A utilização da experimentação com lasers e materiais de baixo custo no ensino de óptica

Abstract

The following paper discusses the use of laser experimentation as an important didactic tool in teaching optics for meaningful learning. The main objective of this study is to investigate whether the use of low-cost lasers and materials as a didactic tool will provide significant learning in the optics teaching of high school students. Regarding Didactic Resources and Significant Learning the main authors used as theoretical references were: Silva, Soares, Alves and Santos (2012), Ausubel (1980), Moreira (2000) and others. And related to the optics, the theorists approached were Martins and Silva (2013), Hewit (2002) and Paiva (2014). The research is a qualitative and exploratory approach in which the subjects selected for this research comprise a population of 120 students regularly enrolled in the 2nd year of the Benjamin Baptista School Unit, where the technique used to analyze the data was content analysis, Since they were divided into three thematic categories (Prior Knowledge, Didactic Resource and Construction of Concepts and Acquired Knowledge) always analyzing and relating them to the theoretical framework studied. However, experimentation brings physical concepts closer to the student's reality, that is, through this tool it is possible to transform the phenomena and the abstract concepts that involve optics in concrete, where each one formulates his hypotheses and draws his own conclusions.
