The aim of this study was to get to know the perceptions of family members and professionals about the use of Facebook by the staff from the Espaços de Desenvolvimento Infantil (Spaces of Child Development) in the city of Rio de Janeiro. This objective arose from an old issue, but still very present in the work with children ages between 0 and 5 years and 11 months, which refers to the communication between families and Early Childhood Education professionals. The practice of sharing pedagogical records on social network grew at a time when access to the internet became popular and also it provides a quick way for families to have access to the work that is documented by the institutions. It is understood that this practice plays a role in the dialogue between family and school and that it gives access to part of what is planned and experienced in it. Focus is given to the way that Facebook is used by the school professionals: their goals, their choices and the feedback they receive and / or expect to receive from parents. More specifically, we sought to a) identify the purposes surrounding the decision to use Facebook, by teachers, management, and other professionals involved; b) understand the organizational criteria they adopt when using Facebook and how it involves professionals, families and children; and c) know the aspects that prove to be important in daily life and that are worthy of being broadcast on social networks. As a theoretical contribution, studies were adopted that cover the relationship between family and school, the use of new communication technologies in this relationship and discussions that underlie the practices of Early Childhood Education. The research was carried out in three Child Development Spaces (EDI), with the management team of each unit (two directors and an articulating teacher), eleven leading teachers and nine family members of enrolled children. The study methodology included the following instruments: (i) a survey of the use of Facebook; (ii) a questionnaire on the use of social networks; (iii) an online interview with school professionals; (iv) an online interview with family members; (v) samples of postings on Facebook. The interviews took place between the months of June and October in 2020. The data were processed through thematic analysis carried out with the support of the ATLAS.ti software. Three axes of discussion were built, namely, the purposes of using Facebook, organized management and the perceived reverberations. The results showed that professionals and family members use Facebook as support for the dialogue between EDI and families, as well as for the knowledge construction of the pedagogical proposal of Early Childhood Education in its specificities.
