Atividades experimentais no ensino de óptica com materiais de baixo custo aplicados no segundo ano do ensino médio

Abstract

What measures should take the professor of Physics problem by surrounding the high school, with students who are unmotivated and lack of conditions for work of practical lessons? To investigate the performance of experimental Physics classes in high school, especially those involving low-cost material in the teaching of optics in the second year, is the purpose of this study. It is shown in the context of science teaching the emergence of practical classes, as well as the circumstantial difficulties due to lack of materials in laboratories, based on the study of articles that discuss and evaluate the practice applied with students of 2nd year high school, a private school in the city of Aracati-Ce. To reach the conclusion of data analysis, a study was done about the pedagogical theories related to the experimental practice, which purpose to observe the behavior of students due to stimulus and positive reinforcement. In observational studies, there are completions of practical activities with experimentation, post-assembly test run by the students themselves, in which instead of using equipment ready themselves build, thus arousing their creativity and reasoning in search of a meaningful learning.
