概念是数学教材体系的重要组成,也是数学的基础.纵观新人教版初中数学教材,数学概念比较多,又比较抽象,它影响着学生数学能力的发展.概念虽然以精炼的文字概括出现在教材里,但想理解高度概括的语言表达对初中生来说有一定难度.教师要把握概念的本质属性,有效搭建平台激活概念教学,从而促进学生主动建构知识.一、联系生活实际,亲历概念形成过程在数学学习中,概念以各种知识点分布在教材的每个章节,它是学生学好数学知识的关键.初中数学教材大部分以文
Concept is an important component of mathematics textbook system, but also the basis of mathematics.Considering the new teaching version of junior middle school mathematics textbooks, mathematics concepts more, more abstract, it affects the development of students’ mathematical abilities.Although the concept of refined text summary However, it is difficult for junior high school students to understand the highly generalized language expression.Teachers should grasp the essential attribute of the concept and set up a platform to activate the concept teaching effectively so as to promote the students’ initiative construction of knowledge. Concept formation process In mathematics learning, the concept of knowledge points in a variety of distribution points in the textbook, which is the key to students learn mathematics knowledge.Most junior high school textbooks text
