本文分析了高中化学实验改进与优化要遵循科学性、直观性、效益性、绿色性原则等,在此基础上从常规实验、实验教学手段、实验教学方法等几个方面提出改进与优化思考:改进与优化化学实验装置与实验药品,利用信息技术手段与开展微型化学实验,开展探究式实验、综合性实验、趣味性实验等。 This paper analyzes that the improvement and optimization of high school chemistry experiment should follow the principles of science, intuition, efficiency and greenness. On the basis of this, we put forward the improvement and optimization thinking from the aspects of routine experiment, experimental teaching method and experimental teaching method. Improve and optimize chemical experimental devices and experimental drugs, the use of information technology and micro-chemical experiments, to carry out exploratory experiments, comprehensive experiments, interesting experiments.
