Could on-screen narration be discriminatory?

Posted on by

Cathy Moore has an interesting blog post entitled “Should we narrate on-screen text?, where she suggests that automatic narration of on-screen text can actually be detrimental to learners. She states that learners generally read more quickly than the narration is read – screen reader users can “read” text very quickly -and that learners are then forced to move at the pace of the narration.

Although some learners may find on-screen narration useful such as young children, learners who are learning the language of the learning resource, and learners with low literacy skills or cognitive difficulties, on-screen narration should not be included just to try and fulfil obligations towards students with disabilities. Automatically including on-screen narration just to fulfil SENDA (Special Educational Needs and Disabilities Act) obligations, could actually discriminate against students who do not need on-screen narration.

Therefore, the provision of on-screen narration should be considered very carefully and, if it is considered necessary, offered as an alternative or option, but the original resource (or an alternative) should still be accessible to screen reader and other technology users.

Keeping it Legal – The Complementary Approach to Accessibility

Posted on by

Following on from my post One Person’s Strategy is Another’s Barrier, where I talked about using complementary approaches to e-learning resource accessibility, Becta’s Making Software Accessible: A Guide for Schools (PDF format, 468Kb) helpfully provides a summary of the legal requirements in the UK (United Kingdom) surrounding the provision of e-learning resources. One of the points states that:

“…use of an ICT [Information Communication Technology] with an accessibility barrier is not necessarily unlawful under the DDA [Disability Discrimination Act], so long as:
* Existence of the barrier is justifiable on academic, technical or financial grounds; and
* The educational organisation using the ICT provides equivalent alternatives to allow affected disabled people to reach the same learning objective as provided by the inaccessible ICT.

Where a barrier exists and can be justified on the grounds specified… above, information about the justification should be provided by the ICT producer and used by the educational organisation to inform provision of suitable alternatives.” (Becta (2007). Making Software Accessible: A Guide for Schools. Accessed 12/09/07.)

Perhaps it would be helpful if all resources were marked with metadata which described what a learning resource consisted of.  So for example, a Flash animation with captions could be identified as having audio, visuals, and captions.  This would help learning technologists and learning resource providers to provide alternatives to students.  The IMS AccessForAll Meta-data Specification provides a way of marking up e-learning resources with metadata which describes their modality – e.g. “hasText”, “hasAudio” etc.  A simpler format has also been developed by TechDis – the Accessibility Passport.  This idea allows content creators, tutors, and students to describe the accessibility of a resource in the form of a passport which travels with the resource (perhaps in the form of an online web page).  For example, a content creator describing a Flash animation could state that it is in English, with audio, visual and captions.  A student might then comment to say that there is a time lag between the animation and the captions or a tutor could leave a comment to say that it had been translated into German and its location.  Another content developer might comment that an alternative resource for the same learning objective had been developed for visually impaired people.  (Obviously, I’m not going into IPR (Intellectual Property Rights) here or the actual technical logistics, but hopefully you get the idea!)  It would also help to “inform provision of suitable alternatives” as mentioned above.

However, provision of alternative resources must still be accessible by students or further alternatives provided – as mentioned in my last post: one person’s strategy may be another’s barrier.

One of the issues with UK accessibilty legislation is that there is no technical definition of what constitutes an accessible e-learning resource or a “reasonable adjustment” as described in SENDA (Special Educational Needs and Disability Act, 2001).  Guidelines such as those developed by W3C WAI (World Wide Web Consortium Web Accessibility Initiative) have been accepted as de facto standards but they are not designed for e-learning and the UK government has not stipulated that they must be used.  Most developers do so voluntarily.  One of the main disadvantages is with the lack of technical definition is that developers can often feel as though they are “feeling their way” with accessibility.  On the other hand, there are distinct advantages.  By not defining a technical definition of what constitutes accessibility, developers are given free rein to produce solutions which, whilst perhaps not strictly conformant to the various guidelines, are actually accessible.  Also, innovation is allowed to flourish – such as in the form of the new Web 2.0 technologies – and give rise to new ways of working and approaching accessibility and learning.  Again it is the one size fits all versus holistic approach, but rather than seeing them as conflicting approaches, they should be considered as complementary.

So what approach needs to be taken to ensure that one is legally compliant?  The answer is easy: work alongside current guidelines and provide equivalent alternative resources, where necessary.  In other words, do as much of the generic accessibility as you can (such as making sure your HTML (HyperText Markup Language) validates) and provide alternatives as necessary, where this isn’t possible (e.g. provide a transcript of a podcasted lecture for students with auditory impairments or without access to speakers).  Straightforward in theory, but in practice…?

Jumping Through Hoops – Reasonable Adjustments for Exams

Posted on by

The DRC (Disability Rights Commission) are currently supporting a legal case brought about by a student, who claims that she was discriminated against when taking an online exam for a professional qualification.  The complaints include one about unreasonable demands for evidence of disability, and one about requests for reasonable accommodations.

Hoop 1: Prove Your Disability

The SENDA (Special Educational Needs and Disability Act) states that educational institutions must make reasonable adjustments for disabled students in order to avoid substantial disadvantage.  However, in order for those reasonable adjustments to be made in the exam room, many institutions need actual evidence of disability. For those students who are known to their educational institution, evidence may not necessarily mean a medical certificate, as a tutor’s or other adviser’s statement may be enough. 

However, in the legal case mentioned above, the professional body running the assessment had not actually met the student as most of her studies were completed electronically.  So in this case, actual medical proof was their only recourse to evidence of disability, before any special accommodations could be made.  Including a suite of preferences as part of the test software could have helped with some of the accommodations the student required and may even have avoided the need for the provision of evidence of her disability.

Hoop 2: Take the Test the Hard Way

In the legal case mentioned above, the student was not allowed to take her own laptop into the exam room nor was she allowed to use a screen reader to access the test, because the professional body felt that installation of software from outside their test suite could put the security of their test at risk.

In this case, both parties’ requests could be considered as reasonable – the student’s request for additional software in order to take the test and the testing body’s refusal on the grounds of security.  Security issues around assessment are a common fear.  If an exam body wants to keep the quality of its qualifications high, then security will be paramount.  But where does this leave the student who needs additional software in order to access the test?  In this case, the student was offered the services of a reader and extra time – it was not an ideal solution for her, but was one with which the testing body was happy.  This is probably not an isolated incident – there are no doubt many conflicts between what the student really needs to take an online test and with what the testing body feels comfortable about allowing the student to use.  Compromises are made, but perhaps it is the student who always ends up with the worst deal.

Levelling the Playing Field

So would it be worthwhile for test centres (and maybe other online test providers) to provide generic accommodations?  Offering a text reader or screen magnification software as part of the test software suite could remove the need for some students to provide evidence of their disability and could reduce the worry for exam bodies about compromising security. 

Screen readers, for example, are a common type of assistive technology and come in various shapes and sizes.  Although it would be impossible to provide screen readers to suit everyone’s needs, it might be possible to provide one cut-down or authoritative version simply to allow students to access online assessments, as long as the student was allowed to practise using the technology well in advance.  This could keep costs down and possibly improve a student’s interaction with the test software, if practice runs have been made available.

Availability of such technology would also depend on the type of test being undertaken but for online exams, where reading the questions aloud did not defeat the actual purpose of the question, providing access to even one type of assistive technology could go a long way to including rather than excluding people.  Of course, the questions would also need to be screen reader-friendly and alternatives to questions containing graphs or images may need to be offered, but providing accessible and/or alternative questions may benefit all students.

I’m not saying that one size should fit all.  Many disabled students will still need to use their own particular type of technology but including some common types of assistive technology in a test software suite could help level the playing field.  In an ideal world, students would be able to set their own preferences, use their own software and even have assessments based on their particular learning styles. 

Above all, it is imperative that exam bodies and educational institutions who provide online tests are clear about what is actually being tested (is it the student’s ability to interact with the test software or their knowledge and understanding of a particular subject?) and to ensure that any assessment clearly reflects that goal in a user-friendly and supportive manner.  After all, assessment in any form is usually stressful enough without having to jump through extra hoops.
