浅谈数学文化在高中数学教学中的价值

文章在反思高中数学课堂教学中的实际需要,以数学文化为视角,阐述了数学文化所特有的科学和人文两方面的教育价值,提出了在教学中应树立数学的科学价值与文化价值并举的教学观、课程观,注重创设问题情景、联系数学应用、联系数学史、感悟数学美等途径的教学建议。很多人都认为数学枯燥无味,那是不懂得欣赏。当你对数学从文化思想方面去学习,就会有所感悟。     

学科整合思想在《平面向量》教学中的体现

在高中数学的教学中，要注重数学的不同分支和不同内容之间的联系、数学与日常生活的联系、数学与其他学科的联系，从而使学生对数学的科学价值、应用价值、文化价值有较为全面的认识，进而对数学的教育价值有所感悟。本文结合《平面向量》一章的教学，探讨了数学学科内整合及数学与物理等知识的整合，并对整合的方法和层面进行了一些研究。     

论数学与现实生活联系的平衡点

数学教学既提倡联系现实生活,又注重体现数学的本质和价值.过分偏向与现实生活的联系或片面讲解纯数学知识都不可能是成功的教学.数学教学要兼顾抽象的数学知识与丰富多彩的现实生活,努力寻求两者联系的平衡点.纯数学问题所占比例、有效的数学教学时间、学生数学学习的效果是寻求数学教学中数学与现实生活联系的平衡点时需要综合考虑的3个维度.     

小学数学教科书数学文化的比较研究——以《大数的认识》为例

本文通过对人教版、北师大版、苏教版、西师版四套小学数学教科书中“大数的认识”数学文化进行比较分析,研究发现,人教版中数学史料的来源更加丰富,更能体现多元文化性,采用图文并茂的形式更多,在数学史的应用上具有明显的优势;西师版教科书更注重数学与现实生活的联系方面,苏教版高度关注现实中的社会问题,人教版、北师大版对各类现实生活的关注度相对均衡些:在数学与科学技术方面,四个版本渗透生物数学、地理科学所占比例均相对较高,其中人教版最为突出;四个版本绝大部分的人文艺术仅与建筑相荧.对于教科书编写者,应汲取各个版本的特色与优势,真正发挥数学文化的教育价值与文化价值.     

让数学文化走进课堂

面对当前数学教学中普遍存在的问题和新一轮教学改革逐渐深入,越来越多的教育工作者已认识到:数学是一种文化,数学教育是数学文化的教育。在高中数学课堂教学中,应在6个方面予以重视:一是注重揭示数学知识产生、发展的全过程;二是注重数学与其它学科的联系;三是注笪数学与生活的联系;四是注重培养学生的理性探索精神;五是注笪相关数学史的引入;六是注重丰富多彩的数学活动。     

教学中如何加强数学思想方法的渗透

数学思想方法与数学知识相互联系、相互交融,不可分割,是躯体与灵魂的关系.前者对于培养人的素质、发展人的能力更具价值.在教学中,教师不仅要重视数学思想方法的渗透,注重它们与教学内容的有机结合;更应善于数学思想方法的渗透,注重教学思想方法教学的有序性和整体性.     

关于数学文化的几个问题的哲学思考

对数学文化本质的哲学分析,不仅可以使我们更深入地理解数学文化的内涵、特点、产生、发展及其与其相关事物的联系与区别,而且我们能够更深刻地理解数学文化的价值:影响人的思维;增强社会文化中的理性成分;全面认识数学及数学价值.同时,数学文化对数学教育的意义在于:可以丰富数学教育的内涵;可以作为数学知识的载体;可以作为感性认识到理性认识的桥梁.     

基于数学文化,构建高效课堂——谈小学数学课堂整合中的数学文化

在建构小学数学高效课堂时,教师不能局限于数学知识与解题方法的教学,更要注重数学文化的渗透和传承.本文从数学文化的内涵探索出发,分析了数学文化在小学数学课堂建构中的价值,并探索了数学文化与高效课堂的整合策略.     

数学文化融入高中三角函数的教学设计研究

近几年高中数学的教学工作中,数学文化一词的使用频次越来越高,教师对数学文化越来越重视,体现出数学人文价值的创新认识以及数学课程教学观念的创新变化.将数学文化融入课堂的教学活动中,体现了文化的教育价值,体现了数学文化的生命力.从数学化的角度关注数学教学的内容创新,挖掘数学文化的教育价值,这为高中数学教师的教学活动开展开启了一个特殊理解数学的角度和窗户.特别是在高中新课程标准中,也体现了数学文化教育的重要思想和理念,强调了数学与生活以及其他学科之间的联系.将数学文化和教学结合起来,可更好地让学生感悟数学的文化价值、应用价值、审美价值.本文围绕着数学文化和三角函数课堂融合的相关问题进行探讨,希望能够给教学工作人员带来一定的借鉴价值.

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?     

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.     

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.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
