一、教学地位二次函数探究题是中考的一个热点,也是一个重点,利用二次函数求最大利润问题是其中的典型代表,又是本章学习的一个难点,并且与一元二次方程有紧密的联系.二、教学过程1.明确目标,定主题上课前利用PPT出示了本堂课学习的目标:(1)从实际问题中寻找变量之间的二次函数关系,并应用函数的知识求出最大(或最小)值;(2)将实际问题转化为数学问题,体现数学的建模思想.
First, the teaching status of the secondary function to explore the question is a hot spot in the exam is also a key point, the use of quadratic functions for maximum profit is one of the typical representatives of this chapter is a difficult learning, and with the quadratic equation Contact 1. Second, the teaching process 1 clear objectives, set the theme Pre-class PPT use this lesson to show the objectives of learning: (1) from the actual problems in finding the quadratic function between variables, and the application of knowledge to find the maximum (Or minimum) value; (2) the actual problems into mathematical problems, reflecting mathematical modeling ideas.
