变式教学是通过变式法的运用,使概念或者问题的非本质特征能够在不断的变化过程中呈现出来,进而将本质特征更加直观地突显出来。高中函数概念教学作为数学的主要教学内容,在理解上存在着两大误区,并且在解题过程中,也会出现各种困难,熟练地运用变式教学能够使学生更深入的建构函数概念的知识体系,并学会灵活运用这一知识体系分析并解决问题。 Variant teaching is through the use of the variant method, so that the non-essential features of the concept or problem can be presented in a continuous process of change, and then the essential features are more intuitively highlighted. As the main teaching content of mathematics, concept teaching of high school has two misunderstandings in understanding. In the process of solving problems, there will also be various difficulties. Using variant teaching skillfully enables students to construct function concepts in more depth Knowledge system, and learn to use this knowledge system to analyze and solve problems flexibly.
