Concepções alternativas de pessoas com deficiência visual sobre óptica : uma análise fenomenológica

Abstract

This research sought to investigate the ideas and conceptions that students with visual impairments have when encouraged to answer questions on concepts and knowledge related to physical optics. For the research, three students with visual impairments at different levels of education were interviewed, participating later in an activity based on the use of tactile models. To identify the conceptions of these students, we seek the phenomenological method, proposed by Edmund Husserl, understanding the phenomena about the students were asked and abetted to submit explanations. The results derived from phenomenological analysis of the speeches of the three students, indicate the existence of some conceptions that resemble the common sense conceptions, like light propagates as waves, the perception of the occurrence of the vision process resembles the model known as "light bath", the interpretation of sunlight and artificial light as having different natures and the notion that are lenses that correct vision defects.
