Teaching the assembly of prefabricated housing requires mastering both procedural sequencing and spatial understanding to position and connect structural components accurately. This paper evaluates a guided immersive Virtual Reality (VR) workflow designed to simulate the structural assembly of a prefabricated house as a safe, repeatable learning activity. In a single-session pilot with n=12 construction graduate students, participants completed the VR assembly training task and responded to a post-experience questionnaire (Likert 1-7) along with open-ended questions. At the same time, the VR software automatically logged objective performance indicators (time, attempts, successes/errors, accuracy, and efficiency). Survey results showed consistently high ratings across usability/conditions, perceived learning, and transfer intention (an overall rating of 6.25 out of 7). Software logs indicated an average completion time of 10.69 ± 2.65 minutes and a mean accuracy of 0.61 ± 0.18, with significant variability in error-driven rework (ranging from 3 to 40), suggesting diverse execution strategies. Correlation analyses confirmed strong internal links among objective metrics (e.g., accuracy vs. errors/min, ρ=-0.984), while perception-performance associations were generally weak; notably, perceived learning increased with time/attempts and decreased with accuracy/efficiency, suggesting a “productive struggle” pattern during early exposure. Qualitative feedback emphasized improvements in room-scale safety, practice recurrence, and task complexity. Overall, the study offers a replicable triangulation framework that advances VR construction-process education from satisfaction-based assessment to measurable procedural performance and practical design improvements.
