Acesso em:.https://repositorio.ufpa.br/jspui/handle/2011/17733Investigating the phenomenon of talk-in-interaction is a practice that has been expanding in research in the social sciences, linguistics, communication, psychology and education. In this scenario, Discursive Psychology (DP) emerges as a theoreticalmethodological perspective in the conception of the discursive phenomenon capable of contributing to the development of research in Mathematics Education. Interpretative repertoires and the Discursive Action Model (DAM) are concepts proposed by DP theorists that can connect different particularities that are present in the speeches of the participants in a systematic way, emphasizing the activities carried out by such particularities in the subjects' social practices. This research arose from the need to investigate the speeches-in-interaction that occur in the mathematics classroom taught by teachers without qualification to teach this discipline at school. The study aims to analyze the talk-in-interaction between teacher-students related to the interpretative repertoires and linguistic processes of action, fact and interest and responsibility that occur in the mathematics classroom. This is a study with 30 students from the 6th grade of middle school in a public school in the city of Imperatriz - MA and a pre-service teacher in the Natural Sciences Degree course at the Federal University of Maranhão (UFMA). The production of data was carried out in three stages: audiovisual recordings of mathematics classes, transcription of dialogues, coding and analysis of the talk-ininteraction. The results indicated the occurrence of didactic, pedagogical and arithmetic interpretative repertoires in the speeches of the teacher and students. Throughout the mathematics class, the teacher used the following discursive resources: attribution of advantage, technique of questions, inoculation of interests and role-play. Such resources represent an advance for the field of DP and Mathematics Education because they help to understand how teaching and learning situations related to arithmetic concepts are developed through the analysis of talk-in-interaction in the classroom.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Psicologia discursivaMatemática-Estudo e ensinoMatemática-Sala de aulaInteraçãoTeseCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICAETNOMATEMÁTICA, LINGUAGEM, CULTURA E MODELAGEM MATEMÁTICA
