我国优秀少年足球守门员出击技术运用情况分析     

杨磊  张强  沈培森  董向荣 《山东体育科技》2004,26(1):11-12,21

运用现场观察和常规技术统计的方法，对目前国内优秀少年足球守门员出击技术运用情况进行统计和分析，并提出建议。研究表明，对出击时机的把握性差和对抗中争接球技术运用质量水平低，是目前我国优秀少年足球守门员出击技术运用中存在的主要问题。守门员把握出击的时机，是与其对门前赛势的观察、判断及分析密不可分的，只有正确地分析门前的情况，才能把握住出击的时机。少年守门员出击意识、心理及技术应同步发展，切实提高出击的机变能力，应是少年守门员训练中的重点。应加强少年守门员对抗中的技术运用质量要求，努力改变比赛中守门员技术不过硬的现状。  相似文献

西晋党争与伐吴战争之关系论略     

于兆伟 《许昌学院学报》2002,21(1):37-40

太康元年 ,西晋不出三月而一举灭吴。其实当初西晋伐吴之时 ,并非是一帆风顺。伐吴的策略 ,是羊祜最先提出的 ,在他殁后 ,由张华、杜预、王氵睿等人继成其事。而贾充、荀勖和冯等人则从开始就极力反对 ,幸亏张华、杜预等人的积极努力和武帝的坚决支持 ,伐吴才得以最后成功。只是在伐吴问题上意见一致的张、杜、王三人并不能称之为一个党派 ,他们不是一贯结合在一起的贾充一党的对手。所以 ,在伐吴之后 ,他们不但并未因伐吴之功受到重用 ,反而遭到了疑忌、排挤甚至诋毁。  相似文献

乌江流域移民源远流长,绵延不断。几千年来,他们基于生存选择、政府组织、自发流动等诸多迁移原由,或成规模、或零散迁入并最终扎根定居于此,不但促进了中国西南边疆地区经济、政治和文化的发展,而且促进了各民族之间的融合,为中华民族共同心理素质的形成奠定了良好的基础。  相似文献   

Exergames ‘as a teacher’ of movement education: exploring knowing in moving when playing dance games in physical education     

Gunn Nyberg  Jane Meckbach 《Physical Education & Sport Pedagogy》2017,22(1):1-14

Background: A fundamental dimension of school physical education (PE) is arguably movement and movement activities. However, there is a lack of discussion in the context of PE regarding what can be called the capability to move in terms of coordinative abilities, body consciousness and educing bodily senses.

Purpose: This article explores and articulates what there is to know, from the mover's perspective, when knowing how to move in specific ways when playing exergames (dance games). Taking different ways of moving as expressing different ways of knowing as a point of departure, the following questions are the focus of this article: (i) How do students move when imitating movements in a dance game, and what different ways of knowing the movements can be described in the student group? (ii) What aspects of the movements are discerned simultaneously through the different ways of knowing the movements? (iii) What aspects seem critical for the students to discern and experience in order to know the movements in as complex a way as possible?

Design and analysis: The theoretical point of departure concerns an epistemological perspective on the capability to move as knowing how with no distinction between physical and mental skills, and also knowing as experiencing aspects of something to know. The data in this study comprise video recordings of students playing Nintendo Wii dance games in PE lessons in a compulsory school (for children aged between 7 and 16 years) in a small Swedish town. There were three PE lessons with four different stations, of which one was Nintendo Wii dance games (Just Dance 1 and 2). In total, the videoed material covers three 60-minute PE lessons, recorded during the autumn of 2012 and in which just over twenty students participated. In the study, we have used video observation as a data collection method. Jordan and Henderson maintain that video observation removes the gap between ‘what people say they do and what they, in fact, do’ (51). To conduct a systematic and thorough analysis of how the students experienced the avatar's movements, we looked for moments where all the students and the avatar could be simultaneously observed. Two video sequences were chosen, showing four students imitating two distinct and defined movements which constituted the basis for a phenomenographic analysis.

Conclusion: The result of the phenomenographic analysis shows different ways of knowing the movements as well as what aspects are discerned and experienced simultaneously by the students. In other words, these aspects also describe knowing in terms of discerning, discriminating and differentiating aspects of ways of moving. By examining a certain exergame's role ‘as a teacher,' we have emphasized the capability to move, from the mover's perspective, as an intrinsic educational goal of PE while highlighting the need for systematically planning movement education.  相似文献

Temporary Book Storage Using a Document Management Company     

Meredith Giffin  Kirsten Huhn  Andréa Harland 《资料收集管理》2019,44(1):46-68

Finding an appropriate temporary storage location for books and providing access to them is a significant challenge for libraries undergoing renovations. The current article describes the use of a document management company by an academic library to store 430,000 books for 8 months and provide a retrieval-on-demand service. Aspects covered include the selection of a commercial storage provider with its own retrieval service; details of the move to and from offsite storage; the integration of the service with library processes; communications and user feedback; book usage during the storage period; overall costs; and lessons learned from the experience.  相似文献
