Contribuições de uma prática docente interdisciplinar à matemática do ensino médio

Abstract

The theme of this research was the analysis of the interdisciplinary academic practice bound to the high school level mathematics. Its objective was to identify the theoretical assumptions of the interdisciplinarities subjacent to the day-to-day life of a mathematics teacher when teaching the subject Functions, to students of the first grade in high school. In the teacher s memories present on her records, class plans and grades, the work developed gains a perspective that understands the interdisciplinarity as a new attitude towards knowledge, while the curriculum guidance is restricted to the interdisciplinarity as an integration of the several disciplines of the school curriculum. Thus, the differentiated behavior of that teacher, intuitively permeated by the interdisciplinary academic practice aspect, went beyond the prescribed indications of the existing legislation. Under the qualitative research methodologic guidance, focusing the history of life, and in the report on autobiographic journals, allied to the interdisciplinary research that motivates the teacher on researching her own practice, the professional, now researcher of her own school day-to-day, went through three trajectories (personal, professional and academic) to demonstrate the theoretical principles in her academic attitude. In order to achieve that, the thesis presents a wide bibliographic tracking to address the theme s pertinence, followed by a revision of the area that utilizes the historic line as a conducive thread to prove the cyclic movements through which the curricular guidance conveyed the mathematics teaching and that influenced the academic practices of that school discipline. She also states that, when proposing Project Function and the Beanstalk, the approach of the specific contents occurred under the fusionist focus which tries to relate the algebraic with the geometric axle, in addition to insert the theme into a context. Lastly, it concludes that the teacher, when developing that practice in a classroom, addressed the specific theme of her working area, in her case, mathematics, under the perspective of interdisciplinarity taken as a new attitude vis-à-vis the knowledge conducing the educator far beyond the boundaries that his disciplinary formation imposes
