在高中理科的各学科中,物理相对来说是较难的一科。学过高中物理的大部分学生,特别是物理成绩中等的学生,总会有这样的疑惑,“上课都能听懂,但是在自己独立解题时就不会了”。所以如何上好习题课,让习题课成为学生掌握方法,形成技能,提升能力的最佳途径,是我们老师应该好好研究的问题。一、精心选题一道好题目应该有一定的容量,对知识有一定的整合。但从解题方法上看却要有基础性。所以老师在选题时要慎重,必要时要自编题目,将一道题目进行分解,铺设台阶层层递进,或者将题目进行整合,纵横交错。如调换已知条件和未知量的角色,让题目具有技巧性、灵活性,但方法却要以基
Among the subjects of high school science, physics is a relatively difficult subject. Most students who have studied high school physics, especially those with medium grades, will always have such doubts, “Class can understand but will not do it when they solve their problems independently.” Therefore, how to make a good exercise class and make the exercise class the best way for the students to master the methods, form the skills and improve their abilities are the problems our teachers should study well. A well-selected topic A good topic should have a certain capacity, knowledge of a certain degree of integration. However, there is a fundamental way to solve the problem. Therefore, the teacher should be careful when selecting the topic, if necessary, to make their own questions, a topic will be decomposed, laying step by step or progressive, or subject integration, criss-cross. Such as the exchange of known conditions and the role of unknown amount, so that the topic is skillful and flexible, but the method has to base
