基于3D打印模型的案例教学方法在气管插管教学中的应用

Application of case-based learning method based on 3D printing model in endotracheal incubation teaching

目的探讨基于3D打印模型的案例教学方法(case-based learning,CBL)在气管插管教学中的应用效果。方法采用整群抽样方法,选取2019年1月—2022年1月在浙江省丽水市人民医院进行临床实习的温州医科大学2015级、2016级、2017级五年制临床医学专业80名学生为研究对象。采用随机数字表法,将80名学生分为试验组和对照组,每组40名学生。试验组学生采用基于3D打印模型的案例教学方法,对照组学生采用传统教学方法。教学结束后,通过理论知识、操作技能考核成绩和问卷调查结果,比较两组学生各自教学方法的实施效果。两组学生按照不同级次分批进行教学和考核。结果理论知识考核结果显示,试验组学生成绩[(45.23±2.66)分]优于对照组学生[(40.94±3.41)分],其差异具有统计学意义(P<0.05);操作技能考核结果显示,试验组学生成绩[(48.26±2.33)分]优于对照组学生[(42.89±3.25)分],其差异具有统计学意义(P<0.05)。问卷调查结果显示,在学习兴趣、学习效率、主动的互动、知识掌握程度、总体教学满意度5个方面,试验组学生的评分均高于对照组学生,其差异均具有统计学意义(均P<0.05)。结论基于3D打印模型的案例教学方法,与传统教学方法相比,可以为学生带来全新的立体视觉感受和模拟体验,有助于提高学生的学习兴趣和效率,有助于学生将理论知识和操作技能掌握得更加牢固,教学满意度更高,值得进一步深入研究与推广应用。

Objective To explore the application effect of case-based learning method based on 3D printing model in tracheal intubation teaching.Methods A cluster sampling method was used to select 80 students majoring in clinical medicine of Grade 2015,2016 and 2017 in Wenzhou Medical University who were interned in Lishui People's Hospital in Zhejiang Province from January 2019 to January 2022 as the research objects.Eighty interns were divided into experimental group and control group according to random number table method.The experimental group of 40 students adopted case-based learning method combining 3D printing model;the control group of 40 students adopted traditional teaching method.After teaching,the teaching effects of the two groups were compared by theoretical knowledge exam,skill operation assessment score,and questionnaire survey results.Two groups of students were taught and assessed according to different grades of students.Results In terms of theoretical knowledge,the score of students in the experimental group(45.23±2.66)was higher than that in the control group(40.94±3.41),with a statistically significant difference(P<0.05).In terms of skill operation assessment score,the score of students in the experimental group(48.26±2.33)was higher than that in the control group(42.89±3.25),with a statistically significant difference(P<0.05).The questionnaire survey results showed that the scores of students in the experimental group were all higher than those in the control group in five aspects:learning interest,learning efficiency,active interaction,knowledge mastery,and overall satisfaction,with significant differences(all P<0.05).Conclusions The case-based learning method based on 3D printing model,compared with traditional teaching method,can bring students a new stereoscopic visual experience and simulation experience,improve learning interest and efficiency,master theoretical knowledge and skills more firmly,and achieve higher student satisfaction.It is worth further in-depth research and practical promotion.
