This monographic study from the Pedagogy course seeks to understand teacher-student interaction in the context of the use of Internet social networks in a public high school. Special attention is paid to the process of reciprocal learning. To this end, the case study was carried out at Colégio Estadual Brigadeiro Schorcht (CEBS), located in the Jacarepaguá region, in the city of Rio de Janeiro/Brazil. The data produced from this case study cannot be generalized, but it can serve as an important reference to help in the analysis and reflection on the contexts of the use of information technologies that reconfigure school spaces and the teacher-student relationship. With the resources made available by cyberspace, Information and Communication Technologies (ICTs) and their constant presence in everyday social and school life, educators and learners have taken on a collaborative role in Internet social networks. Internet social networks are open to new possibilities and new uses.
