笔者有幸听了一节某重点中学文科实验班的一位中年教师的函数课,课后颇有感触.在新课程改革的形势下,应该怎样上好一节课?怎样评价一节课?本文通过一节普通的函数单调性的教学实录向读者展示高中数学课堂教学的一个视角,并从正、反两方面对这节课做了一些评价,同时提出一些自己 I was fortunate enough to have listened to the function class of a middle-aged teacher in a key middle school liberal arts experimental class after a class, and felt quite after class. How to evaluate a class in the new curriculum reform? In this paper, a general monotonous teaching record of functions is used to show readers a perspective of high school mathematics classroom teaching, and make some comments on the class from the aspects of positive and negative aspects, meanwhile put forward some self
