以教师为中心的星型拓扑线上教学面临的挑战及其应对

摘要文章针对线上教学以教师为中心的星型拓扑结构的特点，将线上教学中面临的问题和挑战归纳为教学硬件、网络平台、教学方法、学习状态和教学互动五个方面。在分析问题产生原因及特点的基础上，以液压传动与气动课程的线上教学为例，分别从课前准备、课堂讲授和课后交流三个方面提出改进教学设计的思路。

Abstract  According to the characteristics ofthe teacher centered star topology in online teaching， this paper summarizes the problems and challenges faced in online teaching into five aspects： teaching hardware， network platform， teaching methods， learning status and teaching interaction. On the basis of analyzing the causes and characteristics of the problems， taking the online teaching of hydraulic transmission and pneumatic as an example， this paper puts forward the ideas of improving the teaching design from three aspects： pre-class preparation， classroom teaching and post-class communication.

Keywords  online teaching; teacher-centered star topology; teaching method; hydraulic transmission
