Polarizador de luz: um estudo sobre a construção e a aplicação de um dispositivo didático

Abstract

Educational institutions face numerous challenges in teaching Physics, a subject that often takes an abstract approach. The complexity of physical concepts arises from their nature, which is often not directly observable, making comprehension difficult for students. In response to the challenges teachers encounter when addressing the topic of Optics, particularly in relation to light polarization, the initiative to create an alternative polarizer was developed. This study was conducted with a 3rd -year high school class at a state school, aiming to assess the effectiveness of this pedagogical tool. To collect data, two questionnaires were administered, one at the beginning and one at the end of the study, to evaluate the students' progress. The results indicated that the proposed educational product achieved the established objectives. Although initial gaps in understanding the concepts of light polarization were identified, the application of the alternative polarizer significantly contributed to improving thestudents'
