新课程标准中明确指出:“实验对于实现高中化学课程目标具有不可替代的作用。”新教材的编写十分重视实验在学习化学中的重要作用,注重精心设计实验方案,积极开发探究实验。如苏教版化学1(必修)“专题4第二单元生产生活中的含氮化合物”部分,通过喷泉实验来探究氨气的重要性质,达到了提高教学效果,培养学生的实验能力和学习兴趣的目的。如果敢于打破思维定势,设计多彩的烟雾“喷泉”辅助教学,不仅能
The new curriculum standard clearly states: “The experiment has an irreplaceable effect on achieving the goals of the high school chemistry curriculum.” “The preparation of the new teaching material places great emphasis on the important role of experiment in learning chemistry, pays great attention to elaborately designing experimental programs and actively developing research experiments. Such as the Sujiao version of Chemistry 1 (compulsory) ”Part 4 of the second unit of production of nitrogen compounds “ part of the fountain through the experiment to explore the important properties of ammonia to achieve the teaching effectiveness, to develop students experimental ability and The purpose of learning interest. If you dare to break the mindset, design colorful smoke ”fountain " aided teaching, not only
