摘要：

通过微信建立实验前、实验中、实验后三个模块，辅助分析化学实验教学，拓展了实验教学的时间和空间，通过微信互动，拉近了师生间的距离，激发了学生实验的参与积极性和主体感。利用对比实验法，将实验班与对照班的实验成绩进行显著性分析。以实验“过氧化氢含量的测定”为例，实验班平均成绩（96.93），对照班平均成绩（86.73），t=5.819，P < 0.01，比较差异具有统计学意义。

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.
