化学是一门以实验为基础的学科。实验教学可以激发学生学习的兴趣,帮助学生形成概念,获得知识和技能,培养观察能力和实验能力,还有助于培养学生实事求是、严肃认真的科学态度和科学的学习方法。因此,教师不仅要做实验,更应改进实验教学、探索实验方法、完善实验理论。 Chemistry is an experiment-based discipline. Experimental teaching can stimulate students’ interest in learning, help students to form concepts, acquire knowledge and skills, develop observation skills and experimental skills, and help students develop realistic and serious scientific attitudes and scientific learning methods. Therefore, teachers should not only do experiments, but also improve experimental teaching, explore experimental methods and perfect experimental theory.
