| 目的 探讨混合式教学在医学影像诊断专业大学本科生临床实习中的应用效果。方法 选取2017至2019年在中国科学院大学重庆医院放射科实习的医学影像诊断专业60名大学本科生作为研究对象，分为试验组和对照组，各30名学生。试验组在实习期间采用混合式教学（根据不同的教学场景运用授课教学法、案例教学、问题教学、团队教学），对照组采用传统教学。实习结束时，比较两组实习学生的出科考试成绩，并采取问卷调查了解学生对教学的满意度。采用SPSS 19.0进行t检验和卡方检验。结果 出科理论知识考试成绩方面，试验组为（90.27±5.38）分，对照组为（83.13±7.57）分，差异有统计学意义（t=4.21，P<0.001）；出科读片分析考试成绩方面，试验组为（90.07±4.80）分，对照组为（82.13±8.71）分，差异有统计学意义（t=4.37，P<0.001）。满意度调查显示，对教学总体满意度中试验组"非常满意"为76.7%（23/30），对照组"非常满意"为50.0%（15/30），差异有统计学意义（χ2=6.57，P=0.037）。结论 混合式教学在医学影像诊断专业大学本科实习生的教学中具有很好的效果。 |

| Objective To explore the application effect of blended learning in clinical practice of undergraduate students majoring in medical imaging diagnosis. Methods A total of 60 undergraduate students majoring in medical imaging diagnosis who practiced in the Department of Radiology of Chongqing General Hospital from 2017 to 2019 were selected as subjects. The students were divided into experimental group and control group, each with 30 students. During the internship, the experimental group adopted the blended learning, including lecture-based learning, case-based learning, problem-based learning and team-based learning according to different teaching scenarios. While the control group adopted the traditional teaching mode. At the end of the internship, the test scores of the two groups of intern students were compared, and the satisfaction degree of the teaching was investigated by questionnaire. SPSS 19.0 was used to conduct t-test and Chi-square test. Results The score of theoretical knowledge examination in the experimental group was (90.27±5.38) points, and that in the control group was (83.13±7.57) points. The difference between the two groups was statistically significant (t=4.21, P<0.001). The score of imaging analysis examination in the experimental group was (90.07 ± 4.80) points, and that in the control group was (82.13±8.71) points. The difference between the two groups was statistically significant (t=4.37, P<0.001). The results of the satisfaction survey showed that the overall satisfaction with teaching was 76.7% (23/30) in the experimental group and 50.0% (15/30) in the control group, with statistically significant difference (χ2= 6.57, P=0.037). Conclusion The blended learning has a good effect in the teaching of undergraduate students majoring in medical imaging diagnosis. |
