BACKGROUND
The importance of using technologies such as e-learning in different disciplines is discussed in the literature. Researchers have measured the effectiveness of e-learning in a number of fields.Considering the lack of research on the effectiveness of online learning in dental education particularly in Iran, the advantages of these learning methods and the positive university atmosphere regarding the use of online learning. This study, therefore, aims to compare the effects of two methods of teaching (virtual versus traditional) on student learning.
METHODS
This post-test only design study approached 40, fifth year dental students of Shiraz University of Medical Sciences. From this group, 35 students agreed to participate. These students were randomly allocated into two groups, experimental (virtual learning) and comparison (traditional learning). To ensure similarity between groups, we compared GPAs of all participants by the Mann-Whitney U test (P > 0.05). The experimental group received a virtual learning environment courseware package specifically designed for this study, whereas the control group received the same module structured in a traditional lecture form. The virtual learning environment consisted of online and offline materials. Two identical valid, reliable post-tests that consisted of 40 multiple choice questions (MCQs) and 4 essay questions were administered immediately (15 min) after the last session and two months later to assess for knowledge retention. Data were analyzed by SPSS version 20.
RESULTS
A comparison of the mean knowledge score of both groups showed that virtual learning was more effective than traditional learning (effect size = 0.69).
CONCLUSION
The newly designed virtual learning package is feasible and will result in more effective learning in comparison with lecture-based training. However further studies are needed to generalize the findings of this study.
背景
文献中讨论了在不同学科中使用电子学习等技术的重要性。研究人员已经在许多领域衡量了电子学习的有效性。考虑到在线学习在牙科教育中的有效性研究缺乏，特别是在伊朗，这些学习方法的优势以及对在线学习的积极的大学氛围。因此，本研究旨在比较两种教学方法（虚拟与传统）对学生学习的影响。
方法
本研究采用后测仅设计，涉及到来自 Shiraz 医科大学的 40 名五年级牙科学生。在这个群体中，有 35 名学生同意参与。这些学生被随机分配到两个组，实验组（虚拟学习）和对照组（传统学习）。为了确保组间的相似性，我们通过曼-惠特尼 U 检验比较了所有参与者的 GPA（P > 0.05）。实验组接受了专门为本研究设计的虚拟学习环境课件包，而对照组则以传统讲座形式接受了相同的模块。虚拟学习环境包括在线和离线材料。在最后一次课程结束后立即（15 分钟）和两个月后，进行了两次相同的有效、可靠的 40 道多项选择题（MCQs）和 4 道简答题的后测，以评估知识保留情况。数据采用 SPSS 20 版本进行分析。
结果
对两组平均知识得分的比较表明，虚拟学习比传统学习更有效（效果大小=0.69）。
结论
新设计的虚拟学习包是可行的，与基于讲座的培训相比，将导致更有效的学习。然而，需要进一步的研究来推广本研究的发现。
