通过对参加第 14届世界女排锦标赛中国女排与意大利、巴西 (二场 )、韩国、澳大利亚、希腊五队六场比赛得分情况的比较分析 ,以及中国队和本届冠军意大利队两队比赛得分情况的单独比较分析 ,发现各队得分多少依次是一攻、对失、防反、拦网、发球 ,主要得分环节一攻得分数中国队多于其它五队平均数 ,也多于意大利队 ,一攻得分占本队得分比例 ,中国队稍低于其它五队平均值 ,高于意大利队。中国队在整个比赛中失误过多 ,而过多的失误又是导致比赛失利的主要原因之一  相似文献   

A Critical Look into the Beuk Standard-Setting Method     

Adam E. Wyse 《Educational Measurement》2020,39(1):52-60

One commonly used compromise standard-setting method is the Beuk (1984) method. A key assumption of the Beuk method is that the emphasis given to the pass rate and the percent correct ratings should be proportional to the extent that the panelists agree on their ratings. However, whether the slope of Beuk line reflects the emphasis that panelists believe should be assigned to the pass rate and the percentage correct ratings has not be fully tested. In this article, I evaluate this critical assumption of the Beuk method by asking panelists to assign importance weights to their percentage correct and pass rate judgments. I show that in several cases that the emphasis suggested by the Beuk slope is noticeably different from what one would expect and is inconsistent with importance weight ratings. I also suggest two ways that the importance weights can be used to calculate alternate cut scores, and I show that one of the ways of calculating cut scores using the importance weights leads to larger potential differences in cut score estimates. I suggest that practitioners should consider collecting importance weights when the Beuk method is used for determining cut scores.  相似文献   

Adolescents earlier diagnosed as dyslexic show major IQ declines on the WISC-III     

P. T. Ackerman  N. L. Weir  C. A. Holloway  R. A. Dykman 《Reading and writing》1995,7(2):163-170

Adolescents (n=43) previously diagnosed as dyslexic/reading disabled had markedly lower IQ scores on the newly standardized Wechsler Intelligence Scale for Children (WISC-III) than on the earlier administered WISC-R. The declines for Verbal, Performance, and Full Scale IQs were 10, 12, and 11 points, respectively, which were twice as great as in a subset of the standardization sample given both versions of the WISC. The adolescents did not show a significant decline in standard scores from the Wide Range Achievement Test (Level I to Level II). However, only two subjects had current reading and spelling standard scores above the 25th percentile. The impact of lower WISC-III IQs on guidelines for classification of students as learning disabled is discussed.  相似文献   

学前教育对青少年成就发展的影响——基于CEPS数据的实证研究     

方超  黄斌 《教育学报》2020,(1):73-82

基于中国人民大学提供的中国教育追踪调查数据,采用倾向得分匹配法,实证检验学前教育经历对青少年成就发展的现实影响,讨论“去小学”化的现实必要性。结果发现:接受学前教育和未接受学前教育的青少年在学业表现、家庭特征与个体特征等方面存在着一定的差异;Logit模型发现了家庭人力资本存量、经济资本以及家庭规模均对学前教育参与率的提升起到积极影响,但农村青少年的学前教育参与率相对于城镇要低2.3个百分点,显示出学前教育资源在城乡间的非均衡分布;倾向得分匹配法揭示了学前教育经历对青少年的学业表现具有正向影响,尤其是对语文和数学成绩的促进作用最为明显,但提前接触小学教育内容并不能帮助青少年赢在起跑线上。  相似文献

颈动脉内膜中层厚度与心血管危险因素聚集性的关系   总被引：8，自引：0，他引：8  

王义成  袁桂莉  赵久安 《河北北方学院学报(医学版)》2005,22(4):33-37

目的:通过对颈动脉IMT(颈动脉内中膜厚度intima-media thickness)和粥样斑块进行超声检测,分析心血管危险因素聚集性与颈动脉粥样硬化的关系.方法:227例受检者,男139例,女88例,年龄45～57岁(平均53.25±3.01岁).大部分受检者有多重危险因素但临床上无严重动脉粥样硬化疾病并以药物治疗为主.1.记录身高、体重、腰围及血压、空腹血糖、血脂,吸烟史及家族史.2.颈动脉彩色多普勒超声检查:分别测量颈总动脉、颈动脉膨大处,颈内动脉取平均IMT.3.根据颈动脉超声结果分组,正常对照组,IMT增厚组,斑块形成组.4.冠心病危险因素按国际标准确定:危险因素评分范围为0～5,以危险因素评分≥2定义为危险因素聚集.结果:1.各组间心血管危险因素水平的比较 :三组有统计学意义(P＜0.05).并且随血压、血糖、胆固醇、腰围水平升高,随LDL-L下降,颈动脉(IMT)加重.2.各组间心血管危险因素异常检出率比较:高血压、高血糖、高胆固醇血症、高LDL-C血症组间比较有统计学意义(P＜0.05),随颈动脉IMT加重,高血压、高血糖、高胆固醇血症、高LDL-C血症异常检出率明显升高.3.各组心血管危险因素积分比较:根据心血管危险因素积分按等级检验进行秩和检验(H=20.16,P＜0.05),并且随IMT增厚,危险因素积分逐渐升高.4.颈动脉IMT与心血管危险因素的相关分析:在双变量Spearsman相关分析中,颈动脉内中膜厚度与各危险因素及危险因素评分呈显著相关(P＜0.05),在调整性别、年龄进行偏相关分析中,IMT与舒张压、HDL-C的相关性无统计学意义(P＞0.05),与FBG、SBP、TC、TG、LDL-C、RFS存在显著相关性(P＜0.01).IMT与危险因素评分的相关系数分别为0.407与0.219.结论:心血管危险因素的聚集,提示颈动脉粥样硬化程度严重,预示颈动脉粥样硬化病变与多种心血管危险因素的聚集有显著相关性.  相似文献

NCME 2007 Presidential Address: The Concordance Table: An Invitation to Misuse Test Scores     

Daniel R. Eignor 《Educational Measurement》2008,27(4):30-33

This article discusses a particular type of concordance table and the potential for test score misuse that may result from employing such a table. The concordance that is discussed is typically created between scores on different, nonequatable versions of a test that share the same or close to the same test title. These concordance tables often appear in the context of relating scores on computerized adaptive and paper‐and‐pencil versions of the same test. When such a table is presented in a complete point‐by‐point fashion, relating each reported score on the scale of the new version of the test to a reported score on the scale of the old version of the test, test score users will typically treat the table as if it represented an equating of scores between the two versions, and directly replace scores on the new version of the test by scores on the old version. This clearly represents a misuse of the test scores. Suggestions for avoiding this misuse of test scores from concordance tables are provided.  相似文献
