摘要

目的

探索基于薄层CT影像的3D虚拟重建及打印技术在“网络云+双轨”教学中的应用前景。

方法

选取2021年4月至2022年4月期间在空军军医大学第二附属医院见习的医学学员共120名作为研究对象，分为试验组和对照组各60名。试验组采用3D虚拟重建及打印技术辅助的“网络云+双轨”教学；对照组采用“网络云+双轨”教学。经过6个月学习后，通过闭卷考试、技能操作、演讲答辩和问卷调查4种方式比较教学效果。采用SPSS 23.0进行

检验和卡方检验。

结果

试验组在出科考试中，理论知识考核（84.25±5.53）分、操作技能考核（87.68±5.72）分，均优于对照组的（79.43±6.69）分、（82.97±5.32）分，差异有统计学意义（

0.001）。试验组在演讲[（44.90±2.56）分]与答辩[（45.83±2.62）分]

两个环节中的成绩均高于对照组的（41.88±2.71）分、（43.85±2.56）分，差异有统计学意义（

0.001）。在调查问卷中，试验组见习学员的实践能力、主动学习能力、表达能力和实习积极性的评分均显著高于对照组（

0.001），获取信息能力的评分高于对照组，差异均有统计学意义（

0.001）。

结论

3D虚拟重建及打印技术辅助下的“网络云+双轨”教学可显著提升学员的客观学习效果与主观学习能动性，具有较高的教学应用与推广价值。

Abstract

Objective

To investigate the application prospect of 3D virtual reconstruction and printing technology based on thin-slice CT images in network cloud+dual-track teaching.

Methods

A total of 120 medical students who were on probation in The Second Affiliated Hospital of Air Force Medical University from April 2021 to April 2022 were selected as subjects and were randomly divided into experimental group and control group

with 60 students in each group. The students in the experimental group received 3D virtual reconstruction and printing technology combined with network cloud+dual-track teaching

and those in the control group received network cloud+dual-track teaching alone. After 6 months of learning

the teaching effect was compared by closed-book examination

skill operation

speech defense

and questionnaire survey. SPSS 23.0 was used for the

-test and the chi-square test.

Results

Compared with the control group in terms of department examination

the experimental group had significantly better scores of theoretical knowledge [(84.25±5.53) vs. (79.43±6.69)

0.001] and operational skills [(87.68±5.72) vs. (82.97±5.32)

0.001]. The experimental group had significantly higher scores than the control group in speech [(44.90±2.56) vs. (41.88±2.71)

0.001] and defense [(45.83±2.62) vs. (43.85±2.56)

0.001]. The questionnaire survey showed that compared with the control group

the experimental group had significantly higher scores of practical ability

active learning ability

expression ability

practice enthusiasm

and information acquisition ability (

0.001).

Conclusion

The network cloud+dual-track teaching model assisted by 3D virtual reconstruction and printing technology can significantly improve the objective learning effect and subjective learning initiative of students and has a relatively high value of teaching application and promotion.
