Discussion on "Online Hybrid" Teaching of Engineering Drawing Course under the Background of Epidemic Situation

The COVID-19 epidemic has brought far-reaching influence to the teaching reform in colleges and universities. According to the instruction of the ministry of education in the background of epidemic situation, and based on the "Internet thinking" and the teaching objectives of engineering drawing, this paper expounds the idea of "Online hybrid" teaching in the background of epidemic situation. On the basis of the existing engineering drawing MOOC courses, teaching resources and network teaching environment, "Online hybrid" teaching model and online learning process of engineering drawing is established. In this paper, we carried out the moderate flipped online classroom teaching activities under the "Online hybrid" teaching mode, summarized the teaching effect and teacher-student evaluation of online "teaching" and "learning", compared the online teaching effect of engineering drawing with the offline entity classroom teaching effect during the epidemic period. Finally it concluded that there is no significant difference between the two in the learning effect, but the key to affect the online learning effect of students lies in Teachers' online teaching methods and students' learning methods. Through the summary, analysis and reflection of the implementation process of online teaching, this paper puts forward the implementation suggestions of online teaching hybrid teaching, in order to provide a reference for online teaching reform, and promote students' deep participation in online learning.
