Abstract: The course of Principle and Application of Microcontroller Unit (MCU) is an important carrier to train electronic engineering students to master the application technology of MCU. Its classroom teaching is the main channel to implement teaching tasks. In view of the problems of insufficient learning drive and low teaching output caused by the“indoctrination”teaching with teachers as the center, teaching materials as the content and knowledge transfer as the goal in traditional teaching, combined with the current Engineering Education Accreditation (EEA), the BOPPPS teaching mode is introduced, and the“super star learning”network teaching platform is used to integrate and optimize teaching resources, construct timely and effective closed-loop teaching feedback, and explore the implementation strategy of single-chip classroom teaching. The teaching practice shows that the BOPPPS teaching mode emphasizes the student as the main body, improves student participation in teaching activities, has a clearer real-time learning situation analysis function, can help teachers to reflect on teaching and adjust the teaching content, so it can stimulate students'learning enthusiasm and effectively improve the quality of MCU classroom teaching.
