具身认知把“身体参与”置于学习活动的核心位置，其理论是在反思与批判身心二元论的传统认知观基础之上发展起来的。小学数学实验体现了具身学习的基本要义，实验的情境性、操作性和探索性让具身学习成为可能。在教学中，教师要注意从具身认知的视角引导学生开展数学实验，让具身实验促进学生的数学思维进阶。 相似文献

数学反思能力是学习者在数学学习活动中对自己数学认知过程的自我意识、自我监控能力。它以反思的技能和反思的毅力为基础,并在对数学认知过程的评价、控制和调节中显示出来。它对数学认知活动起指导、支配、决定、监控的作用。对数学学习反思能力的培养,实质是培养学生数学学习的自我意识,使他们形成自我评价数学学习的习惯和能力,掌握矫正和控制数学活动过程的技能,养成良好的数学思维习惯,促进对数学思想方法的悟性。 相似文献

数学基本活动经验是指学生从事有明确数学目的活动,获得的一种感性认识、情绪体验和应用意识（具有个体认知特征的隐性知识）。这种感觉和体验会潜移默化地影响个体的认知方式和思维方法,对学生的学习具有加深理解、促进迁移、优化认知和情感激励的功能。数学课程标准（实验稿）将“数学基本活动经验”与基础知识、基本技能、基本思想提高到同等... 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
