基于建构主义的网络英语学习模式设计

建构主义是网络英语学习模式的理论基础,现代网络多媒体技术的发展为其提供了技术支持;基于网络的英语学习模式应包括:建立一个学习社区;根据课程内容创设情境;丰富的信息资源;设计重视学习者的语言能力的测试评价。     

Webquest:一种探究性的网络学习活动

Webquest是一种基于建构主义理论产生的、以探究为取向的网络学习活动。在该活动中，教师设定一个与学习课程相关的、具有一定吸引力的主题，并将与该主题相关的资源进行整合后提供给学习者，学习者按照教师设定的主题，分别从不同的角度对问题进行探讨，最后通过互相交流、讨论合作或独立完成与主题相关的学习。Webquest强调学习的情境性、学习的自主性和学习的协作性，强调学习者正确合理地利用资源，在原有的知识结构上建构新的知识，这些特点与远程教育的学习特点相一致。在远程教育中合理运用Webquest具有非常重要的实际意义。     

Teaching Sacred Texts in the Classroom: The Pedagogy of Transmission and the Pedagogy of Interpretive Facilitation

Empirical research in Jewish education has found almost exclusive use of transmission pedagogy among Jewish studies teachers. This study hoped to fill out the empirical landscape by studying Jewish studies teachers who prioritize student-driven interpretation. It followed six Jewish studies teachers in four different Jewish elementary schools who all professed a commitment to student-driven textual interpretation. It found that in such classrooms there was a clear pattern of teaching moves. This article offers a detailed portrait of the previously undocumented Jewish studies pedagogy, interpretive facilitation.     

认知建构视角下交互式信息检索模型研究

[目的/意义]信息检索本质上是一个认知过程,研究促进用户认知的交互式信息检索模型具有重要意义。[研究设计/方法]以建构主义理论为指导,以促进用户的认知发展为研究目标,构建了以信息空间层、用户空间层和界面交互层为顶层分析框架的交互式信息检索模型,并开发了原型系统。[结论/发现]实验结果表明原型系统能有效地促进用户对信息空间的探索与挖掘,帮助用户积极主动地进行认知建构,发展认知空间。[创新/价值]将认知建构理论运用于信息检索领域,从交互设计方面对检索系统提出了改进建议,以更好地提供认知支持。     

Rethinking Polanyi’s Concept of Tacit Knowledge: From Personal Knowing to Imagined Institutions

Half a century after Michael Polanyi conceptualised ‘the tacit component’ in personal knowing, management studies has reinvented ‘tacit knowledge’—albeit in ways that squander the advantages of Polanyi’s insights and ignore his faith in ‘spiritual reality’. While tacit knowing challenged the absurdities of sheer objectivity, expressed in a ‘perfect language’, it fused rational knowing, based on personal experience, with mystical speculation about an un-experienced ‘external reality’. Faith alone saved Polanyi’s model from solipsism. But Ernst von Glasersfeld’s radical constructivism provides scope to rethink personal tacit knowing with regard to ‘other people’ and the intersubjectively viable construction of ‘experiential reality’. By separating tacit knowing from Polanyi’s metaphysical realism and drawing on Benedict Anderson’s concept of ‘imagined communities’, it is possible to conceptualise ‘imagined institutions’ as the tacit dimension of power that shapes human interaction. Whereas Douglass North claimed institutions could be reduced to rules, imagined institutions are known in ways we cannot tell.     

论基于建构主义学习理论的MCAI课件

基于建构主义的新型教学模式和教学改革的结合

建构主义(constructivism)也译作结构主义，是认知心理学派中的一个分支，是西方教育心理学的最新教学理论。建构主义源自关于儿童认知发展的理论，由于个体的认知发展与学习过程密切相关，因此利用建构主义可以比较好地说明人类学习过程的认知规律。建构主义强调以学生为中心，强调学生对知识的主动探索、主动发现和对所学知识意义的主动建构。本文阐述了建构主义学习理论及教学思想，建构主义的教学模式。建构基于建构主义的教学模式的理论基础并阐述了深化教育改革，培养高素质人才的可行性及必要性。不难看出，建构主义对深化教育改革，培养高素质人才有着深远的影响和积极的作用。     

Degradation kinetics and mechanisms of phenol in photo-Fenton process

Phenol degradation in photochemically enhanced Fenton process was investigated in this work. UV-VIS spectra of phenol degradation showed the difference between photo-Fenton process and UV/H2O2, which is a typical hydroxyl radical process. A possible pathway diagram for phenol degradation in photo-Fenton process was proposed, and a mathematical model for chemical oxygen demand (COD) removal was developed. Operating parameters such as dosage of H2O2 and ferrous ions, pH, suitable carrier gas were found to impact the removal of COD significantly. The results and analysis of kinetic parameters calculated from the kinetic model showed that complex degradation of phenol was the main pathway for removal of COD; while hydroxyl radicals acted weakly in the photo-Fenton degradation of phenol.     

建构主义对复变函数与积分变换教学的启示

建构主义学习观认为学习是学习者在一定情景下主动建构的过程.建构主义学习观下的教学活动应突出学生的主动性,强调让学生在一定的情境下以合作的方式进行意义的建构.建构主义教学观为复变函数与积分变换的教学提供了重要的指导意义.     

基于互联网的英语文化交流与合作写作训练研究

网络交流环境下的合作写作是一种基于互联网的文化交流和写作互助的学习模式。本文从建构主义学习理论出发,用实证研究的方法分析得出网络交流环境下的合作写作训练有利于提高学生的写作水平。研究的目的在于寻求一个以网络为交流平台,通过英语合作写作的训练培养学生的合作能力、自主学习能力和英语应用能力的有效途径。
