Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.     

Differentials in Mathematics Achievement among Eighth-Grade Students in Malaysia

This paper examines differences in mathematics achievement among eighth-grade students using a secondary analysis of the data. The students, who are from Malaysia, had participated in the Trend International Mathematics and Science Study (TIMSS) 1999. A series of school, home, demographic and socio-economic variables were used to investigate the differences in the mean student mathematics scores. Evidence from the data shows that gender, the language spoken at home, expected educational level, family background, and home educational resources and aids have a significant influence on the students’ level of mathematics achievement.     

影响藏族双语儿童学习的社会文化心理机制研究

在化资本理论、社会资本理论、资源稀释假设等理论的指导下，结合多次赴甘南藏族地区实地调查研究，编写出《化背景调查问卷》，对影响藏族双语儿童学业成绩的各种因素进行了研究，构建了学校、社区、家庭因素与双语儿童学业成绩的关系模型。研究结果显示：社区背景良好，家庭投入越多，父母教育期望越高，父母学习辅导行为越好，越有利于提升儿童的学业成绩。     

The Bookmark Standard-Setting Method: A Literature Review

The Bookmark method for setting standards on educational tests is currently one of the most popular standard-setting methods. However, research to support the method is scarce. In this report, we review the published and unpublished literature on this method as well as some seminal work in the area of evaluating standard-setting studies. Our review highlights both strengths and limitations of the method. Strengths include its wide acceptance and panelist confidence in the method. Limitations include a potential bias to produce lower-than-intended standards and problems in selecting the most appropriate response probability value for ordering the items presented to panelists. It is clear that more research on this method is needed to support its wide use. Several areas for future research to better understand the validity of the Bookmark method for setting standards on educational tests are presented.     

大学生学习成绩与学习时间的相关性研究

对72名大三学生就学习成绩与学习时间的相关性进行了跟踪研究,结果表明:学习时间与学习成绩从总体上分析无显著相关,但较高的学业成绩必须有一定量的学习时间来做保证;学习时间的有无规律是决定学业成绩的重要因素;大学生学习时间上存在性别差异.     

对HSK部分等级的验证性研究

中国汉语水平考试(HSK)的作用之一是界定留学生进入中国大学入系学习时所应具备的汉语能力。根据有关规定,HSK三级和六级分别是进入中国大学理工西医类和文史中医类入系学习的最低标准。本文采用安哥夫、边缘组及对照组三种方法对此标准进行了验证性研究。
