摘要

目的

探讨3D数字建模联合3D打印模型在临床五年制本科外科学（骨科）理论课堂辅助教学过程中的应用效果。

方法

2022年5月，选取西南医科大学2018级五年制临床医学专业本科33名学生按照单双学号分为试验组（17名）与对照组（16名）。试验组学生采用传统PPT教学+3D数字建模联合3D打印模型的教学方式；对照组学生采用传统PPT教学方式。以章节知识理论考试及教学满意度问卷调查评价教学效果。采用SPSS 25.0进行

检验、Mann-Whitney

检验、秩和检验和卡方检验。

结果

试验组章节知识理论考试成绩高于对照组，分别是（86.24±4.16）分和（82.50±6.06）分。教学满意度问卷调查结果显示，试验组在该方法对帮助骨科疾病理解及学习满意度[3（2，3）分vs. 2（2，2）分]、对提高学习兴趣满意度[2（2，3）分vs. 2（1，2）分]

、课堂创新满意度[3（3，3）分vs. 2（1.5，2）分]及课堂教学总体满意度[3（2，3）分vs. 2（2，2）分]

等方面均高于对照组，差异有统计学意义（

0.05）。

结论

采用3D数字建模联合3D打印模型辅助临床医学本科生骨科理论课堂教学，提供了三维具象模型，降低了学生的学习难度，有助于学生对骨科疾病的认识，提高了学生的学习兴趣，提升了临床理论课学生的教学满意度和学习成绩。

Abstract

Objective

To investigate the application effect of 3D digital modeling combined with 3D printed model in assisting the classroom theoretical teaching of orthopedics in five-year undergraduate students majoring in clinical medicine.

Methods

In May 2022

33 five-year undergraduate students majoring in clinical medicine in the class of 2018 in Southwest Medical University were selected and divided into experimental group with 17 students and control group with 16 students according to the odd or even student number. The students in the experimental group were taught by traditional PPT+3D digital modeling combined with 3D printed model

and those in the control group were taught by the traditional PPT teaching method. The teaching effect was evaluated by theoretical examination and a questionnaire survey on the degree of satisfaction with teaching. SPSS 25.0 was used to perform the

-test

the Mann-Whitney

test

the rank sum test

and the chi-square test.

Results

The experimental group had a significantly higher score of theoretical examination than the control group (86.24±4.16 vs. 82.50±6.06). The questionnaire survey on the degree of satisfaction with teaching showed that compared with the control group

the experimental group had a significantly higher degree of satisfaction with the understanding and learning of orthopedic diseases [3 (2

3) vs. 2 (2

0.05]

the improvement in learning interest [2 (2

3) vs. 2 (1

0.05]

classroom innovation [3 (3

3) vs. 2 (1.5

0.05]

and overall classroom teaching [3 (2

3) vs. 2 (2

0.05].

Conclusion

In assisting the classroom theoretical teaching of orthopedics in undergraduate students majoring in clinical medicine

3D digital modeling combined with 3D printed model can provide concrete 3D models

reduce the difficulties in learning

improve the awareness of orthopedic diseases

strengthen learning interest

and increase the degree of satisfaction with teaching and academic scores.
