浅谈初高中函数教学“脱节”及教学建议

A Brief Discussion on the "Discontinuity" of Function Teaching in Junior and Senior High Schools and the Teaching Suggestions

在新课标改革背景下,针对目前部分中学生在学习数学函数时存在学习困难的问题,本文着重对初中数学的函数教学和高中数学的函数教学不同点进行了阐述,对初中函数教学和高中函数教学的研究内容进行了分析,认为两个阶段的函数教学"脱节"是造成学生学习困难的客观原因。就这一缺陷,基于教育学知识对部分教师提出一些教学建议,希望能帮助部分中学生走出高中数学函数学习的困境。

Under the background of the new curriculum reform,in view of some high school students'difficulties in learning mathematical functions,this paper focuses on the difference between the function teaching of junior high school mathematics and that of senior high school mathematics.The content of teaching is analyzed,and it is considered that the"discontinuity"of function teaching in the two stages is the objective reason of causing students'learning difficulties.In view of this shortcoming,this paper puts forward some teaching suggestions for teachers based on pedagogical knowledge,hoping to help high school students out of the plight of function learning in senior high school mathematics.
