Abstract: This article proposes a blended online and offline teaching approach for probability theory and mathematical statistics courses based on the OBE concept, in response to the opportunities and challenges of higher education in the era of big data. According to the characteristics of probability theory and mathematical statistics courses, the OBE teaching objectives were first determined, then the teaching content was adjusted, and a variety of teaching methods were designed. Finally, the online and offline hybrid teaching paths were systematically designed from five aspects of teaching platform resource preparation, pre class, in class, after class, and teaching evaluation, so as to improve students'learning interest, enhance students'autonomous learning participation, and achieve the OBE teaching objectives.
