变式教学在高中数学教学中的应用——以函数概念教学为例

On the Application of Variant Teaching to Senior High School Mathematics Teaching: A Case Study on the Teaching of Function Definition

函数的思想方法贯穿高中数学课程的始终,属于核心内容,对函数概念抽象内涵的理解深度,直接关系学生运用函数思想方法解决实际问题的能力和水平。在函数概念的教学过程中,恰当引入变式教学,借助丰富的具体例子,强化学生对映射的认识,明确函数概念的认识误区,注重拓展三种基本函数模型的应用,深化学生对函数概念内涵的认识。

The thinking method of function, as the core content, runs through the whole senior high school mathematics course, so the depth of unde^tanding the connotation of definition directly relates to students＇ ability of solving actual problems by using the thinking method of function. In function teaching, the introduction of variant teaching and rich examples can enhance students＇ understanding of function.
