专家型体育教师的培养   总被引：4，自引：0，他引：4  

丁俊武  孙继龙 《军事体育进修学院学报》2003,22(1):97-99,123

国外，对专家型教师的研究已成为教育学界和心理学界的重点研究领域。国内，对此问题也相当重视，正在积极开展研究。在体育教学领域，开展有关专家型体育教师的研究，不仅对体育师资的培养和体育教师的进修培训具有现实的指导价值，而且对培养各级各类体育人才，加速我国体育事业的现代化进程也有着重要意义。借鉴心理学对专家型教师的研究成果，教学观摩、微型教学、教学决策训练、教学反思及教学研究是培养专家型体育教师的几条有效的措施和途径。  相似文献

张明霞  刘保义 《天水师范学院学报》2003,23(5):71-72

菲涅耳波带片可使入射光会聚起来，产生极大的光强，使点光源形成一系列的实像点和虚像点，其作用如同透镜成像。利用半波带分析法可分析菲涅耳波带片对称轴上的点光源通过菲涅耳波带片成像时像点在对称轴上的分布及 焦距的变化情况。  相似文献   

Medieval and renaissance glass technology in Valdelsa (Florence). Part 1: raw materials, sands and non-vitreous finds

A significant number of archaeological finds of the 13th–16th century from the Tuscan sites of Germagnana and Gambassi in Valdelsa—FI, was studied by different physico-chemical investigations (SEM–EDS, ICP, Mössbauer spectroscopy, XRD, XRF, TG-DTA) in order to contribute to clarify the production methodology and the pre-industrial glass manufacture technology. The studied samples are mainly non-vitreous finds as production waste, refractory materials, crucibles and raw materials; also vitreous finds as frits, skims, glasses (glass masses, glass working waste and finished products) have been taken into consideration. The obtained petrographic and physico-chemical data strongly suggest that both Gambassi and Germagnana glass manufactures were strictly connected with the sources of vitrifiable materials, situated in Tuscan sand quarries. In particular a comparison between sands from the neighbouring quarries and appropriate finds of the two archaeological sites evidences that the employed vitrifiable materials possibly belong to La Casina La Cava resort. The archaeological classification, based on macroscopic observation and stratigraphic position, was compared and verified with the scientific classification of the examined finds of Germagnana and Gambassi sites based on their composition, morphology and physico-chemical properties.  相似文献   

Using the Information Structure Model to Compare Profile-Based Information Filtering Systems     

Yuval Elovici  Bracha Shapira  Paul B. Kantor 《Information Retrieval》2003,6(1):75-97

In the IR field it is clear that the value of a system depends on the cost and benefit profiles of its users. It would seem obvious that different users would prefer different systems. In the TREC-9 filtering track, systems are evaluated by a utility measure specifying a given cost and benefit. However, in the study of decision systems it is known that, in some cases, one system may be unconditionally better than another. In this paper we employ a decision theoretic approach to find conditions under which an Information Filtering (IF) system is unconditionally superior to another for all users regardless of their cost and benefit profiles.It is well known that if two IF systems have equal precision the system with better recall will be preferred by all users. Similarly, with equal recall, better precision is universally preferred. We confirm these known results and discover an unexpected dominance relation in which a system with lower recall will be universally preferred provided its precision is sufficiently higher.  相似文献

跳远助跑速度变化对起跳效果的影响——国内外优秀运动员与我院选手的比较分析   总被引：1，自引：0，他引：1  

程万才 《西安体育学院学报》2003,20(2):78-79

笔者采用高速摄影、影片解析、数理统计等方法对西安体育学院男子跳远运动员和国内外优秀选手助跑速度变化而影响起跳效果的因素进行比较研究。结果表明:跳远助跑各段落速度的变化对起跳效果及成绩产生很大影响;西安体育学院男子跳远运动员绝对速度低,起跳前两步速度、速度利用率呈下降趋势,影响起跳初速度;跳远起跳前一步的速度、速度利用率对提高起跳效果要比起跳前9—10m段的速度、速度利用率更具有实际意义。  相似文献
