This paper and accompanying poster describes the design of an intrinsically integrated educational game to improve children’s competencies in mental mathematics. A number of researchers have suggested that educational games are more effective when they are closely integrated with their learning content. Specifically work by the lead author has showed that a closer integration between an educational game's core-mechanics and its learning content can be both more appealing (in terms of time spent on-task) and more educationally effective (in terms of learning outcomes) than a less integrated "edutainment" approach. However, cursory approaches to integrating learning content remain common in contemporary educational software, and the literature lacks an exemplar of what can be achieved using an integrated approach. The Outnumb3r3d game was conceived to provide a commercial and theoretical exemplar of intrinsic integration for the Nintendo Wii, but was never completed. This project is now porting the original Wii prototype onto the PlayStation 4 in order to revive Outnumb3r3d as a research project.
This paper details the design of Outnumb3r3d with reference to the key theoretical constructs that underlie its pedagogical design. In doing so it provides an example of a game design created to integrate mathematical learning content seamlessly into the game's core mechanics, ensuring that the mathematics is what makes the game intrinsically motivating to play rather than trying to hide or "sugar coat" its learning content. At the time of writing the game’s implementation is still a “work in progress”, but is expected to be the subject of future empirical evaluations into its effectiveness as a teaching tool
