many years, allowing them to entrench and become difficult to overcome. In consequence, this investigation sought to explore whether classrooms of kindergartners and second graders could acquire a basic but comprehensive understanding of adaptation from an intervention constructed around two picture storybooks that mechanistically explain natural selection. Learning was assessed in near and far transfer contexts both immediately and a month later. Kindergartners and second graders demonstrated substantial learning of biological information; however, second graders showed pronounced abilities to near and far generalize, immediately and over time. Results suggest that causally cohesive interventions with an emphasis on mechanistic explanation facilitate children's classroom learning of complex counterintuitive scientific ideas.  相似文献

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

This paper will offer some insights into possible ways to optimise the blended learning environment based on experience with this modality of teaching at Arab Open University/Jordan branch and also by reflecting upon the results of several meta-analytical studies, which have shown blended learning environments to be more effective than their face to face and online only counterparts. Three key elements will be presented as important ways for improving the blended learning environment: forging genuine collaborative partnerships between institutions in terms of the team-writing of Open and Distance Learning (ODL) material, adopting a more theoretically based instructional approach, such as the cognitive apprenticeship (CA) model, which emphasises making thinking visible and developing a comprehensive understanding of blended education in order to help students achieve their educational goals.  相似文献
