This article presents findings from a work with oral exposition genre in an adult education class in Caxias do Sul - RS, Brazil. Our purpose in this study is to help students to increase their oral genre repertoire and give support to teachers to elaborate a systematic pedagogical work, a Didactic Sequence, for the learning of oral exposition genre. We have also included oral exposition in the group of genres that can be studied for the implementation of a school radio in order to develop a good performance in that discursive sphere. This study is part of the action research project Medias and School: literacies and textual genres and follows the steps: action, problematization, reflection, action, and transformation.
