Ondas sonoras: uma experiência de ensino a partir de atividades experimentais investigativas

Abstract

Teaching-learning is a process that has always been present, whether directly or indirectly in relationships between humans. The good development of this relationship will depend on a good dialogue and the use of didactic resources by the teacher. Innovative activities and the use of experiments as a teaching strategy have been defended in the teaching of Physics for some decades, mainly as a possibility to arouse the curiosity and the consequent interest of the student. This research aimed to analyze the possibilities and limitations of investigative experimental activities in the understanding of sound phenomena, sound waves and physical properties of sound. The interventions were carried out in a high school classroom in the public network of the State of Pernambuco and organized according to Vygotsky's assumptions based on the idea that the human being is constituted as such, when it relates to the others and that this development is produced by the process of internalization of social interaction. This was a qualitative research that used different techniques of information and data collection: participant observation, interview, and questionnaires. As a product of this experience, a didactic material was elaborated that could serve as a parameter for teachers and students of basic education in new learning experiences.
