为提高女子少儿体操运动员选材效果 ,科学地制订运动训练计划以及有效地控制训练的过程 ,对山东省连续两年获得女子 6~ 7岁组团体冠军的新泰体操运动学校 8名优秀运动员 ,进行了身体形态、素质、基本技术等因素各指标的测试 ,用因素分析法探讨了各因素对竞技能力的关联程度。结果表明 ,身体形态匀称即四肢长、手大、髋小、肩宽、体重轻等的女子少儿是较理想的体形 ;素质训练过程中 ,应着重注意增强腹背力量、爆发力和上肢力量 (尤其是支撑力量 ) ;基本技术训练过程中 ,应偏重于自由操翻腾技术的训练 ,这样对其他三项的翻腾技术起到正诱导和促进作用 ,能进一步提高竞技能力。 相似文献

As a part of efforts to evaluate and monitor the increasing public investment in early childhood education, teachers are being asked to assess children's school readiness. In this study, preschool teachers and kindergarten teachers rated children's skills in three areas (kindergarten readiness, academic skills, and communication skills), and these ratings were compared with direct assessments of the children's skills. Ratings by both groups of teachers tended to be more highly related to basic skills, such as counting and number naming, than to abilities such as solving applied problems and using expressive and receptive vocabulary. Preschool teachers' ratings had a lower association with children's observed skills and abilities than kindergarten teachers' ratings. Ratings of children attending Head Start were systematically inflated, but this relationship was mediated to a significant extent by the teachers' levels of education. More educated teachers rated children in a manner consistent with the children's directly assessed skills. Implications of these findings for informing future efforts to assess school readiness by using teacher ratings are discussed. 相似文献

Research on psychometric methods is heavily dependent on software. The quality, availability, and documentation of such software are critical to the advancement of the field. In 2000, an ad hoc committee of NCME recommended that NCME adopt policies that promote greater availability and better documentation of software. This article follows the ad hoc committee's report by examining the use of software in four top-tiered journals in recent years. The results indicated that the most frequently cited programs were those written by the articles' authors. The documentation and availability for these programs are often not clear, particularly for software used for simulations. The use of proprietary software was not widespread in the four journals, but there is still room for concern in the future. This article recommends that NCME form a permanent committee to address software issues. 相似文献

Information access is central to library and information science, yet explorations of its conceptual nature have been limited. Given the importance of information access to the discipline, there is a need for research to create a better understanding of the concept and its many roles in all activities and behaviors related to information. Drawing on the theoretical work of Elfreda Chatman, this article proposes that the study of information access can be facilitated through the recognition and examination of the physical, intellectual, and social aspects of information access. These types of access are examined through three case studies in terms of different information behaviors and contexts, with a particular focus on the importance of social access. The article also discusses the future roles that considerations of social access can play in research and theory. 相似文献

馆藏比照评估的量化指标及其应用分析 总被引:1,自引:0,他引:1
类比测量误差理论,提出文献信息资源评估体系的绝对馆藏冗余、馆藏保障率、馆藏冗余率等三个量化指标,借以指导可持续发展馆藏的评估工作。作为一个应用实践,根据Ul-rich期刊分类标准,比照分析同济大学图书馆馆藏纸本和电子英文期刊品种数量的规模、相对占有份额和可持续发展空间等以上指标的整体分布规律。结果表明,同济馆藏外文期刊品种数量的总体走向趋于一指数分布,且可以划分为明显的分类区间,基本符合学校学科设置和发展规划,在保障传统特色和基础研究领域的前提下,照顾一些新兴边缘学科的馆藏建设。 相似文献
