Cartilha digital interativa de Química: sinalização de materiais de laboratório

Abstract

Teaching Chemistry presents significant challenges for deaf students, particularly due to the scarcity of accessible didactic materials that support the understanding of instruments used in laboratory practices. In this context, this study aimed to develop a bilingual interactive digital booklet (Brazilian Sign Language – Libras/Portuguese) aimed at presenting signs for laboratory materials. This qualitative, exploratory, and documentary research involved identifying the main instruments used in practical classes, researching and cataloging their respective signs from different visual and digital sources, and organizing the instructional content. The final product brings together illustrations, sign-language videos, links, quick response codes (QR Codes), and a questionnaire focused on visual learning. The analysis indicated that existing materials display gaps and variations in signs, reinforcing the relevance of the guide developed. It was also observed that the material produced contributes to the recognition of laboratory instruments and supports students, teachers, and interpreters by expanding technical vocabulary and enhancing content comprehension. As a limitation, it is important to highlight the impossibility of applying the guide directly with the target audience, which points to the need for future studies to evaluate its effectiveness in school contexts. It is concluded that the guide contributes to the promotion of communicational accessibility in Chemistry education.
