Sampson CAVA 2011, Bogota, Colombia, November 2011 Research Unit on Advanced Digital Systems and Services for Education and Learning (ASK) • Historically, the issue of accessibility in Web-based Education has been treated in two main directions: – Provide with Accessible Learning Materials (De Marsico etal, 2006; Di Iorio, 2006) – Provide with Accessible Course Management Systems (Desire2Learn, 2008) • Is this enough for today’s educational expections? Earl, S., Felix, M., Gilson, C. and Petri, K. (2008).

  • 8. University of Piraeus Department of Digital Systems Centre for Research and Technology – Hellas (CE.R.T.H.) Informatics and Telematics Institute (I.T.I.) D. G. Sampson CAVA 2011, Bogota, Colombia, November 2011 Research Unit on Advanced Digital Systems and Services for Education and Learning (ASK) • In practice, there are three main approaches for enhancing accessibility in technology-enhanced learning (Nevile et al, 2005): – To create Universally Accessible Resources (Web-based content and/or applications) that meet all the accessibility requirements. The main drawback with this approach is that, typically, Resources are Accessible-by-Everyone, but Optimal-for-None (“one-size does not fit all” personalisation rule). – To create multiple versions of the Resources, customised based on the different needs and expectations of the anticipated individual user. This is a rather unrealistic anticipation in practical terms. Typically, only the main version is updated and maintained to a high quality level over time. – To built Universally Accessible Resource Systems, that is, systems that can handle user-centered configurations of resources, tools, applications. This Access4All Approach requires accurate descriptions of • Learners’ Preferences and Needs • Resources (Content and/or Tools/Applications) and Services Characteristics Nevile, L., Cooper, M., Heath, A., Rothberg, M. and Treviranus, J. (2005). Learner-Centered Accessibility for Interoperable Web-based Educational Systems, In: International World Wide Web Conference (WWW2005), 10-14 May 2005, Chiba, Japan.

Sampson CAVA 2011, Bogota, Colombia, November 2011 Research Unit on Advanced Digital Systems and Services for Education and Learning (ASK) • Early systems implementation suffered by the lack of interoperability at various levels: content, interactions (learners-tutors, learners-learners, learners-tools), tools and applications, adding extra barriers to access4all. • The emerge of – Learning Technology International Specifications (IEEE Learning Object Metadata, SCORM, IMS Learning Design, IMS Questions and Test Interoperability, IEEE Reusable Competency Definitions, …) – Web Accessibility Standards (Web Content Accessibility Guidelines [WCAG], Evaluation and Report Language [EARL], User Agent Accessibility Guidelines [UAAG], Authoring Tool Accessibility Guidelines [ATAG], Accessible Rich Internet Applications [WAI-ARIA]) is now improving this situation, although still global adoption is at early stages and extra effort is needed to ensure synchronisation and orchestration of these specifications.

  • 10. University of Piraeus Department of Digital Systems Centre for Research and Technology – Hellas (CE.R.T.H.) Informatics and Telematics Institute (I.T.I.) D. G. Sampson CAVA 2011, Bogota, Colombia, November 2011 Research Unit on Advanced Digital Systems and Services for Education and Learning (ASK) • IMS Global Learning Consortium (a global consortium of organizations working together to develop specifications for learning technology) has produced: – The IMS Accessibility for Learner Information Package (IMS AccLIP) Information Model: it adds a new element on IMS LIP to allow learner <accessibility> preferences to be defined. Rather than targeting at the description of the learner's disabilities, it allows users to explain how they interface and use a computer-mediated learning system, with their preferences being grouped into <display>, <control>, and <content> elements. – The IMS AccessForAll Metadata (IMS AccMD) Information Model : aims for metadata that expresses a resource’s ability to match the needs and preferences of a learner’s AccLIP profile. It is intended to assist with resource discovery and also provides an interoperable framework that supports the substitution and augmentation of a resource or resource component with equivalent or supplementary components as required by the accessibility needs and preferences expressed in a learner’s AccLIP profile. – The IMS Guidelines for Developing Accessible Learning Applications: is a set of recommendations and resources for making e-learning accessible to people with a range of disabilities. • This work has been now integrated into a new international ISO/IEC standard under the overall title of ISO/IEC 24751 “Individualized Adaptability and Accessibility in e-Learning, Education and Training” published 16-9-2008.

Sampson CAVA 2011, Bogota, Colombia, November 2011 Research Unit on Advanced Digital Systems and Services for Education and Learning (ASK) ISO/IEC 24751-1:2008 “Individualized Adaptability and Accessibility in e-Learning, Education and Training” is intended to meet the needs of learners with disabilities and anyone in a disabling context. ISO/IEC 24751-1:2008 provides a common framework to describe and specify learner needs and preferences on the one hand and the corresponding description of the digital learning resources on the other hand, so that individual learner preferences and needs can be matched with the appropriate user interface tools and digital learning resources.

Sampson CAVA 2011, Bogota, Colombia, November 2011 Research Unit on Advanced Digital Systems and Services for Education and Learning (ASK) eAccess2Learn Conclusions 1.0 • Tools to empower the different actors in Accessible Technology Enhanced Learning (AccTeL) for their various capacities are needed. • It is important in Accessible TeL to adopt and possible enhance widely spread international Learning Technology specifications (such as IEEE LOM and IMS Learning Design), so as to be able to include accessibility requirements of people with disabilities in large scale TeL business cases. 24/40
  • 25. University of Piraeus Department of Digital Systems Centre for Research and Technology – Hellas (CE.R.T.H.) Informatics and Telematics Institute (I.T.I.) D. G. Sampson CAVA 2011, Bogota, Colombia, November 2011 Research Unit on Advanced Digital Systems and Services for Education and Learning (ASK) eAccess2Learn Conclusions 1.0 To this end, the adoption of the IMS Learning Design as the enabling specification for the formal machine-readable description of e-learning activities is very important, so as to be able to inter-exchange them between different platforms. There are several benefits from this design decision: – e-Learning activities designed for learners with disabilities will not be isolated from other e-Learning activities – Different e-learning service providers can deploy and re-use e-learning activities from common pools (such as repositories with e-Learning activities in the form of Learning Designs) – e-Learning activities designed for learners with disabilities can be inter- exchanged between different e-training systems and platforms 25/40
