RESUMO

The purpose of this dissertation is to investigate the dynamic of meaning production for continuous function of one variable by graduate students in a calculus course. The framework articulates three theories. Conceptual metaphor as proposed by LAKOFF and NÚÑEZ, the importance of argumentation as proposed by FRANT and CASTRO in the model of argumentative strategies and, the definition of meaning production as proposed by LINS in the model of semantic fields. It is a case study research that happened in São Paulo, Brazil. The lessons were videotaped; it included ten students and their professor. Data collection consisted in videotapes, transcripts, notes from observation, students written material and, interviews. The results revealed that in a classroom meaning production for mathematics maybe not dependent of mathematics itself; authority of a professor or a peer plays a fundamental role. During classroom interactions, students used a every day language to communicate rather than a formal mathematical one. An enunciation, written or oral, does not guarantee the same reading, each reader has hers/his own interpretation. This study allowed us to better understand how students used their daily experience, embodied and mostly unconscious, to produce meaning for abstract concepts in Mathematics
