E-learning has completely transformed how people teach and learn, particularly in the last three pandemic years. This study evaluated the effectiveness of additional procedure-specific video demonstrations through E-learning in improving the knowledge and practical preclinical skills acquisition of undergraduate dental students in comparison with live demonstration only. A randomized controlled trial was conducted for the second-year dental students in the College of Dentistry, Jouf University, to evaluate the impact of E-learning-assisted videos on preclinical skill competency levels in operative dentistry. After a brief introduction to this study, the second-year male and female students voluntarily participated in the survey through an official college email. Fifty participants were enrolled in the study after obtaining informed consent. The participants were randomly divided into two groups, twenty-five each. The control group (Group A) was taught using traditional methods, and the intervention group (Group B) used E-learning-assisted educational videos and traditional techniques. An objective structured practical examination (OSPE) was used to assess both groups. The faculty members prepared a structured, standardized form to evaluate students. After OSPE, statistical analysis was done to compare the grades of OSPE between Group A and Group B. Logistic regression analysis was done to express the effect of components of the OSPE on gender, cumulative gross point average (CGPA), Group A and Group B. The results showed a significant difference in the experimental groups after the intervention (p < 0.000). The simulator position parameter demonstrated that the participants had a significant competence level after the intervention by procedure-specific videos (p < 0.000) and an exponential value of 6.494. The participants taught by E-learning-assisted procedure-specific videos and traditional teaching strategies demonstrated an enhanced learning and skill competency level than participants who used only traditional teaching strategies.
电子学习彻底改变了人们的教学和学习方式,尤其是在过去的三年大流行期间。本研究评估了通过电子学习提供额外的特定程序视频演示在提高本科牙科学生知识和实践临床前技能方面的效果,与仅进行现场演示相比。在乔富大学牙科学院对二年级牙科学生进行了一项随机对照试验,以评估电子学习辅助视频对临床前技能能力水平的影响。在对本研究进行简要介绍后,二年级男女学生通过官方大学电子邮件自愿参与了调查。在获得知情同意后,有 50 名参与者被纳入研究。参与者被随机分为两组,每组 25 人。对照组(A 组)采用传统方法教学,干预组(B 组)采用电子学习辅助教育视频和传统技术。使用客观结构化实践考试(OSPE)评估两组。教师准备了一份结构化、标准化的表格来评估学生。OSPE 后,进行了统计分析,以比较 A 组和 B 组 OSPE 的成绩。进行了逻辑回归分析,以表达 OSPE 的组成部分对性别、累计总积分(CGPA)、A 组和 B 组的影响。结果表明,干预后实验组有显著差异(p < 0.000)。模拟器位置参数表明,参与者在接受特定程序视频干预后具有显著的能力水平(p < 0.000),指数值为 6.494。与仅使用传统教学策略的参与者相比,通过电子学习辅助特定程序视频和传统教学策略进行教学的参与者表现出更高的学习和技能能力水平。
