从初高中衔接谈初中二次函数的教学

Talking About the Two Function Teaching in Junior Middle School from the Link Between Junior High School and Senior Middle School

在初高中数学教学中,对二次函数教学提出更高要求,很多学生在知识掌握过程中,无法对二次函数知识做深入的理解,在高中阶段学习中无法适应,所以对二次函数基础知识进行训练,对学生有效指导,能使学生对二次函数内容充分掌握。

In junior and senior high school mathematics teaching,the quadratic function teaching puts forward higher requirements,many students in the process of knowledge mastery,can not do in-depth understanding of quadratic function knowledge or adapt to high school learning,so the basic knowledge of quadratic function training and effective guidance to students can enable students to fully grasp the content.
