Instructional Misconceptions in Acid-Base Equilibria: An Analysis from a History and Philosophy of Science Perspective

The implications of history and philosophy of chemistry are explored in the context of chemical models. Models and modeling provide the context through which epistemological aspects of chemistry can be promoted. In this work, the development of ideas and models about acids and bases (with emphasis on the Arrhenius, the Brønsted–Lowry, and the Lewis models) are presented. In addition, misconceptions (alternative and instructional ones) on acid-base (ionic) equilibria are examined from the history and philosophy of science perspective. The relation between the development of the models and students misconceptions are investigated. Finally, the hypothesis that history and philosophy could help educators anticipate students misconceptions is examined.     

论我国民办高校融资的多元化路径

改革开放后，我国的民办高等教育迅速兴起并获得了快速的发展，但资金短缺问题日渐突出，成为阻碍其进一步发展的关键因素。民办高等教育可以而且应该利用多元化融资渠道来解决其发展中的资金瓶颈问题。     

自组织是中英文认知与教育协同的机制

自组织对推动中英文认知的发展具有重要的意义,跨语言教育应当通过组织行为发挥协同效应。本文首先介绍了自组织概念、机制和特征,以及中英文认知和教育协同观的思想;然后从自组织系统对"中介语"的解释,自组织对中英文认知和教育的作用、中英文认知和教育过程中自组织存在的条件等三个方面,论证了自组织是中英文认知与教育协同发展的机制。     

浅析我国国债的挤出效应

1998年我国政府实行积极财政政策，国债规模逐年攀升。但是庞大的国债规模。并没有对私人投资产生明显的挤出效应。尽管如此，政府制定政策时还是应当慎重，应该适当控制国债的增长率，转变财政支出的结构。本文从挤出效应的作用机制入手，通过模拟我国的IS-LM模型，从实证的角度论证了国债没有对私人投资产生明显的挤出效应。     

略论中国共产党的政治容纳性

中国共产党是工人阶级的政党,同时也是执政党。坚持党的政治阶级性是维护政党权的需要,扩大党的政治容纳性是维护执政权的需要。坚持两者的辩证统一,是对党的领导和执政能力的一个考验。执政党的政治容纳性,主要体现在执政党的执政理念、组织基础、社会基础、政策主张等方面。执政党既然掌握了公共权力,那么,它就占据了公众进行利益表达和利益综合等方面的主渠道,因此必须处理好代表特定阶级、阶层和群体与代表社会整体的关系,这也要求执政党政治应具有容纳性。政治容纳性是现代政党执政规律的内在规定;中国国情需要执政党的政治容纳性。     

基于问题的学习法(PBL)在无机及分析化学课程教学中应用

基于问题的学习法(Problem Based Learning,PBL)是目前创新教学中普遍研究的一种教学方式。以"酸碱平衡和酸碱滴定"一章的教学为例,探索了PBL学习法在无机及分析化学教学中的应用。实践表明,PBL教学法能显著激发学生的学习兴趣,培养学生的自主学习能力,增强团队精神,培养创新能力,是一种值得推广的教学方法。     

佛像画初传与六朝画家的佛画创新——论曹不兴的佛像画样式转化

佛教传入中国,最早以佛像绘画的方式宣传佛法,由印度僧人带来的具有西方绘画特点的佛像绘画样式并没有产生宣传佛法的作用,但佛像画最终能在中国广泛流传,并达到了完全的像教作用,这与最早接触佛像绘画的中国本土画家有着直接的关系。在中国绘画史的记载中,最早接触佛像画的画家是三国时期的曹不兴,他的佛像画并非如许多美术史的著述中所说的完全就是西国的风格。根据佛教初传时期的史料和六朝画家的绘画风格记述,可以证明从曹不兴开始直至后来的诸多画家都对佛像画进行了改进,他们所作的佛像画与西国样式渐行渐远,并且都形成了具有本土化和时代特征的佛画样式,这些具有中国绘画特征的佛像画才是佛教在像教过程中得以流行的根本因素。

Performance of English Language Learners as a Subgroup in Large-Scale Assessment: Interaction of Research and Policy

Factors that contribute to the performance gap between subgroups and mainstream students deserve special attention. Different subgroups are faced with different sets of challenges. To understand and control for factors leading to the performance gap between subgroups and mainstream students one must clearly understand the issues specific to each subgroup. This paper focuses on assessment and performance issues for English language learner (ELL) students as a subgroup. Identifying factors affecting the performance gap between ELL and non-ELL students may help gain insight into assessment issues for other subgroups of students as well as strengthen assessment of this group.
