This study aims at investigating how learning strategies instruction may enhance the development of oral production. Instruments used to conduct this case study were field notes, questionnaires, interviews and class audio recordings. Seven female third level undergraduate students of the Curso de Letras of the Federal University of Pará were the subjects of this study. Since the oral production is the main concern of most foreign language learners, this investigation aims at contributing to a better understanding of this issue by suggesting that the explicit learning strategies teaching may conduct to more satisfactory outcomes. Results showed that there were changes in the learning strategies repertoire used by participants.
