实验是物理教学的一个重要组成部分。中学物理教学大纲指出:“大纲中规定的实验,都应该力求做到。如果限于条件,一时做不到的,可以用类似的实验代替。条件较好的学校,还可以多做一些。”因此,不管哪类学校的教师,都应该根据教学的实际需要,从教材的内容出发,自己设计一些实验并制作一些仪器,以弥补当前实验器材的不足,改变物理教学中普遍存在的重习题、轻实验的畸形状态,使物理教学质量更扎实地提高一步。下面就我们在设计实验与自制仪器的实践中遇到的问题,提出一些需要注意的原则,供老师们参考。
Experiments are an important part of physics teaching. The syllabus for secondary school physics points out: “The experiments stipulated in the syllabus should strive to be done. If you limit the conditions, you can’t replace them with a similar experiment. If you have a better school, you can do more.” Regardless of what kind of school teachers, according to the actual needs of teaching, starting from the content of teaching materials, designing some experiments and making some instruments by themselves, to make up for the lack of current experimental equipment, to change the common problems in physics teaching, and light The deformed state of the experiment has improved the quality of physics teaching more solidly. Here are some problems that we need to pay attention to when designing experiments and self-made instruments.
