Proposal of a tactile model for teaching Organic Chemistry for visually impaired people

Abstract

This proposal aims to discuss the development of a didactic model that facilitates the teaching of organic chemistry for visually impaired students, and that can be applied to other chemical structures. The teaching of chemistry is often difficult to understand, because it works with abstract contents, which causes many learning difficulties for students of basic and higher education, in addition to generating mistaken views about this science. In this way, we highlight the importance of using tactile didactic models that allow the perception of molecular structures in the macroscopic dimension, whether for visually impaired or visually impaired students, in the area of organic chemistry. We begin with a review of the literature in the field to highlight the importance of inclusive education and the challenges of understanding chemistry teaching, particularly due to the complexity and constant use of theoretical models presented only orally by teachers. The proposed tactile didactic model points out a path that contributes to the teaching of organic chemistry, specifically the content of hydrocarbons and with the list of researches that are dedicated to a more inclusive teaching of chemistry and production of didactic materials.
