Tecnologias digitais no ensino de alunos surdos: uma análise do uso dos aplicativos Hand Talk e LibrasLab em Caxias - MA

Abstract

The inclusion of deaf students in mainstream classrooms still faces challenges—such as a lack of teacher training in LIBRAS (Brazilian Sign Language), a scarcity of accessible materials, and limited institutional support—which compromise the quality of education. In this context, assistive technology emerges as a promising resource to make the learning process more visual, interactive, and inclusive. The research is guided by the question: How can the Hand Talk and LIBRASLab applications contribute to improving the teaching and learning process for deaf students in mainstream classrooms in the municipality of Caxias, Maranhão? The general objective is to analyze the contributions of these applications to the teaching and learning process of deaf students. Specific objectives include: describing the use of technologies and educational apps; presenting the functionalities of Hand Talk and LIBRASLab while highlighting their pedagogical potential; implementing the apps in selected school settings and observing their interaction with deaf students; analyzing the effects of using the apps on the teaching and learning process based on pedagogical records and observations; and developing a guidance e-book—based on research with participants—that addresses the use of Hand Talk and LIBRASLab. The study was conducted with teachers of the final years of elementary education and deaf students within the municipal school system of Caxias, Maranhão, using interviews, questionnaires, and classroom observations, alongside a mixed-methods analysis with a qualitative focus. Results indicate that the use of bilingual applications fosters student engagement—particularly in visual and interactive activities—promoting autonomy, curiosity, and motivation, although limitations regarding internet access and a lack of electronic devices persist. The study concludes that it is necessary to invest in teacher training regarding digital technologies and inclusive methodologies, as well as in public policies that ensure adequate infrastructure and universal access to devices and high-quality internet.
