Gamification- and Virtual Reality-Based Learning Environment for UML Class Diagram Modeling

In the realm of conceptual and system design, mod-eling stands out as a pivotal activity, emphasizing the significance of mastering modeling languages such as the Unified Modeling Language (UML). Despite the existence of numerous interactive UML learning applications and the emergence of gamification-based alternatives designed to enhance learner engagement, a gap persists in providing an immersive learning environment ca-pable of significantly increasing interactivity during the learning process. Current approaches fall short in creating a sense of presence that could positively impact learning outcomes, and the full potential of gamification remains underexplored. To address this gap, this paper introduces an innovative so-lution-a gamification-based UML learning environment within Virtual Reality (VR), named GaMo Vr.This immersive platform is specifically tailored for practicing the creation of class diagrams in an interactive manner, incorporating mini games to support the learning process. The study conducted to evaluate GaMo Vrinvolved 16 participants and utilized the MEEGA360 question-naire. In comparison to a similar desktop application, the results of the evaluation revealed that GaMo Vrsignificantly enhanced learners' motivation, enjoyment, and engagement, along with a perceivable improvement in the overall learning outcome. This groundbreaking approach not only bridges the existing gap in UML learning applications but also harnesses the potential of VR and gamification to revolutionize the way modeling is taught and learned.
