要打好仗,必须有严谨周密的作战计刘。同样,教师要讲好课,必须首先备好课。用数学语言描述,就是:备好课是讲好课的必要条件。这里的必要条件包括两层意思:(1)要讲好课,一定要备好课;(2)没有备好课,肯定讲不好课。那么,怎样才能备好课呢?我们是这样做的:第一步,通读教材,期末,通读下学期所用教材的全部内容,以便对教材有个轮廓的了解,随即制定下学期的授课计划。第二步,精读教材,即按章精读教材,明确本章的教学目的要求、重点和难点所在,钻研其中的重要概念和基础知识,掌握它们在全章中的地位、作用和相互之间的联系,以便刘全章的内容做到心中有数。第三步是最关键的,也 To fight a good battle, we must have a rigorous and rigorous combat plan. Similarly, teachers should be good at class, we must first prepare the class. Described in mathematical language, is: prepare a good lesson is a necessary condition for a good lesson. The necessary conditions here include two meanings: (1) to have a good class, we must prepare the class; (2) did not prepare the class, certainly not good class. So, how can we prepare the lesson well? Here’s how we do it: The first step is to read through the teaching materials and at the end, read through the whole text of the teaching materials used in the next semester in order to get a basic understanding of the teaching materials and then to set the teaching plans for the next semester. The second step, intensive reading materials, that chapter by chapter intensive reading materials, a clear chapter of teaching objectives and requirements, priorities and difficulties where, study the important concepts and basic knowledge, grasp their position in the whole chapter, role and mutual relations , So that the content of Liu Quan Zhang do know well. The third step is the most crucial, too
