Experimentos demonstrativos e ensino de física: uma experiência na sala de aula

Abstract

The search for the better understanding about the use of experimental activities during the expositive classes and the identification of a appropriate dynamics discourse this teaching practice have been the subject of several researches, discussions and analysis in order to provide the most meaning and attractive Physics teaching. In this research work we investigate, we investigate if the teaching strategy based on the application of experimental demonstration activities in the classroom, in the perspective of the Vygotsky‟s sociocultural theory, makes possible the social interaction of students with teacher and students together, in order to contribute to knowledge construction and reframing of teaching and learning of physics. In this sense, we focus our analysis on the discourses that occur around these activities. Teacher and students of the second year of high school of the State School in the city of Serra Branca‟s city in Paraiba make up the universe of this study, where we use a qualitative methodology, type Case Study, taking as research instrument the free observation in the natural environment of the classroom and a semi-structured interview with the teacher. To facilitate the transcription of the dialogues occurred in the classroom as auxiliary resource, use audio and video recordings.
