化学实验是化学科学的基础,化学教学向来都十分重视化学实验的教学,本轮教育改革更是专门设置了“实验化学”模块,是唯一独立设置的实验课程。实验课程是对传统化学实验教学观念和方式的洗礼。下面仅以新课标《实验化学》教材实验3.1为例来谈谈如何搞好实验教学。按照教材要求,提供含有 Fe~(3+)、Al~(3+)、Ag~+、Ba~(2+)中三种或
Chemical experiments are the basis of chemical science. Chemistry teaching has always attached great importance to the teaching of chemistry experiments. This round of educational reform is specifically to set up an “experimental chemistry” module, and is the only experimental course set independently. The experimental course is a baptism of traditional chemistry experiment teaching concepts and methods. In the following, only the new curriculum standard “Experimental Chemistry” textbook experiment 3.1 will be used as an example to talk about how to do a good job in experimental teaching. According to the requirements of the textbook, three kinds of materials including Fe 3+, Al 3+, Ag 2+, and Ba 2 + are provided.
