摘　　要：目的探讨基于互联网平台的案例学习(CBL)教学方法在放射诊断学教学中的应用效果。资料与方法前瞻性选取2018年9月—2021年10月于解放军总医院第一医学中心进行放射诊断学规范化培训轮转的65名临床专业学员为研究对象。2021级和2020级34名学员为研究组,采用基于互联网平台的案例学习教学方法;2019级和2018级31名学员为对照组,采取传统教学方法。培训后对两组学员进行理论知识测试、阅片考核及问卷调查评价。结果理论知识测试和阅片考核结果显示,研究组学员的理论成绩(90.62±3.46)分、阅片成绩(91.53±2.79)分和总成绩(91.07±2.68)分,均高于对照组[分别为(85.52±5.34)分、(87.52±4.03)分和(86.52±4.20)分],差异均有统计学意义(t=4.612、4.702、5.260,均P<0.01)。问卷调查结果显示,研究组学员对授课方式满意程度、学习主动性、学习效果满意程度均高于对照组学员,差异有统计学意义(χ^(2)=6.181、8.480、7.110,P均<0.05)。结论采用基于互联网平台的案例学习教学方法有助于提升学员的学习积极性和影像诊断水平,可以作为传统教学模式的必要替代和补充。Purpose To explore the teaching effect of case-based learning(CBL) via the internet in radiology. Materials and Methods From September 2018 to October 2021, sixty-five clinical trainees who underwent standardized training rotation of radiology in PLA Medical School were prospectively selected as the research subjects. Thirty-four students from the classes of 2021 and 2020 were selected as the experimental group, using CBL teaching method based on the Internet platform. Thirty-one students from the classes of 2019 and 2018 were selected as the control group, adopting the traditional teaching method. After the training, the two groups of students were tested for theoretical knowledge, imaging reading and questionnaire evaluation. Results According to the theoretical knowledge test and imaging reading, the theoretical score(90.62±3.46) points, imaging reading score(91.53±2.79) points, and total score(91.07±2.68) points of experimental group were significantly higher than those of the control group(85.52±5.34 points, 87.52±4.03 points and 86.52±4.20 points, respectively)(t=4.612,4.702, 5.260, all P<0.05). The satisfaction of teaching method, learning initiative and learning effect of experimental group were significantly higher than those of the control group via questionnaire survey(χ^(2)=6.181, 8.480, 7.110, all P<0.05). Conclusion The CBL teaching method via the internet can improve students’ learning enthusiasm and imaging diagnostic ability, this method can be used as a necessary replacement and supplement to the traditional teaching model.
