二次函数是现在初中数学的必学内容,也是中考的重点。它不但能让学生的思维能力得到彻底锻炼,而且也能激发学生的潜在能力。学好二次函数有很大意义,第一,能够为学生以后学习其他数学知识奠定基础,第二,又可以通过二次函数解决现实中的一些问题。笔者从事数学教育多年,仅以个人的经验来简单谈一下如何学好二次函数。二次函数在初中数学中所扮演的重要角色不言而喻,对很多学生来说,学好二次函数都具有一定的难度,因为
The quadratic function is now the subject of junior high school mathematics, and it is also the focus of the examination. Not only does it allow students to exercise their thinking skills thoroughly, but it also stimulates students’ potential abilities. Learning the quadratic function has great significance. First, it can lay a foundation for students to learn other mathematics knowledge. Second, they can solve some problems in reality through quadratic functions. I have been engaged in mathematics education for many years, and I only talked briefly about how to learn quadratic functions based on personal experience. The important role of the quadratic function in junior high school mathematics is self-evident. For many students, learning the quadratic function is difficult, because
