Abstract In order to grade chemistry experimental data fairly and objectivity, an online system of “data input and grading” has been applied, based on the Wechat public platform of “chemistry experiment teaching center of Zhejiang University”. This system achieved the automatic processing-grading on more than 20 inorganic and analytical chemistry experiments, such as the calibration of standard solutions, the synthesis and characterization of inorganic products, determination of an unknown sample using spectrophotometric method, measurement of the activation energy. This system made students input data more easily, let teachers grade the experiment more efficiently, achieved great teaching effects.
