The purpose of this pilot study was to examine if tablet technology with accompanying instructional videos enhanced the teaching and learning outcomes in a preclinical dental laboratory setting. Two procedures deemed most challenging in Operative Dentistry II were chosen for the development of instructional videos. A random sample of thirty students was chosen to participate in the pilot. Comparison of faculty evaluations of the procedures between the experimental (tablet) and control (no tablet) groups resulted in no significant differences; however, there was a trend toward fewer failures in the experimental group. Examination of the ability to accurately self-assess was compared by exploring correlations between faculty and student evaluations. While correlations were stronger in the experimental group, the control group had significant correlations for all three procedures, while the experimental group had significant correlations on only two of the procedures. Students strongly perceived that the tablets and videos helped them perform better and more accurately self-assess their work products. Students did not support requiring that they purchase/obtain a specific brand of technology. As a result of this pilot study, further development of ideal and non-ideal videos are in progress, and the school will be implementing a "Bring Your Own Device" policy with incoming students.
本试点研究旨在探讨在口腔临床前实验室环境中,平板电脑技术与配套教学视频是否能提高教学效果。选择了被认为在口腔 II 课程中最具挑战性的两项操作作为教学视频的开发内容。随机抽取了 30 名学生参与了试点研究。对实验组(平板电脑)和对照组(无平板电脑)的教师对这些操作的评价进行了比较,结果没有显著差异;但实验组的失败率有下降趋势。通过探索教师和学生评价之间的相关性,考察了学生自我评估准确性的能力。虽然实验组的相关性更强,但对照组在所有三项操作中都有显著相关性,而实验组只有两项操作有显著相关性。学生们强烈认为平板电脑和视频有助于他们更好地表现,并更准确地自我评估他们的作品。学生不支持要求他们购买/获得特定品牌的技术。基于这项试点研究,目前正在进一步开发理想和不理想的视频,学校将对新生实施“自带设备”政策。
