锚测验难度参数方差特征对测验等值的影响研究

本文使用R-2.15.2软件模拟研究锚测验难度参数方差特征对测验等值误差的影响,采用三种等值方法(链百分位等值法、Levine等值法和Tucker等值法)对锚测验不同类型的难度方差进行比较研究。结果显示,当锚测验难度方差小于全测验难度方差时,其等值的随机误差和系统误差与锚测验难度方差和全测验难度方差一致时(即锚测验为全测验的平行缩减版minitest时)的表现基本相同。因此,对锚测验而言,要求其与全测验具有相同的统计规格可能过于严格。     

How valid are 11-plus tests? Evidence from Kent

Despite profound influence of selection-by-ability on children's educational opportunities, empirical evidence for the validity of 11-plus tests is scarce. This study focused on secondary selection in Kent, the largest grammar school area in England. We analysed scores from the ‘Kent Test’ (the 11-plus test used in Kent), Cognitive Assessment Tests (CAT4) and Key Stage 2 Standardised Assessment Tests (KS2) using longitudinal data of two year cohorts (N₁ = 95, N₂ = 99) from one primary school. All the assessment batteries provided highly overlapping information, with the decisive effect of content area (e.g. verbal vs maths) over task type (e.g. knowledge-loaded vs knowledge-free). Thus, the value in differentiating ‘pure’ (i.e. knowledge-free) ability in 11-plus testing is questionable. KS2 and Kent Test aggregated scores overlapped very strongly, sharing nearly 80% of variance; moreover, KS2-based eligibility decisions had higher sensitivity than the Kent Test in predicting the actual admissions to grammar schools after Head Teacher Assessment (HTA) appeals have taken place. Finally, the use of multiple pass marks for each Kent Test component, as well as the total score, was found to increase the chance of false rejection. This study provides preliminary evidence that national examinations could be a good basis for selection to grammar schools; it challenges the use of complex admission rules and multiple decisions, and questions the value of 11-plus tests.     

外语口语测验的历史发展综述

本文总结了第二语言口语测试的发展历史,并分为三个时期展开讨论,分别命名为萌芽期、发展期以及转变与成熟期。文章指出,北美口语测验的发展以二战为契机,并在二战以后得到了快速发展,先后诞生了FSI量表、ILR量表和ACTFL大纲等重要文件。文章还探讨了当代口语测验研究四个方面的发展趋势。     

Students’ Adaptation of Study Strategies When Preparing for Classroom Tests

According to theories of students’ test preparation, students may optimize their test performance by paying special attention to important information and processing this information in ways that are appropriate to the type of questions included in the forthcoming test. However, research is unclear about the conditions under which students adapt study strategies to the demands of test preparation tasks. Moreover, little is known about the processes and abilities involved. In this article, we present a theoretical model that integrates various factors that seem relevant to strategy adaptation in test preparation, including the teacher’s intended task demands, students’ perceptions of these demands, students’ personal goals for studying, and their ability to adapt and implement strategies. The aim of our model is to stimulate further research on strategy adaptation, which may eventually provide evidence-based guidelines that could help teachers support the development of students’ strategy adaptability and use tests as learning tools.     

临床微生物检验教学中学生人文素养的培养及探索

临床实践过程中,学生人文素质的培养在临床工作中至关重要,但就目前在教学及学生实习过程中发现,关于人文素养层面的培养还远没有达到临床实践要求。微生物检验是强调专业技术和人文科学的课程,在检验专业教学及工作中蕴藏着高深的人文素养的培养资源。因此,加强检验专业学生人文素养的培养也是临床微生物检验教学改革中的重要环节。

基于OTA测评指导的最佳损伤救助方法

运动损伤后的最佳救助对于运动员的后续运动恢复能力影响极大,损伤救助的难点在于如何根据运动员的实际情况,提供最佳的救助方案。传统的救助方法采用经验和表面现象判断的方法,无法对运动员的实际情况,无法达到最佳救助,且临场方法风险大。提出一种基于最佳测试分析(OTA)测评指导的最佳损伤救助方法,采用最佳测试分析方法,对每个运动员的多项身体指标进行监测和分析,提取表征运动员身体状况的多项指标,并选择与之对应的最佳损伤救助方案,提高救助效果。采用实际的损伤运动员进行测试分析,实验结果表明,采用基于OTA测评指导的方法进行损伤救助,损伤救助的效果明显好转,具有很好的应用价值。
