3D打印模型辅助CBL教学法在骨科临床教学中的应用

The application of case-based learning teaching with the three-dimensional printing model in the orthopaedic clinical teaching

目的探讨3D打印模型辅助CBL教学法在骨科临床教学中的应用和效果。方法从教学效果问卷调查与教学内容测试考核两方面,评估3D打印模型辅助CBL教学法在骨科临床教学中的应用效果,并与床边带教教学法比较。结果3D打印模型辅助CBL教学法组学生在教学吸引力、知识掌握程度、临床思维能力、技能操作能力和临床沟通能力评分高于床边带教教学法组(P<0.05)。3D打印模型辅助CBL教学法组学生在病史采集和查体,影像学资料分析,骨折描述与分型,诊断,治疗方案的评分高于床边带教教学法组(P<0.05)。结论3D打印模型辅助CBL教学法提高了学生的学习兴趣和临床综合能力,提升了学生对知识掌握的广度和深度。

Objective To evaluate the role of the case-based learning(CBL)teaching with the three-dimensional(3D)printing model used in the orthopaedic clinical teaching.Methods This study explored the result of two different teaching in the orthopaedic education.The questionnaire of teaching effectiveness and test scores after teaching were done in the students,who were trained by CBL teaching with 3D printing model and bedside teaching respectively.Results Students taught by CBL teaching with 3D printing model could get more scores in the teaching attraction,the degree of grasping knowledge,the skill of the clinical analysis,the skill of clinical operation and the skill of clinical communication compared with the bedside teaching(P<0.05).Students taught by CBL teaching with 3D printing model could get more scores of the clinical skills,including the inquiry of history of patients and physical examination,the analysis of radiographic information,the classification of fracture,the diagnosis and the strategy of treatment compared with the bedside teaching(P<0.05).Conclusion CBL teaching with 3D printing model can stimulate the students'interest in learning and increase their general clinical skills.It is of benefit for students to grasp the knowledge of orthopaedic surgery precisely and extensively.
