This article explores and proposes a blended teaching model based on micro courses to address the drawbacks of traditional university physics experimental teaching models.Take the measurement of Young's modulus as a case study,three teaching stages were designed in detail:pre class self-learning,in class deepening training,and post class consolidation and expansion.This teaching model emphasizes student-centered interaction and exploration,and through the clever use of micro courses,it enhances the fun and participation of experimental classrooms,which is expected to provide new ideas for the reform of university physics experimental teaching.
