在物理教学过程中 ,既能激发学习物理的兴趣 ,又能直接切入主题的捷径是围绕课堂教学核心所创设的演示实验。运用各种各样的、简单易行的小实验 ,有着重要的意义。这些小实验 ,教师可以在课堂上演示 ,学生也可以在学校、在家中动脑设计、动手实验。通过动脑、动手实践 ,能激发 In the process of physics teaching, a shortcut that can stimulate interest in learning physics and can directly enter the topic is a demonstration experiment created around the core of classroom instruction. Using a variety of simple experiments is of great significance. In these small experiments, teachers can demonstrate in the classroom, and students can also use their brains at home and school to design experiments. Through brain, hands-on practice, can stimulate
