基于手机视频考核实验操作的探索与实践——以《分析化学》课的酸碱中和滴定考核为例

Exploration and Practice Of Mobile Phone Video-Based Experimental Skill Test——the test of acid-base titration in Analytical Chemistry as an example

针对现在的实验考核中存在的诸多问题,提出了用手机拍摄实验操作的视频,并以手机视频为依据评价学生操作的考核方法。该方法能促使实验考核公开、公正、公平,减轻教师考核工作量,并促进学生不断改进自己的操作。考核效果较为令人满意。

In view of the problems existing in present experiment test, the way using mobile phone to shoot the process of experimental manipulation is put forward in this paper. And the mobile phone video can be used as the assement method to evaluate students＇ operation. The method, which is to be proved satisfactory, can make the experiment test open,fair and just, reduce the teacher＇s workload, and encourage the students to improve their operation continually.
