The development of pattern recognition ability in children     

Les Sternberg  Paul Larson 《Contemporary educational psychology》1976,1(2):146-156

Pattern recognition development was studied in high and low ability preschool, kindergarten, and first-grade youngsters. Pattern recognition was assessed by the administration of 96 pattern tasks which measured the ability of a youngster to find: (a) duplicate patterns and elements to a model; (b) the opposite pattern to a model; and (c) duplicate patterns but different elements than in the model. Aside from main effects for grade level, ability level, and pattern task, a significant three-way interaction was noted. This interaction was analyzed in terms of its component simple effects. The implication of these simple interaction effects for Piagetian theory and educational practice were discussed.  相似文献   

The functional meanings of behaviors: A factor analytic study of motivational orientations in Virgin Islands students     

Marjorie W. Steinkamp  Yegin Habteyes 《Int J Intercult Relat》1985,9(2):187-203

One hundred and sixty-five high school students in the Virgin Islands were asked to rate the extent to which they associate each of 62 behaviors with their concepts of “success,” “joy,” and “satisfying expectations.” They were also asked to rate the frequency with which they performed each of the behaviors. Results indicated that Virgin Islands students associate the word “success” not with academic behaviors, but with being modern, attractive, and nurturing. Moreover, individual students are less apt to perform those behaviors which Western teachers believe lead to academic success and more apt to perform those behaviors which the sample as a whole associates with being successful. The data indicate that although many Virgin Islands students enjoy traditional island activities, they do not feel successful when they engage in them. The results of the investigation are interpreted within the context of what is known concerning achievement behaviors of middle-class American youth, and implications are drawn for the teaching of young persons from diverse cultural backgrounds who attend classes conducted in the Western mode.  相似文献   

第18届世界杯足球赛前场定位球攻守战术运用情况分析   总被引：2，自引：0，他引：2  

刘浩  赵勇  刘荑瑟 《中国体育科技》2007,43(4):98-102

通过文献资料调研、录像统计等方法对第18届世界杯足球赛前场定位球进攻和防守战术运用情况进行统计、分析,得出以下主要结论:1)随着足球比赛激烈程度的提高,前场定位球攻守战术运用效果,已成为影响比赛胜负结果的重要因素之一;2)本届世界杯足球赛任意球直接射门数少于配合射门数;3)前场任意球防守力量分布主要体现在3个部分,一是防守人墙;二是封锁要害空间;三是盯防进攻运动员。任意球罚球点区域变化,防守力量重点随之变化;4)本届世界杯足球赛角球进攻组织配合形式以长传角球为主,长传角球射门次数以及进球率高于战术角球,但战术角球的射门率比长传角球高;5)在进行角球防守组织和区域布防时,防守长传角球时一般不设置专门运动员防守罚球运动员,前、后门柱区域是防守重点之一。  相似文献   

第18届世界杯足球赛裁判员执法状况研究     

课题组 《上海体育学院学报》2007,31(6):36-43

采用文献资料法、专家访谈法、数理统计法，对第18届世界杯足球赛决赛阶段比赛中裁判员、助理裁判员、第4官员的执法状况进行研究。结果发现，与第17届世界杯赛相比，第18届世界杯赛裁判员在奔跑能力、判罚距离、掌握有利、估计损失时间、处理伤员注重“人性化”等方面均有一定进步，但是判罚犯规和越位的准确性有所下降；判罚球点球的准确率仍维持在54％水平上，但漏判增多；使用红黄牌准确性大体相仿，但出现了使用不当和低级错误的个案。其原因与第18届世界杯赛裁判员选派办法不当、赛前片面注重体能准备、仓促使用耳麦、赛中取消裁判员集体总结有关。  相似文献   

18届世界杯足球赛进球情况统计分析     

管勇 《南京体育学院学报(社会科学版)》2007,21(2):57-59,30

通过对18届世界杯足球赛全部64场比赛的147个进球情况,进行统计分析,结果显示:球门正面2、3区域进球最多,是防守的重中之重,6、7区是远射的最佳区域;比赛的最后15分钟是进球的高峰期,防守时应集中注意力;直接抢点射门进球最多,前锋队员是进球的主力;中路进攻入球最多,突出中路进攻、加强边路进攻是趋势;通过定位球战术进球53个,比例在上升,已成为球队进攻的重要手段。  相似文献

Contests for cooperation—A new approach in German innovation policy     

Alexander Eickelpasch  Michael Fritsch 《Research Policy》2005,34(8):1269-1282

A new approach in German innovation policy organizes contests of proposals for developing innovation networks. Based on an overview of the different programs, we investigate the advantages and problems of such an approach. We find that this type of policy may have a relatively large impact and can, therefore, be regarded as a rather efficient instrument of innovation policy. Compared to conventional policies, administration of the program is a much more critical issue. The contest approach may stimulate learning effects on the side of the administration but may also require a high degree of flexibility. The main disadvantage is the additional time that is required for conducting the contest. As a distinct ‘picking the winner’ approach, the contest approach is not suited as a means for achieving a leveling-out of regional welfare.  相似文献
