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
