中学数学的学习,对很多学生来说是抽象的,灵活的不易懂的,而数学概念的学习是中学数学中学生学习的一项重要的内容,是基础知识和基本技能教学的核心,正确理解概念是学好数学的基础,而且也是构成数学规律,建立数学公式和完善数学理论的基础和前提。一、充分了解学生具有的前概念是转化前概念的前提传统的教学方式使得教师往往根据自己的经验,按照课本的逻辑顺序讲授课本知识,不注重了解学生已有的知识情况,很难发现学生存在的前概念。学生头脑中的前概念广泛存在而
Middle school mathematics learning, for many students is abstract, flexible and difficult to understand, and the study of mathematical concepts is a secondary school mathematics learning an important part of the basic knowledge and basic skills teaching the core, a correct understanding of the concept It is the basis for learning mathematics, but also the basis and premise for composing the law of mathematics, establishing mathematical formulas and improving mathematical theory. First, to fully understand the preconditions that students have before the concept of preconditions The traditional teaching methods make teachers often according to their own experience, in accordance with the logical order of textbooks to teach textbook knowledge, do not pay attention to understand the existing knowledge of students, it is difficult to find students Existent concept The preconceptions in students’ minds are widespread
