Um olhar investigativo sobre as interpretações gráficas dos protagonistas de uma sala de aula de Geometria Analítica An investigative look on the protagonists graphic interpretations of a classroom Analytic Geometry

This investigation is part of a larger study where we analyzed the way how students and professor, who study and teachers classes of analytic geometry, respectively, in a group of Mathematics Undergraduate students at the State University of Feira de Santana/BA, conceive aspects related acquisition, construction and interpretation of senses or meanings, produced or exposed in the classroom. To this, a research is carried out supported on the ethnographical practice from the proposal and argument that an environment is constituted in a multicultural cognitive universe or even in a micro-society, rich in production of meanings. This way, it is used observations in which the researcher places herself in a strangement position and quest for impartiality. The experiences are brought, through the emphasis or selection of characteristic episodes of involved performers’ (professor-students) way of meaning. The combination between algebraic and graphic language and semiotic studies are presented in all study construction as a method to obtain valid solutions and description of meaning processes.
