文化视角下的数学课堂教学

课堂教学文化是数学课堂教学特有的文化,它是一种特殊文化、综合性文化、情境性文化,持久性文化和以理性思维为主流的文化。数学课堂数学文化建设应立足于:以学生为主体的课堂学习文化,消除数学课堂教学文化是教师的主权的文化的意识等;建立整体的数学课堂文化、重视数学生态课堂的形成,构建充满理性精神的数学课堂,构筑和谐文化交流的氛围等。     

为数学课堂添上一笔人文的色彩

数学作为一种文化,被越来越多的人关注并认同,《数学课程标准》中明确提出作为人类文化的数学,其内容、思想、方法和语言都是现代文明的重要组成部分,数学已成为人类理性文明高度的结晶,作为以传承数学知识和数学文明为要义的数学课堂,其课堂教学行为自然不能局限于“知识的传授”,而应以“学生为本”,培养学生的理性精神,凸现人文理念。     

儿童数学课堂文化“三转变”

数学课堂文化是师生在数学教学活动中表现出来的人际关系、行为方式、思维方式和价值取向.教师与学生是两个平等的文化主体,数学课堂文化主要形成于这两个主体之间开展的数学教学活动.儿童数学课堂文化是教师、儿童思维方式和行为方式的总和,是课堂教学的“土壤”,是课堂教学存在、运行和发展的“元气”,是课堂教学的活力之根和动力之源.     

如何提高小学数学课堂教学效果

《数学课程标准》中指出:“数学教学是数学活动的教学,是师生之间、学生之间交往互动与共同发展的过程.”课堂教学是学生获取科学文化知识的主阵地,因此,教学质量如何,主要取决于课堂教学效果.怎样才能较好地提高数学课堂教学效果呢?笔者认为应从以下几点入手: 一、重视课堂导入,提高课堂教学效果 俗话说:“良好的开端是成功的一半.”     

让小学数学课堂充盈“诗情画意”

数学与文化的融合,是当今教育的时代追求.数学文化体现数学价值,与现在倡导的“人人学习有价值的数学”理念,步伐是一致的.要让学生在数学文化的底蕴下,体验有价值的数学观,这就要求我们打破传统墨守成规的课堂教学模式,建立创新型的、有价值的、有文化内涵的数学课堂.这样的数学课堂简单来说,就要充盈“诗情画意”.     

在小学数学教学中渗透数学文化

数学文化是数学知识、精神、思维等文明的综合。数学文化包罗万象,有数学史、数学家的轶事乃至数学课堂形态等。在小学数学教材中,有“你知道吗”“数学广角”“数学园地”等板块,这些都体现了数学文化,本文就数学文化在小学数学课堂教学中的渗透策略作如下探寻。     

关于建构主义与数学教育理论的学习与思考

本文针对传统数学教学理论作理性思考，通过对“应试教育”、传统课堂教学设计理论的审视和反思，以建构主义基本理念、数学观、学习观、教学观等理论为指导，探讨素质教育的数学课堂体系构建、教学设计、课堂教学创新等问题。     

以节奏调控理性,把握数学化教学

数学课堂教学的节奏应与知识的逻辑生长点齐头并进,应与儿童的认知特点遥相呼应,也应该与课堂生成相得益彰.数学化特征明显且高效的课堂,必定是这三者不偏不废、融合共生的课堂.因此,课堂的节奏调控,也就顺理成章地成了理性把握数学课堂教学的“着力点”. 一、“有条不紊”——不急于自主学习 自主学习是学生借助于已知的内容,对未知领域作出的初步建构过程.“知己知彼,百战不殆.”在组织自主学习实施之前,要先探明学生的“真实状态”,如知识储备、经验迁移和情感调动等方面.自主学习既不能随意而为,也不能为赶时间急着直奔主题.     

关于数学课堂教学文化的反思

数学课堂教学文化是数学课堂所特有的文化,对初中课堂数学教学文化的反思,是为了弥补当前以学生为课堂主体文化的缺失,建设以学生为课堂主体地位,并能够有效展开自主学习的高效课堂教学.在使学生树立问题意识的基础上,给予学生更广阔的视野,以全面提升初中生的综合能力素质,实现数学课堂教学的文化育人目标.本文首先对当前初中数学教学文化进行了反思,然后为初中数学课堂教学文化的建设提出建议,以供参考.     

课程思政视角下“直线的一般式方程”的设计与反思

课程思政有利于落实“立德树人”这一根本任务.文章以“直线的一般式方程”为例,在课堂中潜移默化地融入“理想信念”“情感态度”“理性精神”和“个性品质”等思政元素,实现课程思政与数学教育的深度融合,借助数学文化内涵、数学辩证因素、数学社会现实这3种路径开发了数学学科的思政功能和育人价值.     

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.

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。     

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.

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.
