The purpose of this study was to compare computer-assisted instruction (CAI) with lecture format using recent hardware and software advances. A pre- and post-test was used to determine student performance and instructional preference. In addition, a post-instruction survey was used to determine student learning preferences.
Seventy-five first-year University of North Carolina (UNC) dental students who were registered for the introductory radiology course were asked to participate. All agreed and were randomly placed in one of three groups: interactive CD only, interactive CD and lecture, and lecture only. The content of the multimedia instruction focused on intraoral radiography. A pre- and post-test was administered to determine if there was a significant difference between interactive CD and lecture formats, and an evaluation instrument was used to determine if there was a student learning preference between CAI and lecture format. Analysis of covariance and the sign test were used to determine significance (p<.05).
There was no significant difference between pre- and post-test outcomes, indicating that similar learning took place using the interactive CD and/or lecture format. However, students preferred CAI to lecture format.
本研究的目的是利用最新的硬件和软件进展,将计算机辅助教学(CAI)与讲座形式进行比较。采用前测和后测来确定学生的表现和教学偏好。此外,还通过教学后调查来确定学生的学习偏好。
邀请了75名注册了放射学入门课程的北卡罗来纳大学(UNC)一年级牙科学生参与。所有人都同意并被随机分为三组之一:仅使用交互式光盘、交互式光盘加讲座、仅讲座。多媒体教学的内容集中在口腔内放射摄影。进行前测和后测以确定交互式光盘和讲座形式之间是否存在显著差异,并使用一种评估工具来确定CAI和讲座形式之间是否存在学生学习偏好。使用协方差分析和符号检验来确定显著性(p<0.05)。
前测和后测结果之间没有显著差异,表明使用交互式光盘和/或讲座形式发生了相似的学习。然而,学生更喜欢CAI而不是讲座形式。
