Eficiência energética de lâmpadas: construção e aplicação de luxímetro didático comparativo

Abstract

This study presents the scope of learning physical concepts related to the experimental educational product LuDiCo (acronym for comparative didactic luximeter). This device is used to compare measurements made in three different lamps. It thus enables one to decide which of them is the most energy efficient. The LuDiCo also enables the study of frequency and energy through the luminous intensity of the dimmerized incandescent lamp connected to the photo sensor and the number of LEDs with different colors activated forming a scale. This research presents at its base the methodological pluralism that favors the structuring of a didactic sequence adaptable to the needs of the students. Emphasis is placed on the use of methods: meaningful learning and research teaching. The didactic sequence was applied in regular high school classes of a state school in the western region of the municipality of Juiz de Fora. This dissertation highlights that the combination of technologies present in everyday life or of scientific use, associated with investigative pedagogical methods in which students construct their knowledge in a more autonomous way, allows efficient learning through motivation and active learning. It is important to emphasize the importance of relating the knowledge provided by the school environment to first-hand experiences, as it makes clear the importance of science teaching, especially Physics Teaching.
