ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献   

An exploration of young professional football players’ perceptions of the talent development process in England     

《Sport Management Review》2020,23(3):536-547

The identification and development of players in English professional football has become an increasingly significant topic of debate given the historical perceived underperformance of the English national team at international tournaments. To enhance understanding of the challenges and barriers experienced by English youth footballers, the authors explore the developmental experiences of English professional football players from different levels of the English football pyramid. Professional players (N = 11) from football clubs in the top four professional divisions in England took part in individual semi-structured interviews, which were analysed inductively using thematic analysis. The data revealed three interrelated themes that were perceived to mediate player identification and development pathways at professional clubs. Pathways for young players to progress and experience first-team competitive football differed when the level of the league that the players operated within was considered, with significant issues also raised relating to the suitability of the under 21 league structure, the importance attached to the educational welfare of young players, and variations in the identification of player attributes. This study sheds new light on the priorities and processes of talent development and education provision in English football.  相似文献

按规则同指的关联主义语义解释     

邵世恒 《科学技术哲学研究》2021,38(1):46-51

自然语言中存在着一类特殊的同指事实——按规则同指,语言胜任主体仅凭语言能力就可以知道这类事实。基于语义要求概念,关联主义语义学为这类事实提供了语义解释策略。该策略的成功依赖于语义必然性论证的成立,这一论证以语义要求为中项勾连起语言理解和语义知识,已有的反驳针对该论证的两个前提之一。然而,该策略真正的问题在于,语义必然性论证并不能建立起语义要求作为解释项的唯一性,语义要求的唯一性只建立在它的特设性上。  相似文献   

基于UML的自动排课系统的需求分析   总被引：4，自引：0，他引：4  

杨威  喻国平 《科技广场》2005,(2):61-63

UML是建立系统模型和分析业务处理流程的强有力的可视化建模工具。文中探讨了基于UML的系统需求分析的方法，并用此方法对《基于并行处理机调度算法思想的高校智能排课系统》进行了需求分析。实践表明：与传统的以文字说明方式的需求分析方法相比，用UML进行需求分析具有良好的优越性。  相似文献   

贝尔纳科学社会学思想再认识   总被引：2，自引：0，他引：2

认为贝尔纳科学社会学最突出的理论贡献有二:(1)力主科学的可计划性,并系统阐述了计划科学的理论基础和实施对策等;(2)对科学的社会功能问题进行了深入研究。指出在上述两个方面,贝尔纳的科学社会学也存在明显缺陷,而且对马克思主义哲学有某些误读,其中,对经济需要与科学发展关系上的机械理解即是典型的一例。  相似文献

泾河流域水资源需求结构分析与调控策略   总被引：1，自引：0，他引：1

泾河流域生态环境脆弱，水土流失严重，同时水资源短缺这些都已成为其发展的障碍，因此有必要弄清流域目前水资源需求状况和存在的问题。水资源需求部门主要是农业需水、工业需水、城镇居民生活需水、农村居民生活需水、河流生态环境需水、林地需水和草地需水，分别属于生产需水、生活需水和生态环境需水。为表征不同部门需水的时空特征，计算了该区域2000年各县各类需水部门的需水量，并从水资源需求部门差异、空间差异和时间匹配三个方面进行分析。结果表明：①各县总需水量变化在1.57×10⁸m³～14×10⁸m³之间，流域单位面积需水量变化在145.11mm～728.98mm之间，基本趋势是由东南向西北逐渐减少; ②流域以生产需水和生态需水为主，生产需水以农作物需水为主，在2/3县区易出现生产与生态环境争水现象; ③农作物和林地，尤其是农作物亏缺水量大，目前的灌溉水平很难改变亏缺局面，势必影响二者经济效益和生态效益的发挥; ④农业结构性用水短缺格局相对突出。单位面积农作物需水量，最高值在泾阳县，为5 682 m³/hm²；最低值在定边县，为4 022 m³/hm²，由于事先设定大多数需水定额不随县(区)的改变而改变，因此该值与作物结构密切相关。本文根据上述研究结果，对该区域水资源的合理利用提出建议，要求重点加强植被结构与农作物结构的调整。  相似文献
