物理演示实验设计的原则是,现象明显、激发学生兴趣;设置冲突、体现互动;结构简单、主题突出;取材方便、操作简便;效果明显、可见度高;操作规范、成功率高;设计合理、真实科学。在物理教学中应用演示实验设计原则,能有效地创设物理学习环境,培养学生的观察能力,激发其学习兴趣。 The principle of the physical demonstration experiment design is that the phenomenon is obvious, which arouses students' interest; sets the conflict and reflects the interaction; the structure is simple and the subject is prominent; the material is convenient and easy to operate; the effect is obvious and the visibility is high; science. The application of demonstration experiment design principles in physics teaching can effectively create a physical learning environment, develop students' observation skills and stimulate their interest in learning.
