Sanchez-Gordon, Sandra; Luján-Mora, Sergio. Adaptive Content Presentation Extension for Open edX – Enhancing MOOCs Accessibility for Users with Disabilities, Eighth International Conference on Advances in Computer-Human Interactions  (ACHI  2015), pp.181-183, Lisbon (Portugal), February 22-27, 2015.  ISSN: 2308-4138.

Abstract

In this paper, we propose a three-layer architecture to extend the Massive Open Online Courses (MOOCs) platform Open edX to enhance course content accessibility for users with disabilities. Because of their open nature and global scope, MOOCs are a great opportunity for people with disabilities that might not be able to engage in learning otherwise. The goal of the proposed extension is to enhance MOOCs’ accessibility by adapting course content to student needs, preferences, skills and situations. In this approach, the user does not need to know what adaptations should be applied to the MOOC to make it more accessible for them. The user only needs to keep updated their accessibility preferences in their user profile. The extension automatically applies all the necessary adaptations as commanded by the adaptive engine and provides the presentation layer with the content best suited for the user.
