Abstract: Objective To explore the effect of Problen-Based Learning（PBL）step-by-step teaching method in the online and offline mixed teaching of clinical skills for medical students. Methods Fifty-eight interns majoring in clinical medicine of grade 2019 in Nanping First Hospital affiliated to Fujian Medical University were selected as the research object,they were divided into two groups by drawing lots with even and odd numbers,namely,the study group and the control group,with 29 cases in each group．The study group conducted online and offline mixed teaching in a “one-on-one” way based on the step-by-step PBL teaching method after theoretical teaching,while the control group received regular offline teaching,and the teaching effects of the two groups were compared. Results The students of the study group participated in 5 clinical skills assessment,including disinfection towel（95.23±3.18）,tracheal intubation（95.19±3.26）,chest puncture（95.15±3.35）,lumbar puncture（95.28±3.17）and pediatric lumbar puncture（95.11±3.45）,were significantly better than those of control group（88.23±4.01）,（87.89±4.59）,（86.23±3.78）,（87.22±3.89）,（86.23±3.67）（t=7.366,6.983,9.510,8.650,9.494,P<0.05）．The comprehensive ability improvement of students in study group was better than that in control group（χ²=6.444,5.497,5.497,6.444,7.733,P<0.05）．The evaluation was made from the aspects of teacher training attitude（7 items）,training method（15 items）,training time（3 items）and training effect（11 items）．The clinical skill training teaching effect scores of study group（6.67±0.35）,（12.23±2.23）,（2.44±0.29）,（9.23±2.56）,（30.34±4.45）were significantly higher than those of control group（4.12±1.45）,（10.12±2.17）,（9.23±2.56）,（1.68±0.56）,（7.23±2.12）,（24.34±3.45）（t=9.206,3.652,6.490,3.240,5.738,P<0.05）. Conclusions Based on PBL step-by-step teaching method after theoretical teaching,the training method of clinical skills for medical students is established by “one-to-one” online and offline mixed teaching,can improve the clinical skills and comprehensive ability of interns and get high evaluation from students．
