What would you change about the way in which students are supported in your institution and why?

At least four post-secondary groupings have a stake in accessibility and e-learning in colleges and universities:

1. students
2. service providers
3. professors
4. the e-learning professionals on campus.

All four groups indicated, via online questionnaires, problems with:

• accessibility of websites and course/learning management systems (CMS)
• accessibility of digital audio and video
• inflexible time limits built into online exams
• PowerPoint/data projection during lectures
• course materials in PDF
• lack of needed adaptive technologies.

Fig.1. Fitchen et al (2009) Table 5

When it comes to e-learning problems and solutions the nature of students' disabilities and impairments can have an important impact. Therefore, in Table 5 we present the most common problems and solutions for students with different disabilities.

This shows that the most popular solution for students with all types of disabilities is unresolved.

For most groups of students, solving e-learning problems by using non e-learning solutions was also popular. In addition to the common problems of inaccessibility of websites and course management systems and technical difficulties, which seem to pose problems for students regardless of the nature of their disability, students with learning disabilities and students with mobility impairments and arm/hand issues also had problems due to their lack of knowledge about how to use e-learning effectively. Students with psychiatric and with health issues noted problems due to poor use of e-learning by professors. Students with hearing impairments, not surprisingly, had problems related to the accessibility of audio and video materials. Students with visual impairments had problems related to the accessibility of course notes and materials, especially those in PDF. When their problem had a solution it was through non e-learning solutions, such as having someone read the materials aloud to them or through alternative formats or using adaptive technologies. (Fichten et al 2009:249)

Recommendations

Training

One means of addressing problems involving inaccessibility of websites and course management systems, of elearning broadly, and of specific materials, such as course notes and audio and video clips is through training of professors. Many colleges and universities already offer training on how to integrate e-learning in teaching and on how to use specific e-learning tools. (Fichten et al 2009:253)

Designing and developing accessible e-learning experiences: the learning technologist’s perspective.

1. There is a debate surrounding who is responsible (or most responsible) for accessibility. How helpful is this debate in ensuring that people working in post-16 education change their practices?

   If those with technical skills, such as learning technologists, are not ultimately or solely responsible for ensuring accessibility, what responsibilities do you think they should have and why?

2. On pages 82–83, Seale uses an archaeology metaphor to try to encourage learning technologists to dig deeper beneath the surface of accessibility guidelines and standards. This is intended to develop a greater understanding of approaches to accessible design. How helpful do you think this metaphor is?

   'Using archaeology as a metaphor, it can be argued that accessibility legislation, guidelines, standards and evaluation tools are not the most helpful or informative place to start. The legislation, guidelines, standards and tools are merely archaeological artefacts that have been scattered on the surface of a significant archaeological site'. Seal 2006:83

   This doesn't work for me. It doesn't ring true to the metaphor. a) Archeology implies something ancient and long buried whereas these guidelines are 'scatterd on the surface' like rubbish dropped at a later stage. The rules and regulations are recent and changing, both in what is said, how interpretted, executed and policed.

   Can you think of an alternative metaphor, image, analogy or visualisation that could be used to help develop learning technologists’ thinking in this area?

   Not only is collaboration in learning coming of age it needs to happen in practice, as increasingly it does in industry. There continues to be a good deal of resistance in higher education, partly this is because of how academics in particular came into managerial positions - if they are. My experience of most academics is that either they want to be left alone to do research, or they want to be left alone with their students - they didn't chose to 'go into business' or join the 'real world' because of the stresses in relation to managing tasks such as this and working in a team where they might not be top dog. It would help enormously if those in Higher Education could spend some time working in business and to take these models and employ them on in their department of faculty. For a start, take on roles such as project manager, learning designer, lead programmer, art director, author and so on. Then find a metphor that works for everyone that evokes both team work and organic growth. A rock band works for me - I resist the orchestra analogy as it is such a cliche and leads to some people wanting to be the conductor or composer. A theatre troupe might be the thing. Or a circus act! But all performing together and dependent on each other. Academics in particular most stop behaving like premadonnas - 'out here' they are the 'subject matter expert' - less than a writer, just a conduit for knowledge, a talking and responsive version of information that is readily available online anyway. i.e they can be a hinderance. Perhaps the metaphor I would use, which is close to the reality of creating interactive content - would be a film production unit where there are specialists skills, and a hierarchy: executive producer, producer, line producer, director, first assistant director, camera operator, sound engineer, actor 1, actor 2, script writer, script continuity, art director, props, costume ... editor, publicity and so on. One weak link and the entire project might fail.

   As it has currency in learning and e-learning circles an even better metaphor might be that of an architect's studio given the way in which e-learning has to be designed, constructed in a programmer, shared, adjusted, tested, built, tested again, added to with various layers from foundations to walls, pluimbing and electrics, then internal and external decor and furnishings. Christopher Alexander's 1970 book 'The Timeless Building' which he developed into a methodolgy for computer software design is often cited.

3. On page 98 Seale discusses the tensions regarding the use of technical tools versus human judgement to evaluate the accessibility of learning resources. What is your position concerning this issue? Can we trust human judgement? If so, whose judgement should we trust – learning technologists working within educational organisations or external experts?

We have to trust human judgement, which includes the decission to expect the technology to provide the answers, or do the donkey work. Instead of relying on one piece of software to come up with a myriad of answers that to the uninitiated can look like some task set by a wicked wizard in a fairy tale. I'm in favour of having a large and diverse testing team drawn from a community of learners, including of course those with visual, hearing, mobility or cognitive impairments - to offer opions - as we have reviewers and editors in things like Wikipedia. i.e. use the power of the numbers online rather than simply the power of a piece of software.

Make brief notes in response to these questions. Your notes should reflect your own context. You can do this as bullet points or just a sentence or two about each question.

Choose one of your answers and post it for discussion in your tutor group forum. If you disagree with Seale about any of the points in this chapter, you could also discuss this in the forum.

2 HOURS

My background is corporate communications where our projects are produced by a team - in advertising an art director works with a copywriter, in web design we added a programmer and for e-learning we added a learning designer and subject matter expert - in education the teacher or tutor is this subject matter expert and at the most senior level is expected to do it all themselves.

I don't get this at all - we know that people have different strengths and weaknesses. There is a particular divide betgween those who can write and those who can visualise, between the author and illustrator, the copywriter and art director.

The result from too many teachers and tutors is either little online presence or a blog, sometimes a power point presentation.

I find resistance and unwillingness repeatedly and have sympathy because they should not be expected to do much other than be brilliant exponents of their subject.

They are rarely good at visuslisation or narrative, have had no training on use of slides so pack 'em full of words or irrelevant clip art and by habit write blog posts that are too long, too dense and too late. They hate to let go of their idea - it is theirs and no one else may touch or influence their brilliant conceptions.

I've given Xerte a go.

I have many users in mind for the content that only it can deliver - but in my case I know when I am stumped and if it feels like I'm having to conjugate verbs in Latin I'll go and find someone who can make it sing.

On my list of tools that promise a lot but fail, Xerte may escape this category for now, I inlcude Elluminate, Compendium, MyStuff and Cloudworks and Social Learn. They all have something in common.

I'll give Xerte another go as I see what I can deliver in terms of access. But as an e-learning platform it is slide show.

On the pros and cons of being both the subject matter expert and the learning designer

http://clive-shepherd.blogspot.co.uk/2012/10/do-instructional-designers-need-to-know.html

I could reach out and touch that moment I started the MAODE it feels that close ... February 11th 2010.

My last TMA. No panic. A week ago I asked for an extension thinking I hadn't had the time to get my head around the Block. And today I find I've submitted in good time.

Assembled through aggregating notes held here, in the this blog, then written up in Google Docs. I don't have Microsoft Word (indeed I don't have a PC).

On the fifth and final draft I saved out of Google Docs into word and made use of my teenage son's computer.

The word count is 3000. The first draft was 3400. Only the 3rd draft crept up to the 4000 mark as I dropped in a extra couple of paragraphs on a couple of topics I thought important. Then edit hard, dropping a few points that I'd made once and didn't need repeating just because I could add a further name into the reference list.

All referencing was in place from the start. I learnt a while back that it pays to attach all references to your notes as you go along as trying to figure out who said what and where and when later is a nightmare.

The 4th draft was printed off - a rare sight indeed to see paper coming out of my wife's printer.

Proof read, ditch a paragraph. Correct. Word Count. 170 over - trim more are delete headings and subheadings I'd lifted out of the TMA title anyway. A univeral word count up to References therefore gives 2983 words.

I used to struggle with drafts that came in at 6,000 words or more. I used to beg and hope and argue for a 10% lee-way on the word count. I could lose another 500 words in this TMA and it would be better.

How things have changed. I suppose I knew the would eventually.

So that dog will have a walk in daylight and I can think about supper.

Cheerio for now.

Fig. 1. Evaluating accessibility - H810

All of this can be multi-layered, more like petals of a rose that a poster-sized mind-map.

It is of course an iterative process too - things get shifted about all the time. Exported as a TEXT document it becomes the first draft of an assignment. At a glance I can see there are 6 or 7 main themes here, though a substantial part of my thinking will be around the ideas of usabilty and accessibility and whether universal design is more appropriate than highly focused user centred design.

I thought I could offer a PDF version here - apparently not. Clicking on it will allow a download that can then been zoomed and should remain legible.

Not an assignment, but can something like this work in a piece of work for evaluation?

1) Find an example of an online learning resource from your own context that has plenty of visual content that might need to be described for a visually impaired student.

Teaching breaststroke : symmetrical whip kick and glide, arms in front of the shoulders during the pull, head still looking no further than in front of your hands.

Coach Marlins - my swim teaching and coaching blog.

A personal resource, reflection on swimming (masters) and coaching for Mid Sussex Marlins Swimming Club.  A first step towards creating a mobile resource. Below is an excerpt from a typical morning teaching four groups - three grade groups (4.5.7) typically 7 - 11 year olds) and a disability swimming group of children and adults.

See 'The Swim Drills Books'

The introduction read here : YouTube

Grade 7 are technically superior and have more stamina and may be a little older. The ones I watch out for are the 7 year olds in with 10 and 11 year olds as they need a different approach, TLC and play.

WARM UP

• 3 x 50m warm up of front crawl and backstroke

Always giving a tip before starting them off (and accommodating the odd swimmer who is invariably late), say 'smooth swimming' or 'long legs'. i.e. reducing splashing and creating a more efficient swimmer.

1. Make sure too that there is a 5m between each swimmer.
2. 25m of Breaststroke to see what I've got and potentially adjust accordingly.

LEGS

• Kick on front with a kicker float.
• Taking tips from 'The Swim Drill Book'
• I remember to put as much emphasis on keeping the chin in.

The glide is key - this is where to put the emphasis.

• May start the 'Kick, Pull, Glide' or better 'Kick, Pull, Slide' mantra to get it into their heads.

ARMS

Standing demo of the arm stroke, from Guzman, forming an equilateral triangle and keeping the fingers pointing away.

• Will 'describe' the triangle poolside then ask what it is and what kind of triangle.
• Anything to get them to think about it a little.

• I show this as a single action.
• Other things I might say include 'heart shaped' *(upside down).
• And making a sound effect 'Bu-dooosh' as I push my arms out.

Repeat the need for a pronounced glide, even asking fo a 2 second count (one Mississippi, two Mississippi)

I support by showing images from 'The Swimming Drill Book' on an iPhone or the Kindle

Leading into the turn we do in sequence (from the shallow end):

• • Push and glide for count of 5 seconds
  • Same, then add the underwater stroke and See how far you can go.

Legs Only Drill (Advanced)

Arms outstretched above the head. No kicker float

• The whole BR transition counting 3,2,1.

2) Use the resources for this activity to help you to decide which visual content needs describing.

• The objects that need describing might be photos, diagrams, models, animations and so on.

In the resources I was impressed by the clear, logical, analytical description of some of the complex bar charts, flow charts, pie charts and others. This is how all descriptions should be. In 2010 or 2011 the BBC reviewed how weather forecasts were delivered. It was determined that they were far too flowery. A plainer, clearer approach - overview, identified the region, immediate and forecast weather. Move on. Much more like 'The Shipping Forecast' was wanted and worked better. No more 'weather-caster personalities' then. It isn't entertainment, it is information.

3) For those objects that need describing, decide what kind of description would be needed.

'Before beginning to write a description, establish what the image is showing and what the most important aspects are'. UKAAF

'Consider what is important about the photograph in the context of how the image is going to be used, and how much detail is essential'. UKAAF

In swimming, any description of these visuals should emphasise the purpose of the action, the key action in relation to the physics and physiology of the pull, the action in relation to the rules of competitive swimming.

• Keep it simple
• Get to the point
• Choose the right words

4) Choose two visual objects and write a description of each.

Kick without a float. Arm pull practice standing in water or on the side of the pool.

If you can, ask someone who has not seen these visual objects to read your descriptions. Then show them the object and the context. What was their reaction? (If you have online tools to share visual resources, ask another student in your tutor group to do this activity with you.)

5) Which aspects of this task were straightforward?

Knowing that gender is irrelevant. Putting it in context.

6) Which aspects of the task were difficult?

Care not to use terms or metaphors that the swimmer may not be familiar with if they have never seen them.

• Brevity
• Clarity

Reading text on a diagram and wanting to shut my eyes so that I can hear the description without the image. Need to use screen reader or record and play back.

'Remember that blind or partially sighted people cannot skim read, so let them know how long the description is likely to be'. UKAAF

Knowing what to leave out, being confident to leave something out then knowing how to handle it.

'It is important that information provided for sighted people is also made available to blind and partially sighted people, even if the way the information is given is different'. RNIB (2009)

An author should write with a single reader in mind - in this instance while visual impairment is the modus operandi - they are first of all a swimmer or swim teacher/assistant - so the description must be given with this in mind, which in turn defines the writing/editing process of what to put in or what to leave out.

7) What else might have helped you to do it more easily or helped to improve your descriptions?

Physically moving the student athletes arms and legs through the positions. With their consent, allowing a visually impaired swimmer lay the hands on the arms then legs of someone as they go through the movement.

• An artist's manikin or a jointed doll, male or female action figure,
• Braille embossed outline.

'However converting a visual graphic to an appropriate tactile graphic is not simply a matter of taking a visual image and making some kind of "tactile photocopy". The tactile sense is considerably less sensitive than the visual sense, and touch works in a more serial manner than vision. Therefore the visual graphic needs to be re-designed to make sense in a tactile form for blind and partial sighted readers'. RNIB (2009)

In some subjects, interpreting an image or diagram could be a key skill that students are expected to learn.

Drill-down organization

Descriptions should follow a drill-down organization, e.g., a brief summary followed by extended description and/or specific data. Drill-down organization allows the reader to either continue reading for more information or stop when they have read all they want.

Keeping this logic rather than imaging the sighted eye skipping about the page, so I imagine I am not allowed to lift the stylus from the screen ... it has to be ine continuous, logical flow. Constructing a narrative would add some logic to it as well.

10) Can descriptions be done in such a way that you are not giving students the answers?

This was an interesting and relevant point regarding humorous cartoons 'Cartoons and comic strips need to be described if necessary. Set the scene of the cartoon without giving away the joke Provide a brief overview of the image.'

The same therefore applies to 'giving the answer' - treat it as the punch line but leave it out. and like a quiz book say, 'answers on page x'.

11) What do you think your strategy would be if you can’t find a way to give a description without compromising the learning outcomes?

Script differently - this is after all a different audience - and all students are ultimately an audience of one. Perhaps all resources will become highly personalised in future?

12) How can providing descriptions be included in the workflow process of delivering an online module? (This was touched on in the discussion for Activity 17.3.)

• I liked this quotation:

"When organisations send me information in formats that I can read myself it allows me to be independent, feel informed and appreciated - just like every other customer." End-user UKAAF

From Describing images 2: Charts and graphs

• Definition of print disability
• A print-disabled person is anyone for whom a visual, cognitive, or physical disability hinders the ability to read print. This includes all visual impairments, dyslexia, and any physical disabilities that prevent the handling of a physical copy of a print publication.

So, for example, design with the language and visual centres of the brain in mind, so that the specific combination of senses that might be engaged work in favour not in conflict with the process.

For example, we can read a map (visual) while receiving instructions on its use (auditory) - as the visual and language centers are distinct.

However, as I discovered yesterday, when I tried to pass on a message to my wife verbally who was in the depths of writing a report to a tight deadline not a word was heard - her language centre was so fully occupied that she shut me out. She didn't even see me come into the room. (She did enjoy the tea and toast though).

The mind's a tricky thing - are we being too clever? We've survived tens of thousands of years without multi-media or e-learning. I reckon the most useful things I have learnt in life were watching my grandfather service a car, put up wallpaper and empty the guttes.

Educational Issues for Students With Disabilities

http://ncam.wgbh.org/invent_build/web_multimedia/accessible-digital-media-guide/educational-issues-for-student

Accessible interactive software can bring the benefits of multimedia and experimental learning to students who may otherwise be left out. Interactive learning experiences will be especially enriching for students who may otherwise have more limited experiences. Because students with disabilities may not be exposed to as wide a range of activities as other students, accessible software can contribute positively toward filling in some of those gaps.

Low-vision students, however, may still learn from a visual program, provided it is well designed. Software should allow fonts to be adjusted, provide clear contrast for objects that students must locate and manipulate, include keyboard commands to reduce mouse dependence and provide a system cursor that moves with important screen events so that magnifiers can track them.

Benefits of Multimodal Learning

Making software and digital publications accessible to students with disabilities has benefits for other students as well. These benefits are especially important for students learning English as a second language and those with reading difficulty. Accessible textbooks and software often provide multi-modal access to information, combining text with audio.

Tindall-Ford and colleagues showed in several different experiments that when information is presented in audio and visual form, performance on complex tasks is improved (1997).

J.R. Williams reviewed about 100 studies from the literature on use of multimedia in instruction and found that combining visual and verbal information can lead to enhanced comprehension (1998).

Disabilities, Functional Limitations and Accessibility Tips

http://ncam.wgbh.org/invent_build/web_multimedia/accessible-digital-media-guide/disabilities-functional-limita

Each disability presents unique challenges to computer users.

BLIND USERS

To support screen reading software, developers can:

• use standard system tools to draw and erase all on-screen text and to display all cursors and pointers.
• use system standard on-screen controls whenever possible.
• define tools in toolbars, palettes, and menus as separate items, and avoid creating single graphics containing multiple objects. When tools and other objects are kept separate, the screen reader is better able to identify and name each tool for the user.
• embed descriptive text in graphic images in such a way as to make the text known to screen-reading software. This addresses the problems that can arise when text is rendered as a graphic image and cannot be read by software.
• assign logical names to controls, even if the name is not visible on the screen. Screen readers can access this information and use it to describe the type and function of the control on the screen.
• track the system cursor with the mouse, even if the cursor is invisible. This allows the screen-reading software to detect the mouse position when customized highlighting or focusing techniques are in use.
• use consistent and predictable screen and dialog layouts.
• avoid the use of "help" balloons that disappear whenever the hot spot, or focus of the mouse, changes. Locking the help balloon in place lets user move the cursor and continue to read the balloon.
• provide keyboard equivalents for all tools, menus, and dialog boxes.

Since screen readers can only read text (or give names to separately identifiable icons or tools), it is a good idea to:

• avoid assigning unlabeled hot spots to pictures for use as controls.
• avoid non-text menu items when possible or at least incorporate visible or invisible text cues to accompany these items. Screen readers can see text even if that text is written to the screen invisibly.
• avoid non-redundant graphic toolbars.

Finally, documentation and training materials are always more accessible when:

• documentation and on-line help can be understood independent of graphics. Text descriptions should stand on their own.
• synchronized audio descriptions are available to play alongside animated graphics or movies.

For People with Low Vision

"Low vision" refers to a range of vision problems including:

• poor acuity, meaning blurred or fogged vision.
• loss of all central vision; the ability to see only the outer ring of the visual field.
• tunnel vision; the ability to see only the center of the normal visual field.
• loss of vision in other parts of the visual field.
• other problems, including night blindness, reduced contrast and sensitivity to glare.

Computer users with low vision often depend on the ability to enlarge or otherwise enhance areas of on-screen information. Screen-enlargement software can be tremendously helpful.

To make on-screen information easier to see, developers can:

• increase the contrast between text and the background.
• place text over a solid-color background. A patterned background can make text harder to discern.
• create consistent layouts for all screens and dialogs within the program.
• provide access to tools via a menu bar.
• follow line-width guidelines when drawing lines on screen. Use the line-width information provided by operating system settings. This will ensure that the learning application will increase all lines proportionally should a user choose to enlarge the view.
• allow the user to zoom in on or magnify portions of the screen.

To make software more compatible with other applications that offer low-vision access features, developers can:

• use the system pointers whenever possible, as well as the system caret or insertion bar, if available.
• include a highlight or focus indicator when dragging the system cursor, even at those times when the cursor is invisible. This adjustment will help screen enlargement software using "pan and zoom" features to track the user's movements more accurately.
• add support for a "high contrast" setting.
• protect users from the need to monitor simultaneously two or more events occurring far apart from each other on the screen.

For People with Language or Cognitive Disabilities

Language and cognitive disabilities are very difficult for developers to address, partly because of the diversity represented in the category. The group includes individuals with:

• general processing difficulties such as mental retardation, brain injury and others.
• specific deficits such as lack of short-term memory, the inability to remember proper names and others.
• learning disabilities such as dyslexia, dyscalculia, dysgraphia, auditory perceptual disabilities, cognitive disorganization, and visual perceptual disabilities.
• language delays.

In addition, the degree of impairment within each of these categories can range broadly, from minimal to severe. In general, software designed to be as user-friendly as possible will improve accessibility for those with language or cognitive impairments.

To improve accessibility for people with language or cognitive disabilities, developers can:

• allow all message alerts to remain on screen until dismissed by the user.
• make language and instructions as simple and straightforward as possible, both on screen and in documentation.
• use simple and consistent screen layouts.

It is important to bear in mind that those with language and cognitive disabilities often have difficulty processing print. To increase accessibility for this population, developers should take steps to make their software compatible with screen-reading software

TOOLS FOR ACCESS
http://ncam.wgbh.org/invent_build/web_multimedia/accessible-digital-media-guide/tools-for-access

Assistive technology (AT) is an umbrella term used to describe any product or technology-based service that helps disabled people to live, learn, work and enjoy life. In the context of on-line education, assistive technology refers to hardware and software technologies that enable people with disabilities to use computers more effectively.

Screen Readers

Screen readers are software products designed for blind users, but they are also useful to users with learning disabilities. Screen readers locate information seen on the computer screen and vocalize it using text-to-speech software and, occasionally, hardware. Most screen readers work in close concert with the operating system, relying on the computer's built-in capabilities. Applications and software that conform to the standards of the operating system are more likely to be accessible. Applications and software that ignore the requirements of screen readers and the operating systems that support them may well prove unusable for some disabled people.

Screen Magnifiers

Screen magnifiers are software solutions for people with low vision. These products allow the user to enlarge the size of images and text displayed on screen. Screen magnifiers may also permit the user to change the default colors of the display.

Compatibility between screen magnifiers and software can be a problem for developers. Typical screen magnifiers track the cursor or the active region of the screen and will automatically enlarge that portion of the display. Applications that use a custom cursor design may cause the magnifier to enlarge the wrong portion of the screen. Developers can avoid this problem by relying on standard interface practices, particularly those that apply to cursor control and display.

Equivalent Access Versus Alternative Access

When considering accessibility of learning applications, it is important to understand the differences between two types of access: equivalent and alternative.

Equivalent access provides the disabled user with content identical to that used by the non-disabled user. For the disabled user, however, that content is presented in a different manner. Providing a course textbook in braille format, on audiotape, or in digital format are examples of equivalent accessibility.

Alternative access provides the disabled user with a learning activity that differs from the activity used by the non-disabled user. However, the alternative activity is designed to achieve the same learning objectives. For example, a mobility-impaired student might be given the option of conducting a science experiment in a virtual laboratory, where the levels of dexterity, strength, and physical access are different from those required in a physical laboratory.

There are numerous examples where software developed for alternative access has become the mainstream choice when its value to all learners was recognized. For example, the virtual microscope developed for disabled students by The Open University proved better able to achieve key learning objectives than its mainstream counterpart and so came to be used by all students.

Two months into 'H810: Accessible online learning: supporting disabled students' I find my antennae are picking up signs and symbols, practices and expectations related to access.

A bus that is full unable to take on the wheelchair user. A blind person on the tube.

Fig.2 Sign as you exit Tower Hill underground. I like the fact that neither the words 'disability' or 'access' are used.

A notice outside Tower Hill tube station and Vvideo clips on products, services and experiences that give some insight into whether or not a piece of assistive technology works or not.

This week (or last) I've been getting behind so jump back and forth between the two we were asked to try some specific tasks as if we were blind. Being the stubborn type I have pressed on with this, alone. Taking my glasses off is a shocking start as I find my face close to the screen. Wearing a blind fold is the next step. Also, as I videod test drivers doing, putting goggles made of plastic coffee cups with the bottoms cut out over my eyes to recreate tunnel vision.

The evidence of the last couple of months, let alone witnessing the Paralympics, shoes how far more diverse the community of people with disabilities is, compare to the rest of the population. Loss of vision is on a scale, as is hearing and mobility.

I guess this is what I am meant to conclude.

I have tried to test accessibility from the point of view of someone who is visually impaired before. I try again using narrator.

Why does it fail?

1) Am I personally adapt at tackling new technology? If so, how so? One way or another I will take to something, visually impaired or not, if I find it intuitive. More importantly I have to have a time and task critical goal. And if that isn't adequate motivation, what is? Motivation will overcome many hurdles.

2) My context, especially past experience of the tools being used. Here's a test.

This sentence is written entirely as a piece of touch tyoung, You can see for your self when and where I start to get lost.

To do this, I found myself looking up at the ceiling.

Actually, EXACTLY as I have seen a proficient blind user of JAWS do.

Think of a blind pianist like Stevie Wonder.

Why look at the screen that offers no clues ... no support, rather sit back and let your fingers do the talking and the seeing. There is a reason why learning the piano as a boy the teacher covered the keyboard - at least I had the music to sight read. Equally there is a reason why learning to touch type on day three or four or something I found myself sitting at a blanked out keyboard. Decades on I delight in the fact that six or more keys on the keyboard have been wiped clean. I just centre my hands and get on with it. A similar challenge has been drawing while not taking my eyes off the object (or person) I am drawing.

These are skills of dexterity, with or without sight.

The appropriate test for assistive technology has to be with someone with the impairment being tested for ... and ideally, as you would do in any research, with a group that are representative of the adapt as well as new comers.

Whilst personas will do, when we have credibly empathy with a potential user, when it comes to disabilities first hand experience is required - far better to engage them and understand it from their point of view than try to imagine what it is like. THIS is how the wrong decissions are taken. Instead of imagining what it might be like - get out and do first hand research with actual representative groups. This is far, far more revealing (as planners in advertising agencies will tell you).

Any of us could or will stumble the first time we are faced with a new tool or piece of software - I'd like to see any of us tested using a tool such as Delicious or ScoopIt and see how we get on, or trying to use a Microwriter, programme the washing machine or even turn on someone else's Microwave.

All experiences become familiar in time if we give them a go or get some useful tips. The same implies whether or not you have a disability or combination of disabilities or not.

To make sense of the plethora of accessibility tools, software and built-in 'assists' - and the equally enormous combinations and varieties of people who may benefit from using them I am having to get into my minds eye four people, or 'personas' who have quite different needs and imagine them, in context, wanting to and trying to use tools that ought to improve access for them. Some intriguingly are likely to suit all users if they offer a short cut or a different way into the information - I prefer a transcript over lectures. I like to use narrator in the car or when busy with some other task like painting the shed - the book is read to me as I can't do what I am doing and look at the screen at the same time. I call this the 'Montesori Effect' - how meeting a learning challenge for one community of learners you gain insights and create tools that benefit everyone.

As for any of us, when it comes to learning, context is important whether we have the space, time, kit and inclination. There is a big difference between giving something a go and having to use it with a set goal in mind. Anyone remember the first time they had to create something using PowerPoint, or Word come to think of it? Or writing a blog - let alone embedding images, video or audio.

Some of this reminds me of my first computer - an Amstrad. All green text and no mouse. My father got himself a Microwriter and mastered it. Bizarre. Confined to a wheelchair (badly broken leg from skiing) for some months in my early teens I ought to have been able to keep up with school work - but somehow a box of books didn't do it for me.

When I get stuck I can now turn to a son, daughter or my wife who may or may not be able to help. We also pick up the phone to 'The Lewes Computer Guy' for technical fixes. Had I a disability how likely is it that I can turn to someone with the very same set of challenges that I face for tips and advice? On some context a blind person will and can turn to a supportive community, but this might not be so easy if you are, or feel like, the only person with Dyslexia or Cerebral Palsy at your schoolor university.

| was introduced to Francesca Martinez performing on the stand-up comedy circuit by The OU as we are currently doing a module on accessibility to e-learning. Francesca has cerebral palsy - she doesn't let that get in her way. Her brand of sit-down stand-up comedy is infecticious, revealing and timely.

Catch the Saturday 6th September edition of 'The News Quiz'.

Knowing a number of young people with cerebral palsy I know to be more attentive - just because, to varying degrees, they may struggle to get their words out, does not mean they don't have something to say. The other lesson is to be open, to be frank - you have to ask openly with them what they can or cannot do, or would like to do or overcome. Even if I had some professional knowledge of a range of disabilities it will still be necessary to discuss with the individual where they stand - something that may shift week on week, in their favour after operations or against if the disease is degenerative. The difference here compared to the general population is accommodation rather than indulgence - it puts into sharp perspective the young person or parent of a young person who pushes and stretches the bounds of indulgence forgetting that life of necessity includes compromise, and give as well as take.

The barriers to this are time, numbers and comprehension - as well as any inherent risks in relation to the learning environment. As a 'lead educator' - a teacher or coach, you have to respond to the current situation as it unfolds. It helps to have some sense of who the people are, to know where their individual strengths and weaknesses lie.

If time is one issue, then make more time as a result if preparation, even arrange to meet some students earlier if this is possible so that you can fit in a quick word with them.

If numbers are an issue then be slick with registarations, insist on people turning up in good time and if necessary stagger the start - in some situations an assistant or parent should help out, to guide one person or to pick up on some tasks (the issue here is where a young person is very concsciously trying to be more independent). If comprehension and communication are an issue, then do the above - give it more time and find ways to cope with the numbers, then be open and accommodating, use common sense to find or be told the best way to communicate - ideally therefore have some kind of hand-over where you can be introduced to the best way forward. Returning to Francesca Martinez - she held her own and deserved to be on the show - she is funy and spontaneous, blunt and entertaining. She can only be judged on these qualities in this context - access means removing or alleviating barriers to get onto such a stage, it does not mean changing the height if the bar, just as an undergraduate with a disabilitiy starting in higher education having got to this level has to be judged by how they perform, assessed or judged at the same level as other undergraduates. In relation to e-learning this means creating access where there is a barrier, while maintaining standards when it comes to assessment and awarding qualifications.

While studying for a Masters in Open and Distance Learning (MAODE) I love to have one or more books on the go to read from cover to cover.

Courtesy of the eBook format, as I read I highlight, bookmark, make notes and share excerpts on Twitter @JJ27VV.

The OU courses don't do whole books (with one exception).

Sections highlighted by other readers are indicated too making the reading process less of the private, isolated affair it was in the past. John Seely Brown spoke at The OU too, so find his lecture here.

When it comes to e-learning there are a handful of must-read books, such as his one.

What have you come across that you would recommend?

We are this nation, this community as a consequence of crisis set on an island (or two or more).

Mess in a bubble. Historically change has been elastic and ultimately plural and accommodating. In relation to my current module H810, we are currently looking at 'reasonable adjustements' that institutions and employers should make for people with disabilities.

There's just so much tweaking you can do.

I'd like to see a greenfield campus, along the lines of the Olympic Village reconfigured for the Paralympics. Take a venue for wheelchair basketball and turn it into a lecture hall - only then can you reasonably cater for students, personal assistants and note takers and support for the lecturer to provide alternative versions of their slides and notes. They had better be good. Release it as a TED lecture too.

My criticism of the schooling I had was that, like a sausage machine its modus operandi was to cut me into a shape that they required during schooling and expected as an outcome - with parents in cahoots. There was never room for anything but the mildest of disabilities and even here asthmatic, hearing and learning difficulties were, at best tolerated, at worst a label that staff and pupils used to set this person apart as an 'alien'.

There is a need to accommodate differences, the uniqueness of each of us and how to develop the best from each person without dogma or coralling everyone down the same path.

Across education institutions need to see parents and students as customers or clients, who directly or indirectly are paying for the good or poor service they recieve in equal measure. Far more effort by people needs to be put into listening and ubderstanding in an informed and educated way.
