实践表明,二次函数是中学数学教学和学习中较困难的知识点之一。然而,二次函数作为一种基本的函数类型,在学习中又显得非常重要,也是初高中教学中联系较密切的内容。高中阶段,二次函数主要渗透在其他学习内容中,如不等式、数列、平面解析几何等。在实际教学中发现,对二次函数有关内容的学习,学生很难把握初中与高中的衔
Practice shows that the quadratic function is one of the more difficult points in middle school mathematics teaching and learning. However, as a basic function type, quadratic function is very important in learning and it is also the content that is closely related to the teaching of junior high school. In high school, the quadratic functions mainly permeate other learning contents, such as inequalities, series, plane analysis geometry, and so on. In the actual teaching found that the content of the quadratic function of learning, students are difficult to grasp the title of junior high school and high school
