Uma Proposta de Alfabetização Científica e Tecnológica Sobre Nanoestruturas em Cosméticos

Abstract

This study aims to propose, implement and evaluate a didactic-pedagogical sequence guided by scientific and technological education on nanotechnology of cosmetic products for technical teaching in Aesthetics. The Theory of Developmental Teaching was added to this work, which aims at both social interaction and the development of content and thought processes and strategies, and the application of tasks, together with the approach in Science, Technology and Society mediated by the Controversy Controlled, with the intention of building strategies that encourage the student to think, generating a process of awareness about the use of nanocosmetics. Four activities were developed divided into different moments, totaling 20 hours of class. We opted for a research with a qualitative methodological approach of a descriptive nature, developed in a technical school located in the Campanha region in Rio Grande do Sul. Data collection took place through the application of questionnaires, filming, audio reports from the researcher professor, discussions with students, photographs, written records and the construction of study materials. The data were gathered and analyzed in an attempt to approach discursive textual analysis. The results obtained indicate that the activities developed through the didactic intervention, contributed to the construction of knowledge and citizen education of the students, bringing evidence of contextualized learning.
