摘要
为了公平和客观地评价无机及分析化学类实验成绩,依托"浙大化学实验教学中心"微信公众号,建设了"实验数据提交及评分"系统,实现了对标准溶液标定、产品测定、分光光度法测定以及活化能测定等20多个实验项目的数据提交、处理和评分。本系统受益面极广,方便了学生及时提交数据,提高了教师评判实验成绩的效率,取得了很好的应用效果。
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.
