Abstract：ObjectiveTo explore the application value of mobile problem-based learning (PBL) teaching method combined with ultrasonic simulation system in ultrasonic diagnosis teaching. MethodsA total of 48 fourth-year ultrasound medicine undergraduates interning at the Affiliated Hospital of Jining Medical University from September to November 2020 were selected. According to random number table method, they were randomly divided into experimental group （n=24） and control group （n=24）. Experimental group was adopted mobile PBL teaching method in theory teaching and ultrasonic simulation system and traditional practice teaching method in practice teaching. Control group was adopted traditional teaching method in theory and practice teaching. After the training, the assessment and satisfaction survey were conducted to compare the theoretical scores, practical operation scores, total score of the two groups and their satisfaction with teaching. ResultsTheoretical score ［(44.70±3.54)points］, practical operation score ［(47.64±1.56)points］ and total score ［（92.35±3.25）points］ of the experimental group were significantly higher than those of the control group ［(38.20±4.69)points， (41.83±2.91)points, （80.04±6.17）points］, the differences were statistically significant (t=5.41, 36.00, 8.63, all P＜0.01). Total score of the teaching satisfaction of the experimental group ［(96.04±1.33)points］ was significantly higher than that of the control group ［(85.12±2.17)points］, with statistically significant difference (χ2=20.97, P＜0.01). ConclusionThe application of mobile PBL teaching method combined with ultrasonic simulation system in ultrasonic diagnosis teaching is more welcome than traditional teaching method, which can improve students′ theoretical and practical operation ability, and it is worth popularizing and applying in clinical teaching.
