Gênero textual gráficos nos LD de matemática: a busca por seu perfil

Abstract

In this work, we are interested in investigating the way the graphic textual genre is presented in the textbooks of Mathematics (in a specific collection). Through this research, the focus is to understand whether the teaching genre is based on a vision inthatit is the vehicle of communication, or whether it is worked as a content of statistical bases. Knowing that the school is one of the spaces where many textual genres are known, we seek to analyze whether the graphs in the LD's of Mathematics, its teaching fits in the standards placed previously, following the studies of Sousa (2013), or if there is the presentation of it in other standards. Through the view of Marcuschi (2003) and other authors, in thatall textual genres are communicative supports, thatconstitute communicative actions, in use of the speakers to act in the world and on it, we use a methodology, which sought to understand the how the teaching of graphics is constituted, starting from analyzes in all the books of the collection, in search of a possible conclusion about our objective. Based on qualitative analyzes, we analyzed each example of the graphics contained in the "Araribá Matemática Project -2014" collection, which were delivered by PNLD for use in 2017, 2018 and 2019. Accordingto the National Plan of the Didactic Book, the collection presents interaction among the students, butithas a very great information content, making difficult in some aspects the learning of concepts brought. The need to understand how students study and use the chart in schools is important. It is a very representative genre in society and for this reason its form and function must be known and recognized by all who use it or not, to communicate. Considering the difficulty of finding studies on the graphs, only Sousa (2013), our research has been able to perceive that the representativeness of the genre in focus, is strongly based on the opposite patterns of the function that every textual genre plays in society.
