3D打印技术结合CBL教学模式在骨科临床教学中的应用

目的 以案例为基础的教学法(case-based learning,CBL)是一种以案例为导向提高学生学习效率的教学模式,3D打印技术作为新兴的科学技术越来越多的应用在现代医学应用之中。本研究为提高骨科的临床教学效率,故尝试采用3D打印技术集合CBL教学模式的新型教学方法,探究新型教学模式效果。 方法 选取蚌埠医学院2017级临床本科班二班的50名同学作为实验对象,并根据学号后2位数的奇偶性分为研究组(新教学法组)和对照组(传统教学法组),每组25名。新教学法组采用3D打印结合CBL教学模式进行临床教学,传统教学法组采用传统教学方式。在完成授课以后,进行统一的考核测试和评价量表调查,分析2组学生学习成绩分数及自我评定程度有无差异以评估新型教学模式的应用效果。 结果 在回收的50份有效问卷里,对照组理论平均成绩为(69.84±12.52)分、临床技能平均成绩为(68.96±12.65)分;研究组理论平均成绩为(83.16±10.46)分、临床技能平均成绩为(83.48±8.89)分。经过分析,采用新教学法学习的学生得分及其自我评定明显高于传统教学法组(均P<0.05)。 结论 相比传统的教学模式,3D打印技术结合CBL教学模式在骨科临床教学应用使抽象的知识具体化,增加了学生对骨科学习的兴趣,加深了学生对理论和实验知识的理解能力,提高了教学效率。 

Application of 3D printing technology combined with CBL teaching mode in clinical teaching of orthopedics

Objective To improve the clinical teaching efficiency of orthopedics, this study tries to adopt the new teaching method of 3 D printing technology and CBL teaching mode to explore the effect of the new teaching mode. Methods Total 50 students from the second class of clinical undergraduate class of 2017 of Bengbu medical college were selected as experimental subjects. According to the parity of the last two digits of the student number, they were divided into new teaching method group and traditional teaching method group, with 25 students in each group. The new teaching method adopted 3 D printing technology combined with CBL teaching model for clinical teaching, while the traditional teaching method group adopted the traditional teaching method. The 3 D printing technology combined with CBL teaching mode was used to teach and 50 experimental subjects were surveyed with evaluation scale to evaluate the application effect of the new teaching mode. After the completion of the lecture, a unified assessment test was conducted to analyze whether there were statistical differences between the two groups of students' academic performance scores and the degree of self-assessment. Results In the 50 valid questionnaires, the theoretical average score of the control group was 69.84±12.52, and the clinical average score was 68.96±12.65. The theoretical average score of the experimental group was 83.16±10.46, and the clinical average score was 83.48±8.89. The scores and self-assessment of students who studied with the new teaching method were significantly higher than those of the traditional teaching method group(all P<0.05). Conclusion Compared with the traditional teaching mode, the application of 3 D printing technology combined with CBL teaching mode in clinical teaching of orthopedics embodies abstract knowledge, increases students' interest in orthopedics learning, deepens their understanding of theoretical and experimental knowledge, and improves teaching efficiency.
