关于测验成绩正态分布与偏态分布的思考     

丁梦扬  蒋波 《常熟理工学院学报》2008,22(6):85-87

教育评价过程中,成绩的分布形态是由测验的目的、功能和评定标准,学生的能力素质和知识基础,教师和学生的积极能动性,学生群体规模的大小及学生的学习时间和效率等因素决定的。必须客观、全面地评价正态分布与偏态分布的利弊,在此基础上对两者加以有效整合,以提高测验的真实性和实用性,促成全体师生的共同努力,促进全体学生的共同发展。  相似文献

大学英语口语测试体系的建构与思考     

李敏 《洛阳师范学院学报》2008,27(4):148-151

随着全国大学英语教学改革的启动和《大学英语课程教学要求》的颁布,海南师范大学对大学英语测试体系进行了改革,将口语测试纳入每学期的期末考试。分析2006级非英语专业大学生已参加的大学英语(一)(二)(三)的口试,发现口试的话题能够联系学生的生活,但有些试题馈入方式缺乏真实情景,输出形式缺乏交互性,评分标准存在不足。针对以上情况,改进完善大学英语口语测试体系应当在考试设计方面体现交际性,在口语测试效度方面应避免考生背答案现象,提高测试的评分信度,设计客观的评分标准。  相似文献   

Mean Effects of Test Accommodations for ELLs and Non‐ELLs: A Meta‐Analysis of Experimental Studies     

Maria Pennock‐Roman  Charlene Rivera 《Educational Measurement》2011,30(3):10-28

The objective was to examine the impact of different types of accommodations on performance in content tests such as mathematics. The meta‐analysis included 14 U.S. studies that randomly assigned school‐aged English language learners (ELLs) to test accommodation versus control conditions or used repeated measures in counter‐balanced order. Individual effect sizes (Glass's d) were calculated for 50 groups of ELLs and 32 groups of non‐ELLs. Individual effect sizes for English language and native language accommodations were classified into groups according to type of accommodation and timing conditions. Means and standard errors were calculated for each category. The findings suggest that accommodations that require extra printed materials need generous time limits for both the accommodated and unaccommodated groups to ensure that they are effective, equivalent in scale to the original test, and therefore more valid owing to reduced construct‐irrelevant variance. Computer‐administered glossaries were effective even when time limits were restricted. Although the Plain English accommodation had very small average effect sizes, inspection of individual effect sizes suggests that it may be much more effective for ELLs at intermediate levels of English language proficiency. For Spanish‐speaking students with low proficiency in English, the Spanish test version had the highest individual effect size (+1.45).  相似文献   

Predicting College Performance of American Indians: A Large‐Sample Examination of the SAT          下载免费PDF全文

Siwen Shu  Nathan R. Kuncel  Paul R. Sackett 《Educational Measurement》2017,36(2):24-33

Extensive research has examined the validity and fairness of standardized tests in academic admissions. However, due to their underrepresentation in higher education, American Indians have gained much less attention in this research. In the present study, we examined for American Indian students (1) group differences on SAT scores, (2) the predictive and incremental validity of SAT over high school grades, (3) the effect of socioeconomic status on SAT validity, (4) differential prediction in the use of SAT scores, and (5) potential omitted variables that could explain differential prediction for American Indian students. Results provided evidence of predictive and incremental validity of SAT scores, and the validity of SAT scores was largely independent of socioeconomic status. Overprediction was found when using SAT scores to predict college performance and it was reduced when including high school grades as an additional predictor. This study provides substantial evidence of the validity and fairness of SAT scores for American Indians.  相似文献   

Validity and reliability of a low-cost digital dynamometer for measuring isometric strength of lower limb     

Natalia Romero-Franco  Pedro Jiménez-Reyes  Juan A. Montaño-Munuera 《Journal of sports sciences》2017,35(22):2179-2184

Lower limb isometric strength is a key parameter to monitor the training process or recognise muscle weakness and injury risk. However, valid and reliable methods to evaluate it often require high-cost tools. The aim of this study was to analyse the concurrent validity and reliability of a low-cost digital dynamometer for measuring isometric strength in lower limb. Eleven physically active and healthy participants performed maximal isometric strength for: flexion and extension of ankle, flexion and extension of knee, flexion, extension, adduction, abduction, internal and external rotation of hip. Data obtained by the digital dynamometer were compared with the isokinetic dynamometer to examine its concurrent validity. Data obtained by the digital dynamometer from 2 different evaluators and 2 different sessions were compared to examine its inter-rater and intra-rater reliability. Intra-class correlation (ICC) for validity was excellent in every movement (ICC > 0.9). Intra and inter-tester reliability was excellent for all the movements assessed (ICC > 0.75). The low-cost digital dynamometer demonstrated strong concurrent validity and excellent intra and inter-tester reliability for assessing isometric strength in the main lower limb movements.  相似文献   

Laboratory predictors of uphill cycling performance in trained cyclists     

Arthur Henrique Bossi  Pedro Lima  Jorge Perrout de Lima  James Hopker 《Journal of sports sciences》2017,35(14):1364-1371

ABSTRACT

This study aimed to assess the relationship between an uphill time-trial (TT) performance and both aerobic and anaerobic parameters obtained from laboratory tests. Fifteen cyclists performed a Wingate anaerobic test, a graded exercise test (GXT) and a field-based 20-min TT with 2.7% mean gradient. After a 5-week non-supervised training period, 10 of them performed a second TT for analysis of pacing reproducibility. Stepwise multiple regressions demonstrated that 91% of TT mean power output variation (W kg^?1) could be explained by peak oxygen uptake (ml kg^?1.min^?1) and the respiratory compensation point (W kg^?1), with standardised beta coefficients of 0.64 and 0.39, respectively. The agreement between mean power output and power at respiratory compensation point showed a bias ± random error of 16.2 ± 51.8 W or 5.7 ± 19.7%. One-way repeated-measures analysis of variance revealed a significant effect of the time interval (123.1 ± 8.7; 97.8 ± 1.2 and 94.0 ± 7.2% of mean power output, for epochs 0–2, 2–18 and 18–20 min, respectively; P < 0.001), characterising a positive pacing profile. This study indicates that an uphill, 20-min TT-type performance is correlated to aerobic physiological GXT variables and that cyclists adopt reproducible pacing strategies when they are tested 5 weeks apart (coefficients of variation of 6.3; 1 and 4%, for 0–2, 2–18 and 18–20 min, respectively).  相似文献
