我校是一所县重点高级中学,生源较好.然而总有较多学生进入高中之后,不能适应高中阶段的数学学习,在思维要求上有较大差距,成绩明显下降趋势.特别是在函数这方面.下面就二次函数的学习谈几点看法.在初中教材中,对二次函数作了较简单的研究,由于初中学生基础薄弱,又受其接受能力的限制,这部份内容的学习多是机械的,很难从本质上加以理解.进入高中以后,尤其是高三复习阶段,要对他们的基本概念和基本性质(图象以及单调性、奇偶性、有界 Our school is a county key high school, students better .But there are always more students into high school, can not adapt to high school mathematics learning, there is a big gap in the thinking requirements, the performance decreased significantly.Especially in the function Here to talk about the quadratic function of learning to talk about a few points in the junior high school textbooks, the quadratic function made a simple study, due to the weak foundation of junior high school students, but also by their ability to accept this part of the content Learning is mechanical, it is difficult to understand in essence.After entering high school, especially during the third year of high school review, to their basic concepts and basic properties (image and monotony, parity, bounded
