高中物理课本(甲种本)第二册第八章“电子电量的确定”一节,教材编写目的是: 1.推导法拉第恒量的物理意义. 2.指出确定电子电量的一种方法. 用教材中的语言推理法推导法拉第恒量,学生反映理解困难。学生在高二化学第五章已经学习了电解质溶液的导电知识,利用化学计算方法推导法拉第恒量的实质意义,教和学都较容易。叙述如下:
High school physics textbooks (A type of books) Chapter II Chapter “Electricity of the determination of ” section, the purpose of the preparation of teaching materials is: 1. Derivation of Faraday constant physical meaning. 2. Point out a way to determine the electronic power. Derivation of Faraday’s constants using the language’s reasoning method in the textbooks, the students reflected difficulty in understanding. Students in the fifth grade of chemistry have studied the conductivity of electrolyte solution, using chemical calculation methods to derive the real meaning of Faraday constants, teaching and learning are easier. The description is as follows:
