著名化学家戴安邦先生指出 :“只传授知识技术的化学教育是片面的 ,全面的化学教育要求既传授化学知识和技能又训练科学方法和思维 ,还要培养科学精神和品德”。几年来 ,我尝试在学生实验的基础上补充一些相关的实验 ,力图使学生从不同侧面 ,用不同方法观察某一实验或从几个实? The famous chemist Mr. Dian Anbang pointed out: “The chemical education that only imparts knowledge and technology is one-sided. Comprehensive chemistry education requires the imparting of chemical knowledge and skills as well as the training of scientific methods and thinking, as well as the cultivation of scientific spirit and morality.” Over the past few years, I have tried to add some related experiments on the basis of student experiments, trying to make students observe the experiment or the reality from different perspectives.
