课堂提问是小学数学教学中重要的教学方式之一。在传统的教学模式中,课堂提问只是教师与学生间的交流,过于单调,缺乏创新,且难以调动学生学习数学的积极性,阻碍学生思维的拓展,难以达到高效课堂的目的。而有效的课堂提问不仅能促进学生主观能动性,还能激发其学习兴趣。因此,如何通过有效的课堂提问,开拓学生思维能力,这一问题成为当前小学数学教师重点思考的问题。以小学数学教学中如何利用提问进行分析,并进行阐述,让提问成为高效课堂的桥梁。 相似文献

在小学数学的教育阶段,在课堂进行提问是一种非常高效的教学方式。教师通过提问的方式既能考查学生的知识掌握程度,又能帮助学生树立自信心。学生在回答问题的时候有了更多的思考,这样学生逐步建立起学习的兴趣,教师与学生之间也形成教学的默契,学生的课堂参与感会大大的提升。在提问的过程之中,学生也是强化知识的过程。为了让课堂提问的方式更加有效地提升学生的课堂教育质量,相关教育工作者开始注重核心素养下的小学数学课堂提问的研究,在实践取得一定成效的基础上不断总结经验,逐步实现小学生数学核心素养的培育。 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
