数学概念是数学知识的基础，准确理解数学概念是学生学好数学的关键，这也是中职数学教学的重点内容，而概念教学也需要好的问题情境的导入.基于此，本文将把“对数”作为研究案例，从教学目标和学生心理出发，探讨如何有效地设计问题串，以此帮助学生突破学习重难点，促进对概念的理解与掌握. 相似文献

概念教学在整个数学教学中占有重要的地位,而数学概念的理解是概念教学的中心环节。要让学生理解数学概念,就是让其真正掌握概念的本质属性。本文从运用变式突出本质、反面衬托促进理解、多层次抽象概括、简练语言表述定义、与相近概念进行比较等五个方面来阐述如何引导学生理解数学概念。 相似文献

概念是最基本的思维形式。数学中的命题，都是由概念构成的，数学中的推理和证明，又是由命题构成的。因此，数学概念的教学，是整个数学教学的一个重要环节。正确的理解数学概念，是掌握数学知识的前提，数学概念好比支点，而数学法则、定理好比杠杆。可见概念的重要性。初中阶段尤其是初一，概念较多，怎样组织教学，才能使学生更好的掌握呢？本人在多年教学中，总结出概念教学的三注重，收到了良好的效果。 相似文献

掌握数学概念是开展数学思维的基础，学好数学概念才能正确进行判断、分析、推理、运算，有效解决数学问题。数学概念比较抽象，表达语言高度精练。在当前的初中数学教学中，还有很多老师采用“展示概念一讲解概念一理解概念一巩固概念”的固定模式进行概念教学，方式死板单调，缺乏生机和活力，导致课堂气氛沉闷，学生失去学习兴趣，教学效果不佳。因此，数学教师需要转变教学方式，精心设计教学，从初中学生的心理特征、认知特点出发，在概念引出、形成、巩固、深化阶段，将静态的概念教学动态化，让学生获得充分的学习体验，增强对概念的理解，提高教学效果。 相似文献

数学概念是客观事物中数量关系和空间形式本质属性的反映,理解好数学概念是学生学好数学的前提.概念教学作为小学数学教学的起始环节显得非常重要,概念教学的质量决定小学数学教学的质量.但有不少教师对数学概念的教学力不从心,觉得难教,以致教学效果不理想;学生对数学概念觉得特别抽象且难以理解,往往不能正确把握概念的内涵和外延,导致对概念的错误理解和应用.那么,教师应如何进行数学概念的教学呢? 相似文献

美国数学教育家杜宾斯基提出的APOS理论是一种建构主义的数学学习理论,他将数学概念的建构分为Action、Process、Object、Scheme四个阶段.在对该理论的认识基础上,结合高职学生数学学习认知的心理特点,对化工专业高等数学概念的教学进行探讨,并就如何进行数学概念教学设计作了探索,使学生主动建构其概念体系. 相似文献

There is widespread belief that computers should be used for the teaching and learning of mathematics. Research indicates that computers are primarily used in mathematics classes: (1) to reinforce previously taught concepts, (2) to allow students to construct computer programs to simulate mathematical techniques known to the student and (3) to explore mathematical microworlds encompassing mathematical ideas and concepts normally known to the student. Furthermore, it is said that pre-service teachers should experience the learning of mathematical ideas and concepts of which they had no prior experience in environments in which computers are just one of the resources available for exploring and experimenting with these ideas and concepts. How should these learning environments be constructed so that pre-service teachers are sensitised to the value of doing mathematics in such environments? Is a student's understanding of novel mathematical concepts enhanced when s/he explores it in a computer-enriched environment? An experiment with pre-service teachers was carried out in a college of education for blacks in South Africa. This article describes the insights gained from this experiment. 相似文献

Technology according to the National Council of Mathematics plays a special role in teaching and learning mathematics. Technology when used effectively can deepen mathematical understanding and lead to greater abstraction. But, not all uses of technology lead to this desired result. Defining cognitive and mathematical fidelity and using it to determine which Web-based formats lead to greater generalizing and abstraction will help in understanding why interactive math objects empower teachers to build a better, deeper understanding of math concepts. 相似文献

We analyze the interrelations between prospective and practicing teachers' learning of the mathematics of change and the development
of their emerging understanding of effective mathematics teaching. The participants in our study, who were all interested
in teaching secondary mathematics, were mathematics majors who had significant formal knowledge of the fundamental concepts
of calculus prior to taking our courses, but who often experienced and expressed procedural orientations toward the teaching
of mathematics. To address this difficulty, we developed novel computer-based activities to challenge the participants' mathematical
understandings and required them to use technology during short teaching episodes they conducted with younger students. To
analyze our participants' understandings, we developed a framework that juxtaposes the roles of the participants as students
and teachers, and their understanding of mathematics and of pedagogical strategies. Our analysis of the participants' views
from these different perspectives enabled us to see simultaneously the intertwined development of subject matter insights
and specific views of teaching.

This paper explores the nature of the language used when teaching mathematics to young children. It proposes that an important part of the teaching of a mathematical concept is the introduction of specific terminology. Children may need to be taught new meanings for already familiar words. The timing of these introductions to new words or meanings is critical to their understanding of the concepts being taught. It will be argued that there are two aspects of the children's learning that need to be considered. First, their understanding of the concept being introduced, and secondly, their learning the appropriate word to describe that concept. By assessing children's understanding of new mathematical concepts through their own use of the terminology, the teacher can then negotiate new meanings with them through practical experiences, introducing new word meanings only when the concepts have been understood. 相似文献
