三维人体解剖模型结合CBL教学法在下肢骨折临床教学中的应用

Application of three-dimensional human anatomy model combined with CBL in clinical teaching of lower limb fractures

目的探究三维人体解剖模型(3D-body)结合以案例为基础的教学法(CBL)在下肢骨折临床教学中的应用效果。方法选取赣南医科大学附属兴国医院的2023年9月—2024年4月临床医学专业本科实习生48名作为研究对象,按照随机数字表法分为研究组24名、对照组24名。对照组实施传统的下肢骨折教学方法,研究组实施3D-body结合CBL教学方式,比较两组教学前后考核成绩、批判性思维能力(CTDI-CV评分)、教学评价的差异。结果相较于教学前,实习生教学后理论成绩、临床实践技能成绩均升高,且研究组教学后理论成绩、临床实践技能成绩较对照组更高(P<0.05)。相较于教学前,实习生教学后认知成熟度得分、开放思想得分、寻求真相得分、系统化能力得分、信心得分、求知欲得分、分析能力得分均升高,且研究组教学后批判性思维能力(CTDI-CV评分)较对照组更高(P<0.05)。研究组教学吸引力、手术方案制定能力、对典型骨折认识深度、教学满意度较对照组更高,对外架操作所需操作练习次数较对照组更低(P<0.05)。结论3D-body结合CBL教学应用于下肢骨折临床教学具有较好效果,可有效提高考核成绩与教学评价,利于实习生批判性思维能力形成。

Objective To explore the effectiveness of a three-dimensional human anatomy model(3D-body)combined with a case-based learning method(CBL)in the clinical teaching of lower limb fractures.Methods Forty-eight undergraduate interns majoring in clinical medicine from September 2023 to April 2024 from Xingguo Hospital affiliated with Gannan Medical University were selected as research subjects from September 2023 to April 2024.They were divided into research group(n=24)and control group(n=24)using the random number table method.The control group received the traditional teaching method,and the research group received instruction with the 3D-body model combined with CBL.The two groups were compared in terms of examination performance,critical thinking ability(CTDI-CV score),and teaching evaluation.Results After the implementation of teaching methods,both groups had increases in the scores of the theoretical examinations and clinical practice skill assessments and the research group even performed significantly better in the scores of both theoretical examinations and clinical practice skill assessments compared to the control group(P<0.05).Additionally,the research group exhibited significantly higher scores of cognitive maturity,open-mindedness,truth seeking,conclusion of knowledge,confidence,curiosity,analytical ability,and critical thinking ability compared to the control group(all P<0.05).Moreover,the research group performed significantly better in teaching attraction,surgical plan formulation ability,in-depths understanding of typical fractures,and satisfaction with teaching,but demonstrated significantly reductions of operation exercises required for external frame operation as compared to the control group(P<0.05).Conclusion 3D-body combined with CB is effective for enhancing clinical teaching of lower limb fracture.It can effectively improve the intern’s examination performances and elevate teaching evaluation.It is conducive to cultivating interns'critical thinking ability.
