Inclusion and online learning opportunities: designing for accessibility Efaine J. Pearson* and Tony K o p p i * * *Special Needs Computing Research Unit, University of Teesside **Director, Educational Development and Technology Centre (EDTeC), University of New South Wales email: e.pearson@tees.ac.uk, tkoppi@unsw.edu.au Higher education institutions worldwide are adopting flexible learning methods and online technologies which increase the potential for widening the learning community to include people for whom participation may previously have been difficult or impossible. The development of courseware that is accessible, flexible and informative can benefit not only people with special needs, but such courseware provides a better educational experience for all students. This paper discusses an evaluation of WebCT in practice at University of New South Wales (UNSW). The objective was to assess the accessibility of WebCT for people with disabilities - sensory, cognitive and physical. The guidelines provided by the World Wide Web Consortium (W3C) (Web Content Accessibility Guidelines 1.0, http://www. w3.org/Tr/WAI-WEBCONTENT), checking mechanisms including the Bobby Web page analysis tool, developed by CAST (http:llcast.org/bobbyl), and learner centred design methods provided the basis for the evaluation. The approach involved extensive evaluation of existing courses by the researcher, discussion with and survey of WebCT designers, and the involvement of students with disabilities through interview and focus groups. Issues considered include: the provision of alternative information; structure, presentation and organization of content and navigational elements; and accessibility with assistive technologies. The results reveal that many barriers to accessibility can be overcome through awareness of design issues, and that there is a need for practical advice for academics. The aim is to present a case study of best practice in the design of accessible courseware incorporating design strategies that will enable students with various disabilities to take advantage of the 'just in time, just for me' approach. 17 Elaine J. Pearson andTony Koppi Inclusion and online opportunities: designing for accessibility Introduction Developments in online learning can present opportunities for a more inclusive education for students with disabilities. Online learning facilitates real flexibility in the time and place for learning; independence is increased through the availability of online learning resources, and there is less reliance on the assistance of helpers such as library staff or note-takers. The ability to submit work electronically can release the students from the costs in time and resources in obtaining physical access. Communication can be improved - computer technology can give voice to those without, both literally and figuratively. Communication devices such as chat rooms, discussion groups and email can enable students to participate without prejudice or embarrassment. The same developments, however, can also pose further barriers to those with disabilities. Web-based learning materials tend to be heavily text-based, and students may have difficulty in reading or comprehending text or distinguishing colours. Many have difficulty with organization, structure or memory, they may find material difficult to navigate, poorly structured or complex, or the interface may be inconsistent. Students with mobility problems, limited motor control or vision impairment may not be able to use a keyboard or mouse. The increasing use of multimedia can be beneficial in providing an enriched environment, but it can also be a barrier to those who cannot see or hear audio, video and animations. Furthermore, the growth in overseas students and distance learning means that there are increasing numbers who may not be fluent in the language of instruction. The trend towards development of courses and resources online with the support of a virtual learning environment (VLE) such as WebCT and Blackboard presents both opportunities and challenges in the creation of flexible, informative and accessible educational materials. Part of the challenge is to provide opportunities to the individuals of a wide and varied community, some of whom might not otherwise be able to participate in higher education. People with disabilities face particular barriers to inclusion and the move to online learning may facilitate the lifting of some of these barriers. There is an increasing awareness of the need to make Web sites accessible to everyone regardless of ability/disability, with a legal imperative coming from the Disability Discrimination Acts in the United Kingdom (http://www.disability.gov.uk/index.html) and Australia (http://www.deet.gov.aularchiveliaelanalysislddaedcon.htm), and the Disabilities Act (http://www.wrightslaw.com/info/section504.ada.peer.htm) in the United States. Guidelines, including Web Content Accessibility Guidelines 1.0 (W3C), and 'Web accessibility resources: quick tips to make Web sites accessible' (http://genasys.usm.mame. edulaccess.htm) exist to aid developers of Web sites, and an increasing number of sites display the 'Bobby Approved' logo. However, learning environments and resources for online teaching have other requirements for accessibility beyond functional considerations and the use of 'ALT' (alternative text) tags. Care needs to be taken with the navigation, structure, content design and communication aspects, and learner-centred design is crucial to ensure that online learning is accessible to students with disabilities. Most discipline-based academic course developers are stretched to keep abreast of technical developments. Often online courseware development is carried out in addition to their normal workload and they have little time to learn programming skills or understand the technical terminology used in many of the guidelines, such as those provided by W3C. 18 ALT-J Volume 10 Number 2 Teaching with technology is not something that can easily be picked up along the way as something to be done off the side of the desk while engaged in more important or time- consuming activities such as research. (Bates, 2000) Additionally, many of the existing guidelines (Leung, Owens, Lamb, Smith, Shaw and Hauff, 1999) lack practical examples for implementation and are themselves too technical to be easily followed and understood by academic courseware developers. Furthermore, the guidelines tend to concentrate on the functional aspects of Web design and the needs of users with sight or physical impairments, while there is a lack of attention to the needs of people with cognitive or learning disabilities. The guidelines also fail to address learner- centred design of online courseware. There is also a paucity of advice available specifically aimed at the design and development of accessible educational courseware for academic developers. A set of guidelines was required which are specifically tailored to learning and teaching in higher education and to Web-based learning resources in particular. These guidelines needed to incorporate details of potential barriers to access, practical examples for implementation of accessible solutions and reference to the related W3C guidelines.. This paper presents a case study of best practice in the development of courses in WebCT (and also has generic application), taking account of the needs of people with a wide range of special needs. Rather then focus on particular categories of disability, the approach is to consider the components and design issues concerned with the development of courseware in terms of the difficulties that students with disabilities might face in accessing them. Addressing those issues has provided a blueprint for online courseware development that represents not only a design strategy for people with special needs but is equally applicable to learner-centred courseware design in general. The partners This project is a collaboration between the Special Needs Computing Research Unit (SNCRU) of the University of Teesside and the Educational Development and Technology Centre (EDTeC) of the University of New South Wales. It has been supported by a Study Abroad Fellowship from The Leverhulme Trust, UK. Members of the SNCRU have carried out extensive research and development in the application of computer technology for people with physical and learning disabilities and the senior author of this paper provided the research expertise in this area. Current research interests within SNCRU include development of a symbols-based managed learning environment for students with severe disabilities; assessment, remediation and development of language in children with special educational needs; and investigation of Autistic Spectrum disorders. The Educational Development and Technology Centre (http:llwww.edtecunsw.edu.au) provides services in the promotion and development of institution-wide support for online learning using WebCT. Part of EDTeC's remit is to investigate means of making education more accessible, through technology, to people with disabilities. The centre's support enables teaching staff to develop online learning environments for themselves. As of March 2002 there were more than 600 courses online with more than 21,000 students enrolled on those courses. 19 Elaine }. Pearson and Tony Koppi Inclusion and online opportunities: designing for accessibility Some definitions Accessible design in this context refers to the means by which the content and presentation of an online educational experience enables participation by every student regardless of the browser, browser settings or assistive technology they may be using. The goal should be to enable, as far as possible, the same educational experience for everyone. One should recognize, however, that it may be impossible to cater for all needs, all of the time, but care needs to be taken to provide alternatives when particular needs cannot be met. Assistive technology can be defined as devices, tools, hardware or software that enable people with disabilities to use the computer. Screen readers, screen magnifiers, alternative keyboards or input devices, voice recognition software and text-only browsers are some of the main examples of assistive technology. Inclusion refers to the design of educational environments to take account of the needs of all learners, providing access to a learning experience at a pace and level to suit the learner. Online learning presents opportunities for more inclusive education through the 'just in time, just for me' approach - offering flexibility in the time, place, mode and pace of learning (Collis and Moonan, 2001). Evaluation methodology As part of its mission to encourage inclusive practices in educational development, EDTeC aims to encourage staff developing courses in WebCT (designers) to attain, in the first instance, compliance with Priority Level One of the W3C Web accessibility guidelines. Priority One means that the designer is satisfying the basic requirements for access to Web documents (W3C). This is in line with WebCTs own stated aim (WebCTand Accessibility, http:llwww. webct. com/service/). In order to identify the accessibility problems related to the design of courses delivered through an online learning environment, and to propose solutions, an evaluation was carried out of existing courses at UNSW, with the consent of the designers concerned. The process involved a combined qualitative and quantitative approach including: • extensive evaluation of WebCT courses developed at UNSW; • discussion with and survey of designers; • interviews with students with disabilities; and • practical evaluation by students of the accessibility of courses using assistive technologies. The evaluation was based on the guidelines provided by W3C 'Web Content Accessibility Guidelines 1.0'; analysis of the courses using the Bobby Web site validation tool; testing with other available checking mechanisms (for example, graphics turned off and monitor set to high contrast); and also with regard to courseware design methods. The W3C guidelines are produced as part of the W3C Web Accessibility Initiative and provide a guide to ensuring the accessibility of functional aspects of a Web site. There are fourteen guidelines or general principles, each with a set of checkpoints, and the rationale 20 ALT-] Volume 10 Number 2 behind each guideline. Web Bobby is a tool which provides a crude but indicative analysis, allowing the designer to check the extent to which their courseware has met the criteria of the W3C guidelines. However, evaluation of a learning environment which takes account of the requirements of those with sensory and learning disabilities also requires analysis of the structure, presentation, content and navigational aspects. For this the principles of learner-centred courseware design (Figure 1) were employed. A model of courseware design that combines content design, navigational design and visual design but is informed at all stages by the learner model (Pearson and Green, 1999) is the one on which this evaluation is based. Briefly, the model incorporates content (design of learning materials and activities), navigational design (flow of control and structure), visual modelling (user interface, icons, graphics) and, crucially, learner modelling (who the learner is, what the learning needs are, how the learner will learn, the aims and learning objectives).
