This document discusses how to build a sustainable innovation ecosystem for game-based learning in K-12 education. It argues that current game-based learning products have not achieved critical mass due to problems with deployment and a lack of an innovation ecosystem. It advocates targeting areas of non-consumption for pilots and disruptive implementation strategies. It also stresses the need to intrinsically motivate students by satisfying psychological needs, and notes that solely relying on government funding will not sustain the ecosystem long-term. A new collaborative model is needed involving multiple stakeholders from government, industry, and education.
