Abstract

Introduction: Teaching methodologies have evolved from traditional lecturing to include the utilisation of recording technologies. This study aims to assess the impact of three teaching methods: (written instruction, lecture, video-recorded and live demonstration) of a maxillary wax-rim construction on students' performance and to explore students' satisfaction and preference for teaching methods.

Materials and methods: The study was designed as a multiarm parallel-group randomised trial. A total of 106 third-year undergraduate dental students at the University of Jordan during the 2023/2024 academic year were recruited. Students were enrolled in Prosthodontics Laboratory-1 course and had not taken this laboratory before or failed third year. Students were randomised using a randomisation software into three groups based on maxillary wax-rim construction teaching methods: written instruction, lecture, video-recorded and live demonstration. Students' wax rims were marked by numbers to ensure blinding of three examiners who conducted anterior and posterior rim measurements (primary outcome). Students' satisfaction and preferences (secondary outcome) were also assessed by completing a nit questionnaire.

Results: Group 1 (written instruction lecture) included 34 students, Group 2 (video-recorded demonstration) 35 and Group 3 (live demonstration) included 37 students, with two students dropping out due to absence. Groups 1 and 2 performed lower than group three regarding posterior rim height and width (p < 0.05). Groups 2 and 3 performed better regarding anterior rim height and width compared to Group 1 (p < 0.05). Most of the students (86%) preferred live demonstration over other methods of teaching.

Conclusion: Live and video-recorded demonstrations improved students' performance in achieving comparable wax-rim parameters to reference values compared to written instruction lectures, with a preference for live demonstrations. Integrating these methods into preclinical prosthodontic curricula can enhance practical learning and skill development.

牙科学生在口腔修复实验室的表现:一项比较书面教学、录像和现场演示的随机试验。
教学方法已经从传统的讲课发展到包括录音技术的使用。本研究旨在评估上颌蜡环构造的三种教学方法(书面教学、讲座、录像和现场演示)对学生成绩的影响,并探讨学生对教学方法的满意度和偏好。材料和方法:本研究设计为多臂平行组随机试验。在2023/2024学年,约旦大学共招募了106名牙科本科三年级学生。学生参加了口腔修复学实验室-1课程,之前没有参加过该实验室或第三年不及格。采用随机化软件将学生根据上颌蜡环施工教学方法随机分为书面指导、讲座、视频录制和现场演示三组。学生的蜡边用数字标记,以确保进行前后边缘测量的三名审查员的盲性(主要结果)。学生的满意度和偏好(次要结果)也通过完成一份问卷来评估。结果:第1组(书面指导讲座)34人,第2组(视频演示)35人,第3组(现场演示)37人,其中2人因缺课而退学。第一组和第二组在后缘高度和后缘宽度方面的表现低于第三组(p结论:与书面指导讲座相比,现场和视频录制的演示提高了学生在获得与参考值相当的蜡缘参数方面的表现,并且偏爱现场演示。将这些方法整合到临床前的修复课程中,可以提高实践学习和技能发展。

期刊介绍: The aim of the European Journal of Dental Education is to publish original topical and review articles of the highest quality in the field of Dental Education. The Journal seeks to disseminate widely the latest information on curriculum development teaching methodologies assessment techniques and quality assurance in the fields of dental undergraduate and postgraduate education and dental auxiliary personnel training. The scope includes the dental educational aspects of the basic medical sciences the behavioural sciences the interface with medical education information technology and distance learning and educational audit. Papers embodying the results of high-quality educational research of relevance to dentistry are particularly encouraged as are evidence-based reports of novel and established educational programmes and their outcomes.
