Since 2016, The Research Group on Collaborative Spaces (RGCS) has started to organize collaborative learning expeditions. Later called OWEE (for Open Walked Event-Based Experimentations) these new research approaches based on open walk in the city follow the spirit of Open Science and Citizen Sciences. The OWEE workshop will be an opportunity to gather all people interested in collaborative learning expeditions and their use for education, managerial or political purposes. Beyond that, we will also discuss the issue of streets, public spaces, public social networks, open narratives and their use by researchers, entrepreneurs, managers and activits in the co-production of knowledge commons for the city.
