Due to the impact of COVID-19

the online problem-based learning (PBL) teaching mode was first implemented based on the curriculum integration of basic medicine and clinical medicine in our university in 2020. A total of 357 eight-year program clinical medicine students from three grades participated in the online PBL courses. The students have had related skills and knowledge of integration curriculum

and the teachers have carried out sufficient analysis of learning situation

preparation of software and hardware

as well as teaching design. Teachers and students has communicated with each other smoothly and cooperated closely through the Tencent Conference software platform

therefore this teaching mode has gained better feedback among students

with higher satisfaction of courses and significantly improved students' learning enthusiasm. The curriculum integration has laid the foundation for the case design and application of online PBL teaching

while the success of online PBL teaching has also reflected the original intention of curriculum integration reform.
