口腔正畸学线下实验课与线上实验课教学效果的对比分析——以临床检查和模型测量为例
Comparative Analysis on the Teaching Effect of Offline Experiment Course and Online Experiment Course of Orthodontics—Taking Clinical Examination and Model Analysis as an Example

目的：本研究以《口腔正畸学实验》——临床检查和模型测量部分为例，探讨疫情下特殊时期线上数字化实验的教学的实施效果。方法：以2017级和2018级口腔医学专业五年制本科生为研究对象。2017级参加线下实验课程，作为线下组；2018级因受到疫情影响，参加2022年口腔正畸学线上数字化实验课程，作为线上组，对比研究两组错合畸形分类、临床检查和模型测量的成绩。结果：错合畸形分类部分，线上组成绩较线下组高，有统计学差异(P < 0.05)；临床检查线下组成绩较线上组高，有统计学差异(P < 0.05)；模型测量部分两组成绩无统计学差异(P > 0.05)；总成绩显示两组无统计学差异(P > 0.05)。结论：线上数字化实验教学在错合畸形的分类和模型测量中取得较好的教学效果，临床检查部分教学效果不佳。
Objective: This study takes “Orthodontics Experiment”—clinical examination and model measure-ment as an example to explore the implementation effect of online digital experiment teaching in special period under epidemic situation. Methods: The 2017 and 2018 five-year undergraduates majoring in stomatology were selected as the research objects. The 2017 class participated in the offline experimental course as an offline group; the 2018 class participated in the online digital experimental course of orthodontics in 2022 due to the epidemic, as an online group. The grades of malocclusion classification, clinical examination and model analysis were compared between the two groups. Results: In the classification of malocclusion, the score of the online group was higher than that of the offline group, with a statistical difference (P < 0.05). The score of the offline group of clinical examination was higher than that of the online group, with a statistical difference (P < 0.05); there was no statistical difference between the two groups in the model analysis part (P > 0.05). The total score showed no statistical difference between the two groups (P > 0.05). Conclusion: Online digital experimental teaching has achieved good teaching effect in the classification of malocclusion and model analysis, but the teaching effect of clinical examination is not good.
