Automation of the generation of accessible digital educational material for students with visual disabilities
(Springer, 2020) Cabrera Medina, Boris Fabricio; Zúñiga Prieto, Miguel Ángel
Online learning has grown in the last years, where educational institutions are offering courses or study programs in different knowledge areas. Online learning allows students to participate actively in cooperative learning activities, interacting without the preconceived notions of disability that other participants could have, which affects the relationship. However, these advantages have often not become a reality for most people with disabilities, especially in the educational context. For instance, courses’ web pages are not accessible for people with visual disabilities, which makes the experience of taking a course frustrating and tedious. This article proposes a Model-Driven Development approach for supporting the design and generation of accessible educational material, for example, accessible Learning Objects (LO). This approach provides a software infrastructure that includes: (i) A Domain-Specific Language and its corresponding graphic editor that supports accessible LO’s design. Helping teachers during the instructional design and allowing them to describe accessibility requirements for students with visual disabilities. (ii) A LO’s generation engine that takes as input design artifacts and generates the source code that implements accessible LO. Abstracting teachers from technological aspects (e.g., programming language instructions) necessary to construct LO with accessibility features. The applicability of this approach is illustrated by using the DSL and the generation engine to design and automatically implement an accessible LO according to the accessibility profile specified during design. Finally, the generated LO was published in the Learning Management System Moodle. © 2020, Springer Nature Switzerland AG.
Automatización de la generación de material educativo digital como soporte a los procesos de enseñanza -aprendizaje considerando aspectos de accesibilidad

The Learning Objects are a collection of multi-media content such as: images, videos, text, etc., that helps the teacher to present their educational material in a unique way for their students, making learning a more didactic process, since it allows the teacher create different activities where students will have a greater participation, making this an advantage of the Learning Objects in addition the student will always have the content available fromany place where they have an internet connection, that is why this thesis purpose is to include people with disabilities so they can take advantage of online learning, normally a teacher generates the educational material without considering the special needs of students with some type of disability, making learning Complicated for these students, either by very light colors, texts very small, videos without subtitles, etc. Nowadays with the advantages that the web offers us,we could realice that there is no inclusion for people with disabilities (visual, auditory, cognitive, etc.), these people have difficulties to surf the web, since the available web pages they do not count or were not designed so that people with disabilities can use them and take advantage of them in an optimal way, which makes the experience of using the web frustrating and tedious. This document proposes a technologicalsolution (hereinafter a solution) to support teachers during the construction of accessible LO for students with disabilities. This proposal is based on a Model-Driven Development (MDD) approach to overcome heterogeneity in the technological toolsthat teachers require to build accessible LO. Allowing teachersto rely on different activities ofthe LO construction process, taking into account aspects of accessibility through i) A domain-specific language (DSL) and its corresponding graphic editor that supports the design of LO; facilitating not only the instructional design of the courses but also the specification of the accessibility requirements of students with disabilities. ii) An LO generation engine that takes as input the information described during the design and automatically creates the accessible LO web pages; As a final result, the accessible LO packaged in SCORM format will be obtained, and then deployed in the different virtual learning platforms (Learning Management System - LMS)
