In this paper we present a collaborative research experience in Science Education between teachers of different educative levels. Specifically, we analyze the mechanisms which took place during group and project work by the participants. From a theoretical point of view we were guided by the teacher's education studies and the systematization of action-research experiences. Methodologically, we have chosen the narration of scenes and their analysis to introduce the obtained categories (negotiations, scenes, objects and subjects, of negotiations, attitudes and strategies) and the discussions the group had about them. Finally, we present a reflection about our own learning through this experience and its analysis, towards a new "mise-en scène".
