A note here on the learning process and the online learning experience

Visible to anyone in the world
Edited by Jonathan Vernon, Saturday, 12 Jan 2013, 13:33

I'm still thinking this through so share it here - actually I'm finding support from fellow MAODErs who did H810 in 2010 and 2011 as our tutor group is so exceptionally quiet sad.

I've also been following other tutor groups and can't wonder why some of these groups weren't merged some time ago for the benefit of all - putting us in silos isn't working, which shows the lack of flexibility in this 'system'. One caveat, I know from past experience that there will always be some who care to be more active online than others - I recall being part of one tutor group where some six of the 12 were highly engaged online on other platforms anyway so that anything any of us posted was immediately picked up by the others.

Just a note here on the learning process and the online learning experience

Having the opportunity to share thoughts, get it wrong, be corrected, think through the complexities and come to your own conclusions is surely a vital part of learning online? Indeed, using tools such as this, the blog ... and the wiki are what differentiates online learning in 2012/2013 compared to distance learning of a decade ago or more when you got a box of books and DVDs through the post with some instructions on what to read and when to hand in an essay. (Decades ago I've had a file insert sent in the post each month, or an audio cassette - self-directed learning requiring a huge amount of will power).

So, for anyone who wishes to consider why some issue are more important than others, and to clarify the difference between an issue, a model or a concept, here are my thoughts on what to take from Chapters 11,12 and 13.

Having cut out the duplications and overlaps and categorised the 'issues' I can only find ten. I would have thought one way or another THREE can be selected for the EMA from these. The next step is to rank them. I've loaded these into a table and cross-referenced each. I could write 500 words on each - the problems is to write 1800 or so on each of three.

From Chapter 11

1 Game-like play between institutions
2 Investment
3  The role of rules  (legalese and guidelines) - informal and formal


From Chapter 12

4  Role of tools
5 Significance  or role of the subject (student/lecturer)
6 The importance of and scoping of the objective as means to an outcome.
X Rules (see above)
X Community (see below)
7 Contradictions , conflicts of problems with the actions requires between components of  a recognised activity system
8  The role of the novice  to learn, participate and develop expertise.
9 What the history of  such efforts says about  what should be done next and what can be achieved in  the future.


From Chapter 13

10  The community  as a ‘community of practices’ or a constellation of connections that engage and participate.

H810: Seale Chapter 13 : issues identified in relation to creating accessible e-learning for students with disabilities

Bill%2520Murray%2520Groundhog%2520Day.JPG

Fig.1 Groundhog Day staring Bill Murray

At what point does the protagonist in the film 'Groundhog Day' -  TV weatherman Phil Connors played by Bill Murray - unite the Punxsutawney community? How does he do it? And what does this tell you about communities of practice? (Wenger 1998)

Chick%2520Peas%25201.JPG

Fig. 2. Chick Peas - a metaphor for the potential congealing effect of 'reificaiton'

Issues related to creating accessible e-learning

Pour some dry chickpeas into a tall container such as a measuring jug add water and leave to soak overnight. The result is that the chickpeas swell so tightly together that they are immovable unless you prize them out with a knife - sometimes the communities of practice are embedded and immovable and the only answer could be a bulldozer - literally to tear down the buildings and start again.

'Congealing experiences into thingness'. Seale (2006:179) or derived from Wenger (1998)

This is what happens when 'reification causes inertia' Wenger in Seale (2006:189).

'Reification' is the treatment of something abstract as a material or concrete thing. Britannica, 2012.

To ‘reify’ it to thingify’. Chandler (2000) , ‘it’s a linguistic categorization, its the conceptualization of spheres of influence, such as ‘social’,’educational’ or ‘technological’.’ (ibid)

'Reification creates points of focus around which the negotiation of meaning becomes organized'. Seale (2006)

It has taken over a century for a car to be tested that can take a blind person from a to b - the huge data processing requirements used to scan the road ahead could surely be harnessed to 'scan the road ahead' to make learning  materials that have already been digitised more accessible.

Participating and reification - by doing you give abstract concepts form.

1) Institutional and individual factors need to be considered simultaneously.
2) Inclusivity (and equity), rather than disability and impairments, should be the perspective i.e. the fix is with society rather than the individual.
3) Evidence based.
4) Multifaceted approach.
5) Cultural and systemic change at both policy and practice levels.
6) Social mobility and lifelong learning were ambitions of Peter Mandelson (2009).
7) Nothing should be put or left in isolation - workshops with children from the British Dyslexia Association included self-esteem, literacy, numeracy, study skills and best use of technology.
8) Encouraging diversity, equity of access and student access.
9) Methods should be adapted to suit the circumstances under which they are being applied.
10) Technical and non-technical people need to work together to tackle the problems.
11) A shared repertoire of community practices ...
12) Design for participation not use .... so you let the late arrivals to the party in even if they don't drink or smoke (how would you integrated mermaids?)
13) Brokering by those who have multiple memberships of groups - though the greater the number of groups to which they belong the more likely this is all to be tangential.
14) Might I read constellation and even think collegiate?
15) If we think of a solar system rather than a constellation what if most are lifeless and inaccessible?
16) Brokers with legitimacy may cross the boundaries between communities of practice. Wenger (1998)
17) Boundary practices Seale (2003)

John%2520Neill%2520CBE.JPG

Fig. 3. John Niell, CBE, CEO and Group Chairman of UGC

Increasingly I find that corporate and institutional examples of where a huge change has occured are the product of the extraordinary vision and leadership of one person, who advocates putting the individual at the centre of things. Paying lip service to this isn't enough, John Neil CBE, CEO and now Chairman of the Unipart Group of Companies (UGC) called it 'The Unipart Way'.

H810 Activity 36.1 Make notes in response to the following questions:

Visible to anyone in the world
Edited by Jonathan Vernon, Friday, 4 Jan 2013, 13:45
  1. What artefacts inside and outside your organisation have created (or could create) points of focus for you and your colleagues when it comes to developing accessible learning resources?

Examples of internal artefacts might include a policy, an inaccessible resource that a student has complained about or a new module outline that you are developing.

Examples of external artefacts might include an article you have read, a proprietary authoring tool or guidelines on a website.

(AGENCY = a 50 or less web agency that specialises in the creation of e-learning. Some the 'Kall-Kwik' for e-learning, what would have been leaflets, posters, linear video or afternoon workshops turned into e-learning on a tight budget and schedule - slick production in a team of six+ specialists - previously linear video for facilitated workshops, or video with a workbook, then interactive on disc, before moving to intranets and online.)

(CLIENT = a national or multinational of 10,000+ employees hungry for training, both compliance and management training. Keen to exploit e-learning tools and eagerly trying to use social learning too. I have worked for very many and inside a few.)

Professionally I have worked 20 years in the latter and 2 years in the former.

(SWIMMING = from the perspective of a 1000+ club that is five clubs in one offering: teaching and competitive swimming, mastes, waterpolo and disability swimming. As a coach and club officer I have been involved in teaching, coaching, swimming, implementing change and undertaking every four years a mamoth audit called 'Swim21' that leads to the creation of an Improvement Plan. Equity, Disability and Child Protection, Data Protection and Personal Development are key relevant issues)

AGENCY -  Style Guide, ISO 9000?, Web Usability, Training, Experience, Exposure …

CLIENT - Style Guide, Mission, Vision, Corporate Responsibility …

SWIMMING - Improvement Plan for Swim21, Disability Officer Role Description, National Disability Classification for competitive swimmers, CPD as workshops and online. Two groups of for disabled swimmers. Regional hub. +ve/-ve outcomes of the Paralympics.

  1. Are there any artefacts that you think you and your colleagues have over-relied on or misused to the point that they are now negatively influencing your practice? If so, why do you think this is?

AGENCY - JAWS Screenreader, the browser will sought it out …  a PDF once we’ve finished.

CLIENT - policy and a person, Style Guide

SWIMMING - Swim21, the experience of those working with disabled people.

  1. Is there any evidence for mutual engagement, joint enterprise or shared repertoire in the community (or communities) you belong to?

AGENCY - none

CLIENT - token, until you see Take3 video

SWIMMING - with local special needs schools, severe disabilities, dyslexia and in mainstream.

  1. What has influenced whether or not the people in your community are all working in pursuit of the same accessibility enterprise or objective?

AGENCY - None

CLIENT - HR by organisation

SWIMMING - forcing hand to get one or one or two into an equity course, more onto disability and as a requirement onto child protection which is relevant.

  1. Seale discusses the development of accessibility within an organisation as the creation of a constellation of practice rather than a community of practice. How helpful do you think this approach is?

AGENCY - piecemeal, turn it on like a switch, distraction for the most junior.

CLIENT -  probably

SWIMMING - Yes, with the ASA the sun, outlying planets and their satellites.

Yes, as the efforts of one trying to be everyone and be everywhere doesn’t work, not will a constellation of people in silos.

  1. Do you think that the model shown in Figure 13.1 on page 182 would be useful as a trigger for discussion within your organisation?

The McKinsey model also highlights the fact that, in creating whole organisational change, attention must be paid to different elements of the organisation. This supports our findings about the need to take a multi-pronged approach, be systematic and holistic, take an embedded approach, and target multiple institutional functions. May and Bridger (2010:96) The Seale (2006) puts people into silos.
wOhgQDScZW1CVLZp-CEPPukk4ri8mnc--5J4yVM5Zy7Kw6RI65ExQzCrAdYOyBEn94jbyhzC6E7i6cp2TeMtdIXgaCFPzWGPeyCpKm8GmrvqE5QS5GB5J85ottTyQecpq9gyfBE5QQoiXqOAedFiwV0ldo62di6A5NIDsPUB2eJpuKv2cuhnN08G2nSnR3lPBljNFXrYkz0eG9QJ14uH1uqDdAm7pGlSBh1gll8M

I find the constellation of communities works as a metaphor that might be a children’s round-about or the petals of a flower. It gets everything into one place, but it doesn’t suggest how they interact. The MsKinsey 7S model on the other hand, developed by a global management consultancy and regularly applied to organizational and team problems, is a tool that can be understood and applied in your context to help identify and solve complex problems.

See The McKinsey 7S Framework, Mind Tools (1995–2009) http://www.mindtools.com/pages/article/newSTR_91.htm

  1. Would it enable you and your colleagues to identify what changes or developments are needed and why they are needed?

AGENCY - yes, if a crisis occurs or there is a budget to stand back and take a look at what is going on.

CLIENT - bottom line and society …

SWIMMING - audit, action team, top to bottom, holistic, time … introduce, understand, apply.

  1. Would the labels on the figure be different for your organisation? If so, how and why?

Yes, because none of my contexts are in Higher Education. I look at the diagram, then at a room full of people. Many people will be in several ‘communities’ so the model quickly breaks down.

H810 Using an Activity System to improve accessibility to e-learning by students with disabilities.

Visible to anyone in the world
Edited by Jonathan Vernon, Thursday, 20 Dec 2012, 09:45

 

H800%2520Tutor%2520Group%2520Conference%2520FEB-SEPT%25202011.JPG

Fig.1. The consequences of an activity system - loads of action. Here a tutor group over a period of 27 weeks. 'Activity' is represented by messages in a tutor forum. H810 is an Open University postgraduate course in Education. Technology-enhanced learning: practices and debates

Visualizing actions between people, concepts and things required more than words - models and metaphor start to create meaning.

Why use any model?

A model should be a well-founded visual simplification of an aspect of a complex reality that communicates its concept clearly, is based on thorough research, and is easily shared for feedback and review. Users should find that a model, like an experiment, is repeatable so that in time a body of work including case studies and a critique of the model builds credibility. A conceptual model such as an Activity System is ‘particularly useful when one wants to make sense of systemic factors behind seemingly individual and accidental disturbances, deviations, and innovations occurring in the daily practices of workplaces’. Engeström (2008:27)

Conole and Oliver (2011) mention four levels of description:

1. Flat vocabulary
2. More complex vocabulary
3. Classification schemas or models
4. Metaphors

The vocabularly is inevitable, though talking this through to an audience would be my prefered approach, so that with engagement reponse is invited. The models used here, from Vyogtsy and Leon'tev to Engestrom may appear familiar and set - they not. There is a group that likes to see everything 'triangulated' - diamonds and stars, though evident in the literature on education - maybe akin to complex rather than plain language. From models we move to various metaphors - and you are certain to have your own. While Engeström himself moves on to ideas of 'knotworking' and fluid, organic representations.

Engeström (1987) took a current model - that of Vygotsky (1978) and made it his own and has since offered a metaphor to explain it further.

Why use an Activity System?

Activity Systems derive from a century of analysis of the way people construct meaning (Vygotsky, 1978. Leon’tev, 1978) that later researchers applied not simply to how people think, but how groups of people (Engeström, 1987) act in collaborative ways.

 

Engestroms%2520systems%2520model%2520of%2520activity.JPG
Fig.2. Application of Engeström’s (1987) systemic model of activity featured in Seale (2006)

There are two parts to an Activity System - upper and lower. The upper part is the triangle drawn to represent the interaction of Subject, Tools and Object.

Fig.4. The structure of a human activity system. Engeström 1987.

Historically this is where Vygotsky began in Moscow in the late 1920s (Fig.3) Engeström and others turned the experssion of Vygotsky's model the other way up. This split of upper and lower serves another purpose - Yrjö Engeström likens this expression of an activity system to an iceberg where the top triangle - Subject - Tools - Object is what we see, while the other actions, that give the system context - he added when developing Vygostky’s (1978) original model, are beneath the surface. Engeström. (2008:89). (Fig.4) It's worth remembering that Vygotsky was working on how people create meaning, while later thinkers have adapted this to help scrutinise how communities or groups of people, tools and sets of guidelines create (as Engeström puts it above, 'sense meaning' Engeström 1987).

When is the construction of an Activity System useful?

Engeström (2008:27) suggests that it is particularly useful ‘when one wants to make sense of systemic factors behind seemingly individual and accidental disturbances, deviations, and innovations occurring in daily practices of workplaces’. Someone needs to think it is necessary to study the status quo - perhaps because there is an awareness that something, somewhere is going wrong, or that there has been an actual downturn in business or collapse in profitability, or a desire simply to look at things in a different way to understand where improvements can be made, a change in policy and law, or a reinvented or renewed.

Engeström (2008:207) suggests that there are five principles in relation to theories of activity systems.

  1. Object Orientation
  2. Mediation by tools and signs
  3. Mutual constitution of actions and activity
  4. Contradictions and deviations as source of change
  5. Historicity

DSC01597.JPG

Fig. 6 A White Knight from a Lewis Chess Set (replica) playing the role of the Object - the purpose, motivation and idea behind the activity in the system through whom sense is made or an outcome is derived.

1) Object Orientation

The Object is a problem, the purpose, the motivation and opportunity - the modus operandi behind the activity. ‘Object orientation’ (Engeström 2008:222) is a crucial prerequisite of working with an activity system. In the context of accessible e-learning Seale (2006:165) creates an Activity System in which the object(ive) is ‘to make e-learning accessible for disabled students’. As an exercise considering its widest application this object definition suffers because the object is so broad it embraces a myriad of issues and circumstances, each word is open to interpretation - what, for example, is meant by ‘e-learning’, what is meant by ‘accessible’ by ‘disabled’ and by ‘student’. Rather than an object as an opportunity or goal as Seale uses, a fix, the desired outcome, is more likely to be found where, at least in the first instance, we identify a particular context and a tightly defined problem.

Not only that, but to contain the likelihood of ‘ruptures’ across the activity system clarity and agreement is required on the problem that needs to be fixed. In relation to accessibility to e-learning for students with disabilities there are multiple problems, many unique to a student with a particular disability or, where feasible and appropriate, a group that can be identified by the nature of their disability, for example, deaf students who are seen as, and many want to see themselves as a ‘minority language’ group. What is more, a disabled student may have several impairments and the degree to which these are a barrier to e-learning is fluid, perhaps ameliorating with treatment, or getting worse, transmogrifying, or simply being intermittent. As these are known issues that would cause problems or clashes within the activity system and prevent its working it seems futile to build an activity system on this basis - knowing that it will fail.

A problem well stated is a problem half-solved’. (Charles Kettering)

This may be an aphorism, but it rings true. Problem scoping is necessary but where a problem remains elusive, or is ‘messy’ rather than ‘tame’ (Rittel and Webber's 1973, Ackoff 1979, Ritchey 2011) a variety of creative problem solving techniques (VanGundy, 1988. Griggs, 1985). Knowing what the problem is enables innovation - identifying the problem and devising a fix, and in communications, where, for example, advertisers prepare a creative brief that begins by clearly identifying the problem.

‘Object orientation’ and in this context, problem definition and refinement, is the first in five principles set out by Engeström (2008:207) for using activity systems. The drive, purpose and motivation for all the actions between the six identified nodes depends on the object ‘that which is acted upon’. A key component of activity theory is the transformation of this object into an outcome i.e. to solve the problem. If solving a problem is the goal, and recognition of a successful enterprise undertaken, then all the more reason to get the definition of the object correct - the process can be repeated for different problems, at different scales and over time. Without absolute clarity over the object you may find that different people in the system have differing interpretations of what it is. Kuutti (1996) found that having more than one object under scrutiny was a reason for an activity system to fail.  An answer where there are two distinct problems may be to treat them as such and attach them to separate activity systems. Whilst for the sake of scrutiny it is necessary to isolate an activity system, they do of course interact - indeed it is by looking at how two activity systems interact that you may reveal how problems are solved or innovations produced. However, if the object is wrong, or ill-defined or ambiguous then the motives may be out of kilter and it would therefore be necessary to transform all of the components of the activity system, especially and including those at the bottom half of the ‘iceberg’. Engeström (2008:87)

DSC01603.JPG

Fig. 7. The black Queen from a Lewis Chess Set representing 'Tools'

2) Mediation by Tools and Signs

Tools might be evaluation and repair tools and assistive technologies, software or legislation, guidelines or staff development. Tools are a mediating factor between the Subject (student, lecturer, facilitator of the desire outcome) and the Object - the purpose of all this activity.

Tools play a significant role in the history of tackling accessibility issues, to undue, out do or transform resources or interpret platforms in a way that communicates their meaning offering some if not all the affordances of the tools as designed for students, who, having gained a place to study a degree  in Higher Education might be thought of as some the most able’, not simply the ‘able’.Tools in this role at the apex of the Activity System and can include guidelines and legislation where they are an applied ‘tool’ rather than a rule or standard. ‘ A functioning tool for the analysis of teams and organisations’. Engeström  (2008:229) Of course the category includes evaluation and repair tools, assistive technologies and software and equipment. Tools ‘mediate’ between the Subject - the facilitator of change through activity and the outcome of the activities - the Object. ‘To build a website that complies to level AAA’ may be achievable whilst ‘to make e-learning accessible for disabled students’ Seale (2006smile sounds like wishful thinking, rather ‘to build an e-learning module that when scrutinised by a representative range of people with dyslexia’ receives a grading of ‘satisfactory’ or above’. This would suggest the involvement therefore of dyslexic students in the testing of a navigation interface for the virtual learning environment as an ‘action’ between subject and object.

There is a particular congregation of ‘contradictions’ stemming from the relationship between Tools and both Subject and Object:

  1. The array of design and evaluation software applications (Seale, 2006)
  2. The mastery of external devices and tools of labour activity (Nardi, 1996)
  3. No rules of practice for use of that tool (Isscroft and Scanlan, 2002 )
  4. Tools that are overly prescriptive (Phipps et al, 2005)
  5. How do you choose from amongst such a plethora of tools?
  6. The context in which tools are introduced (Seale, 2006:160)

3) Mutual constitution of actions and activity

The links between each component - object, tool, subject and so on - should equate to a burst of electricity or perhaps a chemical induced response between a synapse and a neuron - Engestrom (2008) goes as far as to liken an activity system to a type of fungi - mycorrhizae like formation  Engestrom (1997).

 

Capture%2520Chondrus%2520Crispus%2520as%2520a%2520visualisation%2520of%2520a%2520Social%2520Media%2520Network.JPG

Fig.8. Mycorrhizae - one way Engeström sees an Activity System

An Activity System should be seen not as a concept of a static entity, but rather a living and growing thing. The actions, the double-arrows between each concept, are what gives an activity system structure  - it’s the management  of the disturbances, contradictions and conflicts along these lines of action that disturb effective flow where the role of an activity system comes in - identify then fix these and you move towards achieving the object orientation or outcome. Knorr-Cetina (2003) talks of 'flow architecture' and if neither of these concepts ring true for you in realtion to activity systems then Zerubavel (1997) talks of 'a mindscape' while Cussins (1992) talks of 'cogntive trails'.

4) Contradictions and deviations as source of change

I would have opted for Subject as the third issue, but reading Engeström made me think again. Subject, Tools, Object reduces the Activity System to the far simpler upturned triangle Vygotsky devised to explain how people create meaning (Vygotsky, 1978:86)  without further thought to the deeper and wider issues once learning is put in context, that Engeström (1987, 2008, 2011) added by broadening this way of showing how ‘meaning is created’ in the workplace by adding Rules, Community and Division of Labour.

Rather than picking one more of these concepts at the expense of leaving the others out I think that the ‘Actions’ the double arrows that indicate something happening between the elements is of interest. I believe this would be the fourth of Engeström's five principles - Contradictions and deviations as source of change. This after all is, literally, where all the ‘action’ takes place, what Seale (2006:164) describes as ‘problems, ruptures, breakdowns or clashes’.  (I need to go back and to understand what is meant by Engeström's third principle - ‘Mutual constitution of actions and activity’) I think this is the principle that the Activity System has to be seen as a complete, self-contained entity, that any break or failure or misunderstanding in the system would call it to fail so you’d be better of starting again from scratch until the scale or context works. Engeström uses the metaphor of a very particular kind of lichen (‘mycorrhizae’, Engeström, 2008:229) to describe Activity Systems - he doesn’t suggest however that you attempt to work with this kind of complexity, rather it is a reminder that an activity system is fluid and changing and depends on activity taking places between the defined nodes.

5) Historicity

DSC06471.JPG

Fig. 9. A discontinuous series of Activity Systems ... like Toblerone at Christmas.

'Historicity' - Engeström's experssion (2008) - is a term referring to 'the historical actuality of persons and events',(Wikipedia, 2012) suggests the need to see an Activity System as a snapshot, a sequence and a discontinuous one at that. So take the familiar equilateral triangle of the Activity System model and run a line of them. Seale (2006) suggests there is value to be found by doing some 'archaelogy' - I think 'historical research' would be an adequate way to think of it, for what this may reveal about how these 'rupture, conflicts' Seale (ibid) or 'contraditions and devistions as a source or change' Engeström (2008:223) along the lines of activity. Seale (2006) talks of how an activity system 'incesstanly reconstructs itself. Engeström (1994) talks of an ideal-typical sequence of epistemic actgions in an expansive cycle.

Subject

By definition here the ‘non-disabled’, particularly in the cognitive sense though sometimes with athletic promise too. Ironically whilst ‘non-disabled’ is not a favoured term it does at least relate to a homogenous group, while ‘disabled’ does not given the range, scale and potentially shifting nature of impairments to learning from hearing, to visual, cognitive and mobility.

Subject to be of most importance - this is the person, actor or lecturer, indeed a student - anyone who is responsible for facilitating and supporting the student’s learning experience. This may be a practitioner who works with a Higher Education Learning Technologist or the digital media access group if there is such a thing. Engeström (2008:222).

Any of the team members may be a novice, which may be a positive or negative influence for the actions in the system. A novice is inexpert, on the other hand they are free from the habits that may be causing problems and creating barriers. Because of the way a novice learns they are more inclined to innovate as they are not bound or even aware to rules, guidelines and beliefs that may hold them back.

Rules

DSC01596.JPG

Fig. 10 A collection of pawns from a Lewis Chess set representing 'Rules'

These can be formal, informal or technical rules. They are institutional and departmental policies and strategies. These are rules of practice, and legislation, as well as strategies and research. They are explicit and implicit norms. These are conventions and social relations. These in the context of accessible e-learning are the various guidelines related to web usability and legislation related to accessibility and equality. Universal Design and User Centred Design are rules too. Rules mediate between the subject and the community. The actions, the 'doing in order to transform something' or 'doing with a purpose' are the activities that link Rules with Subject, Rules with Object and Rules with Community.

Community

DSC01594.JPG

 

Fig. 11. An Activity System represented by chess pieces.This 'Community' comprises the King and two bishops from replica of the Lewis Chess Set.

These are 'people who share the same objective' - their being in this activity system is dependent on their wishing to engage with the object, the opportunity, to strive to achieve the stated outcome. Any ruptures are therefore not a consequence of having the wrong person in this community - this grouping, this loose gathering of like-minded people, is what Engestrom has come to describe as a knot and the actions these people take as 'knotworking' Engeström (2008:194) - latent, informal, sometimes impromptu gatherings of people who assemble to address a problem or to take an opportunity - what Rheingold (2002) describes as 'smart mobs'.

Division of Labor (sic)This concept, or node as an ethereal entity is 'how people are organized to realise the object'. Not one to represent by a chess piece and one may think that this ought to be the link that joins people together ... this is where working with a model as the beat of a heart, not the heart itself, requires acceptance of the way a model is designed to work. Division of labor (US spelling for a Finnish academic ... who has bases in Helsinki and San Diego). This is planning and funding, designing and developing, implementing and evaluating, using, specialists vs. the mainstream).

Conclusion

Digitization of assets is akin to the creation of an ocean in which the binary code are the molecules of water - apt then with the shift from Web 1.0 to Web 2.0 and our adopting the use of ‘the Cloud’ and ‘Cloud Computing’ to take this metaphor into a more dynamic form and think of it as a water-cycle. This system is shifting continually horizontally with currents and tides, but also vertically - the exponential growth in computing speeds and memory capacities the energy that drives the system. This global system hasn’t taken adequate account of people with disabilities - as in the real world there are barriers to access caused by visual, hearing, mobility and cognitive impairments - just as these have been addressed in a piecemeal way through legislation, funding, programmes and promotions, by disability groups or holistically, so too with adaptations or changes to the digital world - there is no panacea that will remove all barriers for all people with any disability, of any kind, type or stage of deterioration or amelioration.  Stretching the metaphor further I wonder if at times this digital water-cycle, again like the real one, is polluted, that translucence as well as flotsam and jetsam in this ocean are the barriers - on the one hand the pollutants have to be removed - the barriers taken down - but at the same time, cleaner purer water, in the form a universal design that is simpler and usable would gradually cleanse some of system. Once again, a mirror to the real world responses, specialist schools and associations, say for those with dyslexia are blind or deaf, become an oasis or island in this digital system. 

‘Those not engaging with technologies or without access are getting left further and further behind. We need to be mindful that the egalitarian, liberal view of new technologies is a myth; power and dynamics remain, niches develop and evolve. Applications of metaphorical notions of ecology, culture and politics can help us better understand and deal with these complexities'. (Conole. 2011:410)

H810 : Conflicts in an Activity System

Visible to anyone in the world
Edited by Jonathan Vernon, Friday, 2 May 2014, 13:23

Fig. 1 Seale (2008) chapter 12 on activity systems in relation to accessibility in e-learning as an Activity System

The six potential areas of conflict Seal identifies occur, from the Activity System, between:

  1. Objects and tools - if we agree that the tools currently available are weak (or too many of them, or too specialist or too expensive)
  2. Objects and division of labour - a fragmented division of labour that is pulling the different stakeholders apart and preventing them from working together to meet the objective.
  3. Community and division of labour - a contradiction could be perceived to exist between community and division of labour if the rules that the community develop divide labour in such a way as to mitigate against the objective of the activity being achieved
  4. Community and rules - a conflict with the community whether guidelines are seen as tools or rules. A contradiction may be perceived to occur between community and rules where the community cannot agree on the rules and how they should be applie
  5. Rules and subject - where the rules or guidelines are not specific to the object, or difficulties in interpreting the results having used tools. A contradiction may be perceived to occur between the rules and the subject where the rules are non-existent, weak or inconsistent and so not good enough to enable the users of the rules (subjects) to meet the objective of the activity.
  6. Tools and subject - If the subjects of an activity system are unable to use the tools in the way they were intended, then conflict or contradiction may occur.

There are a further 8 discussed tangetially in relation to the Activity System, some within individual nodes. In total the full list looks like this:

  1. The array of design and evaluation software applications
  2. The mastery of external devices and tools of labour activity (Naardi 1996)
  3. No rules of practive for use of that tool (Iscorft and Scanlon)
  4. Tools that are overly prescriptive (Phipps et al 2005)
  5. How do you choose a tool?
  6. The context in which tools are introduced (Seale, 2006:160)
  7. The array of guidelines and standards and lack of information on how to use these.
  8. Constraints caused by formal, informal and technical  rules and concentions of community (Seale, 2006:161)
  9. A framework for desscribing current practice both individual and social (Seale, 2006:160)
  10. More than one object (Kuutti, 1996)
  11. When different but conntected activities ahre an object or an artefact but place a very different emphasis on it (McAviia and Oliver, 2004)
  12. Conflict over who does what within 'Divisions of Labour'
  13. Novice or expert ... good thing or bad? The novice is more likely to be the innovator - if brought in from outside the system, while the expert in the system may be too set in the ways of the 'community'.
  14. Excuses about the lack of information. Steyaert (2005)

I like Seale's concluding remarks - Subject and object, object and community, subect and community - Contradiction in any or all of the relationships described in the previous section has the potential to threaten the central relationships between object and community, subject and object and subject and community.

And the over all thought:

‘Design for all’ probably requires a commitment to ‘design by all’.

According to Activity Theory, any or all of the contradictions will prevent accessible e-learning practice from developing and therefore accessible e-learning will not develop or progress unless these contradictions are resolved.

To understand Activity Systems I produce tables and charts - I annotate these then revise initial drawings until I have something that is clear. I may fill several sheets. My conviction is that Activty Systems have a great deal to offer when it comes to trying to understand how actions are playing out, producing contradictions and confict.

H810 Activity 27.4 : Alternative formats

Visible to anyone in the world
Edited by Jonathan Vernon, Friday, 4 Jan 2013, 19:49

Read this web page and consider to what extent the six challenges mentioned are addressed in your context:

Mis-Adventures in Alt Format (Stewart, 2007)
http://www.altformat.org/index.asp?id=119&pid=222&ipname=GB

Pick one challenge and write a paragraph in your tutor group wiki explaining how it is relevant to your context.  
____________

Developing a total picture of how Alt Format fits into the broader discussion of curricular reform and modernization will help insure that we do not continue to live on the margins of the educational mainstream. (Stewart, 2007)

'Universal Design for Learning'

Challenges in relation to Alternative Formats:

  1. How does the provision of Alt Format fit into other emerging models for data management and delivery?
  2. How do we build systemic capacity to meet the projected needs for Alt Format and Accessible Curricular Materials?
  3. How do we align the divergent Alt Format efforts occurring on an international bases so that they minimize redundancies and duplicative efforts?
  4. How do we move beyond the current focus on Blind and Visual disabilities to a more holistic model of access for the gamut of print disabilities?
  5. How do we develop the level of technological literacy in students with print disabilities that will be necessary for them to benefit from the technological evolutions that are occurring in curricular access?
  6. How do we involve all of the curricular decision makers in the process of providing fully accessible materials?

In my context


1) How does the provision of Alt Format fit into other emerging models for data management and delivery?

With the digitization of everything a further step to ensure content is also accessible should be taken at the time of conversation or creation. I’m not aware in an agency where this ever occurs and when there is a client request the response is a simple one - word or PDF formats, or look to the browser of platform where the content will sti.

2) How do we build systemic capacity to meet the projected needs for Alt Format and Accessible Curricular Materials?

Is there a more appropriate agent to handle the conversion and delivery of electronic content on a given campus or system of campuses? I’d probably consider the Open University itself, or the Business School where I worked for a while. I know the disability officer, but his role was more to do with access and personnel and visitors to the building then meeting student needs - which I presume comes under Student Services.

3) How do we align the divergent Alt Format efforts occurring on an international bases so that they minimize redundancies and duplicative efforts?

Whilst efforts can and have to be made to improve access universally might the fine detail be left to address either group issues by working with representatitives of associations for, for example, the blind, dyslexia, cerebral palsy and other groups ? Learning from then improving such practices and tackling access for people from these groups for specific subjects and specific levels on a strategic basis knowing that complete coverage is the goal?

‘A plan for the development and incorporation of emerging technologies in a holistic and self-sustaining model is incumbent. These emerging systems must be based on flexibility and economies of scale if we are ever going to get in front of the issues of materials access.’ (Stewart, 2007)

4) How do we move beyond the current focus on Blind and Visual disabilities to a more holistic model of access for the gamut of print disabilities?

Doesn’t cover everyone who would benefit and would benefit other groups, such as non-native language populations, remedial groups and as an alternative for any user who may prefer or benefit from the text record.

5) How do we develop the level of technological literacy in students with print disabilities that will be necessary for them to benefit from the technological evolutions that are occurring in curricular access?

In many anecdotal reports, less than 10% of the incoming students to higher education have ever had any realistic exposure to the access technologies they will need to be successful in adult education and in the world of work. (Stewart, 2007)

Current studies suggest the opposite, that students with disabilities who gain so much from having a computer to access resources, that they are digitally literate. There are always people who for all kinds of reasons have had less exposure to or are less familiar with the technology -whether or not they also have a disability.

6) How do we involve all of the curricular decision makers in the process of providing fully accessible materials?

The original authors never have a say or make a contribution to the reversioning of content for use by disabled students.

This method of access often times results in the retrofit of existing materials, or the creation of alternative access methods that are not as efficient or well received in the general classroom environment. (Stewart, 2007)

For a truly effective model to be developed the original curriculum decisions should be made in a context of understanding the needs of all learners, and in particular those learners who do now have visual orientation to the teaching and learning process. (Stewart, 2007)

-----------------------------------------------------------------------------------------------------------

Interview analysis revealed five personal factors that appeared to influence students’ decisions about technology use:

  1. a desire to keep things simple,
  2. a lack of DSA awareness,
  3. self-reliance,
  4. IT skills and digital literacy,
  5. a reluctance to make a fuss.

The three most talked about factors were desire to keep things simple, IT skills and digital literacy. Seal and Draffan (2010:455)

‘The are many ways of making and communicating meaning in the world today.’ Conole (2007:169)

The kind of problems students with disabilities now face are different - less whether content has been made available in a digital format, but how good the tools and services are to access this content.

  • 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.

Students also mentioned technical difficulties using e-learning and connecting to websites and CMS, problems downloading and opening files, web pages that would not load, video clips taking too long to download, poor use of e-learning by professors and their own lack of knowledge  working with elearning.

For most groups of students, solving e-learning problems by using non e-learning solutions was also popular.

During the last decade there has been tremendous development and interest in e-learning on campus. While our research shows the many benefits of e-learning, such as the availability of online course notes, there are also problems. Chief among these are problems related to inaccessibility of websites and course management systems. (Fitchen et al 2009:253)

Digital Agility

Results suggest that an important personal resource that disabled students in the study drew on when using technologies to support their studies was their ‘digital agility’. Seal and Draffan (2010:449)

Use of assistive technologies

Many students with disabilities have, since 2007, developed strategies for the use of both specialist assistive technologies (e.g. IrisPro, quill mouse, Kurzweil, Inspiration or Dragon Dictate) as well as more generic technologies (e.g. mobile phone, DS40 digital recorder, Google) Seal and Draffan (2010:450)

Seal and Draffan (2010:451) therefore suggest that disabled students have the kind of ‘sophisticated awareness’ that Creanor et al. (2006) described when they talked about effective learners being prepared to adapt activities, environments and technologies to suit their own circumstances. This contradicts somewhat the arguments of Stewart who argues that disabled students are behind other students in terms of developing digital literacies.

The digital agility of the students, identified in the study, is significant in terms of encouraging practitioners not to view all disabled students as helpless victims of exclusion. Digital inclusion does not always have to be understood through the dual lenses of deficits and barriers. Seal and Draffan (2010:458)

H810 Activity 27.1 What would you change about the way in which students are supported in your institution and why?

Visible to anyone in the world
Edited by Jonathan Vernon, Wednesday, 5 Dec 2012, 10:52

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.

Common%2520problems%2520and%2520solutions%2520for%2520students%2520with%2520disabilities%2520Fitchen%25202009.JPG

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)

H810 : Activity 26 Designing and developing accessible e-learning experiences: the learning technologist’s perspective.

Visible to anyone in the world
Edited by Jonathan Vernon, Friday, 2 May 2014, 11:42

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.
