Deliverable 4.1 provides a roadmap of activities for the seven national hubs of the project. These hubs, called Rethinkerspaces, will generate a deep and wide overview of ‘their’ national science communication landscape and act as testbeds and validation mechanisms for the research results of the project. Via their local communities, the Rethinkerspaces will be in charge of creating communities of inquiry to acquire insights into the emerging science communication landscape, map networks, actors, roles and repertoires, contribute to understand sensemaking practices and test a new quality of interactions framework. Besides, they will experiment with new strategies and train other actors in new ways of science communication. The Rethinkerspaces, based in seven European countries (Italy (ZML), the Netherlands (VU), Poland (CSC), Portugal (ITQB NOVA), Serbia (CPN), Sweden (V&A) and the United Kingdom (UWE), will become a learning environment to engage in a collective process of inquiry, experimentation and reflective learning.
