混凝沉淀实验教学内容优化研究

Study on the Optimization of Coagulating Sedimentation Experimental Teaching Content

摘要: 基于新工科建设，从培养学生的工程思维、批判性思维和团队协作能力出发，以水质工程学基础实验之一混凝沉淀实验为例，探讨了新工科背景下的实验教学内容优化。针对传统混凝沉淀实验存在的内容比较单一，方法单调，不利于对学生创新能力的培养等问题，采用正交实验开展设计型实验，结合过滤–消毒工艺开展综合型实验，利用新技术创新实验内容。实践表明，通过优化实验教学内容，开展设计型、综合型以及创新型实验，效果优良，有利于学生创新能力的培养和综合素质的提高。

Abstract: Based on the construction of new engineering, starting from cultivating students’ engineering thinking, critical thinking and teamwork ability, taking the coagulating sedimentation experiment, one of the basic experiments of water quality engineering, as an example, the optimization of experimental teaching content under the background of new engineering is discussed. In view of the problems existing in traditional coagulating sedimentation experiments that the content is relatively simple, the method is monotonous, and it is not conducive to the cultivation of students’ innovative ability, orthogonal experiments are used to carry out designed experiments, combined with filtration-disinfection technology to carry out comprehensive experiments, and using new technology to innovate experimental content. Practice shows that by optimizing the experimental teaching content and carrying out design-based, comprehensive and innovative new experiments, the effect is excellent, which is conducive to the cultivation of students’ innovative ability and the improvement of comprehensive quality.
