Accessibility for educational resources

This data aims to raise awareness of any professional who develops educational applications, that apply accessibility standards to generate inclusive and accessible applications. For within the group of possible users there may be participants with some type of visual disability, such as users with low vision and elderly people. On the other hand, we must emphasize that developing an accessible application does not have to go against an attractive graphical interface, that is, an accessible application does not necessarily have to be “unsightly.”
It is convenient to remember that not all visual disabilities are the same, and computer management skills also depend on the age of the user, so in the article, these two variables will always be considered. Nowadays, it is necessary to consider the different levels of education, especially for elderly patients and those with disabilities. Therefore, the educational resources of the Tele-habilitation platform must provide instantaneous and ubiquitous access to all types of services and content, including documents and digital resources.
The digital educational resources have become a valuable alternative to support the teaching and learning processes, taking advantage of the possibility of presenting the contents through different multimedia formats. Therefore, it is necessary that educational resources for learning apply accessibility features that allow the interaction of users regardless of their conditions and preferences. This document presents a proposal for the evaluation of the accessibility of multimedia educational resources, where it is suggested to apply the WCAG 2.1 in addition to a series of phases to automatically and manually assess the level of accessibility of the educational resources used in the platform of telerehabilitation.

本数据集旨在提升所有开发教育应用程序的专业人士的认知，使其了解需遵循无障碍标准以打造兼具包容性与可访问性的教育应用程序。这是因为在目标用户群体中，可能存在各类视觉障碍人士——比如低视力用户与老年群体。另一方面，需明确：开发无障碍应用程序不必以牺牲美观的图形界面为代价，换言之，无障碍应用程序绝非必然“不美观”。
需牢记：并非所有视觉障碍都完全一致，且用户的计算机操作能力也与其年龄相关，因此本文将始终兼顾这两项变量。当下，需充分考量不同的受教育水平，尤其针对老年患者与残障群体。因此，远程康复（Tele-habilitation）平台的教育资源需实现全类型服务与内容（含文档与数字资源）的即时、普适性访问。
数字教育资源现已成为支撑教学与学习过程的重要替代方案，可依托多模态格式呈现教学内容。因此，学习类教育资源需具备无障碍功能，确保无论用户的身体状况与使用偏好如何，均可正常交互。本文件提出了一项多媒体教育资源可访问性评估方案，建议采用网页内容无障碍指南2.1（WCAG 2.1），并结合一系列自动化与人工评估步骤，对该远程康复平台所用教育资源的可访问性等级进行评测。
