"Virtual reality" adds a new dimension to problem-based learning (PBL) environments in the architecture and building construction educations, where a realistic and lifelike presence in a building enables students to assess and discuss how the various solutions interact with each other. Combined with "Building Information Models" (BIM), "Virtual Reality" provides an entirely new opportunity to innovate and optimize architecture and construction in its early stages, which creates an iterative learning process. The analysis identifies several clear opportunities regarding extended use and involvement of the gamification mechanisms known from, e.g., video games software--like the principles behind quest, levels, dungeons, etc.--to support web 2.0 features in the future development of VR systems. The study clarifies the challenges of creating web 2.0 solutions with the complexity and robustness that supports a sketching, design-oriented, exploratory and investigative learning process, which is at the core of problem-based learning.
