摘　　要：通过开展污水中COD测定的开放实验,探索任务驱动的实验模式对学生综合素质提高的效果。一共开展三个班次两个学期的试验项目,通过平行和前后对比,发现合理地设置实验任务,能够更好地调动学生的实验积极性。此外,基于科研调查的试验项目,对于学生的积极性、主动性和团队协作能力都有很好的锻炼作用。具体实施过程中也发现了一些问题,并在后期实施中进行了针对性的调整。By developing opening experiment of COD determination in sewage, the effects of task-driven experimentmode on the improvement of students＇ comprehensive quality were explored. A total of three courses were carried out fortwo semesters. Through the parallel and before and after comparison, it was turned out that reasonable setting up of theexperimental task can better motivate the students＇ experimental enthusiasm. In addition, based on the research project,the students＇ enthusiasm, initiative and teamwork were well exercised. Some problems were found in the implementationprocess and the corresponding adjustment was made in the later implementation.
