同学们知道,全面准确地理解一个个数学概念,是学好数学的前提.对一个数学概念的理解,显然不能靠简单机械地背诵概念的文字,而是要内化概念背后的深意,并加以灵活运用.那么通过有效的途径去理解一个数学概念就显得尤为重要.对此,本文仅以对平面向量的概念理解为例,向同学们提出四点建议,以资参考. Students know that a comprehensive and accurate understanding of a mathematical concept is a prerequisite for learning mathematics.Obvious understanding of a mathematical concept can not simply by memorizing the concept of the text, but to internalize the meaning behind the concept and be flexible So it is very important to understand a mathematical concept through effective way.Therefore, this paper only makes a four-point suggestion to the students by taking the conceptual understanding of plane vector as an example.
