Traditional Business Process Model and Notation (BPMN) diagrams, being static and highly abstract, often hinder comprehension, particularly for novice designers and students. This can lead to misinterpretations and process inefficiencies. In this study, we investigate whether immersive three-dimensional (3D) virtual environments can enhance the understanding of BPMN models. We developed a virtual reality (VR)-based BPMN visualization tool and conducted a quasi-experiment with 48 academic and professional participants, who interacted with a 3D BPMN model using Google Cardboard and a joystick. Participants completed comprehension tasks before and after the VR experience. The results show significant improvements in understanding and engagement, suggesting that immersive virtual reality can be a valuable educational tool for BPMN learning. This study contributes empirical evidence supporting the integration of 3D environments in process modeling education, offering benefits for both academic and professional training.
