一、课堂再现非常有幸,笔者参加了常州市中青年化学教师优质课评比活动,课题是《水的组成》.我把这节课的教学目标确定为:通过电解水实验,认识水的组成,学习对实验现象的观察、分析,体会科学研究的思维方法;通过阅读“水的组成揭秘”小故事,使学生感受到敢于怀疑和实事求是的科学态度在科学研究中的重要性.
First, the classroom reproduction is very fortunate, I participated in Changzhou City, young and middle-aged chemistry teacher quality class competitions, the subject is “water composition.” I set the teaching objectives of this lesson as: through the electrolysis of water experiments, understanding of the composition of water, Learn the observation of experimental phenomena, analysis, experience the scientific method of thinking; Through the reading “The composition of the water reveals ” a small story, so that students feel the scientific attitude of daring to doubt and seek truth from facts in the scientific research of importance.
