Pensamento algébrico: indícios de um currículo enculturador

Abstract

In this work we present a qualitative research guided by the objective of investigating evidence of a enculturador curriculum evidenced by the prescribed curriculum, the curriculum presented and curriculum molded the state public network in the treatment of aspects related to algebraic thinking and investigate relations and not relations evidenced between enculturador curriculum and algebraic thinking in curriculum levels analyzed. Note that we do not consider that the drafters of these materials known or considered the enculturador curriculum in the writing of these materials, but we seek to identify the aspects of this type of curriculum that emerge in the treatment of aspects of algebraic thinking. For this purpose we conducted a content analysis, according to Bardin (2014), the prescribed curriculum and the curriculum presented to the state public network, and semi-structured interviews, second described by Ludke and Andre (2005), with thirteen teachers of the same school system, considering how theoretical framework for this analysis the aspects of algebraic thinking, described by Ponte, Branco e Matos (2009) and aspects of a curriculum aimed at a mathematical enculturation second Bishop (1999). Justify the importance of a curriculum targeting a mathematical enculturation, because working with the proposed aspects of this approach can help mitigate the problems detected in the way the math curriculum is being conducted, for example, linearity, accumulation, the practice of lettering, the curriculum directed to the development of techniques and impersonal learning. By analysis of the three indicators mentioned found that the item of hillside represent called read, understand and operate with symbols, using the usual algebraic conventions, and the item deduct of hillside reason, were predominant. Intercultural activities counting and measure were the most glimpsed. With regard to values we note that the objetismo, openness and progress, were the most highlighted. The principles of accessibility, conception wide and elementary and representativeness prevailed in the analyzed indicators. It is also worth mentioning that two principles of a enculturador curriculum were not treated with due attention, namely, the explanatory power and formalism. The item generalize, which is part of the reason shed, It was observed only in response to one of the teachers and in one of the volumes of the Teacher's Notebook prepared by the State Department of Education and considered in this thesis as the curriculum presented to teachers. We found in the analyzed indicators, the surface presence of intercultural activities to explain and play
