The emergence of the quantified child

Using document analysis, this paper examines the historical emergence of the quantified child, revealing how the collection and use of data has become normalized through legitimizing discourses. First, following in the traditions of Foucault's genealogy and studies examining the sociology of numbers, this paper traces the evolution of data collection in a range of significant education policy documents. Second, a word count analysis was used to further substantiate the claim that data collection and use has been increasingly normalized through legitimizing discourses and routine actions in educational settings. These analyses provide evidence that the need to quantify educational practices has been justified over long periods of time through a variety of documents and that the extent to which data governs educators’ thoughts, discourses, and actions has dramatically increased during the past century.     

Do Test Scores Buy Happiness?

Since at least the enactment of No Child Left Behind in 2002, standardized test scores have served as the primary measures of public school effectiveness. Yet, such scores fail to measure the ultimate goal of education: maximizing happiness. This exploratory analysis assesses nation level associations between test scores and happiness, controlling for a strong correlate of both, per-capita Gross Domestic Product (GDP). Controlling for GDP, the association between test scores and happiness is greatly decreased, offering reason to question the sole use of test scores as measures of school success.     

库兹涅茨假说及中国地区差距的实证研究

对库兹涅茨假说的内涵、实质进行理论表述与分析,简述了学术界关于该假说的争论,提出了该假说成立的三个隐含条件。应用“各态历经理论”,以改革开放20年来中国东、西部地区经济发展差异为实证研究对象,研究表明无论是中国东西地区人均财富差异、经济密度差异,还是经济总量差异,均符合库兹涅茨假说。文章提出中国应积极寻求发展与公平之间的平衡点与结合点,尽快培育由发展与公平“两难”境地向“双赢”局面转化的政策环境,以及中央政府充当“道德人”角色的功能作用要进一步强化的若干政策建议。     

基于RTL行为模型的测试产生及时延测试方法(英)

寄存器传输级(RTL)测试产生及时延测试是当今集成电路(IC)测试技术中亟待解决的问题和研究的热点.首先从IC逻辑测试的测试产生和IC时延测试方法这两个方面系统地综述了测试产生和时延测试领域迄今为止的主要研究成果.在RTL行为描述的测试产生方面,提出了新的RTL行为模型的描述方法:行为阶段聚类描述,并提出了基于聚类的测试产生技术.将这些技术集成到RTL级ATPG系统ATCLUB中,在提高测试产生效率及缩短测试长度方面效果显著.在IC时延测试方面,提出了一种新的可变双观测点的时延测试方法。基于该方法提出了新的时延故障诊断方法,实现和完善了可变双观测点的时延测试系统DTwDO.DTwDO提供了从时延测试到故障诊断等一系列测试工具,有效减少了测试通路数,提高了故障覆盖率,并有很高的故障定位成功率.     

第二语言习得中的逆向迁移研究

从有关语言迁移定义的回顾和三种语言迁移理论的述评可以看出,忽略逆向迁移现象的语言迁移研究显然是不够全面的。本文论述了语言迁移路径、逆向迁移研究的进展及其理论假设,希望引起对于二语习得逆向迁移研究更多的重视。

基于四级考试成绩对民办理工科学生外语学习状况的调查

语言测试不仅可以考察学生的语言能力,而且可以反映教学工作的长处和不足.基于此,对民办理工科学生的英语四级成绩进行分析,描述了这部分学生的外语学习不太令人满意的状况,从而得出结论和启示:民办学生、尤其是理工科学生的外语教学应该作出调整和变化.     

在大学英语教学中语境理论的应用——对补缺假说的验证

"补缺假说"论的提出旨在阐释外语学习的机理,强调语言的使用离不开语境,语言与语境知识的有机结合是语言能被正确、恰当、流利使用的前提.通过对"补缺假说"的验证,得出结论,即在大学英语课堂上应通过人为地补足语言的适用语境,有效地融合连用语境教学,帮助学生走出背单词、记语法的误区.     

The virtual anatomy laboratory: usability testing to improve an online learning resource for anatomy education

An increasing number of instructors are seeking to provide students with online anatomy resources. Many researchers have attempted to identify associations between resource use and student learning but few studies discuss the importance of usability testing in resource design and modification. Usability testing provides information about ease of use and resource flexibility and indicates navigational issues that contribute to extraneous cognitive load for the user. An example of usability testing for modification of an online anatomy resource called the "Virtual Lab" is presented. Usability testing was used to determine whether increased content would impair navigation through the interface. Subjects with varying levels of experience with anatomy content were recruited to assess efficiency and effectiveness (defined by usability standards) of the original resource and of the redesigned resource. Comparisons between usability evaluation of the original "Virtual Lab" (OVL) and of the redesigned "Virtual Lab" (RVL) revealed that subjects were better able to successfully complete tasks using the RVL than they were with the OVL. Results also demonstrated that subjects did not take significantly more time to successfully complete tasks with the RVL. Additionally, usability testing revealed that subjects were able to successfully complete tasks using the RVL regardless of whether they possessed prior experience with anatomy content or not. Results of this study suggest that the modified resource is more effective for users. The example presented here underscores the need for usability testing prior to resource implementation and whenever significant changes are made to a resource interface.     

冥想念动训练对肌肉力量增长的实验研究

目的:本研究应用冥想念动训练方法来提高运动员对肌群的协同控制能力,有效提高其完成运动动作时的力量。方法:16名受试者随机分成A、B两组。均进行负重屈肘练习,重量12RM,重复10次,每天3组,每组负重训练完成后,A组放松休息,B组平卧进行冥想念动训练,共训练30 d。采用美国产MERAC等速测力系统测试训练前后肱二头肌在各种收缩状态下的Peak Speed或Peak Torque来评价受试者的肌肉力量。结果:训练后,冥想念动训练的B组的等张收缩力量、等动收缩力量均要优于只进行常规训练的A组。而两组间等长收缩力量无统计学意义的差异。这可能是由于冥想念动训练方法有效地在受训者神经系统中固化了动作过程中撷抗肌的拉长或放松模式,从而明显地增加了受训者完成运动动作时原动肌与撷抗肌的合力的结果。
