二次函数是初中数学教学的难点与重点,如何提高二次函数教学效率,使学生熟练掌握二次函数相关题型的解答思路及方法,提高初中生综合数学能力是任课教师关注的重点.一、提高二次函数认识相对于初中数学其他知识而言,二次函数研究的是自变量与因变量之间的关系,比较抽象,学生理解难度大.研究发现,部分学生不注重二次函数基础概念的学习与理解,因此,解答二次函数相关题目时常常出现一些不该出现的问题.因此,初 The quadratic function is the difficulty and focus of junior high school mathematics teaching. How to improve the teaching efficiency of quadratic function, make students master the train of thought and method of quadratic function related questions and how to improve the comprehensive mathematics ability of junior high school students are the key points that teachers should pay attention to. , Improve the awareness of quadratic function Relative to junior high school mathematics other knowledge, quadratic function study is the relationship between independent variables and dependent variables, more abstract, difficult for students to understand.Study found that some students do not pay attention to the basis of quadratic function Concept of learning and understanding, therefore, to solve quadratic function related topics often appear some problems that should not occur. Therefore, the beginning
