变换思维的视角谈创新解题

数学解题教学可以分为不同层次进行,但对学生思维开发较为有利的是创新解题,这种解题方式尽管不能面向所有学生推广,但是对优秀学生思维的开发是一种不可或缺的必备手段.     

浅谈数学解题教学中的“求同存异”思维

培养学生的创新思维和创新能力是新课程高考对学生的要求,同时要求学生要有扎实的数学基础知识和基本方法。实现这些要求的基本途径是解题。在解题教学中培养学生的"求同存异"思维,既可以巩固数学基础知识提高解题能力,又可以培养学生的创新思维。     

注重解题后再探究 培养学生创新思维

解题后再探究,是数学解题教学的一个重要环节,是培养学生创新思维的一个有效途径．从两个大方面谈了培养学生的思维：发散思维以及收敛思维;从八个小方面谈了怎样进行解题后的再研究,阐述了教师引导学生进行解后再探究的重要性以及解后探究培养学生的创新思维．     

学生解题创新与守旧的行为差异

学生在解题上的创新与守旧似乎是泾渭分明的．创新解题表现为活、巧、新,独辟溪径；守旧解题则表现为死、呆、旧,生搬硬套．但似乎又是一步之遥的事,它们都渊源于经验,只是在思维定势上才开始分道扬镳．思维定势是指对活动的一种内部准备状态,它是由重复某种态度、认知操作或行为方式时产生的．思维定势的负迁移不仅影响对事物的知觉、评价,而且也影响着解决问题的方式和效果．本文对学生解题创新与守旧的行为差异作一些探讨．     

注重解题后再探究培养学生创新思维

应注重在解数学题中培养学生的思维创新素质

数学解题中的思维创新,是在掌握好常规思维的基础上进行思维层次提高,即针对题目本质特征采取最优于常规思维的、灵活的、简单的方法解题。 下面就选择题、填空题、解答题谈谈学生思维创新素质的培养。     

拓展·延伸·创新——初中数学解题教学中学生创造性思维的培养

创造性思维指的是在感知、记忆、思考、联想的基础上展开的高级心理活动,这一思维的形成往往需要较长时间的培养、锻炼。在初中数学解题教学中培养创造性思维,对于提高学生的解题效率与解题质量有着重要意义。文章基于教学实际情况,采取案例分析法对培养学生创造性思维的方法展开分析,指出通过拓展常规习题教学模式、延伸常规习题教学内容、创新解题教学方法培养学生的创造性思维,希望能够为数学教师提供参考。     

注重数学解题中的思维创新

<正> 数学解题中的思维创新,是在常规思维的基础上进行的高层次思维,这种思维方式在解题活动中表现为结合问题本质特征采取优于常规思路的、灵活的、简单的解题方法. 下面就选择题、填空题、解答题谈谈学生思维创新素质的培养.     

培养中学生数学思维能力的体会

中学数学的首要任务是加强解题训练。解题是数学的心脏,培养数学思维能力是核心。发展学生的思维,考虑认知结构、思维方式,细心引导、精心设计、关注创新、优化教学。     

Western and Eastern culture differences in commercial field

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.

团图为数的图中的闭团贯数

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.

漏洞百出的教育

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?     

Social and Cultural Influence on Word Meaning

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.     

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。     

只要努力,不要后悔

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.
