概念是反映事物本质属性的思维形式。正确的概念是科学抽象的结果。每一个科学概念都有其确定的内涵和外延。只有让学生对概念的内涵和外延都有了准确地了解,才是真正掌握了概念。在高中数学的教学中,我们要重视概念教学的每一个环节,经历一个实践—反思—再实践—再反思的过程,为概念教学找到一个更好的方法,洞悉概念的本质,为学生节省宝贵的学习时间,从而达到事半功倍的学习效果。 Concept is a form of thinking that reflects the nature of things. The correct concept is the result of scientific abstraction. Each scientific concept has its definite connotation and denotation. Only students have accurate understanding of the concept of connotation and denotation, is the real grasp of the concept. In high school mathematics teaching, we should pay attention to every aspect of concept teaching, go through a process of practice - reflection - practice - re-reflection, find a better way for concept teaching, understand the essence of concept and save precious for students Learning time, so as to achieve a multiplier effect of learning.
