在初中物理教学中,充分利用课本的例题和习题展开讨论,是使初中学生掌握知识和运用知识的有效途径。其中一条重要而有效的措施是对课本题目进行变式,有目的有层次的组成系列问题,使学生在处理的过程中,能够形成较好的知识体系,在这里,编好题目是关键,下面谈谈常见的三种类型。一、解法研究型一道习题常有多种解法,初中学生常常只是满足于得到一个结果,因而教学中要启发学生再多想一想,并且介绍一些解题的方法,让他们认识到一个物理现象或物理过 In the junior high school physics teaching, the full use of textbook examples and exercises to discuss, is an effective way for junior high school students to master knowledge and use of knowledge. One of the important and effective measures is to change the subject of the textbook, and purposefully and hierarchically form a series of questions so that students can form a better knowledge system in the process of processing. Here, it is the key to compile the topics. Talk about the three common types. First, the solution to a type of exercise is often a variety of solutions, junior high school students are often satisfied only to get a result, so the students should be inspired to think more in teaching, and introduce some methods to solve problems, so that they recognize a physical phenomenon Or physical
