物理学科是一门实验与理论相结合的学科。在物理学科的教学过程中,实验可以把抽象的概念、知识转化为具体的实验现象。让学生更简单地理解物理知识,并且能提高学生的学习兴趣。而面对农村中学的现状,要想完全展开实验教学还是困难颇多。主要原因是农村中学现在整体人数在减少,所带来的资金投入也减少,而实验室的器材却很陈旧。有的学校用的还是几年甚至十年前的器材,而与之教学的教材几乎每年都有一些变化,带来的问题就是现有的实验器材没法再现教材中的实验,如果每年都购买器材这样的操作又没法进行。所以农村物理教师要想上好一节实验课就得多动心思,创造条件上好。这个时候花心思对一些实验进行改进就显得尤为重要。 Physics is a combination of experiment and theory. In the course of physics teaching, experiments can abstract concepts and knowledge into concrete experimental phenomena. Enable students to more easily understand the physical knowledge, and can improve students’ interest in learning. In the face of the status quo in rural middle schools, it is still more difficult to fully launch experimental teaching. The main reason is that the overall number of rural middle schools is declining now, the capital investment brought about by it is also reduced, and the laboratory equipment is very old. Some schools still use a few years or even ten years ago, equipment, and teaching materials with some changes every year, the problem is that the existing experimental equipment can not reproduce the textbook experiment, if the annual purchase Equipment such operations can not be carried out. Therefore, rural physics teachers want to take a good experimental class, we must move more to create conditions better. This time to spend some time to improve the experimental study is particularly important.
