| 目的 探讨3D打印技术结合翻转课堂在耳鼻咽喉头颈外科实习教学中的应用。方法 将空军军医大学2013级临床医学专业本科实习学生共68人分为实验组（34人）和对照组（34人）。实验组采用3D打印技术结合翻转课堂，对照组采用传统教学。通过问卷调查及考核基础知识和临床技能评价教学效果，采用SPSS 20.0对组间数据进行成组t检验。结果 实验组理论考试成绩高于对照组[（34.79±2.20） vs. （31.73±3.12）]，差异有统计学意义（t=4.676，P=0.000）；实验组临床技能考核成绩高于对照组[（50.06±2.98） vs. （45.82±4.68）]，差异也具有统计学意义（t=4.449，P=0.000）。实验组学生问卷调查显示，实验组有31名（91.2%）学生认为新教学方式能激发学习兴趣，33名（97.0%）学生认为能提高学习效率，25名（73.5%）学生认为3D模型制作精良，32名（94.1%）学生认为提高了临床技能，28名（82.4%）学生认为增强了师生间互动交流，29名（85.3%）学生认为没有增加学习负担。结论 在耳鼻咽喉头颈外科实习教学中采用3D打印技术结合翻转课堂，能够提高学生的学习兴趣和成绩，并进一步提高其临床技能，值得推广。 |

| Objective To investigate the application of 3D printing in the flipped classroom in the practice teaching of otolaryngology-head and neck surgery. Methods A total of 68 medical undergraduates of the Grade 2013 in Air Force Medical University were divided into experimental group and control group, with 34 undergraduates in each group. The undergraduates in the experimental group received the teaching method of 3D printing in the with flipped classroom, and those in the control group received traditional teaching. The teaching effect was evaluated by questionnaire and examinations of basic knowledge and clinical skills, Independent-samples t test was used for between-group comparison with SPSS 20.0. Results Compared with the control group, the experimental group had significantly higher scores in theoretical examinations (34.79±2.20 vs. 31.73±3.12, t=4.676, P=0.000) and clinical skill examination (50.06±2.98 vs. 45.82±4.68, t=4.449, P=0.000). The questionnaire survey showed that among the 34 undergraduates in the experimental group, 31(91.2%) thought that the new teaching method could increase their learning interest, 33(97.0%) believed it could improve learning efficiency, 25(73.5%) believed the models obtained by 3D printing had good quality, 32(94.1%) felt that it could improve clinical skills, 28 (82.4%) thought it could enhance the interaction between students and teachers, and 29(85.3%) thought it did not bring extra burden. Conclusion The teaching method of 3D printing combined with flipped classroom in the practice teaching of otolaryngology-head and neck surgery can improve students' learning interest, academic scores, and clinical skills, and therefore, it holds promise for application in teaching. |
