形式逻辑又称普通逻辑,是研究思维的初步规律的逻辑学。在物理规律的教学中要重视基本的概念和基本的定律,但对物理概念和基本定律的认识是系统、全面,还是一知半解;是正确、深刻,还是错误、肤浅的,就必须以形式逻辑知识为指导。实际上,任何物理教师在教学中都不自觉的以逻辑的方式引导学生思维,从而使学生在思考和理解中获得知识。对形式逻辑的研究和理解是有助于避 Formal logic, also known as ordinary logic, is the logic of the initial law of thinking. In the teaching of physics, we should pay attention to the basic concepts and basic laws. However, the understanding of the concepts and basic laws of physics is systematic, comprehensive, or incompletely understood. Whether it is correct, profound, wrong or superficial, it must be based on formal logic As a guide. In fact, any physical teacher unconsciously guides students’ thinking in a logical way so that students acquire knowledge in thinking and understanding. The study and understanding of formal logic helps to avoid it
