Mobile technologies are increasingly rooted in society and, therefore, intuitively, teachers begin to take advantage of devices that students carry with them daily in a logic of 1:1 bring your own device (BYOD). In fact, it becomes crucial to use this media to promote/increase new pedagogical activities to motivate and challenge students to acquire and discover knowledge. This was the inspiration to create the MobiGeo, an Urban Game, for Geography teaching. The research question that guided the project was to understand whether the implementation of MobiGeo influence the process of learning geography in an outdoor education context. Data obtained allow the researchers to conclude that Urban Games are potential agents of motivation and interaction that predispose students to learn geography in informal learning environments. So, they suggest that the roles of teacher and student should not be abandoned but recycled and adapted to this new reality that requires more personalized and diverse activities of learning.
