物理是一门以观察和实验为基础的自然科学,物理规律都是在观察和实验的基础上认真总结和思考得来的。实验教学既是物理知识教学的基础,也是物理课堂教学中创新教育的一种主要渠道和有效手段。著名物理学家杨振宁也曾对中、美两国学生进行一番比较后指出:“中国的学生学习非常刻苦,基础知识丰富、扎实,且 Physics is a natural science based on observation and experiment. The laws of physics are carefully summarized and thought-provoking on the basis of observation and experiment. Experimental teaching is not only the basis of physical knowledge teaching, but also a major channel and effective means of innovative education in physics classroom teaching. Well-known physicist Yang Zhenning also made some comparisons between Chinese and American students after he pointed out: ”Chinese students learn very hard, they have rich basic knowledge and are solid
