Generative AI as a Learning Partner: Structural Insights from a VR–GPT Educational Platform
摘要
Virtual reality (VR) enhanced by Generative AI (GenAI) avatars offers opportunities for adaptive and engaging educational experiences. While prior studies emphasize the roles of performance expectancy (PE) and technological efficacy (TE) in learner engagement, few examined how AI scaffolding influences metacognition (META), agency, and motivational beliefs in VR. This study applied structural equation modeling (SEM) to investigate these dynamics in two experimental groups in low-immersive VR (desktops). The model demonstrated acceptable fit (CFI = 0.912, TLI = 0.887) and R \(^{2}\) values were highest for intention and technological efficacy (both > 0.70), with metacognition at 0.491. PE predicted both intention to continue using the system and TE, while GPT interaction increased META. However, META negatively predicted PE, suggesting a trade-off between reflection and system use. These results highlight the importance of designing AI scaffolding that supports metacognitive processes without undermining motivation. Integrating AI within VR environments can better align with learner expectations and improve both engagement and learning outcomes.
