Constructing Multiple Teaching System of Instrumental Analysis Experiment Based on Network Platform

There are several problems in the current experimental teaching of instrumental analysis. Students are not motivated to preview the experiment and have rare opportunities to practice. The student achievement assessment and teaching evaluation cannot be well quantified. To solve these problems, the multiple teaching system of instrumental analysis experiment was constructed for students based on a network platform from previewing the experiment to practicing in scientific research. A number of teaching stages have been implemented, including the exam, setting papers for examination, instrument booking for research purpose, and examination paper analysis to find out the weak link of teaching. It is necessary for the “question-answer” teaching in laboratory and network platform aided teaching to be combined together. Through practice researching, the average score of the students taught by the reform method was increased by 2.26 points. The multiple teaching system based on the network platform can play a positive role in training innovative and application-minded talents.
