基于Jigsaw教学法的环境学科实验教学实践

Practice on experimental teaching for environment discipline based on Jigsaw teaching method

以污水处理厂剩余污泥厌氧消化工艺改善为背景,设计了热处理、碱处理和热碱联用对剩余污泥减量化的实验。实验教学形式采用Jigsaw合作式学习模式,使其融于实验理论及背景学习、实验内容设计以及实验结果讨论的环节中,通过增强学生的参与度和师生互动,激发了学生的学习兴趣,巩固了学生的理论知识和操作技能,提升了学生的自学能力、协作能力和研究能力。

Based on the improvement of the anaerobic digestion process of the excess sludge in a sewage treatment plant,the experiment of the excess sludge reduction is designed by the heat treatment,alkali treatment and heat and alkali combined treatment.The Jigsaw cooperative learning mode is adopted for the experimental teaching so that it is integrated into the links of the experimental theory,background learning,design of experimental content and discussion of experimental results.By enhancing students’participation and interaction between teachers and students,the students’interest in learning is stimulated,their theoretical knowledge and operational skills are consolidated,and their self-learning ability,cooperation ability and research ability are promoted.
