实验在物理教学中的重要地位是人所共知的。改革实验教学的一个重要方面是针对传统实验的弊端,由教师和在教师指导下由学生设计新的实验方案。 (一)对传统实验进行改进有些传统实验效果不甚理想,有些因限于某些学校实验条件而无法进行。因此,教学中不宜完全照搬课本上的实验方案。探索新的实验方法无疑是一项创造性劳动。我们在探索新的实验方法上,一般按着“问题——设想——设计——实验——改进”
The important position of the experiment in physics teaching is known to all. One of the important aspects of reforming experimental teaching is to address the drawbacks of traditional experiments. A new experimental program is designed by the teacher and under the guidance of the teacher. (I) Improvement of Traditional Experiments Some traditional experiments have not been very effective, and some have been limited to certain school experimental conditions. Therefore, it is not advisable to completely copy the experimental program in textbooks. Exploring new experimental methods is undoubtedly a creative task. We generally follow the “problem-assumption-design-experiment-improvement” approach in exploring new experimental methods.
