化学实验是化学学科的基础,也是化学课堂教学的重要组成部分,教师应该意识到在分组实验中,学生是实验舞台的主人。通过分组实验不但可以对学生化学概念的形成、知识的理解和巩固起到帮助作用,还可以培养学生的实验能力并掌握实验基本操作,更重要的是可以培养学生实事求是、严肃认真的科学态度、科学方法和开拓创新的精神。教学是一门艺术,实验教学中的 Chemistry experiments are the basis of chemistry and are also an important part of chemistry classroom teaching. Teachers should be aware that in group experiments, students are the masters of the experimental stage. Group experiments not only can help students understand the formation of chemistry concepts and consolidate knowledge, but also cultivate students’ experimental abilities and master the basic operation of experiments. More importantly, they can cultivate students with realistic and serious scientific attitudes, Scientific method and pioneering and innovative spirit. Teaching is an art, experimental teaching
