众所周知,化学是一门以实验为基础的科学.再者,培养学生的能力主要有自学能力、思维能力、实际动手操作能力和创造力等,而这些能力的形成和发展,在化学教学中都是与实验密切相关的,因此化学教学改革必须突出加强实验教学. 一、以实验为先导,是化学自学的特殊要求. 化学中的许多概念、理论以及元素和化合物的知识,都是从实验导出或用实验加以验证的,有些化学知识与学生在实际生活中得到的直接经验有较大的距离.这正是学生在无实验的条件下进行化学自学的困难之
As we all know, chemistry is an experiment-based science. Furthermore, the ability to train students is mainly self-learning ability, thinking ability, practical hands-on ability and creativity, and the formation and development of these skills are all in chemistry teaching. It is closely related to the experiment. Therefore, the reform of chemistry teaching must emphasize the strengthening of experimental teaching. First, taking experiments as the guide is the special requirement of chemistry self-study. Many concepts, theories and knowledge of elements and compounds in chemistry are derived from experiments. Or experiments are used to verify that some chemical knowledge has a great distance from students’ direct experience in real life. This is precisely the difficulty of students doing chemical self-study under conditions without experimentation.
