二次函数是初中数学的重点内容,也是高中数学的基础,在中考中函数知识占有的分数比例较大。对于初中学生而言,初涉函数,能正确理解函数的原理也有一定难度,因此教师在教学过程中要正确把握教学方式,总结教学中的难点,并且对教学方法进行反思,帮助学生更好地理解二次函数。本文首先分析了二次函数教学目标,其次指出了重点难点,并结合具体例题,反思如何帮助学生理解二次函数。
Quadratic function is the key content of junior high school mathematics, but also the basis of high school mathematics, in the senior high school entrance examination function knowledge share of a larger proportion. For junior high school students, the initial function, the correct understanding of the principle of the function is also a certain degree of difficulty, so teachers in the teaching process to correctly grasp the teaching methods, summarize the difficulties in teaching, and teaching methods to reflect to help students better Understand quadratic functions. This paper first analyzes the goal of quadratic function teaching, secondly, it points out the key and difficult points, and in combination with specific examples, how to help students understand the quadratic function.
