高中物理教學除了注意教材的適當精簡和教學方法的改進外,指導學生做練習題也是物理教學中一個重要的環節。要使學生對所學的理論完全瞭解、懂得透澈,練習題的習作有相當的帮助。所以就課堂教學而言,做練習题就是實際與理論結合,因此指導學生做練習題是教師應該特別注意的。筆者曾從事高中物理教學連續達十四年,個人認為指導學生做練習題有幾 In addition to paying attention to the proper simplification of teaching materials and improvement of teaching methods, physics teaching in senior high schools guides the students to practice exercises, which is also an important link in physics teaching. To enable students to fully understand the theory of learning, know thoroughly, practice exercises are quite helpful. So in terms of classroom teaching, doing exercises is the combination of the actual and the theory, so instructing students to do exercises is a teacher should pay special attention. I have been engaged in high school physics teaching for up to fourteen years, personally think that guiding students to do exercises
