一、教材分析“瞬时变化率——导数”一课是苏教版选修2-1中导数的第二课.新教材和以前的教材相比,导数这一章在过去内容上有所删减,不再系统地讲述极限的概念,而且在要求和侧重点上有所调整.本节课是在理解了平均变化率的基础上过渡过来的,为进一步学习函数的单调性、极值、曲线的切线做知识和方法的准备.二、学生分析学生为高二理科班学生,基础较好,有一定的自主学习能力.学生在物理中已经学习
First, the textbook analysis “instantaneous rate of change - derivative ” a lesson is the second lesson of the Jiangsu Education Edition elective 2-1 derivative of the new textbook compared with the previous textbook, the derivative of this chapter in the past, there is something Delete, no longer systematically about the concept of limit, but also in the requirements and focus on the adjustment.This lesson is based on the understanding of the average rate of change over the transition, in order to further study the monotonicity of the function, extreme , Tangential curve to do the knowledge and methods of preparation.Second, students analysis Students as sophomore science students, based on good, have a certain degree of independent learning ability.Students in physics have been learning
