Can user recommendations be useful for improving MOOCs accessibility? A project for inclusive design and profitable feedback
At present there are no applications which include accessibility revisions for Massive Open Online Courses (MOOCs), neither in the context of MOOCs provider institutions nor from the point of view of any Open Educational Resource (OER) initiative. In this paper an approximation to this problem is presented, in the form of a specific web portal which will offer the possibility for any user to freely judge the accessibility of a certain course and advice about the missing means of meeting user needs or required adaptations. This kind of user feedback can be of great value for the future development of MOOC platforms, courses and the educational resources. The development of this web tool will gather valuable information directly from the users themselves to improve the educational quality and accessibility of these learning environments
Investigating the appropriateness and relevance of mobile web accessibility guidelines
The Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C) develop and maintain guidelines for making the web more accessible to people with disabilities. WCAG 2.0 and the MWBP 1.0 are internationally regarded as the industry standard guidelines for web accessibility. Mobile testing sessions conducted by AbilityNet document issues raised by users in a report format, relating issues to guidelines wherever possible. This paper presents the results of a preliminary investigation that examines how effectively and easily these issues can be related by experts to the guidelines provided by WCAG 2.0 and MWBP 1.0.

An investigation into the perspectives of providers and learners on MOOC accessibility
An effective open eLearning environment should consider the target learner’s abilities, learning goals, where learning takes place, and which specific device(s) the learner uses. MOOC platforms struggle to take these factors into account and typically are not accessible, inhibiting access to environments that are intended to be open to all. A series of research initiatives are described that are intended to benefit MOOC providers in achieving greater accessibility and disabled learners to improve their lifelong learning and re-skilling. In this paper, we first outline the rationale, the research questions, and the methodology. The research approach includes interviews, online surveys and a MOOC accessibility audit; we also include factors such the risk management of the research programme and ethical considerations when conducting research with vulnerable learners. Preliminary results are presented from interviews with providers and experts and from analysis of surveys of learners. Finally, we outline the future research opportunities. This paper is framed within the context of the Doctoral Consortium organised at the TEEM'17 conference
Measuring and comparing the reliability of the structured walkthrough evaluation method with novices and experts
Effective evaluation of websites for accessibility remains problematic. Automated evaluation tools still require a significant manual element. There is also a significant expertise and evaluator effect. The Structured Walkthrough method is the translation of a manual, expert accessibility evaluation process adapted for use by novices. The method is embedded in the Accessibility Evaluation Assistant (AEA), a web accessibility knowledge management tool. Previous trials examined the pedagogical potential of the tool when incorporated into an undergraduate computing curriculum. The results of the evaluations carried out by novices yielded promising, consistent levels of validity and reliability. This paper presents the results of an empirical study that compares the reliability of accessibility evaluations produced by two groups (novices and experts). The main results of this study indicate that overall reliability of expert evaluations was 76% compared to 65% for evaluations produced by novices. The potential of the Structured Walkthrough method as a useful and viable tool for expert evaluators is also examined. Copyright 2014 ACM

Accessibility Variability Model: The UTPL MOOC Case Study
Several approaches to define Variability Models (VM) of non-functional
requirements or quality attributes have been proposed. However,
these approaches have focused on specific quality attributes rather
than more general non-functional aspects established by standards
such as ISO/IEC 25010 for software evaluation and quality. Thus,
developing specific software products by selecting features and
at the same time measuring the level of compliance with a standard/
guideline is a challenge. In this work, we present the definition
of an accessibility VM based on the web content accessibility guides
(WCAG) 2.1 W3C recommendation, to obtain a quantitative measure
to improve or construct specific SPL products that require to be
accessibility-aware. This paper is specially focused on illustrating
the experience of measuring the accessibility in a software product
line (SPL) in order to check if it is viable measuring products and
recommending improvements in terms of features before addressing
the construction of accessibility-aware products. The adoption
of the VM accessibility has been putted into practice through a pilot
case study, the MOOC (Massive Open Online Course) initiative of
the Universidad Técnica Particular de Loja. The conduction of this
pilot case study has allowed us to illustrate how it is possible to
model and measure the accessibility in SPL using accessibility VM,
as well as to recommend accessibility configuration improvements
for the construction of new or updated MOOC platforms.Ministerio de Economía, Industria y Competitividad TIN2016- 79726-C2-1-RMinisterio de Ciencia, Innovación y Universidades RTI2018-101204-B-C22Agencia Estatal de Investigación TIN2017-90644-RED
Exploring WHO communication during the COVID 19 pandemic through the WHO website based on W3C guidelines: accessible for all?
Health crisis situations generate greater attention and dependence on reliable and truthful information from citizens, especially from those organisations that represent authority on the subject, such as the World Health Organization (WHO). In times of global pandemics such as COVID-19, the WHO message “health for all” takes on great communicative importance, especially from the point of view of the prevention of the disease and recommendations for action. Therefore, any communication must be understandable and accessible by all types of people, regardless of their technology, language, culture or disability (physical or mental), according to the World Wide Web Consortium (W3C), taking on special relevance for public health content. This study analysed whether the WHO is accessible in its digital version for all groups of citizens according to the widely accepted standards in the field of the Internet. The conclusion reached was that not all the information is accessible in accordance with the Web Content Accessibility Guidelines 2.1, which implies that there are groups that are, to some extent, left out, especially affecting the elderly. This study can contribute to the development of proposals and suggest ways in which to improve the accessibility of health content to groups especially vulnerable in this pandemic.This research has received funds from a Plan Propio of University of Malaga and UMA18-FEDERJA-148
How accessibility guidelines are used in Spanish World Heritage Websites: an exploratory study
This paper presents an exploratory study on the accessibility of Spanish World Heritage website homepages in the Spanish language.
The study sample comprised 78 homepages from the institutional websites of the 47 cultural, natural and mixed assets considered as World Cultural Heritage by The United Nations Educational, Scientific and Cultural Organization (Unesco). These homepages have been analysed using online accessibility validator tools, following the Web Content Accessibility Guidelines (WCAG) 2.0 recommendation for the different levels of priority. The compiled data were employed in a quantitative study on adherence to WCAG guidelines. Furthermore, the types of errors made using the perspective of accessibility and usability were identified, and the application rate was calculated for these accessibility guidelines according to the type of entity managed by the websites and pages.
The results show that more than 25% of the cases analysed had 10 accessibility errors or fewer. Moreover, it was only necessary to correct one or two types of errors in close to 40% of them. The paper draws the conclusion that, despite technological and legislative advances that make public entity websites accessible, there is still much to do before complete web accessibility and usability at AA and AAA level can be achieved.
Identifying accessibility problems on institutional websites constitutes the first step towards creating web content that is easy to access and manage for users with disabilities. In this regard, this study contributes to improving web content according to objective guidelines such as those encouraged by the WCAG 2.0.
This article provides information on how accessibility and usability guidelines are implemented by institutional websites for Cultural Heritage deemed especially important. This is an issue with significant implications for users and for which, however, there is a lack of prior studies. As a result, the value and originality of this paper can be considered evident
