教学是一门科学。课堂教学是教学的基本形式。物理课的课堂教学既要把间接知识传授给学生,还要交给学生掌握知识的途径和能力。因此课堂教学必须符合辩证的认识规律,才能让学生主动地、循序渐进地掌握知识,同时也培养了学生科学的思维方法。我认为,认识规律首先表现在人类对总的知识的认识规律,也就是科学发展史,其次是学生掌握知识的认识规律。下面谈谈在物理课上浅谈科学发展史的体会。科学发展史本身是符合“实践——认识——实践”这一辩证规律的。近代、现代的科学如电学、光学、原子物理等,更生动地说明了这一点。因此在备课中,必须将具体的知识纳入这一系统中去,掌握这些知识的内在联系,在讲授时,就能从某一观察到的 Teaching is a science. Classroom teaching is the basic form of teaching. Physics class classroom teaching should not only impart indirect knowledge to students, but also to students to master the ways and capabilities of knowledge. Therefore, classroom teaching must conform to the dialectical understanding of rules, in order to enable students to take the initiative, step by step to acquire knowledge, but also cultivate students’ scientific thinking. In my opinion, the law of cognition is first manifested in the human understanding of the general law of knowledge, that is, the history of scientific development, followed by students grasp the law of knowledge. Let’s talk about the experience in physics class on the history of scientific development. The history of scientific development itself conforms to the dialectical law of “practice - cognition - practice”. Modern, modern science such as electricity, optics, atomic physics, etc., more vividly illustrates this point. Therefore, in lesson preparation, we must incorporate specific knowledge into this system to grasp the intrinsic connection of these knowledge, and from the perspective of teaching
