The Improving Accessibility of E-Learning Systems for Visually Impaired Students in Sri Lanka: An Evaluation Based on Wcag Principles

Sažetak

Purpose: This study aims to investigate the means to improve the accessibility of e-learning systems for visually impaired students in Sri Lanka. It focuses on addressing the challenges these students face, particularly during the shift to online learning brought about by the pandemic.

Design: The study builds on the Web Content Accessibility Guidelines (WCAG), utilizing the POUR principles—Perceivable, Operable, Understandable, and Robust—as the conceptual framework.
Methodology: A quantitative design was employed to examine the impact of these principles on learner satisfaction.
Approach: The sample consisted of 150 visually impaired students from the Ceylon Deaf and Blind School, selected through purposive sampling.

Findings: The analysis revealed that both the Perceivable and Understandable factors had a positive and significant impact on learner satisfaction. However, the Operable and Robust factors did not show a significant impact, indicating areas that require enhancement.

Originality/Value: This research contributes to the field by providing empirical insights into the accessibility challenges faced by visually impaired students in Sri Lanka. It underscores the need for improvements in e-learning system design, particularly in operability and robustness, to ensure equitable access.
