Pervasive games have been proposed as a suitable way to support learning, especially in places rich in information, as for example museums and cultural heritage sites. This paper reports on the work performed to identify guidelines that help designers in developing games able to provide an effective learning experience in such contexts. Such guidelines(More)
This paper describes a preliminary study where a multiplayer location based game's logfiles were used for the assessment of the overall practice of teams. We explore the use of activity metrics previously introduced and applied to CSCL settings. We argue that these metrics, if adapted in a meaningful way, will provide insight of the progress of a(More)
