这项工作首次阐述了对在一个为教授数字取证(DF)概念而创建的虚拟现实(VR)体验中的学习情况进行评估,以及在使用数字设备对犯罪现场进行标记与分类的实践实验室练习中的学习评估。首先,我们设计并开发了一种沉浸式VR体验,其中包括一场讲座和一个实验室。接下来,我们在一项对照实验中让(n = 57)名参与者对其进行测试,参与者被随机分配到VR组或实体组。两组都接受相同的讲座和实验室练习,但一组是在VR环境中,另一组是在现实世界中。我们收集了测试前和测试后的结果,以评估参与者对所学DF概念的知识掌握情况。我们的实验结果表明,沉浸式VR组和实体组之间的分数没有显著差异。然而,我们的结果显示参与者在VR环境中完成任务的时间更快,这暗示VR更具时间效率,因为虚拟环境可以通过编程快速搭建,几乎没有停机时间。
This work presents the first account of evaluating learning inside a VR experience created to teach Digital Forensics (DF) concepts, and a hands-on laboratory exercise in Bagging & Tagging a crime scene with digital devices. First, we designed and developed an immersive VR experience which included a lecture and a lab. Next, we tested it with (n = 57) participants in a controlled experiment where they were randomly assigned to a VR group or a physical group. Both groups were subjected to the same lecture and lab, but one was in VR and the other was in the real world. We collected pre- and post-test results to assess the participants’ knowledge in DF concepts learned. Our experimental results indicated no significant differences in scores between the immersive VR group and the physical group. However, our results showed faster completion times in VR by the participants, which hints at VR being more time efficient, as virtual environments can be spun programmatically with little downtime.
