Today, the internet is one of the most accessible means of disseminating messages and, as a result, its language has spread and become globalised. Facebook, a social network that can provide deaf students with the opportunity to present their ideas, conduct online discussions and collaborate effectively in the learning of Portuguese language teaching through the use of contemporary digital technologies, is also part of this context. Thus, this research aims to contribute to measuring some aspects of the dynamics of inclusion of deaf students through the use of Facebook. The use of this social network is presented as one of the possibilities that can contribute to digital literacy and, more specifically, to the reading and writing practices of the target audience. The specific objective was to present these mechanisms as an ally for educators in the various classrooms in this country. Given all this, it can be said that the interaction established through Facebook shortens distances, transposes barriers and inaugurates a totally new way of establishing communication between internet users in cyberspace.
