This presentation focuses on the possibilities and challenges of developing "collaboration modes of convivencia" between schools and families in vulnerable areas in Mexico, reflecting on the role educational research might play in fostering them. It derives from a doctoral research that analyzed the relationships between two Mexican public primary schools and their local communities and their implications for school convivencia (the experience of living together and learning to live together in schools). The paper firstly explains the concept of school convivencia and the restrictive and comprehensive approaches used to understand and intervene it. Secondly, it addresses the research aims, data collection and analysis carried out from an ethnographic perspective. Thirdly, the results section presents a summary of four modes of convivencia developed through the research: alliance, confrontation, detachment and collaboration. The significance of these modes is then discussed, focusing on the importance of the collaboration mode for transforming school convivencia and identifying the elements that make it possible and that limit it. Finally, the paper critically analysis the role of ethnographic research to foster this mode and the transformation of school convivencia.
