Teaching Chemistry for Visually Impaired Students by a Periodic Table Adaptation

Abstract

This paper aims to present the development of a periodic table adaptation for students with visual impairment. In the first stage of the research, a systematic literature review was conducted, in which articles related to the production of adapted periodic tables for these students were sought in ENPEC and ENEQ events records, finding a total of nine articles. The limitations and potential of these materials were analyzed, so that the adapted material described in the article could be manufactured, following the specifications of NBR 9050. First, an acrylic table was made with laser marking and writing in Braille in the format of the periodic table, keeping the smallest possible size to overcome one of the founded limitations. As an auxiliary material, Braille cards were created for each chemical element that complements the information omitted due to the reduction in the size of the table produced. It is expected to contribute to the analysis of adapted materials characteristics and that the didactic resource presented here can overcome the limitations found so that it complements the study of the periodic classification of elements and, in a greater scope, contributes to the inclusion of visually impaired students in Chemistry teaching.
