Learning networks do not arise from nothing. They are born out of personal connections, exchanged conversations, constructed spaces, and shared visions. Other broader contexts (e.g., the theoretical contexts or funding policies available within a globalized economy) are also part of this landscape. The Museum Mediators in Europe course is one of such learning networks that came to be in 2013 with the aim of representing institutional and professional needs of mediation professionals in the European countries involved in this project: Portugal, Spain, Italy, Denmark, and Estonia. The project argues that a clearly defined set of best practices in museum education is called for and that leadership/mentoring programs for museum mediators should be utilized to foster professional learning communities within museums.
