运用数学思想，加强解题训练

数学思想，是人们对数学理论及内容的本质认识，是在数学活动中处理问题的基本观点，它直接支配着数学实践活动．数学思想是数学解题方法的灵魂，是数学基础知识和基本技能提升为能力的体现，是知识转化为能力的桥梁．解题训练作为培养学生数学才能和教会学生思考的一种手段和途径，必须以数学思想为指导．领会了数学思想的精髓，就真正掌握了数学知识，就一定能提高学习效率和数学素养．因此，用数学思想强化解题训练，对于打好“双基”和加深对知识的理解、运用，以及培养学生的思维能力有着独到的优势．下面列举一些数学思想在强化解题训练中的运用．[第一段]     

关于数学思维训练教学的探讨

现代数学论认为，数学教学是数学思维的教学。思维活动的强弱，决定一个人的思维品质。在数学课堂教学中，探求问题的思考、推理论证的过程等一系列数学活动都以逻辑思维为主线，这是数学教学中实施思维训练的理论依据之一。     

数学学习的特征综述

数学是研究空间形式和数量关系的科学。由于数学的研究对象具有不同于其他科学的特殊性，因而学生的数学学习也具有不同一般学习的自身的特征。数学学习只有符合数学的特征，符合数学思维活动的特点、规律和要求，才能取得成效。数学学习又是关于人类文化知识的学习，

培养学生的数学直感 训练学生的数学直觉思维

数学直感是一种直接反映数学对象结构关系的心智活动形式,它是人脑对于数学问题的某种直接的领悟或洞察。它在运用知识块和直感时都要进行适当的加工,将脑中贮存的与当前问题相似的块,通过不同的直感进行联结。并非     

中低年级数学教学学生思维活动的训练

义务教育小学数学教学大纲提出:“学生初步逻辑思维能力的发展,需要一个长期的培养和训练过程。”因此,对学生思维能力的训练要注意以下几方面: 一、加强概念教学概念是思维的基本要素和赖以存在的基础,人类思维活动是在一定知识基础上进行的。大纲指出:“小学数学中的概念……都是基础知识,要让学生切实学好。”因此,加强数学基础知识教学就要加强数学概念教学,只有在扎实的概念教学基础上,小学生计算能     

如何提高学生的思维能力

数学教学主要是数学思维活动的教学。学生初步的逻辑思维能力的发展需要有一个长期的培养和训练过程。数学教学的思维训练，是根据学生的思维特点，结合教学内容在教学过程中实现的。课堂教学是对学生进行思维训练的主阵地，所以，要把思维训练贯穿于数学教学的各个方面。     

浅谈“数学活动课”的作用

科技在发展，时代在进步，数学应用将越来越广泛，这就要求未来的人才具帑较高的数学素质。因此，提高学生的数学素质将是战略之策。提高学生的数学素质，主要指提高学生的思维能力，以便能合理、灵活地解决问题。实践证明，培养高数学素质的学生，只靠单一化的学科课堂教学还不够，而数学活动课的开展，有利于提高学生数学素质这一目标的实现，数学活动课应以数学思维训练为核心，以活动为主要形式，做到面向全体，囚材施教，让学生在实践活动中，[第一段]

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?     

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.     

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.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.

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.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
