Avaliação de acessibilidade na web aplicada ao ensino de língua estrangeira: um estudo de caso

Abstract

This paper presents a technical accessibility assessment of an introductory exercise on the Duolingo platform, a widely used tool for foreign language learning. The objective was to verify the content's degree of compliance with the Web Content Accessibility Guidelines (WCAG) using the WAVE automated tool. The analysis identified barriers primarily related to the lack of alternative text for visual elements and inadequate contrast on interactive components, aspects that can compromise the experience for users with visual impairments or color blindness. The results highlight that, although the platform adopts modern responsive design practices, there are still significant gaps in meeting the principles of perceivability and robustness as defined by the WCAG.
