Exploration and Practice of Student-Centered Online and Offline Blended Teaching Mode in Instrumental Analysis Experiment

In order to solve the issues of traditional experimental teaching methods, the student-centered and blended learning mode was put forward by using instrumental analysis experiment as an example. The hierarchical teaching education mode was carried out to meet the needs of personalized training. Based on the online learning platform of Daxia School, online and offline linked learning activities can effectively stimulate the students' interest and initiative in learning. This guides students to internalize knowledge and cultivates their high-level thinking and comprehensive ability of analyzing and solving problems, benefiting the all-round development of the students.
