Elaboração, aplicação e validação de uma sequência didática à luz do Modelo das Múltiplas Perspectivas – Pernambuco (MoMuP-PE) para a construção de conceitos Bioquímicos

Abstract

The teaching-learning process of Biochemistry comes up against some difficulties, which can be attributed to the need for a systemic view about its themes, which permeate between a macro and microuniverse. In an attempt investigate an enabling strategy for the construction of biochemical concepts, we seek to develop, implement and validate a Teaching Sequence (SD), based on theoretical assumptions established by the Model of Multiple PerspectivesPernambuco (MoMuP-PE), bringing aspects of food as problematizing context. In the present research, the SD built, was applied in a class of the technical course in Agropecuária integrated to the High School linked to the Agricultural College Dom Augustinho Ikas (CODAI / UFRPE), within the scope of a school intervention linked to an institutional extension project. The purpose of this research was to guide the planned actions involving the construction of concepts involving energetic metabolism, predicted in High School, working the composition of food within a chemical and biological universe, being these articulated to the concept of health and society. From the analysis of the questionnaires applied before and after the intervention, as well as the activities produced during the SD, it was possible to validate the proposed SD, in view of the conceptual re-elaborations carried out by the students and the articulations involving the micro and macro nutrients, the process feed, and the factors which interfere with building a healthy eating habit. In this sense, the theoreticalmethodological assumptions of MoMuP-PE guided the construction of the actions present in the SD developed, so that, from these orientations present in the proposed actions, allowed the students to experience, in an initial study perspective, activities of deconstruction and reconstructions (mental and materialized), leading them in the process of conceptual elaboration in a pragmatic and articulated perspective, permeating in this process, the thematic crossings observed throughout the activities.
