Resumo: |
This work is a qualitative research that it has as purpose to investigate the students' of the 2nd year of the Medium Teaching of a state public school of São Paulo acting, on the interpretation and analysis of information contained in graphs. The study was inspired in the recovery Project and students' of the state public net reinforcement, "São Paulo Faz Escola", proposed by the General Office of Education of the State of São Paulo in the year of 2008. Specifically, we stopped in the material addressed to the students of 7th and 8th series, in the form of a newspaper, in which the block of Natural science suggests several activities, involving texts and graphs that treat of the growth certain quatis populations. The starting point of that proposal was discussion of the meaning of the alimentary chain related to the animal life of a certain area, culminating with the calculation of the taxes of rude and relative growth. We noticed that those activities with graphic representations, requested of the students mathematical abilities and reading capacity and interpretation of data contained in graphs, to solve them. We identified a good opportunity there to accomplish our work, seeking to investigate as the students behaves when requested to look for information contained in graphs, for they make comparisons of amounts and they manipulate knowledge mobilized of mathematics, in what it refers to the subtraction operations and division. The instrument for collection of data was constituted by five activities contentment texts and graphic representations, that you/they were orientated by the theory of the Registrations of Representations Semiotics of Duval, and for the levels of understanding of graphic representations, of Curcio. The students accomplished the activities in a climate of enthusiasm and seriousness and the results allow to infer that, with the worked abilities, the students seem to be instrumented to begin the analysis of the behavior of functions starting from it graphic registration. This conjecture can serve as starting point for future researches |
