There are several entities, individuals and organizations creating new resources in astronomy education. But these are scattered and and not created for a global audience. Also, when creating resources, educators tend to develop from scratch for many reasons: ownership, quality expectations, cultural adaptation, and I-know-best syndrome. In this talk, we present and discuss the creation of a “Cooperative” as a model for the co-development, production, and distribution of astronomy educational resources. We use the Universe in a Box project as a case study.
