Concepções dos alunos da Unidade Escolar Demerval Lobão sobre a natureza da luz e suas tecnologias

Abstract

This article analyzed the perception of the students from Demerval Lobão School on the nature of light and its technologies, in view of the importance of such understanding for humanity. In 2015, the UN together with UNESCO celebrated light and its properties. Important events were celebrated, such as the 150th anniversary of Maxwell's proposal, which proposes that light is an electromagnetic phenomenon. They also celebrated the 100th anniversary of Einstein’s General Theory of Relativity, which brought many contributions for science. This study, in relation to its objective, is characterized as a descriptive approach qualitative. The study was conducted in the town Angical do Piaui - PI. The data were collected through closed questionnaires and then represented in vertical columns, presented in graphs, for analysis. From an analytical reading of the graphs, it was noticed that students have misconceptions about the nature of light, but understand that light is essential for the existence of any living being and the mechanical establishment of the Universe. Except for Albert Einstein, students are unaware about scientists as Maxwell and Fresnel, who contributed to the evolution of current scientific concept of the nature of light. It was also noticed that most of the interviewed students believed to be in a static universe. Like this, they are still stuck in an already exceeded view of Universe model
