作者在两年前曾经写过「化学之基本观点」一文,登载在本刊第五卷第二期。因为作者就过去教学化学的经验与体会,觉得学生对于化学一科,大都以为繁复而须强记,感兴趣的少,感困难的多,所以提出了「阴阳和」、「强弱争」、「热力变」、「平衡成」四种基本观点,希望能使繁复趋于简化,强记变为了解,困难化为兴趣。作者过去在讲授普通化学时,常用这四种基本观点开端,以后随时引证,力求简化,并在有机会讨论中学化学教学法时,用来贡献于中等学校教师。抗战胜利以后,作者试编一本普通化学,除了 The author wrote “The Basic View of Chemistry” two years ago and is published in the second issue of Volume V of this issue. Because of the past experience and understanding of teaching chemistry, I feel that students are most likely to be complicated and need to be remembered for their interest in chemistry. They are less interested and have more difficulties. Therefore, they proposed “yin and yang,” “strength and weakness, ”Heat change“ and ”balance into" the four basic point of view, hoping to simplify the complexity of the complex, strong memory into understanding, difficulties into interest. In the past, he taught common chemistry and started with these four basic points of view. At any time, the author cites any attempt to simplify it and contributes to secondary school teachers when they have the opportunity to discuss chemistry teaching in middle school. After the victory of Anti-Japanese War, the author tried a normal chemistry, except
