习题课教学是物理教学的重要一环，解题实践是学生掌握知识、发展智能的重要手段．在初中物理教学中挑选一些有代表性的题目，引导学生利用所学的物理知识，通过不同角度，沿不同方向思维，找出解决问题的多种方法，对于鼓励学生的独创性，初步培养学生的求异思维能力很有好处 Practice class teaching is an important part of physics teaching. Problem-solving practice is an important means for students to master knowledge and develop intelligence. Select some representative topics in junior high school physics teaching, guide students to use the physics knowledge they learned, and think through different angles and in different directions to find out a variety of ways to solve problems. To encourage students’ originality, students are initially trained. Different thinking ability is very good
