我在长期的物理教学实践中感觉到,教材中一些传统的物理实验,实验原理虽然是正确的,但存在着实验效果不明显、成功率不高,或安全性差等问题。这些不足,有的看起来似乎事小,却长期影响着相关实验的教学。为了提高实验的教学效果,我针对这些实验所存在的不足之处进行了科学的分析和多次探索后发现,这些实验存在以上不足的主要原因,是因为这些实验在实验器材的选用上或实验方案的设计上还有不够科学之处所致。只要 I feel in the long-term practice of physics teaching that some traditional physics experiments in the textbooks are correct. The experimental principle is not obvious, the success rate is not high, or the safety is poor. These deficiencies, some may seem small, have long influenced the teaching of related experiments. In order to improve the teaching effect of experiments, I conducted a scientific analysis and repeated exploration for the deficiencies of these experiments and found that the main reason for the above shortcomings in these experiments is that these experiments are mainly based on experimental equipment selection or experiment The design of the program is not scientific enough. as long as
