Abstract: Traditional analytical chemistry teaching does not fully reflect students' subjectivity, initiative and creativity. In view of the existing problems in analytical chemistry teaching, the cloud class class is used as a platform to build a three-stage mixed teaching mode before class, during class and after class, sort out the online teaching content, and use formative evaluation and summative evaluation to comprehensively evaluate students. The survey results show that more than 90% of the students think their ability of information collection, sorting and processing, the degree of knowledge mastery, innovation ability, the ability to cooperate with others, and the comprehensive ability to analyze and solve problems has been improved. However, students' participation in online links needs to be improved, and the enthusiasm of each member in group cooperation needs to be stimulated.
