Abstract
The Open Educational Resources (OER) initiative is being promoted by governments and organizations related to education around the world in order to improve and equalize access to quality educational content to all people. OER are digital contents for teaching-learning purpose available through websites, released under an open intellectual property license to allow their free use for self-learners and educators. The OER-based learning is involved in formal and non-formal education and can be included in different educational environments, including Elearning. However, despite the growing availability of OER, most of these resources are not accessible to people with disabilities. Hence, the accessibility issues need to be addressed in order to include this vulnerable group of population in OER-based learning opportunities. An accessible environment should be twofold: accessibility of resources and accessibility of OER website that offers the resources. In this paper, we propose a process to guide the creation and release of accessible educational resources and their application to a case study. This case refers the creation of an educational resource accessible for people with severe visual impairments and its release through important OER websites. This accessible resource is a full online course that includes downloadable PDF documents. Moreover, OER websites, where this resource is released, are accessible for people with disabilities. Furthermore, this paper highlights the specific considerations for visual impairments in the design of this resource, and accessibility validation tests conducted with automated tools, simulation software, and user testing. The results of this experience allow recognizing certain problems in the creation of accessible resources as well as the limitations of OER websites to serve people with disabilities. In addition, this work contributes to the awareness about the inclusive vision of OER-based learning.

User Experience for Disabled Users in Open Educational Resources Websites
User Experience for Disabled Users in Open Educational Resources Websites
Rosa Navarrete, Sergio Luján-Mora
Latin American Journal of Computing, 2(3), p. 21-32. ISSN: 1390-9134.
Abstract
Open Educational Resources (OER) are digital materials for teaching-learning purpose released under an open license that are available through websites. In the last decade, some governments have encouraged the development and using of OER in order to contribute to the achievement of the right to education for everyone. Besides, inclusion of people with disabilities is a global concern that need to be addressed in all living aspects including education as one of the fundamental right for human development. In this research we address the user experience in OER websites —considering the perspective of users with disabilities— in order to recognize possible barriers in web design. The conformance criteria considered for this reviewing are mandatory aspects of user experience in relation to Web accessibility and Web usability.

Use of Linked Data to Enhance Open Educational Resources
Use of Linked Data to Enhance Open Educational Resources
Rosa Navarrete, Sergio Luján-Mora
14th International Conference on Information Technology Based Higher Education and Training (ITHET 2015), p. 1-6, Caparica (Portugal), June 11-13 2015. ISBN: 978-1-4799-1756-3.
Abstract
Open Educational Resources (OER) are freely accessible, openly licensed documents and media that are useful for teaching, learning, research, and assessing. OER are usually conceptualized as Learning Objects (LO). While there is a big abundance of OER available today, finding, querying, and integrating/interlinking these resources, to say the least, is difficult. On the other hand, Linked Data is a mechanism to tackle the issues related to publishing and to exploring data on the Internet. Linked Data allows a person or machine to explore the Web of Data. In the last years, many efforts have been carried out using Linked Data in different domains. However, Linked Data has not been used extensively to publish and explore OER. In this paper, we review the current status of use of Linked Data to manage OER and we propose the use of Linked Data to enhance the use of OER. Linked Data offers a mechanism where OER can be most easily found to use, reuse, sharing and remix.

Evaluating findability of open educational resources from the perspective of users with disabilities: a preliminary approach
Evaluating findability of open educational resources from the perspective of users with disabilities: a preliminary approach

Abstract
e-Education is an umbrella term that refers to educational collaborative environments supported by technology that related not only formal academic institutions programs but also self-learners and teachers around the world. This educational paradigm is of paramount importance for society nowadays, because expands access opportunities to education at all levels. These learning environments can take advantage of Open Educational Resources. Using OER is a growing trend and it is turning into a recommendation by some governments and international education forums. Nevertheless, in spite of the availability of OER websites, quite a few of them do not consider accessibility design principles, therefore these websites present access barriers for users with disabilities. Besides, only a reduce number of these websites offer accessible resources, i.e. digital contents suitable for users with disabilities. On the other hand, in web environment, findability is a design consideration that improves the user's searchable experience by simplifying the location and acquisition of elements in websites. In this restricted scenario, findability of educational resources is a key issue for users with disabilities. In this research, we address the issue of findability of Open Educational Resources (OER), from the perspective of inclusive participation of users with disabilities, by considering three aspects: web accessibility, some usability best practices oriented to users with disabilities and Information Architecture. The evaluation is performed in some important and well known OER websites.

Evaluating accessibility of Open Educational Resources websites with a heuristic method
Evaluating accessibility of Open Educational Resources websites with a heuristic method
Rosa Navarrete, Sergio Luján-Mora
Proceedings of the 9th International Technology, Education and Development Conference (INTED 2015), p. 6402-6412, Madrid (Spain), March 2-4 2015. ISBN: 978-84-606-5763-7.
Abstract
Open Educational Resources (OER) are digital contents with educational purpose available through websites that can be freely reused by educators and self-learners. There is a growing trend in using OER to improve quality in teaching and learning processes, and the importance of OER is recognized in government initiatives and international instances such as UNESCO in the 2012 World Open Educational Resource Congress. However, people with disabilities usually face access barriers when using these resources. The causes of access barriers are two-fold: OER can be no accessible or websites can have accessibility issues in their design. In previous works, we conducted accessibility evaluation in OER websites through automated tools as a preliminary and quick way of evaluation, but with some drawbacks related to the reliability of results. The aim of this research is to complement the evaluation of web accessibility in OER websites, using a heuristic method based on “Barrier Walkthrough”, proposed by Giorgio Brajnik, a web accessibility researcher. This method considers the context of use of the website for persons with specific disabilities, and tests the potential barriers for achieving goals. The results presented in this paper contribute to validate the method and offer another perspective of web accessibility evaluation of OER websites based on specific disabilities. Additionally, this work is part of a method for evaluating the quality of OER and the websites where these are published.
