解题,也应发展学生的数学语言能力   总被引:1,自引:0,他引:1  
数学的基本意义在于为科学研究提供必要的语言.解题,作为中学数学教学活动最基本的形式,其结果不仅是对学生知识观念层面、创造能力层面、思维品质层面的评价,而且也是对学生科学语言层面的评价.因此,解题教学要引导学生理解数学语言,并能应用数学语言进行数学材料的组织、表达.下面拟谈谈在中学解题教学中发展学生数学语言能力的有关做法.  相似文献

一、理念背景 《数学课程标准》强调数学活动要从学生已有的生活经验出发.让学生亲身经历将实际问题抽象成数学模型,并进行解释与应用的过程。我对数学教学生活化进行了尝试与研究,力求让学生从身旁熟悉的事情中发现数学,通过身边的事情学习数学.把数学知识应用到自己的生活中去,收到了一些较好的教学效果。  相似文献

数学作为科学的语言,作为推动科学向前发展的重要工具,在人类发展史上具有不可替代的作用。学习数学,不能仅仅停留在掌握知识的层面上,而必须学会应用。只有如此,才能使所学的数学富有生命力,才能真正实现数学的价值。数学教学应该尽可能展现数学怎样从实际背景材料中抽象出来,又怎样应用于解决实际问题  相似文献

复习,就是把学过的东西再学习,使之巩固。根据人的遗忘规律及学生认识事物的特点,复习是必不可少的。以小学数学复习课"大数的认识"为案例,通过教学中的几个片段,对课堂教学进行诊断与分析,从而寻求优化小学数学复习课的有效策略。  相似文献

新课程关注学生科学的数学学习方法的形成,重视培养学生的自主学习能力,“倡导自主探索、动手实践、合作交流、阅读自学等学习数学的方式”.数学阅读在培养学习兴趣、提高自主学习能力等方面所起到的作用已得到教师的普遍认同.但数学阅读教学的开展往往还只停留在新授课对教材的阅读以及课外对阅读材料的阅读等层面,在高三复习课中研究则更少.本文结合具体案例谈数学阅读在高三复习课中的应用.  相似文献

数学语言为教学交流提供了科学的保障,从语言层面探讨学生数学素养 培养具有重要的意义,然而,中学数学语言教学的现状并不令人满意,从微观的角度来考虑,数学教师应重视对学生数学语言的阅读教学,数学语言的语义教学,数学语言的转换教学。  相似文献

试论数学"探究性学习"教学的基本过程   总被引:2,自引:1,他引:2  
数学科学探究包含两个层面:数学科学探究的基本精神与基本程序.数学探究教学是对这两个层面的模拟.数学探究教学的基本过程中的环节主要是:问题的提出,建立猜想与形成命题,科学解释与证明,评价与交流应用.每一教学环节有各自的教学功能.  相似文献

义务教育《数学课程标准》的总体目标之一是:“通过义务教育阶段的数学学习,使学生能积极参与数学学习活动,对数学有好奇心与求知欲。”孩子对自然与社会现象的好奇心、求知欲是一种重要的素质,它可以使一个人不断地学习,不断地得到发展,还可能使一个人走进科学的殿堂。义务教育阶段的数学教育就是要培养学生亲近数学、了解数学、谈论数学,对数学现象保持一定的好奇心。那么,如何激发、培养学生的这一好奇心、求知欲呢?俗话说:万事贵乎始。我们完全有必要在开课之时,即课堂导入上下一番工夫。下面几种课堂导人方法是笔者多年来数学教学实践的几点经验总结,仅作抛砖引玉。  相似文献

数学教学,尤其是数学的课堂教学,过去是、现在是、将来仍是数学教育活动的基本构成部分.树立并坚持科学的数学教学观,领悟并形成科学的数学教学理念,关注并凸显人在数学领域的认识力和发展力,准确地把握数学的大观点和核心概念,强调数学思想与方法的融合,重视数学知识体系的建构与结构化的梳理,坚定不移地在“教什么?为什么教?怎样教,教得如何?”等诸多方面进行理性的建构性联结与行为探索,这既是“学会数学教学”的一种基调,也应当成为在新课改背景之下,处在各种思想与理念风起云涌的时代对数学教学根本性认识的一种认同与坚持.这既是对数学教学有效性在思想认识层面上的一种基本而又理性的要求,也是对所有从事数学教学工作的人们在理论层面上的一种引导.  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

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献
