Application of CBL Teaching Method combined with 3D Reconstruction Model in Standardized Training of Thoracic Surgery Residents
Objectives This study explored the effect of case-based learning(CBL)combined with three-dimensional reconstruction model in the standardized training of thoracic surgery residents.Methods A total of 48 residents or rotating postgraduate students who were trained in Xuanwu Hospital of Capital Medical University from December 1st,2020 to August 1st,2022 were selected as the research subjects.The subjects were randomly divided into experimental group and control group.The teaching content was the anatomical structure of the lung segment.The experimental group adopted CBL combined with three-dimensional reconstruction model of the lung,while the control group adopted the traditional teaching method.After four hours of teaching,the end point of observation was:the test results and teaching effects of the two groups of subjects.Results The experimental group showed better overall exam scores than the control group(83±3.31 vs 67±7.83;P=0.02).In terms of teaching effectiveness evaluation,the experimental group showed a satisfaction rate of 96%,92%,83%,96%,and 92%in mobilizing learning interest,cultivating clinical thinking,understanding the surgical process,recalling clinical knowledge,and understanding the learning content,respectively,which were better than the control group's 67%,67%,50%,63%,and 67%,and the differences were statistically significant(P＜0.05).Conclusions Therefore,CBL teaching method combined with 3D reconstruction model could achieve better teaching effect in clinical teaching of thoracic surgery,especially in lung anatomy.
