实验是物理教学中的重要方法和手段。加强实验教学,不仅可以增强物理教学效果,还可以培养学生的实验意识与品质,有助于提高学生创造性的学习能力。光的反射定律、光的折射定律都是通过实验推导出来的,具有很强的客观性,由于学生的经历和常识限制,对这两个定律的内容不可能一听就懂。所以,教师的演示实验就起了帮助他们发现规律、掌握规律、理解知识的非常重要的桥梁作用。所以,教师在做演示实验时,必须把光的反射、
Experiment is an important method and means in physics teaching. Strengthening experimental teaching can not only enhance the effectiveness of physics teaching, but also cultivate students ’experimental awareness and quality, and help to improve students’ creative learning ability. The laws of light reflection and light refraction are all deduced through experiments. They have strong objectivity. Due to the students’ experience and common sense, it is impossible to understand the contents of these two laws. Therefore, the teacher’s demonstration experiment plays a very important bridge role in helping them discover the law, master the law and understand the knowledge. Therefore, when teachers are doing demonstration experiments, they must reflect the light,
