Atividades experimentais no ensino de óptica

Abstract

Among the many difficulties in teaching physics, the lack of laboratory structure in schools and the mechanism of teaching are two major factors. This study aimed to develop a didactic sequence that helps physics teachers to implement, at low cost, an experimental teaching in high schools. For this purpose, it was used the Meaningful Learning of David P. Ausubel through the UEPS - Potentially Significant Teaching Units, proposed by Marco Antônio Moreira. The educational product presented here was designed to favor a differentiated assessment of teaching and learning and participation in activities that encourage students to develop the pleasure of learning. Thus, acting in two central problems of the Brazilian education: the lack of physical structure of the schools and the lack of interest of the students for the learning in the area of sciences. In most cases, physics teaching is mechanically handled by teachers which leads students to perceive this subject as an abstract set of unintelligible formulas and numbers. The manual produced here deals with the scattering of white light through a DVD, the production and use of a Newton disc, the use of monochrome lamps to demonstrate their effect when applied to colored objects and the properties of flat and spherical mirrors. The application of this manual yielded satisfactory results and profoundly stimulated student participation.
