Introduction
The challenge of making online resources and activities accessible can appear daunting. Staff may feel overwhelmed by guidelines which can appear overly technical to them, or they may be deterred from using online resources for fear that these could be inaccessible. However, it is important to remember that at the most basic level the online environment increases accessibility as it allows more information and resources to be made available to more people.
The main purpose of this guide is to provide a number of practical suggestions for ways in which online learning resources can be made more accessible. It suggests some potential benefits of e-learning not just for those with disabilities but for all students. It is not a checklist for accessibility, but hopefully will help raise awareness and encourage consideration of a “universal design” approach, which aims to make things more accessible for all.
What is web accessibility?
“Web accessibility is about ensuring your website can be accessed and is usable by the largest audience possible, regardless of disability or browsing technology.”
(AbilityNet, Web accessibility – an introduction , http://www.abilitynet.org.uk/webarticle24 )
The legal background
What the law says:
The key points of the Special Educational Needs and Disability Act (SENDA) (Part 4 of the Disability Discrimination Act (DDA)) are as follows:
- “An education institution should not treat a disabled person ‘less favourably ‘ for a reason relating to their disability.
- An institution is required to make ‘reasonable adjustments ‘ if a disabled person would otherwise be placed at a ’substantial disadvantage ‘.
- Adjustments should be ‘anticipatory ‘.
- The legislation applies to all admissions, enrolments and other ’student services’ which includes assessment and teaching materials.”
(Techdis, http://www.techdis.ac.uk/index.php?p=3_12_21)
Who is defined as disabled?
“Someone who has a physical or mental impairment that has a substantial and long-term adverse effect on his or her ability to carry out normal day-to-day activities.” http://www.direct.gov.uk/en/DisabledPeople/RightsAndObligations/DisabilityRights/DG_4001069
Further information is available from the Disability Rights Commission: http://www.drc-gb.org/the_law/legislation__codes__regulation/keypoints.aspx
Categories of disability
The Act includes people with physical or mobility impairments, visual impairments, hearing impairment and dyslexia.
How can e-learning increase accessibility?
e-learning approaches and/or online resources can be beneficial to students with disabilities, but also others, in a range of ways:
1. Resources online:
- offer increased flexibility as students can access them at a time, place and for a duration convenient to them.
- can be richer through incorporation of diagrams and the careful use of colour.
- can be hyperlinked to further explanatory or extension materials.
- can be increased or reduced in size by each user
- can be customised by individual learners to meet their own preferences, e.g colours and font style.
- can, in the form of text, in many cases be read by appropriate software.
- can be provided in alternative formats, e.g. audio.
(Techdis “Accessible e-learning” staff pack at http://www.techdis.ac.uk/resources/sites/staffpacks/Staff%20Packs/Accessible%20Learning/Presentn%20eLearning.xml#maincontent )
2. Advance provision of lecture support materials can help students to prepare for face-to-face sessions, for example by familiarising themselves with terminology and concepts.
“This is particularly helpful for some disabled students who have problems with reading or writing speeds, as a skeletal structure of the lecture will afford them more time to listen and understand”. (http://www.dur.ac.uk/alert/guidelines.htm )
3. Online communication tools offer a means for support and discussion with both lecturers and/or peers.
4. Online collaborative working can be used for group work and problem-solving, which can help foster a sense of community and peer support, as well as reducing the sense of isolation felt by some students.
5. Online assessment tools can offer timely feedback, convenience, flexibility (allowing students to work at their own pace) and contribute to a balance of assessment methods.
Accessibility and the Virtual Learning Environment (VLE)
The following extract introduces some of the issues around accessibility and Virtual Learning Environments, such as Moodle. It is from an article on the Techdis website. Techdis (www.techdis.ac.uk ) is a leading educational advisory service, funded by JISC, which works across the UK, in the fields of accessibility and inclusion.
“Whatever the specific accessibility pros and cons of a particular Virtual Learning Environment (VLE), anything that facilitates making content available to learners in digital formats is a potential accessibility gain because digital formats are generally more flexible than most traditional formats …. The accessibility of any learning experience is also affected by the provision of support – either tutor to student or peer to peer. Good support can negate accessibility difficulties whilst poor support can add to them. Once a learner is logged in to the learning environment there are further layers of accessibility
1) the accessibility of the navigation
2) the accessibility of the content (both technical accessibility – “does this image have a description for a blind user?” and cognitive accessibility – “do contour map descriptions make sense to a blind user?).
… Finally, the accessibility of learning experience itself is part of the mixture. If the learning experience is active and engaging, learners have an incentive to work around accessibility barriers. Dull learning experiences demotivate and create their own accessibility barriers.”
(Techdis , http://www.techdis.ac.uk/index.php?p=3_10_6_2 )
A series of useful guidelines and case studies on accessibility in Learning environments and related technologies are available on the ALERT website (http://www.bournemouth.ac.uk/alert/index.html).
The University of Bath offers a range of e-tools to give flexibility in meeting the needs of staff and students. The VLE Moodle is currently one of the most widely used applications, so the following guidelines have been drawn up to help staff make their Moodle courses more accessible. Many of them, however, can equally be applied to other online learning environments, including static web pages.
What can I do to make my Moodle course more accessible?
Some aspects of accessibility (e.g. some navigation) relate to the Moodle application itself. However, as editors of Moodle courses, staff have control over what resources and/or activities are added, how they are written and presented, and what support is available. In these areas they can make a significant difference to accessibility. The following is not a comprehensive or definitive list, merely some suggestions. As mentioned previously, much of the following advice can help make resources more accessible to all students not just those with specific disabilities.
General advice
- Ensure that information is up-to-date.
- Use consistent navigation and logical structure in and across your courses.
- Put key information and instructions at the top of the page. For anyone using a screenreader it would help for key information to be shown in the top left block of a Moodle page, for example in a course summary block.
- Ensure tasks are clearly structured and explained.
- Use clear headings.
- Ensure links, documents and folders are labelled meaningfully (N.B. If using folders in Moodle make sure the files you have uploaded are clearly named, and if necessary rename them).
- Avoid empty folders or topics. Keep them hidden until they are populated.
- Ensure web links are up-to-date. Delete or update any “dead” links.
- If you choose for web links or documents to open in a new window, make sure that this is clearly indicated.
- Arrange for students to have an induction on using the VLE for their particular unit/programme.
Advice with regard to specific types of disability
For an overview of specific disabilities see the Techdis section on Disabilities at http://www.techdis.ac.uk/index.php?p=9_2 . The Simdis website contains simulations of various aspects of disability, and are intended for awareness-raising. (http://www.techdis.ac.uk/resources/sites/2/simdis/index.htm )
Colour blindness
- Ensure text is well-contrasted against the background.
- Avoid distracting background images.
- Avoid colour-dependant navigation, e.g. “Click on the green button.”
- Avoid using colour alone to convey meaning. If colour is used consider adding a textual cue as well. For example it is common practice to highlight quotes in a different colour in online discussion forums. Adding speech marks and/or the quoted person’s name in brackets provides additional textual clues.
Mobility and/or Motor impairment
- Provide tests or quizzes in alternative format if limited dexterity would affect a student’s ability to answer, for example drag and drop questions in Hot Potatoes.
- Allow students ample time for completion of activities e.g. quizzes
- Avoid making hyperlinks too small. The smaller a link, the more difficult it will be for someone with limited fine muscle control to click on it.
- Use online announcements in the News Forum to let students know in advance of changes to face-to-face schedules.
Visual impairment
- Provide quick and easy navigation to activities and resources. For the benefit of screenreader users it may help to place the activities block near the top left of the course where it can be accessed quickly.
- Always provide alternate text for images.
- Provide tests in alternative format if questions rely on image recognition. Use alternate text if this can convey the sense of the image without giving away the answer.
- Ensure that any documents you upload are accessible (see section on “Creating accessible documents” below for further information).
Hearing impairment
- Provide a transcript as an alternative to any audio used.
- Consider providing synchronized captions or a transcript for video. People who are deaf need this if the video does not make sense when the sound is turned off.
Dyslexia
- Place salient points first.
- Use clear, concise and simple language. In discussion forums, for example, use meaningful and clear subject headings for discussion threads.
- Break content down into bite-sized chunks e.g. by using bulleted points or numbered lists.
- Choose an appropriate font. Techdis recommend the use of sans serif fonts such as Arial (Helvetica) or Comic Sans. Other suggestions include Verdana, Georgia, Tahoma and Trebuchet MS.
- Allow ample white space on the page.
- Avoid using justified text.

Making webpages accessible
Resources added to or created in Moodle can be in the form of webpages. Moodle has its own web editing toolbar which allows staff to create pages of content. For general guidelines on making web pages accessible see the University Web Publishing Accessibility Guidelines: http://www.bath.ac.uk/web/guides/accessibility
