循环实验模式的构建与教学实践

摘要

In accordance with the "5R" principle of the green chemistry concept and green chemistry experiment, two cycle experiment teaching modes were proposed, and practiced in the agricultural science foundation of chemistry experiment teaching. The results show that the implementation of circulation experiment teaching models can save experimental resources and reduce experimental cost while ensuring the quality of experiments teaching. It is beneficial to the recycle of experimental products and the green treatment of experimental waste. Moreover, it stimulates students' interests in chemistry experiments, strengthens the training of practical ability, and plays a very important role in establishing the concept of environmental protection.%按照绿色化学理念及绿色化学实验的“5R”原则,提出了两种循环实验教学模式,并在农科基础化学实验教学中进行了实践.结果表明:循环实验教学模式的实施,在保证教学质量的基础上节约了实验资源,降低了实验成本,有利于实验产物的再利用和实验废物的绿色化处理,并且在激发学生学习化学实验的兴趣、强化动手能力的训练、树立环保观念方面有非常重要的作用.
