习题教学是中学物理教学的一个重要组成部分。但在教学中我们往往仅注重题目的解答过程和结果,而忽视了题目对学生学习的引导作用。这是物理教学中的一个疏忽。不论采用何种形式进行习题教学,目的主要是:①巩固和加深对有关物理概念和规律的理解;②掌握解题的方法和技巧;③培养物理思维能力。因此,我们进行习题教学并非单是为了解决问题本身,更重要的是掌握隐含于问题之中的概念和规律,问题之外的思路和方法。而要达到此目的,关键在善于引导。
Exercise teaching is an important part of physics teaching in middle school. However, in teaching, we often focus only on the problem-solving process and results, while ignoring the guiding role of the topic on student learning. This is an oversight in physics teaching. Regardless of the form of exercise, the purpose is mainly to: 1 consolidate and deepen the understanding of the relevant physical concepts and laws; 2 master methods and techniques to solve problems; 3 develop physical thinking ability. Therefore, we do exercise teaching not only to solve the problem itself, more importantly, to grasp the concepts and laws implied in the problem, and the ideas and methods beyond the problem. To achieve this goal, the key is to be good at guiding.
