摘要
作为化学知识的教授辅助手段,中学化学课堂的演示实验具备了良好的直观性以及示范性,而更为科学合理的课堂演示实验能够有效的促进教学、提升效率。探究了演示实验的分类、演示实验注意事项、演示实验认知等方面,为更好的发挥化学课堂演示实验的作用奠定基础。
As an assistant means of teaching chemistry knowledge,the demonstration experiment in the middle school chemistry classroom has good intuitiveness and demonstration,and the more scientific and reasonable classroom demonstration experiment can effectively promote teaching and improve efficiency.This paper explores the classification,precautions and cognition of demonstration experiments,which lays the foundation for better playing the role of chemical classroom demonstration experiments.
