中学化学教学大纲里明确地指出:“化学是一门以实验为根据的科学”。所以课本里规定的教师演示和学生实验,都是完成教学任务的重要组成部分。自从1952年秋季起,中央教育部先后指定了采用东北人民教育出版社和中央人民教育出版社编译的高初中化学课本以后,克服了课本的混乱现象;尤其是在内容方面充分地介绍了苏联的先进经验,以其中所列的一些演示实验来讲,使我们感觉到耳目一新。然而由于各地的条件不一致,以致对有些实验不能充分发挥演示的作用,从而影响了教育效果,这是很遗憾的。现在根据个人的体会,提出了几个演示实验,介绍一些操作经验,希望广大读者,加以指正。
High school chemistry syllabus clearly pointed out: “Chemistry is an experiment based science.” Therefore, the textbook provides teacher presentations and student experiments, are an important part of the completion of teaching tasks. Since the autumn of 1952, the Central Ministry of Education successively designated the High Middle School Chemistry Textbook compiled by the Northeast People’s Education Press and the Central People’s Education Press to overcome the confusion of textbooks. In particular, it fully introduced the contents of the Soviet Union Advanced experience, with some of the demonstration experiments listed here, makes us feel fresh and new. However, due to inconsistencies in various places, it is regrettable that some experiments will not give full play to the role of demonstration and thus affect the effectiveness of education. Now based on personal experience, put forward a few demonstration experiments, introduce some operational experience, hope that the majority of readers, to be corrected.
