含参数的二次函数最值问题是中学数学的重要内容,也是难点之一。这一问题初中和高中都有涉及,是初高中数学衔接的重要知识点之一。因此本文针对初中的课堂教学,利用GeoGebra软件搭建一个探究的实验平台,优化此类问题的解决过程,结合图像的动态变化,为学生创造数形结合的情境,理解这一问题的数学本质,让这一知识点在初高中之间无缝衔接。一、问题分析这类问题学生的掌握应该包含四个方面:1、对
The quadratic function with the parameters of the most value problem is an important part of secondary mathematics, but also one of the difficulties. This issue is related to both junior and senior high schools. It is one of the important knowledge points for math convergence in junior and senior high schools. Therefore, this article aims at junior high school classroom teaching, using GeoGebra software to build a research platform to explore, to optimize the process of solving such problems, with the dynamic changes in images, to create a mathematical combination of the situation for the students to understand the mathematical nature of the problem, let This point of knowledge is seamlessly connected between high school and high school. First, the problem analysis Students grasp such issues should include four aspects: 1, right
