众所周知,物理教学离不开实验。物理课本中的概念、原理、规律、定律等知识都是在观察实验的基础上或经过实验验证的情况下得出的。物理是以实验为提前和基础的学科,实验是物理学的本质属性,它反映了知识的物理性。学习、领会和牢固掌握物理知识,学以致用,就必须高度重视物理知识的实验教学作用。但在农村初中,物理教学不重视实验或某些实验不做或方法不当的现象较为普遍,这是影响农村物理教学质量大 As we all know, physics teaching can not do without experiment. The concept, principle, law, law and other knowledge in the physics textbook are all based on the observation experiment or the experimental verification. Physics is based on experiments in advance and based on discipline, experiment is the essential attribute of physics, which reflects the physicality of knowledge. To learn, understand and firmly grasp the physical knowledge, learn from practice, we must attach great importance to the role of experimental teaching of physical knowledge. However, in rural junior high schools, physics teaching does not attach importance to the experiment or some experiments do not do or improper method is more common, which is affecting the quality of rural physics teaching
