Uma proposta de ensino sobre a luz para o 9º ano do ensino fundamental: sua natureza, propagação e interação com a matéria

Abstract

In this dissertation, we present a teaching action in which both researcher and students try to innovate, taking as reference their day-by-day school practices. The researcher, with a regular performance as a Physics teacher in High School, launches the challenge of presenting the ninth graders from a public school, the knowledge that Light concepts can have a comprehensive and important application in our lives. As main theoretical references, the teacher embraces David Ausubel’s theory of Significant Learning , Levy Vygotsky’s SocioHistorical-Cultural Theory , and Paulo Freire’s liberating ideas , as well as contributions of Brazilian educational current legislation.in this work, we developed a didactic sequence, addressing qualitative aspects about the nature, propagation and interaction of Light with matter. For the researcher, who envisioned new directions and conceptions for his action as an educator, and for the students who were sharpened by contextual and meaningful knowledge, acting as effective partners in their status as students, this activity was highly rewarding. The sections in which content exposition, with experimental activities, interactivity, in addition to technological applications and its developments, were discussed and debated with curiosity, enthusiasm and longing for knowledge, were quite productive. The application of a questionnaire, seeking to achieve previous knowledge of the students, the brief researches developed by them in order to feel inserted in the research environment, were important for the elaboration of the didactic sequence. The educational product developed was the result of the active participation of the students. The important suggestions of colleagues and critical readers, and the enthusiasm of the researcher were a very rewarding educational opportunity. The work as a whole showed how important it is to look for alternative teaching strategies and methodologies, always taking into consideration the suggestions, interests, curiosities and knowledge incorporated by students in their daily lives.
