摘要
实验中的异常现象能引起学生的关注、激发学习兴趣,如果通过"异常实验设计"使实验异常现象常态化,即人为地有意地设计实验,使实验出现受设计者控制的但明显不合理的实验结果,让学生自主地认识到实验中不应出现的错误,进而用形象直观的方法使学生从"不合理"理解"合理",提高了教学效果。
Abnormal Phenomena in Experiment can Attract Attention from students, if Abnormal Phenomena in Experiment becomes Stablization, that is mean experiment is purposely designed to Generat obviously unreasonable but Controlled data, so students independently discover and explore questions, this improves teaching effects.
