Virtual reality applications in education are becoming more and more frequent. Empirical, data-based insights in the mechanisms and impacts of VR trainings are still sparse, however. With this quasi-experimental investigation, we compare the effects of a VR training game with a conventional face-to-face presence workshop in the field of vocational training. The training domain is awareness and customer interaction training for bank clerks. The results show that the VR solutions excelled the expectations of participants and the learning motivation was significantly higher as opposed to the conventional training. In the perceived effectiveness, the VR conditions achieved equal results than face-to-face workshops. The results provide evidence that VR solutions are an appropriate approach for vocational training.
