化学是一门以实验为基础的学科,化学实验可以分为演示实验、随堂实验、学生实验三大类,在化学教学中起着十分重要的作用。实验不仅可帮助学生形成化学基本概念,理解和巩固化学知识,还能培养学生观察现象、分析问题、解决问题的能力,养成实事求是、严肃认真的科学思维方法。一、化学教学中的演示实验化学教学中的演示实验在探索化学知识、示范操作规则、激发学生兴趣、培养学生创新能力等方面的作用是不言而喻 Chemistry is an experiment-based discipline. Chemistry experiments can be divided into demonstration experiments, quasi-experiments, and student experiments. They play a very important role in chemistry teaching. The experiment can not only help students to form the basic concepts of chemistry, understand and consolidate the knowledge of chemistry, but also cultivate students’ abilities of observing phenomena, analyzing problems and solving problems, and developing practical and serious scientific thinking methods. A demonstration experiment in chemistry teaching Demonstration experiment in chemistry teaching is self-evident in exploring chemical knowledge, demonstrating rules of operation, arousing students ’interest and cultivating students’ innovative abilities
