数学思维是对数学对象的本质属性和内部规律的间接反映。并按照一般思维规律认识数学内容的理性活动。
首先,就是数学思维的特征：概括性、问题性、相似性。这正体现了数学的美之所在。在数学教学过程中,假如注意经常发掘教材中的数学美并能引入适当地示例,就能把学生领进数学美的乐园,陶冶他们的情操,激发他们的学习兴趣,提高学生感受美和鉴赏美的能力,逐步使学生学会欣赏美和创造美。 相似文献

数学是一门美的科学。数学概念的简单化、统一性,结构系统的层次性、协调性、对称性,数学练习、数学命题的结合性、概括性都渗透着美。可以说,数学教学中到处渗透着美的教育,而审美教育对数学教学本身而言意义重大,数学教学正是在审美情感支配下对数学美的追求。因此,在数学教学设计中应尽可能挖掘数学内容中美的因素,并进行“美化处理”,也就是采用审美手段对教材进行诸如分、合、增、删的调整,从而提高数学教学的启发性、趣味性,促使学生乐学数学。一、创设情境,启发多思,营造情境美课堂是教师与学生、学生与学生思维碰撞的场所。在课堂上… 相似文献

数学蕴涵丰富多彩的美的因素。数学美的主要内容有五个方面,即简单性、对称性、相似性、和谐性(或统一性)与奇异性。“以美启真”是指用美的思想去开启数学真理,用美的方法去发现数学规律,解决数学问题。用数学美的五性去考察数学对象,思考数学问题是数学思维的美学方法和解题策略。美的观点一旦与数学问题的条件与结论的特征结合,思维主体就能凭借已有的知识和经验产生审美直觉,从而确定解题的总体思路或入手方向。因此,美的启示在解决问题的思维过程中能起到宏观指导的决策作用。一、追求简单性,探索解题捷径数学是客观事物的量的关系和空… 相似文献

新的数学课程标准中，强调要让学生领会数学的美学价值，因此数学教学过程中适时渗透数学美的知识和进行数学审美教学是很有必要的．数学美的简单性、对称性、统一性、和谐性、奇异性等特征要通过审美者对特定的数学对象的审美活动反映出来．数学美与数学教学整合的根本目的就是要实现数学学习过程与数学审美过程的统一． 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

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 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

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
