Reading and production of mathematical inferences in the study of inequalities

Abstract

The goal of this research was to analyze the production of inferences in reading strategies involved solving mathematic problems. The approach of research was qualitative and it developed with students of at the end the elementary school in a multiserie class of the campesina region of the Santa Maria das Barreiras city, in state of Pará, using the sequences didactic as tool to production of data. The structure of activities consisted in to omit important mathematical informations of the text for make the students produces inferences based on reading. The results show that students had better performance in the problems that demand the production of elaboratives inferences - they complementary the sense and has the function of to extend and to complete the informations about the text - than in logical inferences - starting from of text’s explicit informations and are essential to the process of production of sense. The concluding is that the development of tasks on focused on a stimulating to inferential activity in context of textual interpretation in the mathematics’ classroom it’s promising to promote in the students the development a mathematical skills, like as to create, interpretation and switch over between many symbolic and graphic representations, to solve problems through inequalities, with comprehension about used procedures.
