Students in housing economics often find concepts like loans, liquidity, and interest rates challenging due to their abstract nature and limited real-world connections. Authentic, immersive approaches, especially those that simulate real-world scenarios—are essential to foster an intuitive understanding of economic principles in housing. Self-regulated learning encourages active, goal-driven learning processes that can make these concepts more accessible and engaging. Traditional methods like classroom-based or mobile-based learning lack the depth and interactivity needed for complex housing economics training, such as mortgage advisor, where realistic buy/sell interactions are essential. The use of virtual worlds to simulate a game-based, self-regulated environment with student-generated content remains largely unexplored, particularly in housing economics education. This project aims to use the HomeWise Center, a virtual mortgage simulation, to develop core competencies in financial literacy, negotiation, and decision-making within housing economics with peers. Through real-world scenarios, students will gain hands-on experience with concepts like loan risks, budgets and liquidity. Unlike traditional classroom methods, that rely on theoretical or lecture-based instruction, the immersive nature of HomeWise Center will help students actively apply these concepts in realistic settings, fostering deeper understanding and retention of learning outcomes. In HomeWise Center, students engage in buyer/seller roleplay with 5 unique generative AI-powered avatars simulating customer service agents. These avatars provide real-time, tailored feedback, allowing students to immediately reflect on and adjust their strategies. Students are assigned buyer or seller personas with specific financial backgrounds and requirements, allowing them to set goals, strategize, and make purchasing or selling decisions in a structured, three-round simulation. Through game-based scenarios and real-time feedback from AI avatars, students actively apply housing economics concepts, gaining practical skills, confidence, and an authentic understanding of economic principles. This model provides transferable templates for other disciplines, such as sustainability – to be implemented in a waste audit module in Science Unit and expanding upon existing virtual worlds in the Department of English of Hong Kong Polytechnic University, expanding cross-disciplinary adoption and institutional impact.
