一、学习目标1.进一步体会运动变化过程中的数量变化;2.从描述变量之间对应关系的角度刻画一般函数的基本特征,初步建立函数的概念.二、学习重点概括并理解函数概念中的单值对应关系.三、教学过程设计(一)创设情景,复习导入.问题1汽车以60千米/时的速度匀速行驶,行驶里程为s千米,行驶时间为t小时.(1)先填表,再试用t的式子表示s;(2)事件中有几个数值是发生改变的量?有几个
I. Learning Objectives 1. To further understand the changes in the number of changes in the process of movement 2. To characterize the basic features of general functions from the perspective of describing the correspondence between variables and to establish the concept of functions initially 2. To focus on learning and to understand function concepts (1) to create a scenario, review import.Question 1 car at 60 km / h speed uniform speed, mileage is s km, driving time is t hours. (1) First fill in the form, and then try to use the formula t said s; (2) the event of a few changes in the value of the number?
