Concepções de alunos do ensino médio sobre o tema água: subsídios para o planejamento de atividades investigativas interdisciplinares

Meaningful learning occurs when new knowledge to be aggregated are grounded in other students already possess. In preparing didactic sequences for teaching concepts, one should take into account these concepts and knowledge to produce more effective and lasting learning, and build new concepts that will become subsumes for subsequent learning. This research was developed in a subproject linked to institutional Scholarship Program Initiation to Teaching (PIBID) of a Universidade Estadual Paulista. The proposal is based on the articulation of the Public School and the University, strengthening the initial training of undergraduates, and continued teacher network, improving the quality of education. The proposed work is based on interdisciplinary research and teaching by investigation. Undergraduates in Biology, Physics, Mathematics and Chemistry jointly propose interdisciplinary teaching activities and investigative applied to high school students of Public School partner. To survey the views of these students on the theme Water, they were asked to draw up an essay entitled "The importance of water", with the aim of organizing information for planning a teaching strategy that articulates the disciplines of training of undergraduates. In this paper we present a qualitative analysis of these essays, performed based on content analysis. The analysis allowed to identify existing concepts in students' cognitive structure and classify them into adequate and inadequate compared to scientifically accepted concepts. Several misconceptions were raised indicating the need to produce didactic sequences that in addition to working the concepts presented in the curriculum of disciplines take into consideration the possibility of more meaningful learning. This research produced the elucidation of existing concepts, indicating where deficiencies were larger. One major contribution was the realization that concepts that may be considered by teachers as simple and already acquired by the students often come so misguided in their explanations. From the results obtained, integrated activities have been planned and implemented, and more relevant to the needs of students aiming to recover and enrich the knowledge they possessed, encouraging the use of scientific concepts and their application to daily living situations.

Representações de conteúdo inseridos no plano de ensino de professores em formação continuada

A partir de um curso com abordagem interdisciplinar contemplando as áreas: Química, Física e Ciências Biológicas, solicitou-se aos professores de Química a elaboração de Planos de Ensino, sobre o tema Equilíbrio Químico. O objetivo foi construir uma análise das representações de conteúdo (CoRe) no planejamento. A pesquisa realizada caracteriza-se como qualitativa descritiva e a análise foi realizada com base na análise de conteúdo. Inicialmente os professores apresentavam preocupação com relação à memorização dos conceitos pelos alunos. Ao final, pode-se perceber uma ligeira mudança no discurso dos professores e sua postura valoriza a compreensão dos conceitos relacionados ao conteúdo, e os conhecimentos prévios dos alunos como requisitos de aprendizagem.
