Background: Physical Education (PE) has been associated with a multi-activity model in which movement is related to sport discourses and sport techniques. However, as in many international contexts, the Swedish national PE syllabus calls for a wider and more inclusive concept of movement. Complex movement adapted to different settings is valued, and in the national grading criteria qualitative measures of movement are used. This research seeks to examine how the wider concept of movement is interpreted and graded. Drawing on Bernstein’s concept of the pedagogic device, the paper explores teachers’ roles as active mediators in the transformation of national grading criteria for movement and the kinds of movement that are valued in teachers’ grading practices. Purpose: The purpose of this study is to investigate what PE teachers consider legitimate movement in a criterion-referenced grading system and the factors that influence their grading practice. The Repertory Grid (RG) technique was employed in order to access their tacit knowledge. Methodology: Seven Swedish PE teachers were interviewed, all of whom teach and grade years seven to nine in different compulsory schools. Using the RG technique, the teachers were asked to reflect on the aspects they considered important for achieving a high grade. The national grading criteria for years seven to nine were then presented one at a time and the teachers were asked to describe how they assessed and graded each requirement. The teachers were also asked whether any specific factors had influenced their grading. In the content analysis, the second part of the interview was attended to first and the results were interpreted in light of Bernsteins’ concept of the pedagogic device. Findings: Sport techniques and competitive sports influenced the teachers’ interpretations of what constitutes complex movement. The aspect of fitness also appeared to be valued by the teachers in that it facilitates the valued movement. In some cases the difficulty of describing movement qualities in words could reduce the concept of movement to something measurable and quantifiable. The teachers’ concerns about students’ unequal opportunities to develop and demonstrate their skills also influenced the teachers’ interpretation of complex movement. Conclusions: In the transformation of national grading criteria to grading practice, the pedagogic actions taken inform and limit the way in which legitimate movement in PE is conceptualised. Adopting a concept of movement that is wider than competitive sports allows the structures of inequality to be addressed and enables the movements performed by students with other moving experiences than competitive sports to be valued. The tension between the demands of transparency in a high stakes grading system and the inability to articulate the quality of complex movements is problematic. There is a need to verbalise teachers’ conceptions about physical education knowledge to be able to discuss and develop the concept of movement. In this process, the RG technique is a potentially useful tool. Having the language to discuss movement qualities also enables us to strengthen the interrelation between curriculum, pedagogy and assessment.  相似文献

土地革命时期的少年先锋队是一个革命青年的半武装组织。在中国共产党、共青团和苏维埃政府的关心下,少年先锋队领导苏区青年为争取自身阶级利益,保卫苏维埃政权,努力学习知识,并积极投身于革命运动中。他们参与阶级斗争,帮助政府实现各项政治经济政策;开展拥军优属活动,帮助工农群众进行生产建设;训练和培养了大批红军后备力量,帮助红军、赤卫军、游击队保卫苏区政府和人民的安全,并为前线输送了大量优秀战士。在近代中国青年运动史上,少年先锋队组织有着不可磨灭的伟大贡献。  相似文献

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.  相似文献

目的:采用功能性动作测试系统(Functional Movement Screen,FMS)评价青少年在完成不同功能动作模式时身体各部分的稳定性、对称性和灵活性,研究其基本运动能力及影响因素。方法:以上海市某中学中随机挑选的100名初中生为研究对象,对他们进行7个特定动作的测试并评分,并对测试结果进行统计分析。结果:FMS测试总分满分为21,受试对象FMS总分均分为14.89,总体水平偏低;女生肩关节灵活性和直腿抬高测试得分显著高于男生,但总分上男女生无显著差异;青少年在完成动作时普遍存在身体晃动、力量不足和两侧肌力不对称现象,髋、膝、踝关节灵活性受限且稳定性较差,脊柱的屈伸能力不足,两侧盂肱关节和髋关节的活动能力不对称。在旋转稳定性、跨栏架和直线弓箭步3个测试中这些不足尤为明显。结论:青少年基本运动能力水平较低,大多数人需要进行矫正训练;男女生总体上的表现差异不显著,但女生在肩部灵活性和直腿抬高测试的表现要优于男生,故男生需加强肩部和髋部关节的灵活性锻炼。  相似文献

In lateral reactive movements, core stability may influence knee and hip joint kinematics and kinetics. Insufficient core stabilisation is discussed as a major risk factor for anterior cruciate ligament (ACL) injuries. Due to the higher probability of ACL injuries in women, this study concentrates on how gender influences trunk, pelvis and leg kinematics during lateral reactive jumps (LRJs). Perturbations were investigated in 12 men and 12 women performing LRJs under three different landing conditions: a movable landing platform was programmed to slide, resist or counteract upon landing. Potential group effects on three-dimensional trunk, pelvic, hip and knee kinematics were analysed for initial contact (IC) and the time of peak pelvic medial tilt (PPT). Regardless of landing conditions, the joint excursions in the entire lower limb joints were gender-specific. Women exhibited higher trunk left axial rotation at PPT (women: 4.0 ± 7.5°, men: ?3.1 ± 8.2°; p = 0.011) and higher hip external rotation at both IC and PPT (p < 0.01). But women demonstrated higher knee abduction compared to men. Men demonstrated more medial pelvic tilt at IC and especially PPT (men: –5.8 ± 4.9°, women: 0.3 ± 6.3°; p = 0.015). Strategies for maintaining trunk, pelvis and lower limb alignment during lateral reactive movements were gender-specific; the trunk and hip rotations displayed by the women were associated with the higher knee abduction amplitudes and therefore might reflect a movement strategy which is associated with higher injury risk. However, training interventions are needed to fully understand how gender-specific core stability strategies are related to performance and knee injury.  相似文献

华盛顿会议前后,民众通过组织国民外交团体、联合派遣国民外交代表等形式,表达自身在外交活动中的意愿和诉求,使国民外交运动在独立自主、联合发展方面有了进一步的发展。华盛顿会议后期,民众外交上的诉求未得到满足,国民外交运动由外转内,斗争目标指向北京政府。这种转变,推动了国内政局的变化,也导致了国民外交运动的分裂。  相似文献
