习题是物理教学的一个重要组成部分,是课堂教学的补充与延伸,也是师生信心交流的一个窗口。如何利用现有习题,发挥其巨大作用,培养学生的思维能力呢?下面就教学实践中“一题多变”的习题教学谈几点认识。一、培养学生思维的广阔性习题教学中要选择典型题目。许多物理题,与实际联系密切,都可以实现“一题多变”。在教学中,对一些习题,要求学生解完后,再思考如何增减条件使其变成相关的习题。例1:在讲中考模拟卷习题“一个人用100N的力,沿水平方向匀速推着
Exercises are an important part of physics teaching, complementing and extending classroom teaching, and also a window of confidence exchange between teachers and students. How to use the existing exercises to play its tremendous role in developing students’ thinking ability? Here on the teaching practice ”a question “ First, to develop a broad range of student thinking exercises to choose a typical topic of teaching. Many physical problems, with close contact with the actual, can be achieved ”a question changeable “. In teaching, for some exercises, students are asked to finish, and then consider how to change the conditions to make it a related exercise. Example 1: In the test simulation test exercise ”a person with a force of 100N, pushed horizontally along the uniform
