化学是一门以实验为基础的自然科学,实验是化学教学中发展学生科学素养不可或缺的重要途径,具有其他教学手段无法代替的特殊重要作用。在化学教学中,许多化学概念、原理、规律的引入都是从实验探究展开并最终由实验加以论证的,实验教学不仅可以使学生获得知识和技能,激发学生的学习兴趣,引发探究的动机和行为,而且有利于对学生进行科学方法的训练,培养 Chemistry is an experiment-based natural science. Experiment is an indispensable way to develop students’ scientific literacy in chemistry teaching. It has the special and important role that other teaching methods can not replace. In chemical teaching, many chemical concepts, principles and laws are introduced from the experimental exploration and finally demonstrated by experiments. Experimental teaching can not only enable students to acquire knowledge and skills, stimulate students’ interest in learning, motivate the exploration and Behavior, but also conducive to students in scientific methods of training and training
