Atividades Experimentais para o Estudo da Refração da Luz no Ensino Médio, uma Proposta de UEPS

Abstract

In this work we present a proposal for a Potentially Meaningful Teaching Unit (UEPS) on the theme of refraction of light in transparent media, in the context of geometric optics, based on the principles of the Theory of Meaningful Learning (TAS) by David Ausubel. The UEPS was applied and analyzed in a third-grade high school class, in a school in the Metropolitan Region of Curitiba - PR, based on the assumption that the experimental activities developed, applied and evaluated in the light of the TAS principles, could contribute to alleviate some of the learning problems encountered by the teacher in the teaching of physics regarding the content of light refraction. To investigate the results and search for evidence of learning, conceptual maps were used, indicated as important methodological tools in the process of differentiated and progressive assessment. In the different moments of the UEPS, there was a great involvement of students in the process, individually and in groups, and an increase in the complexity of their mental and conceptual maps, factors that can be read as indications that the experimental activities contributed as facilitators of teaching, motivating and mobilizing the students and showing themselves as instruments to support the teacher in his search for differentiated and attractive classes.
