新课标下的高中数学函数教学被赋予了新的定义。本文从优化函数教学的方式出发,旨在让教师能够关注函数教学在高中数学的基础性地位,走出教学误区,切实深化函数教学。 The new curriculum under the high school mathematical function teaching has been given a new definition. This paper starts from the way of optimizing the teaching of functions and aims to enable teachers to pay attention to the basic position of function teaching in high school mathematics, to get out of the erroneous teaching and to deepen the function teaching.
