化学实验过程中往往产生很多异常现象,如何对待实验过程中出现的异常现象?如何在课堂上巧用这些异常现象呢?它是所有化学教师需要思考的问题。往往在意外中蕴含着正常,关键是透过表象看到本质。积极引导并给予合理的分析解释,就能化慌乱为沉着、化意外为平常,反而能因化腐朽为神奇的“意外”给学生留下更深刻的记忆,培养学生的探究和创新能力也就能轻易实现,使师生双方在探索活动中互相得到提高。
Chemical experiments often produce a lot of anomalies, how to deal with the anomalies that occur during the experiment? How to use these anomalies in the classroom? It is all chemistry teachers need to think about. Often contained in the accident is normal, the key is to see through the appearance of the essence. Actively guide and give a reasonable analysis and explanation, we can panic as calm, the accident as usual, but because of the decadent magical “Accident ” to the students left a deeper memory, develop students’ ability of inquiry and innovation It can easily be achieved so that both teachers and students can enhance each other’s exploration activities.
