化学实验教学是中学化学教学的基础和重要组成部分,实验教学活动包括教师的演示实验、学生的分组实验、实验习题以及课外化学科技活动等。其中又以课堂演示实验及分组实验更为重要,在这我想谈谈演示及分组实验的教学。 Chemistry experiment teaching is the basis and an important part of chemistry teaching in middle school. Experimental teaching activities include teacher demonstration experiment, students’ group experiment, experimental exercises and extracurricular chemical science and technology activities. Among them, it is even more important to demonstrate experiments and group experiments in class. Here I would like to talk about the teaching of demonstration and group experiments.
