对于一个化学教师,了解化学发展史会更深入地体会每一个定律,更有效地设计、指导每一个实验,使课堂教学具有趣味性、哲理性。在讲授普通化学原子结构与周期系一章时,需要向学生介绍的内容有波尔理论、波函数、原子轨道、几率密度、电子云等物质结构方面的知识,但是由于课时的限制,这些知识只能硬塞给学生,不能展开讲。如果化学教师详细地了解这部份内容的发展史,就会把课讲活。十九世纪末叶,物理学理论已相当完善,力学有牛顿力学体系,电磁、光学方面已有麦克思维尔方程组,热现象方面有热力学,这些理论构成了完整的学科体系,称为经典物理学。对于当时常见的物理现象、基本上能够很好的说明,然而在此同时,实验又发现了一些新的现象, For a chemistry teacher, understanding the history of chemical development will deepen the understanding of each law, design and guide each experiment more effectively, and make classroom teaching interesting and philosophical. When teaching a chapter on common atomic structure and period, you need to introduce students to Boolean theory, wave function, atomic orbit, probability density, electronic cloud and other material structure, but due to the limitation of class time, this knowledge Only hard to the students, can not start speaking. If the chemistry teacher knows in detail the history of the development of this section, he will talk about the lesson. At the end of the nineteenth century, the theory of physics has been quite well developed. The mechanics has Newtonian mechanics. There are already the Maxwell equations in electromagnetics and optics, and the thermodynamics in terms of thermal phenomena. These theories form a complete discipline system called classical physics . For the common physical phenomena at that time, basically can be a good description, but in the meantime, the experiment also found some new phenomena,
