目的 探讨增强现实技术在脊柱外科手术学教学中的应用效果。方法 本研究采用试验对照方法。2018年9月至2019年1月,选择武汉大学2018级外科学专业50名研究生为研究对象。这些研究生均在武汉大学人民医院实习。在脊柱外科手术学教学中,试验组采用增强现实技术教学方式;对照组采用传统教学方式。教学结束后,对两组研究生进行考试和问卷调查,以评价增强现实技术的教学效果。结果 试验组研究生理论考试平均成绩为87.76分,对照组研究生为78.24分,其差异具有统计学意义(t=9.559,P<0.05)。问卷调查结果显示,在满意度调查比较中,试验组与对照组研究生在学习兴趣、课堂氛围、知识掌握、重难点理解和学习能力提高上的评分为:(88.64±3.62)分比(77.92±3.89)分、(87.16±4.12)分比(75.96±3.66)分、(89.84±3.04)分比(80.12±4.49)分、(89.00±4.26)分比(76.88±3.70)分、(89.80±3.23)分比(79.72±3.91)分,其差异均具有统计学意义(均P<0.05)。结论 在脊柱外科手术学教学中,采用增强现实技术教学方式取得了良好的教学效果。该教学方式有利于提高研究生的学习能力和临床思维能力。

Objective To explore the application effects of Augmented Reality technology in spinal surgery training. Methods Experimental control method was used in this study .From September 2018 to January 2019, 50 graduates majoring in clinical surgery at Wuhan University were selected as research subjects. The students in this study all practiced in Renmin Hospital of Wuhan University. In the training of spinal surgery, the experimental group adopted the teaching method of augmented reality technology. The control group adopted traditional teaching methods. By the end of the training, the two groups of students were tested and asked to evaluate the learning gain from the teaching process with augmented reality technology. Results The average scores of the experimental group and the control group were 87.76 and 78.24 respectively. The difference is significant (t=9.559,P<0.05) .The results of the questionnaire showed that the scores covering five points of the experimental group and the control group were (88.64±3.62)vs.(77.92±3.89),(87.16±4.12)vs.(75.96±3.66),(89.84±3.04)vs.(80.12±4.49),(89.00±4.26)vs.(76.88±3.70),(89.80±3.23)vs.(79.72±3.91) , the differences are significant (all P<0.05). Conclusions In the training of spinal surgery, the augmented reality has achieved good teaching effect. This teaching method is conducive to the improvement of students' capacity building of learning and clinical reasoning, so is worthy of further research and promotion.
