Abstract:

Using WeChat, three modules including before, during and after the lab class were established to assist in the analytical chemistry laboratory teaching, which expanded the time and space of laboratory teaching. Through WeChat interaction, the distance between teachers and students was brought closer, which stimulated the participation, enthusiasm and master consciousness of students. Using the comparative experiment method, the significant difference between the experimental class and the control class were analyzed. Taking the "measurement of hydrogen peroxide content" as an example, the average score of the experimental class (96.93) and the control class (86.73) presented significant difference with P < 0.01.
