A resolução de problemas como uma interface interdisciplinar entre a matemática e o ensino de ciências

Abstract

There are many challenges to the teaching of science and mathematics, particularly in an interdisciplinary perspective that enables the integration of objectives, methodologies and knowledge of the areas of natural science and mathematics. Understanding this difficulty, we seek to examine in this study the impact on teaching practice math teachers, continued formation focusing on problem solving as an interdisciplinary interface between mathematics and science teaching. For this, we count on the collaboration of teachers in the public school system of Rio Grande do Sul cities of Alegrete, Barra do Quaraí, Itaqui and Uruguaiana, who agreed to the training courses that made up this research. In the first stage of this study, we analyzes the concepts of 56 teachers, of the above sample, about the interdisciplinarity, from statements of pros and cons, written for them, about this approach. Qualitatively analyzed these statements, grounded in the methodology of discursive textual analysis. We identified misconceptions or presenting epistemological gaps, these shortcomings lead teachers to have fear of using interdisciplinary approach, either because they feel that the area of mathematics is isolated from the others, or because they believe that using this approach would result in the devaluation of mathematical knowledge, leaving to teach "important" content of mathematics. The second part of this study is the result of continued formation meetings, structured according to the three pedagogical moments of Delizoicov. We analyze the change in the frequency with which teachers use the problem-solving methodology and his views on the methodology. Therefore, we applied a questionnaire before the training course and the reaplicamos one year after this training. We found that the frequency with which teachers used the methodology of problem solving was increased in the questionnaire one year after stroke. We attribute this increase to conceptual change teachers on the problem-solving methodology, especially for passing to understand this methodology by an optical Ausubel significant learning. Finally, we see the potential of continuing education in the context of interdisciplinarity to improve the use of problem-solving methodology, it is possible to infer that this methodology has to be understood from the perspective of interdisciplinarity by teachers.
