A importância da experimentação no ensino de física para alunos do 2º ano do ensino médio

Abstract

This paper discusses the role of experimentation in teaching Physics and through theoretical contributions, emphasizes the importance of this methodology in the teaching-learning process. From an interview with teachers of physical, coordination and school towards the main difficulties in conducting practical classes were raised. In order to ascertain student learning through this methodology and preparation of materials that could be used by teachers in other classes were developed with students of the 2nd year of high school, some experimental activities such as bimetallic strip (thermostat) Gravezande ring (key and lock), Mini Air Conditioning, driving the heat through a metal bar, irradiation Heat in a Incandescent lamp, Thermal Machine and Machine Steam (Thermal Power Plant). All experiments were made using recycled materials and / or low-cost involving thermal physics content. On student participation in the development of experimental classes, this work, which showed curiosity and enthusiasm in carrying out all the steps of the proposed activity, it is observed that the lessons have become more interesting, easy to understand, enabling a relevant learning, both in the discipline in question, as in other, related to the science of nature, since the studied subjects addressed interdisciplinarity.
