让生活走入化学—《空气》教学策略

Make Life Into Chemistry— "Air" Teaching Strategies

这是关于初中化学《空气》一课的教学策略的探究与实践。空气成分的得出是建立在气压变化而导致的结果的基础上,而恰恰物理课上有关气压的知识只是简单了解,为了在化学课上说清楚物理知识,通过将学生熟悉的生活经验搬到化学课堂上的教学策略来突破难点,并获得良好的教学效果。

This is the research and Practice on the ＂ air＂ lesson junior high school chemistry teaching strate- gies. It is concluded that the air component is based on the pressure change on the results, but the physics class re- lated knowledge is a simple understanding of pressure,in order to explain physics knowledge in chemistry class, the students are familiar with the life experience to chemistry classroom teaching strategies to break through the difficul- ties, and get good teaching effect.
