化学是一门以实验为基础的自然学科,化学课程、教材、教法改革的重点之一,应该是化学实验的改革。过去研究实验改革,其重点是根据教材中知识点及其认知水平的需要,对某个实验进行改革或创新,使其简便易行,现象明显,操作安全;或是根据教学目标的要求,对实验教学方法提出改进意见,例如将演示实验改进为边讲边实验,将验证性实验改进为探索性实验。无疑,这些研究是必要的,今后仍将需要这方面的改革。
Chemistry is an experiment-based natural science. One of the focuses of chemistry curriculum, textbook and teaching reform should be the reform of chemical experiments. In the past, research and experiment reform focused on reforming or innovating an experiment according to the knowledge points in the textbooks and their cognition level, making it simple and easy to operate with obvious phenomena and safe operation. Or according to the teaching objectives, Improve the experimental teaching methods, for example, to improve the demonstration experiment to talk about the edge of the experiment, the verification experiment for the exploratory experiment. Undoubtedly, these studies are necessary and will still require reforms in this area.
