TECHNICAL AND PEDAGOGICAL USABILITY AND DIGITAL ACCESSIBILITY IN EDUCATIONAL TECHNOLOGIES FOR CHILDREN WITH DYSLEXIA: A MULTIDIMENSIONAL HEURISTIC EVALUATION OF THE EDUEDU INTERFACE
Usability; Digital Accessibility; Heuristic Evaluation; Dyslexia.
The literacy acquisition process is a complex and multifactorial phenomenon, involving cognitive, linguistic, sensory, emotional, and sociocultural aspects. For children with dyslexia, this journey presents significant barriers, especially in the development of reading and writing. In this context, digital educational technologies that incorporate usability and accessibility guidelines can play a fundamental role in supporting learning and strengthening the autonomy of these students. This research proposes a multidimensional heuristic evaluation of the interface of the EduEdu application, developed by the ABCD Institute, aimed at teaching literacy to children with dyslexia. The investigation is based on observation, identified through systematic literature mapping, of gaps in studies that integrate technical, pedagogical, and inclusive dimensions in the evaluation of digital educational interfaces. The methodology will be based on Munari's Project Methodology (2015), utilizing the inspection method and the heuristic evaluation technique (Nielsen, 1994; Santa Rosa and Santa Rosa, 2020), with the participation of multidisciplinary experts. The analysis protocol articulates Nielsen's principles (1994), Nokelainen's pedagogical criteria (2006), WCAG 2.2 guidelines (W3C, 2024), and the recommendations of the British Dyslexia Association (2023). The overall objective is to evaluate the technical and pedagogical usability and digital accessibility of EduEdu, identifying strengths and inconsistencies that impact the learning experience of children with dyslexia. As a result, the aim is to develop a digital multidimensional heuristic evaluation guide, to be made available on the Pluni platform, contributing to future evaluations and the improvement of more inclusive and pedagogically appropriate educational technologies.
