Ilusões de ótica e sistema nervoso: relato de uma intervenção investigativa no ensino médio

Abstract

This final course paper presents the report and reflections of an investigative pedagogical intervention about the nervous system, focusing on sensory perception and brain interpretation processes, carried out with students from the second year of evening high school in Hortolândia, São Paulo, Brazil. The methodology, of a qualitative and interventionist nature, was structured in six classes, ranging from the survey of students’ prior knowledge through explanatory diagrams to experimentation in investigative stations, including the Cornsweet illusion, the Stroop Effect and topdown processing. The results, obtained through the Socrative platform and classroom observations, indicate that the students moved beyond simple observation toward the formulation of more complex hypotheses and experimental planning. It can be concluded that, by challenging students’ confidence in their own sensory perceptions, the intervention promoted expressive student participation, in which perceptual error played a central role as a driving element for the construction of scientific knowledge, contributing to the understanding of Biology as a tool for critical interpretation of reality.
