Virtual reality (VR) as computer-mediated 3-D environments including real-life situations presented via different tools in which users can interact effectively with visuals. This study is significant as it primarily aimed to investigate effects of VR on retention by comparing it with traditional 2-D videos. The main aim of this study is to compare the effect of VR and 2-D videos on learner retention and decision making. About 18 students from the Department of English language teaching in an age range of 18-20 (nine males and nine females) voluntarily participated in this study and took course credits. As all participants were tested under the same two conditions in different time periods; repeated measures were chosen for statistical analysis. It can be inferred that both technologies have similar effects on short-term retention and VR does not provide any extra retention performance. However, VR was found to have a significant effect on long-term retention.
