Abstract:

 For the demand of online teaching during the pandemic period，a new online teaching method based

on real-time feedback of question choice is proposed by considering the characteristics of large class teaching of college

physics courses and combined with the application experience of online MOOC courses and students' learning

habits.In this paper the problems faced in the online large-class teaching of college physics courses are analyzes

first，then the implementation plan of this method is comprehensively described through the designs of question

time，question type，assessment methods of choice question.Finally，through one semester's teaching practice，the statistical

results have showed that this method should effectively improve the quality of online teaching.

Key words: online teaching, college physics, real-time feedback, online teaching quality
