长期以来,由于受应试教育的影响,不少教师在教学中重解题、轻概念,造成数学概念与解题脱节的现象。有些教师仅仅把数学概念看作一个名词而已,认为概念教学就是对概念作解释,要求学生记忆。而没有看到像函数、向量这样的概念,本质是一种数学观念,是一种处理问题的数学方法。一节“概念课”教完了,也就完成了它的历史使命,剩下的是赶紧解
For a long time, due to the influence of exam-oriented education, many teachers re-examined questions and light concepts in teaching, resulting in the phenomenon that the concept of mathematics is out of touch with the problem solving. Some teachers only consider the concept of mathematics as a noun. They think that concept teaching is to explain the concept and ask students to remember it. Instead of seeing concepts such as functions and vectors, the essence is a mathematical concept, a mathematical approach to the problem. After a section of the “concept lesson” is completed, it will complete its historical mission, and the rest will be resolved quickly.
