二次函数这部分知识出现在初中代数第四册的篇末。它在初中教材中占有相当重要的地位和作用。教师如何在教学中,发挥其核心和纽带的意义,期能达到从数形结合上,沟通代数、三角、几何各学科相互关系从而培养学生不断提高分析问题解决问题的能力,是教师在教学中应当引起十分注意的问题。下面,浅谈关于二次函数教学的几点尝试。 This part of the quadratic function appears in the end of the fourth volume of junior high school algebra. It occupies a very important position and role in junior high school textbooks. How teachers can exert their core and ties in teaching can reach the combination of numbers and forms, and communicate the interrelationships of algebra, triangles, and geometry to cultivate students’ ability to continuously improve their analytical problems and solve problems. Should pay great attention to the problem. Below, we will talk about several attempts on quadratic function teaching.
