函数是中学数学知识体系的重要组成部分,函数的教学有着非常特殊的意义,对高中数学教师的综合素养、专业能力和文化底蕴也是严峻的考验。笔者近日上了一节“函数概念”的公开课,上课前参阅了不少关于函数教学的文献资料,笔者一直在想,函数的教学有突破的可能吗?因此进行了尝试,通过几次的试讲、反思、修改,最终的公开课收到了很好的效果,以
The function is an important part of the middle school mathematics knowledge system. The teaching of the function has a very special significance. It is also a severe test for the high school mathematics teacher’s comprehensive quality, professional ability and cultural heritage. The author recently had an open class on the concept of “functions.” Before the class, I read a lot of literature on function teaching. I have been thinking that there is a possibility of breakthroughs in the teaching of functions. Therefore, I tried to pass several The trial lectures, reflections, and revisions have resulted in a very good result in the final open class.
