以"学"为中心的教学设计要素研究   总被引:2,自引:0,他引:2  
建构主义学习理论体现了以“学”为中心的教学思想,建构主义学习环境下的教学设计是以“学”为中心的教学设计;本文回顾了以“学”为中心的教学设计的发展历程,对以“学”为中心的教学设计的内容要素进行了分析研究,并对其进行了反思.  相似文献

以建构主义为指导的教学设计原则分析   总被引:5,自引:0,他引:5  
以建构主义理论为指导的教学设计原则与传统的教学设计相比具有更大的生命力。建构主义教学设计强调要发挥学习者在学习过程中的主体性和建构性 ,重视“情境”、“协作”在学习中的重要作用。以建构主义指导教学设计 ,有利于创造性人才的培养 ,在今天具有重要的现实意义  相似文献

建构主义教学理论及其启示   总被引:18,自引:0,他引:18  
“建构”一词是瑞士心理学家皮亚杰的《发生认识论》著作中的一个概念。在当代,国外把建构主义大致分为三类,即“极端建构主义”、“个人建构主义”和“社会建构主义”。建构主义教学理论是以其学习论为基础的,主要包括:教学目标、教学原则、教学模式、教学设计等方面。这一教学论启示我们:构建适合时代需要的教学模式;确立合理的教学方法;按学生的认知规律进行设计教学。  相似文献

一、心理活动课教学设计的原则建构主义的教学设计主张教学设计应围绕学生如何学而进行,特别强调“情境创设”“协作学习”和“学习环境”的重要性。因此,在运用建构主义的理论和教学指导思想指导教学设计时,教师应着重考虑如何通过适当的学习活动创造问题情境,  相似文献

近年来,建构主义学习理论在世界范围内显示出强大的生命力,作为一种新的认识论,建构主义理论对教学产生了一定的影响。如“以学习者为中心”、“合作学习”的教学理念以及以多媒体计算机和网络通信技术为认知工具的课堂教学模式都是以建构主义为理论基础的,第二语言教学一直以来大家都在努力探索更加切实有效的教学方式。在当前讲求效率的新时代,建构主义的学习和教学观点为我们开辟了一条新的路径。本文试图运用建构主义学习理论观点,对第二语言课堂练习的设计进行探讨。  相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.  相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.  相似文献

汉字倒说     
汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。  相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language.  相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.  相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex.  相似文献
