The purpose of this research is to investigate the affordances and constraints of developing 3D teaching vignettes for effective case-based learning. It is built on the paradigm of case-based learning, which enhances higher-order thinking abilities. Sparse research explores both students’ engagement and learning outcomes via three-dimensional (3D) teaching vignettes or 3D cases. In this study, a quasi-experimental study confirms the authors’ earlier finding that learners overwhelmingly prefer 3D to text-based case studies. A paired samples t-test shows students demonstrate significant cognitive gains when studying a new domain subject via a 3D case study. In this paper, the authors describe a design-based research process of developing 3D case studies that capitalizes the affordances of 3D technologies. An in-depth discussion of important issues such as limitations and lessons learned is also included to explore the pragmatics of using 3D technologies to promote learning.
