实验工作要加强现在我国的教育工作已经开始走上了正轨,学校里和社会上的学习风气很浓。但是,实验工作还没有很好开展起来。许多中学生没有做过实验,不少大学生也没有受到必要的实验训练,这说明人们对实验工作的认识不足。早在前清时期,受张之洞“中学为主,西学为用”的影响,有些小学除自然外,也开始学习生物、化学和物理,并且有了演示实验。1907年,我在天津民立第二小学高小二年级上化学课时,化学老师每堂课都作演示实验。从玻璃仪器的安装到氢气、二氧化硫、氨、氯气、硫酸等的制备,一年内作了三、四十个化学物质的制备,性能和应用的演示实验。在 Experimental work to be strengthened Now that our country’s education work has begun to go on track, there is a strong learning atmosphere in schools and in society. However, the experimental work has not been well developed. Many high school students did not do experiments, many college students have not been the necessary experimental training, indicating that people lack of understanding of experimental work. As early as the Qing dynasty, influenced by Zhang Zhidong’s “middle school-based, western-learning” use, some primary schools began to study biology, chemistry and physics in addition to nature and had demonstration experiments. In 1907, I was in Tianjin Minli Primary School sophomore year on the chemistry class, the chemistry teacher every demonstration for experiments. From the installation of glassware to the preparation of hydrogen, sulfur dioxide, ammonia, chlorine gas and sulfuric acid, three to forty demonstration experiments on the preparation, performance and application of chemical substances were made in one year. in
