高三数学复习常会安排章节“收尾”课,帮助学生系统回顾和展望该章节的知识内容,归纳和提炼重点题型的解题方法,渗透和挖掘常规的数学思想方法.这种课型不同于新授复习课也不同于常规的习题课.下面以“导数的意义和应用”为例,交流笔者的一些思考和做法,希望同行们不吝赐教.第一部分课堂实录1.1创设问题情境、初步构建核心知识的思维导图师:前面我们复习了函数一章,请同学们回忆:导数的意义是什么?(问题1)
Senior high school mathematics review often arrange chapters “ending ” class to help students systematically review and forecast the knowledge content of this chapter, induction and refine key problem-solving methods, infiltration and mining of conventional mathematical thinking method. In the new grant classes are also different from the conventional exercises class. Here to “Derivatives meaning and application ” as an example, to exchange some of my thoughts and practices, I hope my colleagues have educated us.The first part of the class record 1.1 to create problem situations, Initially build the core knowledge of the mind Mapping Director: In front of the chapter we reviewed the function, please classmates memories: What is the meaning of the derivative?
