要把一门课教好,关键问题在于不断地对教材进行取舍和增减的研究。时代在不断地前进,科学在不断地发展。目前,中学化学有了较大幅度的提高;有些内容,原来是在大学里讲授的,也编入了中学教材。再看国外大学一年级化学以及国内最近所编的理科一年级用的化学教材,内容极为丰富,并介绍了若干较深的近代理论。因此,我们对工科用的化学教材,也应该刻不容缓地研究其更新的问题。
To teach a course, the key issue is to continually study the choice of materials and increase or decrease. The times are constantly moving forward, science is constantly evolving. At present, secondary school chemistry has been greatly improved; some content, originally taught in the university, but also incorporated into the secondary school textbooks. Look at the first-year foreign university chemistry as well as the recent domestic first-year science textbooks, content is extremely rich, and introduced a number of deeper modern theory. Therefore, we should also study the chemical teaching materials used in engineering for updating without any delay.
