摘　　要：大学物理实验传统教学模式为线下讲授,一般是教师讲授原理与操作,学生再自己动手实验、记录处理数据、计算实验结果、误差分析等.由于新冠疫情原因,今年很多实验类课程难以开展.教师致力于线上开展基础实验和居家实验,取得了较好效果.研究在齐齐哈尔工程学院范围内,学生线上学习空气比热容比测定实验的学习效果.结果显示:21个班级的实验报告平均提交率是94%,平均正确率是89%.可见空气比热容比线上实验教学效果比较理想.The traditional teaching mode of college physics experiment is offline teaching.Generally,teachers teach principles and operations,and students do experiments by themselves,record and process data,calculate experimental results,and analyze errors.Because of the coronavirus disease 2019(COVID-19)epidemic situation,many experimental courses are difficult to carry out this year.Teachers are committed to conduct basic experiments and home experiments online,and they have achieved good results.In this paper,the students’online learning effect of experiment of determining air specific heat ratio in Qiqihar institute of technology is studied.The results show that the average submission rate of the experimental report of 21 classes is 94%,and the average correct rate is 89%.It can be seen that the online experimental effect of air specific heat capacity is ideal.
