O ENSINO DE FÍSICA NO ENSINO MÉDIO: DESCREVENDO UM EXPERIMENTO DIDÁTICO NA PERSPECTIVA HISTÓRICOCULTURAL

Abstract

This study describes a methodological experience in Physics teaching with the objective of trying, through a didactical-formative experiment, a differentiated methodology focused on the formation of theoretical-scientific thought and that aims to evaluate the didactical actions of a teacher, derived from a teaching plan, in relation to the formation of mental actions of his/her students. The interest towards the research theme arose from the observation of an existing lack of motivation from students to study Physics and the challenges faced by the tutor while teaching that subject. The historical-cultural theory by Vygotsky was adopted as a theoretical-methodological reference and, within it, the developmental teaching theory by Davídov, due to its great potential to contribute to the improvement of Physics teaching. These theories aid the teacher in planning and developing his/her work as they propose the organization of teaching focused on the formation of concepts, the connection between content analysis and student's motives, and also the organization of interaction situations and mutual collaboration to nurture the development of mental actions. A qualitative research was made while applying the didactical-formative experiment, which is a procedure that allows monitoring the process of mental action formation throughout the execution of a teaching plan. The experiment consisted of planning, by researcher and teacher together, content and learning strategies for a teaching trimester to the sophomore year of the Mechanical Physics class. That class is part of the Integrated Construction course of the Instituto Federal de Educação Tecnológica do Estado de Goiás, former CEFET-GO. Data obtained from observations suggest an improvement on the interest and learning levels from students, showing the relevance of a differentiated Physics teaching methodology, which emphasizes the formation of and acting with concepts. They also point to the relevance of theoretical and methodological formation of the teacher, and the necessity that he/she considers, in teaching practice, the impact of his/her own epistemological conception towards the teaching and learning process.
