Flipped classroom may overcome weaknesses of live demonstration in teaching orthodontic wire-bending. This study aims to compare the effectiveness between flipped classroom and live demonstration in transferring skills for fabricating Adams clasp. Forty third-year undergraduate dental students were assigned to two groups. The students in group LD (n = 20) attended a live demonstration while students in group FC (n = 20) attended a flipped classroom. Both groups were taught on skills to fabricate Adams clasp in a standardised way. Each student from both groups were asked to submit an Adams clasp for a blinded quality assessment by two trained and calibrated assessors using a 18-item rubric, followed by validated students' satisfaction questionnaires to evaluate their perceived satisfaction on the teaching method received. A crossover study was then conducted three weeks later where LD attended a flipped classroom while FC attended a live demonstration. Students' satisfaction questionnaires were again collected from each student for blinded analysis. Mean scores for the quality of Adams clasp were 9.775 and 9.125 for LD and FC, respectively. No significant difference was detected between the two groups. Statistically significant association was found for one statement on the questionnaire, "I found the classroom arrangements conducive for the wire-bending activity" (p = 0.010). No significant differences were found between the two groups for other statements (p > 0.05). In conclusion, within the limitations of the study, flipped classroom is equally effective as conventional live demonstration in transferring orthodontic wire-bending skills for fabrication of Adams clasp. However, students perceived the classroom arrangements during the flipped classroom significantly more conducive for teaching orthodontic wire-bending.
翻转课堂可能克服口腔正畸弓丝弯制示教的弱点。本研究旨在比较翻转课堂与现场演示在传递制作 Adams 卡环技能方面的效果。将 40 名三年级本科口腔医学生分为两组。LD 组(n = 20)参加现场演示,FC 组(n = 20)参加翻转课堂。两组均以标准化方式接受制作 Adams 卡环的技能培训。要求两组学生各提交一个 Adams 卡环,由两名经过培训和校准的评估者使用 18 项量表进行盲法质量评估,然后使用经过验证的学生满意度问卷评估他们对所接受教学方法的满意度。三周后进行交叉研究,LD 参加翻转课堂,FC 参加现场演示。再次从每位学生收集学生满意度问卷进行盲法分析。LD 组和 FC 组的 Adams 卡环质量平均得分为 9.775 和 9.125。两组之间未检测到显著差异。问卷中有一个问题“我发现教室安排有利于进行弯丝活动”(p = 0.010)存在统计学显著关联。其他陈述(p > 0.05)两组之间无显著差异。总之,在研究的限制范围内,翻转课堂与传统现场演示在传授正畸弓丝弯制技能以制作 Adams 卡环方面同样有效。然而,学生认为翻转课堂的课堂安排更有利于正畸弓丝弯制教学。
