数学概念在数学学习中处于基础性的地位,抽象化和形式化是它的基本特征;很多数学概念是经多重抽象而形成,和学生的认知力、已有经验相距较远;学生对其缺乏从感性到理性的认知,这是概念教学中的一个难点.郑毓信教授提倡,数学概念教学不能向学生灌输,而要求我们教师在教学中重视概念的形成过程,积极引导,探究发现,内化,拓宽,让学生主动地参与到概念的生成中来.这就要求我们教师在概念教学中要围绕概念的生成精心设置问题,引导学生对问题层层削剥,让学生带着好奇心和内驱
Mathematical concepts in mathematics learning in a fundamental position, abstraction and formalization is its basic characteristics; many mathematical concepts are formed by multiple abstractions, and students’ cognitive ability, the experience has been far apart; students to its Lacking from perceptual to rational cognition, which is a difficult point in concept teaching, Professor Zheng Yuxin advocates that the teaching of mathematical concepts can not be instilled into students, but requires our teachers to attach importance to the formation of concepts in teaching and actively guide, explore, To broaden and widen the students’ participation in the generation of concepts, this requires us teachers to carefully set the questions around the generation of concepts in the concept teaching, to lead the students to peel the layers of problems, drive
