“停课不停学”是“新冠疫情”防控期间高校因延期开学而实行的一项新举措，其中在线网络教学发挥了重要的作用。《材料力学》是工科类专业重要的基础课之一，为该学科学生后续专业课程的开展提供了基础。本文以疫情时期土木工程专业开设的《材料力学》课程为研究对象，以超星学习通为教学管理平台，QQ群为在线讲授和辅导答疑的交流平台，成功的完成了该课程在线教学过程。本文首先从在线教学课程的内容设计，其次通过数据分析了该课程在线教学过程中的访问量、到课率、作业完成率和考试成绩等在线教学效果，最后阐述了在线教学的优缺点和一些建议。综合表明，超星学习通和QQ群相结合的在线教学形式与线下教学相比同样受到学生的认可且参与性高，教学效果良好。 “Suspension of classes without suspension” is a new measure implemented by colleges and universities due to the delay of school opening during the period of “new crown epidemic” prevention and control, and online teaching has played an important role. “Mechanics of Materials” is one of the important basic courses for engineering materials majors, which provides a foundation for the development of follow-up professional courses. This article takes the “Materials Mechanics” course offered by civil engineering majors during the epidemic period as the research object, uses Chaoxing Xuetong as the teaching management platform, and QQ group as the communication platform for online lectures and guidance and answering questions. The online teaching process of this course has been successfully completed. This article first starts with the content design of the online teaching course, and then analyzes the online teaching effects, such as the number of visits, class arrival rate, homework completion rate and test scores during the online teaching process of the course through data.
