化学是一门以实验为基础的自然科学,新课改要求以科学探究为突破口,以教师角色、教学方式、学习方式的转变为落脚点,使学生的创新能力、探究能力得到发展。实验可以增强启发性、探究性和趣味性,从而提高课堂教学效果,实验是学好化学的金钥匙。 Chemistry is an experiment-based natural science. The new curriculum reform requires that scientific inquiry should be taken as a breakthrough to change the role of teachers, teaching methods and learning methods into a foothold so as to enable students to develop their innovative and exploratory skills. Experiments can enhance enlightenment, inquiry and fun, so as to improve the effectiveness of classroom teaching. Experiment is the golden key to learning chemistry well.
