概念是数学知识中最普遍的形式,是数学内容的基本点,是导出定理、公式、性质、法则的出发点,是建立学生认知结构的着眼点.所以概念的学习是数学学习的核心,概念的教学是教师落实基础的关键,是学生打好基础的首要环节.因此,在概念教学中,教师一定要以学生已有的认知基础为出发点,加强概念的引入与生成,引导学生主动探索,真正理解概念,在概念运用的过程中培养学生分析和解决问题的能力,只有
Concept is the most common form of mathematical knowledge, is the basic point of mathematical content, is the starting point for the derivation of theorems, formulas, properties, laws, and is the focus of the cognitive structure of students, so the concept of learning is the core of mathematical learning, concepts Is the key to teachers to implement the foundation and is the primary link for the students to lay a good foundation.Therefore, in the concept teaching, teachers must take students’ existing cognitive foundation as a starting point to strengthen the introduction and generation of concepts to guide students to take the initiative to explore , Truly understand the concept of the concept of the process of using students to develop and analyze the ability to analyze and solve problems, only
