线上线下混合式教学改革——以计算方法课程为例

计算方法课程也称数值计算方法,在工科专业广泛开设,在航空航天相关专业中作为学科基础课程讲授,具有搭建基础课程与专业课程桥梁的作用。针对课时紧张、教学内容分支多、实践内容与航空航天工程领域结合不紧密等问题,课程教学团队开展线上线下混合式教学改革。通过竞赛性实验与在线测试激发学生兴趣,促使学生追求优秀;通过多维度全过程考核体系激励学生开展实践与自学;搭建SPOC线上课堂,课内强调重点与难点,课外拓展知识面,提高效率;建设贯穿全程的航天案例体系,帮助学生构建知识体系,贯彻学以致用。在已完成的300多名学生的教学中取得了良好的教学效果。

The course of Computational Methodsis widely taught in engineering subjects,is adopted as a specialized fundamental course for the aerospace related subjects,and plays a key role in the process of connecting the fundamental courses and the professional courses.The research is aimed at solving the problems of the insufficient course hours,the difficulties of students in knowledge hierarchy construction and application due to too many content branches,and the loose connection between the curriculum practice and the aerospace engineering area.The hybrid reform in education combining the online and offline teaching includes four aspects.First,the competition-style experiments and online validation is designed to arouse the students'interest,and help them to pursue excellence.Second,the multi-dimension whole-process assessment system is used to encourage the students to do more practices and study some contents by their own.Third,the SPOC-style online course is built to improve the teaching efficiency that the difficult and important parts are taught in the offline study time,and the online study time is mainly used to expand the knowledge.Fourth,a case-teaching system throughout the whole course is built,which can help students build the knowledge hierarchy and study for the purpose of application.The teaching reform has brought good effects in the completed teaching with more than 300 students.
