绿色电化学储能器件超级电容器的实验设计与实践*

以超级电容器实验为例,将绿色化学科学研究转化为实验教学的基本设计思路,学习双电层电容器和法拉第准电容器的工作原理、组装及性能测试方法(循环伏安法和恒流充放电法),分析循环伏安曲线、比电容、能量密度和功率密度,总结2者的不同。实践结果表明:电化学基础和科学研究的成功联通,让学生对电化学概念和原理有了更深刻的理解,并获得关于清洁能源储存器件的实践经验,同时也增强了学生的绿色化学素养。     

基于翻转课堂的大学实验化学教学研究与实践

Experimental chemistry is an important public foundation course for the undergraduate student during their first year at Shihezi University. This paper introduces the teaching status and implementation of the experimental chemistry curriculum. Based on the student activities, this paper firstly constructs flipped learning mode of the experimental chemistry, combining the curriculum resource preparation with online and offline teaching. Secondly, the experimental chemistry curriculum takes deep integration of information technology and classroom teaching as an opportunity. Furthermore, the teaching implementation is carried out by the network teaching platform of Shihezi university. Finally, the student's questionnaire displays that it works well in improving the teaching quality.
