The aim of the present intervention research was analyzing methodological issues that cross the joint production of a work developed by the Museu de Favela (MUF – Slum Museum) in partnership with NIMESC/PUC-Rio, around the memories of women dwellers of the slums Pavão-Pavãozinho and Cantagalo, in Rio de Janeiro. Having as starting point the dialogs with authors who have adopted a social-historical and critical perspective of culture, a collaborative work was sought by means of a research done with the other. Thus, the Prêmio Mulheres Guerreiras (Warrior Women Award) was closely followed; it is an activity that MUF conducts every year and whose objective is to honor women who bear a social value for the favela . Memory interviews conducted by the museum with the 2012 candidates to the award were observed and from such observations a Training Course for Memory Listeners (Formação das Escutadoras de Memória) was implemented with MUF in 2013. Women dwellers of the abovementioned slums were invited to take part in this course with the purpose of sensitizing them with regards to the importance of the collective memory in the strengthening of the social identity of a community, and thus fomenting the desire to listen and (re)cognize the life histories. Several methodological aspects that cross a memory interview were discussed, as well as a way to provide materiality to the stories. The collective memories which stood out from the interviews carried out by the course participants were those related to the experiences that happened during the building of the community amidst the precarious infrastructure of the slum. Traumatic memories connected to violence also stood out, as well as those related to the experience of being a mother in the slum. The research has shown that this work of listening to memories might benefit from less oriented strategies, i.e. those that prioritize an interaction that is closer to a conversation and whose connection is based on empathy, instead of a preestablished interview script.
