The imbrications between language activities and educational processes are, to a large extent, essential configurations for the studies presented in this book. In the first part, the book deals with a theoretical survey, the configuration of which underpins the dialogical-interactive perspective of language so that, in the second part of the book, it provides a referential basis for a comparative study between pedagogical proposals and mediated assessment. The work’s theoretical characterisation is made up of relevant studies in the field, whose approaches are based on Bakhtinian work [Bakhtin, Volochinov and the Circle], according to a dialogical perspective of language and its use (activity), based on verbal interaction, which is responsible for mediating between the subject and the world. Happy reading.
