Effectiveness of VR Training and Observer-Based Learning for Complex and High-Risk Construction Task Performance

초록

Effective training is crucial for mitigating construction accidents and enhancing worker performance during high-risk complex tasks. Virtual reality (VR) environments are increasingly recognized as offering safer, more effective, and more efficient training methods for preparing individuals for hazardous construction settings. This study examines the impact of VR training on learning and motivation in such tasks, focusing specifically on post-tensioning slab construction. This study compares three training methods: VR training, VR observer training, and traditional paper-based teaching. Data collection involved post-test quiz scores and ratings from the Intrinsic Motivation Inventory (IMI). Statistical analyses, including one-way analysis of variance, post hoc tests, and effect size calculations, were applied to the data. The results indicate that the VR user group achieved significantly higher post-test scores and demonstrated greater intrinsic motivation across most dimensions than did the traditional group. Effect-size analyses underscore the practical significance of these findings, suggesting that VR technology and observation methods can significantly enhance learning effectiveness and motivation in challenging and hazardous construction tasks. These findings have implications for educational strategies and instructional designs in occupational training contexts.
