One possible context for intervention is the popular video game Minecraft. Minecraft encourages users to engage in spatial manipulation of 3D objects. However, few papers have chronicled any in-game practices that might evidence spatial reasoning, or how we might study its development through the game. In this paper, we report on 11 middle school students’ spatial reasoning practices while playing Minecraft. We use audio and video data of student gameplay to delineate five in-game practices that align with spatial reasoning. We expand on a student case study, to explicate these practices. The identified practices may be beneficial for studying spatial reasoning development in game-based environments and contribute to a growing body of research on ways games support development of important and transferable skills.
