Self and Peer Grading on Student Learning – Dr. Daphne Koller

Fig. 1. Slide from Dr Daphne Koller‘s recent TED lecture (Sadler and Goodie, 2006)

I just watched Daphne Koller’s TED lecture on the necessity and value of students marking their own work. (for the fifth time!)

Whilst there will always be one or two who cheat or those who are plagiarists, the results from ‘Big Data’ on open learning courses indicate that it can be a highly effective way forward on many counts.

  1. it permits grading where you have 1,000 or 10,000 students that would otherwise be very expensive, cumbersome and time consuming
  2. as a student you learn from the assessment process – of your work and that of others
  3. student assessment of other’s work is close to that of tutors though it tends to be a little more harsh
  4. student assessment of their own work is even closer to the grade their tutor would have given with exceptions at opposite ends of the scale – poor students give themselves too high a grade and top students mark themselves down.

Conclusions

  •  it works
  •  it’s necessary if learning reach is to be vastly extended
  • isn’t human nature a wonderful thing?! It makes me smile. There’s an expression, is it Cockney? Where one person says to another ‘what are you like?’

Fascinating.

‘What are we like?’ indeed!

The spoken word is crucial to understanding.

The spoken word is crucial to understanding.

‘I don’t know what I mean until I have heard myself say it, Said Irish author and satirist Jonathan Swift

Conversation plays a crucial element of socialised learning.

Courtesy of a Google Hangout we can record and share such interactions such as in this conversation on and around ‘personal knowledge management’. Here we can both see and hear why the spoken word is so important.

Trying to understand the historical nature of this, how and when the written word, or other symbols began to impinge on the spoken word requires investigating the earliest forms of the written word and trying to extrapolate the evidence of this important oral tradition, the impact it had on society and the transition that occurred, after all, it is this transition that fascinates us today as we embrace the Internet.

Humans have been around for between 100,000 and 200,000 years. (Encyclopedia Britannica).

There are pigments and cave painting have been found that are 350,000 years old. (Barham 2013), while here are cave paintings as old as 40,000 years (New Scientist).

Stone Age man’s first forays into art were taking place at the same time as the development of more efficient hunting equipment, including tools that combined both wooden handles and stone implements. (BBC, 2012). Art and technology therefore go hand in hand – implying that the new tools of the Internet will spawn flourishing new wave of creation, which I believe to be the case. This era will be as remarkable for the development of the Web into every aspect of our lives as it will be for a epoch identifying renaissance – a new way of seeing things.

We’ve been seeking ways to communicate beyond the transience of the spoken word for millennia.

McLuhan takes us to the spoken word memorised in song and poetry (Lord, 1960 p. 3) while a contemporary writer, Viktor Mayer-Schonbeger, (2009. p. 25) also talks about how rhyme and meter facilitated remembering. McLuhan draws on 1950s scholarship on Shakespeare and asks us to understand that Lear tells us of shifting political views in the Tudor era as a consequence of a burgeoning mechanical age and the growth of print publishing. (Cruttwell, 1955)  McLuhan suggests that the left-wing Machiavellianism in Lear who submits to ‘a darker purpose’ to subdivide of his kingdom is indicative of how society say itself developing at a time of change in Tudor times. Was Shakespeare clairvoyant? Did audiences hang on his words as other generations harken the thoughts of  H G Wells and Karl Popper, perhaps as we do with the likes Alan de Bouton and Malcolm Gladwell?

‘The Word as spoken or sung, together with a visual image of the speaker or singer, has meanwhile been regaining its hold through electrical engineering’.xii. Wrote Prof. Harry Levin to the preface of The Singer of Tales.

Was a revolution caused by the development of and use of the phonetic alphabet?

Or from the use of barter to the use of money?

Was the ‘technological revolution’ of which McLuhan speaks quoting Peter Drucker, the product of a change in society or did society change because of the ‘technological revolution’? (Drucker, 1961) Was it ever a revolution?

We need to be careful in our choice of words – a development in the way cave paintings are done may be called a ‘revolution’ but something that took thousands of years to come about is hardly that.

Similarly periods in modern history are rarely so revolutionary when we stand back and plot the diffusion of an innovation (Rogers, 2005) which Rogers defines as “an idea, practice, or object that is perceived as new by an individual or other unit of adoption. (Rogers, 2005. p. 12). To my thinking, ‘diffusion’ appears to be a better way to consider what has been occurring over the last few decades in relation to ‘technology enhanced communications’, the Internet and the World Wide Web. But to my ears ‘diffusion’ sounds like ‘transfusion’ or ‘infusion’ – something that melts into the fabric of our existence. If we think of society as a complex tapestry of interwoven systems then the Web is a phenomenon that has been absorbed into what already exists – this sounds like an evolving process rather than any revolution. In context of course, this is a ‘revolution’ that is only apparent as such by those who have lived through the change; just as baby boomers grew up with television and may not relate to the perspective that McLuhan gives it and those born in the last decade or so take mobile phones and the Internet as part of their reality with no sense of what came before.

Clay tablets, papyri and the printing press evolved. We are often surprised at just how long the transition took.

To use socio-political terms that evoke conflict and battle is a mistake. Neither the printing press, nor radio, nor television, nor the Internet have been ‘revolutions’ with events to spark them akin to the storming of the Bastille in 1789 or the February Revolution in Russia in 1917 – they have been evolutionary.

Are we living in ‘two forms of contrasted forms of society and experience’ as Marshall McLuhan suggested occurred in the Elizabethan Age between the typographical and the mechanical ages? Then occurred between in the 1960s  between the industrial and electrical ages? ‘Rendering individualism obsolete’. (McLuhan 1962. p. 1)

Individualism requires definition. Did it come with the universal adult suffrage?

Was it bestowed on people, or is it a personality trait? Are we not all at some point alone and individual, as well as part of a family, community or wider culture and society? We are surely both a part and part of humanity at the same time?

Edward Hall (1959), tells us that ‘all man–made material things can be treated asextensions of what man once did with his body or some specialized part of his body. The Internet can therefore become and is already an extension of our minds. A diarist since 1975 I have blogged since 1999 and have put portions of the handwritten diary online too – tagging it so that it can be searched by theme and incident, often charting my progress through subjects as diverse as English Literature, British History, Geography, Anthropology and Remote Sensing from Space, Sports Coaching (swimming, water-polo and sailing). This aide memoire has a new level of sophistication when I can refer to and even read text books I had to use in my teens. It is an extension of my mind as the moments I write about are from my personal experience – there is already a record in my mind.

What is the Internet doing to society? What role has it played in the ‘Arab Spring’? McLuhan considered the work of Karl Popper on the detribalization of Greece in the ancient world). Was an oral tradition manifesting itself in the written word the cause of conflict between Athens and Sparta? McLuhan talks of ‘the Open Society’ in the era of television the way we do with the Internet. We talked about the ‘Global Village’ in the 1980s and 1990s so what do we have now? Karl Popper developed an idea that from closed societies  (1965) through speech, drum and ear we came to  our open societies functioning by way of abstract relations such as exchange or co–operation. – to the entire human family into a single global tribe.

The Global kitchen counter (where I work, on my feet, all day), or the global ‘desk’ if we are sharing from a workspace …

or even the ‘global pocket’ when I think of how an Open University Business School MBA student described doing an MBA using an iPad and a smartphone as a ‘university in my pocket’. You join a webinar or Google Hangout and find yourself in another person’s kitchen, study or even their bed. (Enjoying one such hangout with a group of postgraduate students of the Open University’s Masters in Open and Distance Education – MAODE – we agreed for one session to treat it as a pyjama party. Odd, but representative of the age we live in – fellow students were joining from the UK, Germany, Thailand and the United Arab Emirates). I have been part of such a group with people in New Zealand and California – with people half asleep because it is either very late at night, or very early in the morning.

McLuhan  (1965. p. 7) concludes that the ‘open society’ was affected by phonetic literacy …

and is now threatened with eradication by electric media. Writing fifty years ago is it not time we re-appraised McLuhan’s work and put it in context. We need to take his thesis of its pedestal. Whilst it drew attention at the time it is wrong to suggest that what he had to say in relation to the mass media (radio and TV) if even correct then, others insight in the era of the Internet.  This process of creating an open society has a far broader brief and with a far finer grain today – , the TV of the sitting room viewed by a family, is now a smart device in your pocket that goes with you to the lavatory, to bed, as you commute between work and in coffee and lunch breaks. It will soon be wearable, not only always on, but always attached as goggles, glasses, ear-piece, strap or badge.

If ‘technology extended senses’ McLuhan, 1965. p.8 then the technology we hold, pocket and wear today, are a prosthesis to our senses and to the manner in which the product of these senses is stored, labelled, interpreted, shared, re-lived, and reflected upon.

If Mercators maps and cartography altered 16th century mentality what do Google Maps and Street View do for ours?

Did  the world of sound gives way to the world of vision? (McLuhan, 1965 p.19). What could we learn from anthropologists who looked at non–literate natives with literate natives, the non–literate man with the Western man.

Synchronous conversation online is bringing us back to the power and value of the spoken word – even if it can be recorded, visualised with video and transcripted to form text. The power, nuance and understanding from an interchange is clear.

The Gutenberg Galaxy – first thoughts, from the first pages

20130209-180616.jpg

Fig. 1. The Gutenberg Galaxy – Marshall McLuhan (courtesy of Amazon and a US bookseller)

Like visiting a library, having a book as an object in my hand, a singular artifact rather than its substance digitised, feels like a visit to a National Trust property. There’s meaning in it, but that way it’s packaged is all a bit ‘historic’.

Mosaic – kaleidoscope – environment – constellation

These are some of the ways Marshall McLuhan may have written about the changing society he was commenting on in the early 1960s with reference to previous shifts from an oral to a written tradition, with a phonetic alphabetic to the printing press.

We like to visualise the complex – to simplify it.

No less so than in what we perceive as a new era – that of the Internet and ever deeper, faster, more complex and fluid, even intelligent ways to communicate, share and think.

In the prologue p.1 we are told that papyrus created the social environment – how?

Immediately we know that Marshall McLuhan will be talking about an elite as if they represent everyone. authors are constantly guilty of this today, discounting those who lack digital literacies as if all that matters in the world is what these people are doing – as if it is above, beyond and distinct from everyone else. Or should we just tackle this interconnected community and ignore those who are not and may never be part of it – those thousands of millions who do not have Internet access 24/7, just as when dealing with previous eras the illiterate are ignored because they voice could not be captured and disseminated?

Society existed before script – so few could write and read would make the impact of papyri irrelevant to all but the smallest of minorities, the elite who could write and read, own and store such things.

The stirrup and the wheel – is offered as a period of transition.

We are to think of this transition as a revolution, just as the development of print from the time of Gutenberg is described as a revolution – not matter how many centuries it took to evolve, and the development of TV from Marshall McLuhan’s particular is another, as the innovation shines such a bright light that it becomes impossible to see anything else. Far from television replacing the written word it has expanded at a time of vastly increased literacy rates and has been complemented to a burgeoning publishing of cheap paperbacks, journals and magazines.

‘Technological environments are not merely passive containers of people but are active processes that reshape people and other technologies like’. (McLuhan, 1962. p.0).

As an aphorism this may apply – by ‘environment’ Marshall McLuhan is once again searching for words, in conversation in the 1960s I would imagine him saying ‘technological mosaic’ and then correcting himself and saying ‘technological constellation’. Several decades on and we may be better able to comprehend ‘technological system’ in the context of Cultural Historical Activity Theory (Engestrorm, 2006) or ‘technological ecosystem or ecology’ (Bateson, 1972., Lukin, 2008)

Applications of metaphorical notions of ecology, culture and politics can help us better understand and deal with these complexities. (Conole. 2011. p. 410)

Then McLuhan tells us that print created the public – by inference did those who made up the majority in society not exist as a ‘public’ until then?

There is a sense as he later draws on the work of anthropologist X to infer that those with only an oral form of communication are part of an amorphous mass, that literacy empowered a new, though initially quite small group, to gain some kind of status through print.

‘Electric circuitry does not support the extension of the visual modalities in any degree approaching the visual power of the printed word’. Says McLuhan who sees television in the 1950s and the 1960s as something as ephemeral and passing as radio.

Without the research then available that tells us that watching TV is a passive activity that has little impact on the short term memory and next to none on the long-term, McLuhan is saying that electrical forms of the visual have less substance than the printed form of the visual. It isn’t however the means of distribution that is the cause of this, the thesis of all the Marshall McLuhan is remembered for, but the way we behave in front of these technologies – simply put, we sit forward and make an effort to read from a book, even to interpret pictures, but with TV we sit back and let it wash over us. ( Myrtek at al, 1996) Umberto Eco (1989) explains how the read gives meaning to the ‘open’ book, a far more rewarding experienced that the reading of a ‘closed’ text – the same applies to all media -we the viewer, reader, player or participant provide the meaning; the interpretation is our own.

With content from the Internet we can do either or both, or one or the other and the kinds of interaction and engagement that are far more complex and today far more like direct, face to face interaction as we do deals, discuss and debate in live groups and play massive online games.

How more deeply embedded is a visual memory if you crafted the drawing or painting that is the catalyst for its recall.

Fig.1. Hockney on iPad. Now here’s a lifelog to treasure. How does the master i-paint?

If a moment is to be captured, maybe David Hockney has the answer with a iBrush painting on an iPad. This is closer to the truth of a moment, seen through the artist’s being, their psychological and physiological approach to what they both see and perceive in front of them.

When we do we form a real memory of the actions required to undertake a task. We build on our initial attempts. The memory to ski, to dance, to swim, to skip, to ride a bicycle, to write, to draw, to pay a musical instrument – these cannot be caught by a complex collection of digital recording devices. Perhaps if the player wore a total bodysuit as actors do to play CGI generated character then we’d have a record of the memory of this experience. It wouldn’t a digital memory make – just a record.

The Semantic Web aims to standardize transmission and translation of information, is an important effort in this area. (Bell and Gemmel, 2009 p. 220 )

Is it really necessary, possible or desirable to take the moronic  qualities of sports coverage and impose it on a person going about their every day and far less eventful day. This is the premise for a comedy sketch. (Bell and Gemmel, 2009. p. 224)

Fig. 2.  How we learn. Conceptualised in SimpleMinds while taking the Open University Masters in Open and Distance Education.

All praise to the blogger Mark Stewart but does such a record need to be entertaining to gain validity and so a place in Digital Lives  at the British Library. (Bell and Gemmel, 2009. p. 225)

Though remembering and talking through a difficult time can also offer its solution. However, these is a difference between hoarding the memory or keeping it to yourself, and letting it go. The wrong memories permanently on recall will be multiple albatrosses.

Take WW1 veterans, or any war veterans, some want to tell, some went to bury. Why should people in the future feel obliged to record it all, to have more than enough to bring it back?

As written language is such a recent phenomenon it is perhaps not the best or even the most natural way to remember.

Going back we had the drawn image and the spoken word, but never the absolute of a panoramic or 360 digital picture, but rather moment filtered through the mind and expressed at the fingertips as a painting or drawing.

Fig. 3. Web 1.0 invigorated by Web 2.0 into a water-cycle of, appropriately, clouds.

Weather systems and water courses, urban run–off and transpiration.

Here the flotsam and jetsam of web content, the good, the bad, the ugly and ridiculous, the massive, the moving, the invaluable as well as the ephemera, is agitated, mixed–up and circulated, viewed, pinched, reborn, mashed up, bashed up or left to atrophy – but it is in the mix and open for business. Find it and the thought, or image, or sound bite,  the message, the idea is yours to dwell upon and utilise. It is education, revelation and knowledge of a new order. Expect more of the same and the unexpected.

You read about people looking at ways to capture everything – to automatically lifelog the lot. They constantly look for new ways to gather and store this data. What’s the point? Because they can? Who are they? Is it a life worth remembering? And do we need it all?!

Far better to understand who and what we are and use the technology either to ameliorate our shortcomings, aid those with memory related challenges and tailored to specific needs captured moments of worth.

There’s ample literature on the subject. I’m not overly excited about revolutionary change. It is as valuable, possibly more so, to forget, rather than to remember – and when you do remember to have those memories coloured by perspective and context.

My interest is in supporting people with dementia and cognitive difficulties – perhaps those recovering from a stroke for whom a guided path of stimulation into their past could help ‘awaken’ damaged memories. If lives are to be stored, then perhaps grab moments as a surgeon operates for training purposes, recreate a 3:1 tutorial system with AI managed avatars so that such learning practices can be offered to hundreds of thousands rather than just the privilege, elite or lucky few. Use the device on cars, not people, to monitor and manage poor driving – indeed wear one of these devices and see your insurance premiums plummet.

What does it mean to support human memory, rather than capturing everything.

Five Rs

  1. Recollect
  2. Reminisce
  3. Retrieve
  4. Reflect
  5. Remember

Despite the device SenseCam stimulate memories are as quickly forgotten as any other.
Whittacker 2010 – Family archives of photos are rarely accessed

Of less value than the considerable effort to produce these archives justifies.

  • Can’t capture everything
  • Need to prioritise – selectivity (as SwimTag and swim data)
  • Visual
  • Memory taxonomies
  • Quick and easy to use better than accuracy – good enough
  • Cues not capture – the data cues memories that are different to the image captured.
  • Memory is complex

Play to the strengths of human memory, help overcome weaknesses.

Incorporating the psychology of memory into the design of novel mnemonic devices opens up exciting possibilities of ways to augment and support human endeavours.

Problems

 

  • Internet Access
  • Accuracy (outside 10m)
  • Loss of signal/bandwidth
  • Cost of equipment
  • Battery life
  • Sunlight (or artificial light indoors)
  • Durability (water, physical damage)
  • Compromised learning to cope with the limitations of the device

Opportunities

 

  • Appeal to students of using their devices (Lickin and Stanton Fraser, 2011)
  • Personalised learning through kit and software tools

  • Encourages problem solving
  • Collaboration through synchronised interaction
  • Eyetap technology in Google Glass
  • Exploitation of ‘dead time’ (Petit and Kukulska-Hulme, 2007)

 

‘Most noteworthy to teachers was how the technology-enhanced curriculum enacted students’ identities as problem solvers and knowledge builders rather than as compliant consumers of
information…”.’ (Squire, 2010)

 

CONCLUSION

 

What is clear is that we currently have the opportunity to provide immersive, compelling and engaging learning experiences through augmented reality, which are situated in real world contexts and can provide a unique and personal way of making sense of the world around us. FitzGerald et al (2012)

Does the organisation where you work have an accessibility (or similar) policy?

I’m going to consider this from three perspectives:

  1. a substantial learning provider that is migrating content to the web wholesale (no policy);
  2. an e-learning agency that produces modules for learning and design managers (the policy is the policy of each different client)
  3. at the Amateur Swimming Association who have a meaningful relationship with disabled swimmers (a policy toward athletes may not be as supportive and accessible when it comes to their own teachers and coaches).

In due course I’ll consider accessibility in relation to content and resources provided by the Open University whom one would expect to be leader in this field – indeed I believe they are and it is apparent as soon as you look at a page of OU e-learning content compared to the kinds of materials  typically produced for corporate clients. Having worked for or in such organisations I can identify differences and suggest reasons for the decisions taken.

If your organisation does not have a policy, why do you think this might be?

I would like to consider this from the point of view of three learning providers –  a substantial institution akin to the OU, a specialist niche trade association and from the perspective of an agency that creates e-learning.

Does your organisation have someone in a senior position whose job it could be to lead accessibility-related policies and initiatives?

The person responsible ought to be senior, ought to carry influence, have personal knowledge or training in relation to access and accessibility and demonstrate the leadership qualities that come from taking on something new and seeing it through.

Are senior management aware of accessibility issues and simply choosing to ignore them?

People are in love with the cutting edge of e-learning – desiring an advanced look and feel and the smart technology behind tracking personal development, e-assessments and accreditation, rather than standing back and favouring instead something cleaner, simpler, perhaps less fashionable, but more accessible – and potentially easier to scale, adjust and for assistive technology – to read. Effectiveness, cost effectiveness and accessible ought to be priorities rather than gamification, virtual worlds and all encompassing solutions where a smorgasbord of choices and decisions is a better reality.

If there are laws in relation to discrimination that have teeth then no person or institution has yet been taken to court.

Has a decision been made that policies are not the right tool to use to try to change practice?

Agencies will do as asked – issues of accessibility might be raised at the briefing stage and the client will say then to what degree accessibility matters and share how accessibility issues have been addressed in the past in their organisation- usually piecemeal and after the event rather than building accessibility in from the start. No one has consider an approach, whether a policy or a design and technical response. The difficulty faced by an agency pitching in a competitive environment for work is that the market too often favours used of the latest gizmos and the most compelling, potentially award winning design. The policy should be for effectiveness and value for money with a close look at cost effectiveness based on old as well as new media.

If so, how is your organisation communicating to staff any desire or intention relating to accessibility?

Will any individual or group of students be significantly disadvantaged if they are required by their programme or institution to use the proposed system? (Seale 2006:128)

This needs to be at the top of the agenda.

Just like a change in management practice or take over of or by a business communication with people should be thorough, timely and authentic. If attitudes have to be changed, developed or refreshed the effort will be all the greater. This requires commitment and resources from the top and engagement of people familiar with such exercises.

How might you improve on accessibility-related policies that exist in your organisation?

1) Find a champion and a leader – if necessary two different people.
2) Get disabled students involved in deciding and advising on policy based on their experiences
3) Know the legal position and comply – tie in with ISO and Plain English policy and compliance (best practice).
4) Organisations have to mean it and be professional about it
5) TEAM WORK
6) Purchasing decisions
7) Benchmark accessibility

CHAMPION

1) There has to be someone to champion the cause, needs, benefits and legal requirements of accessibility. This person needs leadership qualities – informed, persuasive, by example, with authority, credibility and presence. Seale (2006:128) suggests that supportive managers with a positive attitude are need, people with previous experience of supporting students with disabilities. Seale (2006:128)
Accessibility implementation needs to be actively managed (Lamshed et al. 2003) Seale (2006:128)

  • ensuring that the accessibility of e-learning material and resources is monitored and audited (see Seale (2006 chapter 7)
  • ensuring that there is ‘joined up’ thinking between the different specialist and mainstream learning support services within an institution (see Seale 2006 chapter 8)
  • ensuring that staff development opportunities are strategically targeted to raise awareness and that staff are able to respond to accessibility requirements (see Seale 2006 chapter 9)
  • developing and implementing procurement procedures to ensure accessibility of future technology purchases;developing and implementing institutional accessibility policies.

USER GROUP ENGAGEMENT

2) Talk to and engage with end users – be proactive, learning to accommodate and work with the broadest church or representative disabled students.

From US. (Oregon) Accommodations in postsecondary education are governed by Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990 (ADA).
Students with a documented disability have a right to receive reasonable accommodations. Additionally students have responsibilities which include:

  1. Providing the DAS office with appropriate documentation
  2. Responding to requests for information
  3. Scheduling and completing a required DAS orientation
  4. Making requests for accommodations according to the DAS Timeline for Service Requests before and during each term of attendance
  5. Following the policies and procedures which are available in the DAS Student Handbook

KNOW THE LEGAL POSITION

3) The legalese must be understood – ignorance of the law is no excuse – ideally a legal advisor will inform the CEO and Board, or trustees should seek advice and exirt pressure – that or responding to demands from society and individual campaigns. People need to believe that an organisation could be taken to court for failure to comply to accessibility legislation. Compliance. Level Double-A Conformance to Web Content Accessibility Guidelines 1.0 http://www.w3.org/WAI/WCAG1AA-Conformance

Comply with the Disability Discrimination Act 1995 Part Four (as amended by Special Educational Needs Disability Act 2001) and the Disability Discrimination Act 2005. All of the Priority 1, 2 and 3 accessibility checkpoints across websites, as established in the World Wide Web Consortium’s (W3C) Web Accessibility Initiative (WAI). The WAI promotes a high degree of usability and accessibility for people with disabilities.

It is possible that some of our older pages (those not within our new visual identity) might not currently conform to these standards. However, we are actively engaging with our website team to ensure that all future web pages are compliant with W3C guidelines for accessibility.

Like compliance to IS0 9000 and 9001

CLOUT

4). Purchasing decisions need to take accessibility into consideration – so someone with control on budgets needs to have a say. All new purchases of learning management systems, courseware and networked equipment is accessible (Rowland 2000; McCarthy 2001). He who pays the piper, plays the tune.

MISSION STATEMENT

5). Some organisations could or do put issues into their mission statement or reflect specific brand values – just as companies have ‘gone green’, so too they ought to be looking at both accessibility and equality as part of their corporate and social responsibility mix.  Anderson (2004) argues that practice will only change if the policy is actively implemented:Developing campus Web accessibility policies, guidelines or standards is often thought of as a way to meet legal obligation, however, implementing Web accessibility policies can be a means for creating a campus e-culture of inclusion. While developing a policy has numerous challenges – implementing, supporting and updating a Web accessibility policy is where the rubber hits the road and separates those who succeed in Web accessibility efforts and those who have a policy. (Anderson 2004)

  • embedding accessibility across all institutional activities and systems, from procurement to student support services;
  • addressing whether and how the development of an institutional accessibility policy will encourage such embedment;
  • identifying a team of key stakeholders, across the whole institution (and not just specialist disability services) who are willing and able to work towards embedment.

This may or may not be a ‘tall order’ (Wilson et al. 2002: 20), but without leadership from managers the task will not get any ‘smaller’.

TEAM WORK

6). It is a grave error to make access the responsibility of one person – and the cliche is to give the role of ‘Disability Officer’ to the one person in a wheelchair. Rather to be effective an ‘action team’ needs to be created so that from across the organisations there are partnerships with a range of representative stakeholders. it must be both a collaborative and a team effort.

Byrne (2004) suggests that in setting up a ‘Web Accessibility Policy and Planning Group’ the following stakeholders (among others) should be included: management, student representatives, disabled students, administrators, web designers, lecturers and learning support staff.

  • involve all stakeholders, including top-level support (Burgstahler 2002a; Smith and Lyman 2005);
  • organize an accessibility committee (Smith and Lymann 2005; Hriko 2003; Byrne 2004);
  • provide training and technical support (Smith and Lyman 2005; Burgstahler 2002a; Brewer and Horton 2002);
  • promote institutional awareness (Burgstahler 2002a; Brewer and Horton 2002);
  • evaluate progress towards accessibility (Smith and Lyman 2005; Burgstahler 2002a; Brewer and Horton 2002).

MEAN IT

7). Organisations have to mean it – not pay lip service, but set SMART goals, adhere to plans, be open with failings and strive to make things better. Whilst mission statements and guidelines are a move in the right direction, they will not necessarily ensure or mandate that practice changes. In order to ensure accessibility, policies need to be specific, detailed and directive.

i.e. SMART goals

Specific
Measurable
Attainable
Relevant
Time Bound

Advice from a number of accessibility advocates would suggest that accessibility policies need to:

  • define the scope of the policy (Johnson et al. 2003; Brewer 2002);
  • delineate a specific and official technical standard (Johnson et al. 2003; Bohman 2003d; Brewer 2002; Smith and Lyman 2005);
  • indicate whether compliance is required (Bohman 2003d);
  • indicate a timeline or deadline for compliance (Bohman 2003d; Brewer 2002);
  • define a system for evaluating or monitoring compliance (Bohman 2003d; Brewer 2002; Smith and Lyman 2005);

[page 132]

  • indicate any consequences for failure to comply with policy (Bohman 2003d).

Seale (2006:131)

BENCHMARK

8). Benchmark accessibility annually and raise the bar each year too, with comparisons tolike institutions – are we doing better or worse – and particular with those those organisations the ‘action team’ admire for what they are doing or have achieved. A useful exercise would be to look at the history of adoption of access in the physical world, the debates, legislation and practices. Change to be done appropriately and to be permanent takes time.

Develop the view that making accommodations for students with disabilities forms part of the institution’s engagement with learning technologies, can provide efficiencies and improve business agility and performance.

REVIEW – Visitors using the centre are taken through a structured questionnaire that enables them to review their learning practices and compare their level of performance against evolving good practice.

COMPARE – Three key performance indicators above.

ACT – Once you have identified where you can improve , the centre contains over 200 resources to help you take action in your business.

TOWARDS MATURITY (2012)

If none exist, what might you include in any new accessibility-related policy within an organisation?

It would be an interesting activity to hold a meeting and hand out books pertaining to contain text that are blank, to be handed a laptop on which all the keys have been glued down, a radio that scrambles the audio.

Design with Assistive Technology (AT) in mind. ‘As technology evolves, Assistive Technology (AT) often becomes outdated, leaving developers scrambling to produce new forms of AT to “catch-up” to IT. In the meantime, individuals relying on AT are left with obsolete equipment and consequently, reduced access to information and services. Although AT does catch up, inevitably, the accessibility cycle repeats itself as technology is too often developed with little or no thought to accessibility’. KATSEVA (2004)

‘Typically, technology is designed for functionality from the outset and made accessible only after-the-fact, either with AT or with retrofitting. This process excludes those for whom access to information and services is already difficult, as well as being terribly inefficient and costly. This process is akin to building a house without the electrical infrastructure, only to have each room wired individually, as new appliances are purchased’. KATSEVA (2004)

Does your organisation have other policies that should refer to accessibility?

If so, do they refer to it? If not, in what ways should they refer to it? Kelly et al. (2004) note that IT Service departments usually aim to provide a secure, robust managed environment, which may conflict with the flexibility many end users would like. (Seale 2006:128) The same is likely to occur with the strict adherence to web accessibility policies. There will need to be a compromise. The IT department, as they are used to managing and even policing IT should perhaps become the guardians of accessibility policy too as it would impact on design and programmining choices.

Who are the key people who have a role in managing accessibility in your organisation?

What helps or hinders them working together on accessibility-related issues?

Leading an institution’s response increases the visibility of accessibility as an issue, makes it easier to dedicate the necessary resources to the issue and makes the monitoring of compliance more of a probability (WebAim n.d.b).

At Cranfield University, we try to ensure that our services, products and facilities are available to all – irrespective of any disability. This applies to our website, too. Our website has been built following expert disability advice. (http://www.cranfield.ac.uk/ prospectus/ note.cfm) SEE APPENDIX 6

Oregon State University provides on its website a set of general web accessibility guidelines:

The universal access to information is a part of the University’s ongoing commitment to establishing a barrier free learning community at Oregon State. These guidelines have been established as a part of this commitment, and to meet the ethical and legal obligations that we have under The Americans with Disabilities Act, The Telecommunications Act of 1996, and The Rehabilitation Act of 1973, as amended.

The Oregon State policy has been replaced by Disability Access Services Mission and Goals, http://ds.oregonstate.edu/ about/mission.php (last accessed 24 May 2012).

Integration not segregation

Given that many advocates argue against ‘add-on’ specialist services that segregate people and issues from the mainstream, there would seem to be merit in considering whether accessibility should be integrated into existing policies or whether existing policies can be applied to e-learning accessibility.

Using this argument, perhaps accessibility should be embedded into a range of policies and strategies including: e-learning strategies; teaching and learning strategies; non-discrimination policies; inclusion policies; widening participation policies and learning resources policies.
