摘　　要：新工科背景下的复合型人才培养需要学科的交叉融合。以学科交叉为切入点,对无机及分析化学实验课程实验教学进行了改革和实践。以校内自来水和生活污水作为测试对象,采用高锰酸钾法测定了水样的化学需氧量。通过实验旨在提高学生的实践动手能力、跨学科思维能力、数据收集计算能力以及解决实际问题能力,增强学生环境保护意识,适合为化学、环境工程和资源循环科学与工程等专业学生开课。问卷调查发现,学生和教师对该实验内容都给予了高度评价,教学实践效果良好。The cultivation of comprehensive talents in the field of modern engineering requires interdisciplinary integration.Using interdisciplinary integration as the starting point,reform and practice of experimental teaching was conducted in the inorganic and analytical chemistry experiment course.Using the tap water and domestic sewage in the campus as the object of this study,the chemical oxygen demand was measured using the potassium permanganate method.The experimental aims were to improve the interdisciplinary thinking,data calculation,and practical problem-solving abilities of the students and to enhance their awareness of environmental protection,which is desirable for students majoring in chemistry,environmental engineering,and resource cycle science and engineering.The questionnaire revealed that students and teachers gave a high evaluation to the experimental content,and the experiment achieved good teaching practice results.
