This chapter illustrate how the social and material arrangements for interprofessional simulation produces different conditions for learning. The first section focuses on the emerging medical knowing, affective knowing and communicative knowing in the socio-material arrangements of three locations involved in the simulation, i.e. the simulation room, the observation room and the reflection room, during the course of events in the scenario. The second section focuses on emerging rhythms of collaboration. Different ways of relating to the manikin as a technical, medical and human body, and the relevance of these findings for simulation pedagogy are described.
