语言测试理论与大学英语测试

依据Bachman和Palmer的语言测试原则,对浙江大学英语专业学生和非英语专业学生同时进行两份试卷测试。测试结果表明:CET和TEM无论对英语专业学生和非英语专业学生而言都具有区分度;非英语专业的学生并不绝对地比英语专业学生英语能力差。这两套试卷测试相关度很高,表明用统一的考试机制更能客观地反映各类学生的英语实际水平。

高职文秘专业考试制度初探

进行以"实践能力测试"为核心的考试制度改革就是要摒弃以往传统的考试制度,侧重对学生的实践能力考察,并引导学生重视知识运用能力、分析和解决问题能力、自我评价和评价他人能力及心理素质、协作精神、职业道德等。这种理念主要是培养出适应现代需要的,具有更强实践能力、创新能力和创业精神的现代化文秘人才。     

基于ANP的毕业要求达成度评价解析

毕业要求达成度是基于成果导向教育模式(Outcomes--based Education,OBE)的核心概念,对其评价的合理性直接影响到OBE教育模式的实施效果。传统的相关评价中存在教育过程性因素考查不充分、指标不独立引起的信息损失过多、评价方法使用受限、评价结果不准确等问题,而基于网络层次分析法(ANP)的毕业要求达成度评价可在一定程度上解决这些问题。该评价方法不仅有效融入了教育全过程因素,而且充分考虑了各指标间的关联性,能够反映出全部指标的相对重要度,减少了信息损失,更符合OBE中毕业要求达成度的评价要求。     

微信红包随机金额生成算法模拟及应用

构造了微信红包随机金额的模拟算法,并验证了模拟算法的有效性。通过模拟算法,产生了大量微信红包随机金额数据,分析这些数据表明:(1)微信红包随机金额呈正态分布,是在红包份数较少的情况下,表现出的一种巧合,在红包份数较多的情况下,随机金额并不符合正态分布;(2)对一个微信随机红包,概率上,每个人抢到的红包金额是相等的,即抢红包的先后次序对抢到金额的多寡没有影响;(3)对一个微信随机红包,越晚产生的随机金额,其波动范围越大,即先抢红包的人,抢到平均金额的可能性比较高,后抢的人,要么抢到较小的金额,要么抢到较大的金额。     

浅析复杂材料的提取练习效应

提取练习效应具体指学习某一内容后,进行测试比再次学习的记忆保持效果更好,即使测试后没有反馈也依然存在。研究发现对词语、篇章及技能等类型的学习都存在提取练习效应。但近年来一些研究发现复杂材料不存在提取练习效应。本文综述了有关复杂材料不存在提取练习效应的实验,并讨论了复杂材料没有出现提取练习效应的内部原因。     

Learning styles in engineering education: the quest to improve didactic practices

This article discusses a dilemma that engineering educators encounter when attempting to develop pedagogical methods: that of finding efficient and scientifically valid didactic practices. The multitude of methods offered by educational consultants is perplexing. Moreover, the popularity of commercially offered solutions such as learning styles testing makes them appear attractive. The study presents one case of application of learning styles, the consequent problems and evaluation of results. It concludes that the use of learning styles is not supported by current pedagogical theories. Practices to foster interdisciplinary understanding between learning sciences and engineering are proposed in order to improve engineering education, most notably collaborative projects between university departments.

An international comparison using a diagnostic testing model: Turkish students’ profile of mathematical skills on TIMSS-R

This study illustrates how a diagnostic testing model can be used to make detailed comparisons between student populations participating in international assessments. The performance of Turkish students on the TIMSS-R mathematics test was reanalyzed with a diagnostic testing model called the Rule Space Model. First, mathematical and cognitive skills (‘attributes’) measured by the test were determined. One hundred sixty-two items were coded in terms of their attribute involvement, creating an incidence matrix—the Q-matrix. Using the Q-matrix and the student response data, each student’s attribute mastery profile was determined. Mean attribute mastery levels of Turkish students were computed and compared to those of their American peers. It was shown that Turkish students were weak in algebra and probability/statistics. They also demonstrated poor profiles in skills such as applying rules in algebra, approximation/estimation, solving open-ended problems, recognizing patterns and relationships, and quantitative reading.

英语语言测试的批判理论分析

本文根据批判理论的观点对英语测试,特别是美国TOEFL和英国IELTS进行了历史回顾和现状分析,结果表明:影响英语测试的因素除语言学、语言教学和语言测试理论外,也受到社会政治和经济因素的制约。国外外语测试都是在一定的历史背景下发展起来的,都有其特定的历史条件和社会需求。
