“线上线下”结合的化学实验教学模式改革

Chemistry Experiments Teaching Mode Based on“Online+offline”

在化学实验模块化教学改革中,存在实验课时少,实验室周转紧张,学生不能系统学习化学实验课程等问题。针对此现状,设计了"虚拟仿真实验"镶嵌在实验室实验教学中,组成了"线上线下"相结合的实验教学模式。基础知识采用线上自学,然后通过实验训练加以巩固;模块实验观看视频后进行操作训练;综合实验学生通过线上自学后申请进入实验室操作,完成整个实验教学过程。该实验教学模式不仅解决了现存问题,而且使学生有充分的独立思考空间,强烈的参与实验意识和完整实验操作技巧的训练。

The problems of less hours of experiment and limited availability of labs appeared with the modular teaching reform of chemistry experiment, which leads the students to fail to learn chemistry experiment courses systematically. ＂Virtual simulation experiment＂ was designed as a supplement in lab-based chemistry experiments in order to solve these problems, and the reform of chemistry experiments teaching mode based on ＂online＋offline＂ was studied. The basic knowledge of experiment was learned by self-study on the line and consolidated through experimental training. The module experiment would be trained after watching video. Comprehensive experiment would be applied for laboratory operation after online self-study. Then the whole experiment teaching process was completed. The problems of less hours of experiment and limited availability of labs were solved. The aim of training the student＇s practical ability, independent thinking ability and innovative thinking ability has been achieved.
