The reform of experimental teaching content The instrument analysis involves many types of instruments and is limited by the number of hours of experimental teaching. For a long time, the teaching of instrument analysis experiments is mostly a confirmatory experiment. The experimental contents are old and the students usually only need to mechanically follow the teaching materials. The experimental procedure can be completed with a simple operation. Students' interest in learning is not high, and it is very unfavorable for students to cultivate their innovative ability and innovative spirit.

In order to change this situation, under the premise of meeting the requirements of the experimental syllabus, we have carried out a major reform of the teaching content of instrumental analysis experiments, and selected 17 new comprehensive and design experiments using different approaches. Based on the high academic enthusiasm of our teachers and the current status of research projects, we are very careful to extract new experimental projects from the teachers’ scientific research content.

Since these experimental contents are usually problems in scientific research frontier or actual production, by making students understand the process and background of experimental content generation, not only greatly increase the interest of the experiment, but also the process of using the involved experimental methods to solve practical problems. A deeper understanding. For example, we have extracted the electrochemical research method for artemisinin established in scientific research as the topic of designing experiments, which not only allows students to grasp the methods of electrochemical analysis, but also allows students to understand the mechanism of pharmacological activity of artemisinin drugs. Its relationship with electrochemical properties.
