Potential mechanisms behind the findings
Aside from the possibility of a chance finding, we suggest five possible mechanisms to explain the superior effect and likability of desktop VR found in this study.The first is automated individual feedback. A VR application, like the one in this study, can be programmed to provide instant feedback. Feedback on performance is crucial to learning and can be enhanced by timely, specific, and learner-targeted feedback [The second mechanism is that in a virtual environment, players are represented by avatars, which can create a sense of anonymity that can increase enjoyment of the experience [The third suggested mechanism is related to how information is provided during the simulation. The use of visual instructions as a tool for learning has been investigated in several studies, and it has been found that both visual appearance of educational content in VR [The fourth mechanism is automatic guidance supporting progression during practice. Automatic guidance in VR can exert both positive and negative effects on learning, depending on the context and the type of guidance provided [The fifth and final mechanism that we suggest is repetition. A notable finding in this study and others [
