物理化学实验课程教学模式改革探索

Exploration of Reform on Instruction Mode of Physical Chemistry Experiment Course as the Instance of the Combustion Heat Determination

针对传统物理化学实验课程教学中存在的弊端,根据我校实际情况探索和实践了对该课程的教学模式改革。以燃烧热的测定实验为例,结合视频等媒介将部分理论知识提前在讲座中讲解。采用分组讨论的形式让学生对实验进行归纳总结。将数据处理方式由坐标纸上手工制图改为更精确高效的软件制图。将传统的考评方式改为预习报告、提问、操作、实验报告等方面的综合考评方式。实践证明新的教学模式达到了很好的效果。

In view of the disadvantage of the traditional teaching of physical chemistry experiment course,from the actual situation of Nanjing Xiaozhuang University,the instruction mode reform of physical chemistry experiment course was explored and implemented,as the instance of the experiment of the combustion heat determination,combined with the new instructional media such as video,introduced the installations,operation content and the principles of the experimental in the form of lecture before the operation step.The students the key operations were sum up,the reason of the error and how to decrease by means of group discussion were analyzed.It showed improvement of the data processing method form manual drawing on the coordinate paper to the accurate and efficient data processing software,such as Excel,Origin,etc.The evaluation had been changed from ex parte to comprehensive by synthetically considering preview report,answer questions,operation and lab report.Good effects appeared after taking the above measures.
