A rather grand title for an Advance article I hear you say. However, I believe we’re covering a grand topic –
accessibility – which has two things in common with the cries heard in 1789. Firstly, it promises to free our content,
making it accessible to all. Secondly, the term has different meanings to many people and is implemented in various
ways.
The title of the article is where the fancy stuff ends. This article is a practical introduction to accessibility for
e-learning projects. It’s designed to help developers, designers and project managers understand the key issues
involved and the practical steps that they can take to make their content easier to use, easier to understand and more
engaging. Drawing on many years of experience, the article also features the thoughts of the only team to have won
the e-Learning Age award for ‘Care Taken to Achieve Inclusivity in an e-Learning Programme’.
So, why worry about accessibility?
Advance, © Saffron Interactive 2009
Recent research conducted by CSR Europe indicates that as many as 20 per cent of people have a disability that may
interfere with the use of a computer for educational purposes. This means that a huge population could be taking
e-learning courses but not getting the best out of them. It could mean that one in five members of your team take an
e-learning course but don’t really benefit from the experience, risking non-compliance, frustration, anxiety and lost
productivity. Even if you acknowledge and accept this, the truth is that e-learning that’s designed to be accessible
tends to be more effective for everyone. Bottom line, accessibility matters!

4. Ongoing testing for
accessibility
When building an e-learning course, your process should
allow for frequent accessibility testing. The earlier you find
an issue, the easier it will be to fix. A number of tools are
available to help you with this process at
http://www.w3.org/WAI/ER/existingtools.html.
However, we have found that accessibility testing needs
human intervention; it can’t be simply driven by the tools.
As the folks at Skills for Access2 say ‘accessible e-learning is
achieved by engagement, not by formula.’ We always use a
diverse pilot group of end users who test various aspects of
the accessibility and the usability of our courses. In the past,
we have found that although our courses are technically
accessible, they’re not very usable and this creates a barrier
to real accessibility. We therefore try to have members
of this group available to our designers and developers
throughout the development process so that we can test for
accessibility all the way through a build.
Finally, it’s useful for developers to have access to tools such
as JAWS3 – a screen reader that is used by many people
who have a visual disability. It works by reading out the text
on each page and, although designing courses to comply
with JAWS and other screen readers takes some thought,
this enhances the usability of courses for everyone.
1789 and all that!
In conclusion, if you are building e-learning content, you
have the opportunity to make it effective for the majority
of the population – don’t pass this chance up, free your
content!
Building accessibility into your e-learning course should
be a matter of best practice. Intelligent design, proactive
Advance, © Saffron Interactive 2009
engagement and the appropriate use of the tools available
will ensure that not only is your content available to a
diverse group of people but that it delivers this content in
the most usable form possible.
