Based on the explicit principles of connectivism (autonomy, diversity, openness and interactivity) and on the activities of aggregation, remixing, repurposing and feeding forward resources and learning, connectivist Massive Open Online Courses (c-MOOCs) have made a large impact in online education since 2008. Ideally a great part of c-MOOC participants should share, produce and consume digital media. But this does not happen and a majority of learners stay on the side as silent participants that only consume (lurkers). Those active never exceed 10% of those registered. The way c-MOOCs have been delivered up to date can be divided into: i) those that make use of a daily newsletter used by the facilitator to syndicate fundamentally the blog posts from the active participants and ii) those that rely on a centralizing web page and where all course discussions happen via the usage of a mailing list. In each format participants undergo a very different learning experience but the relation active-to-lurker is in both ve similar. After the success of MobiMOOC 2011, Inge de Waard organized and coordinated in September 2012 a three weeks course on mobile learning. MobiMOOC 2012 relied on a format of a centralized wiki and mailing list but introduced a new delivery structure: a tree arquitecture. Participants concentrated in only one topic in the first week, four were offered on the second and eight on the third. MobiMOOC 2012 and this experimental new organizational structure are described in detail in this paper. We particularly analyze if a more balanced distribution of participants in active and lurkers roles was achieved when compared to previous experiences.
