This paper designs the experiment of PBL teaching mode reform based on the microcomputer system and embedded application course group, analyzes the domestic research status of PBL teaching mode, and analyzes and summarizes the teaching effect of PBL. The average score of the experimental class with PBL teaching was 74.76 points, and the passing rate reached 95.13%; while the average score of the control group was 70.21 points, and the passing rate was 92.30%.
