摘要
在初中化学实验教学中,由于有些实验易燃易爆、易对人体产生伤害等,导致实验难以用真实实验展开,本文以一氧化碳的性质为例,通过采用NOBOOK虚拟实验,并以对比教学法进行教学设计,将虚拟实验应用到实际课堂教学中,通过学生上台进行虚拟实验操作以及操作不当带来的不良现象,重复实验后加深学生对实验的印象,更好的理解实验,提升实验的视觉感与教学效果。
In junior high school chemical experiment teaching,because some experiments are flammable and explosive,and easy to cause harm to human body,it is difficult to use real experiments to carry out experiments.Taking the nature of carbon monoxide as an example,this paper applies virtual experiments to actual classroom teaching by using NOBOOK virtual experiments and comparative teaching method to design teaching.Through the students taking the stage to carry out the virtual experiment operation and the bad phenomenon caused by improper operation,students'impression of the experiments will be deepened after repeating the experiment,the experiments will be better understood,and the visual sense and teaching effect of the experiments will be improved.
