Massive open online courses (MOOC) constitute an emerging technology for distance and open education while interest in incorporating them in higher education is constantly growing. Due to the free and open access learning opportunities that they offer, they attract an immense number of learners from all over the world. Additionally, because of their openness, they present major challenges, including network co-creation within communities and new forms of communication and collaboration for both students and educators. In this article, the authors present a methodology for a team-based development of MOOCs with the use of a recognized design model that they applied in Hellenic Open University. The main objective is to illustrate the lessons learnt during this MOOC development.
