The SHARP learning cycle


Just knocked this up for use in a session in a couple of weeks. I like it - wish I had time to say more. Perhaps will come back again and do that. For now, thanks to Peter Goodyear! Here's a 'bit more'...(updated 22/10/2014)
The fairly subversive pedagogy of a networked learning activity rides bareback on the conventional hegemony of the student/staff dichotomy where the students are 'encouraged', almost as an act of faith, to take up the reflective and generative practice of knowledge work; through internalisation and externalisation, they bring their own practice under the reflective scrutiny of authoritative theory. They 'feel their size', and this brings on a minor crisis: it is expected that they will not understand everything they read, they realise that the bar is significantly higher than they had appreciated. Coming to terms with this discomfort is an important aspect of 'affect' in learning. Even to appreciate that 'higher ground' exists may be novel and generative in itself. But, more significantly, the mind is piqued into confusion, frustration, arousal and enquiry. Sense/meaning-making can commence, even if only through a stumbling advance. The 'stumble' metaphor here intentionally implies an iterative wobble 'back and forth', attempting stability, between the theory-laden artefact and the learner's own reified, tentative understanding. It may only be after this that the 'third space', an online forum, is deployed and the shared object(ive) of the scripted task invokes a collective sharing of the experience, providing the learner with contextually rich alternative attempted 'takes' on the theory and its application in practice, not least the practice of learning.
These 'affective' elements of learning are vital for what Illeris (2008,p13) terms,
"accommodative or transcendent learning.", where "one breaks down (parts of) an existing scheme and transforms it so that the new situation can be linked in. Thus one both relinquishes and reconstructs something, and this can be experienced as demanding or even painful, because it is something that requires a strong supply of mental energy... In return... (the learner has) understood"

The ZPD is different to scaffolding, different enough to matter

This post will (may) grow over time but for now I just need to dump some quotes and resources in a place where I can find them again and point 'someone who wants to know more' at with relative ease.

I have found that LS Vygotsky's concept, the Zone of Proximal Development is confused with the concept of scaffolding. Some are prepared to openly assert and strenuously defend the position that scaffolding is Vygotsky's concept. In my reading, it is not. Does this really matter? In my sense of things, yes it does and here's an idea of why... Thankfully, both questions are answered lucidly by Seth Chaklin: here are some extended quotes from a chapter of his from 2003:
I also want to highlight and recommend the paper by Verenikina (2003)... in which she points out, citing Stone (1998), that metaphors, such as 'scaffolding', have the capacity to augment understanding but also to constrain it. That, is a problem. Here we go with Seth anyway:

"Popularity has its price, however. Wertsch (1984) suggested that if this theoretical construct was not elaborated further, then there is a risk that "it will be used loosely and indiscriminately, thereby becoming so amorphous that it loses all explanatory power" (p.7). Mercer and Fisher (1992) believe that "there is a danger that the term is used as little more than a fashionable alternative to Piagetian terminology or the concept of IQ for describing individual differences in attainment or potential" (p. 342). Palinscar (1998) suggests that in the context of research about the negotiated nature of teaching and learning it is "probably one of the most used and least understood constructs to appear in contemporary educational literature" (p.370).
Critique of the common conception:
"If Vygotsky's intention was to use the concept for all kinds of learning, then why not name it the zone of proximal learning?" p40
"Vygotsky..., concluding that there is a unity but not an identity between learning and inner developmental processes. Vygotsky (1987) disctinguishes instruction aimed "toward [the child's] full development from instruction in specialized, technical skills such as typing or riding a bicycle" (p.212). In short, zone of proximal development is not concerned with the development of skill of any particular task, but must be related to development." p40
Assistance assumption
"In other words, it is not the competence per se of the more knowledgeable person that is important; rather, it is to understand the meaning of that assistance in relation to a child's learning and development." p43
p57: "In relation to the school age, the theoretical function of Vygotsky's zone of Proximal development research can be understood as a search for identifying a principled way for conceptualising schooling in relation to the whole child and not just the child's performance on a single task" (as with IQ)
p57 " The zone of proximal development is not simply a way to refer to development through assistance by a more competent other. This assistance is meaningful only in relation to maturing functions needed for transition to the next age period".
p59 most work that refers to zone of proximal development does not have such a developmental theory, even implicitly.
Why not imitation, assisted instruction, or collaboration? Is it because neither of these terms hold the same scientistic mystique necessary to attain the desired level of rhetorical capital needed so as to bolster their argument?

On 'educationally driven' interventions

I have an idea for doing something within a module about educational media in terms of learning about the sphere of 'mobile'. Of course the activity has to clearly give the message that starting with the tech is 'bad' for lots of sound reasons. For example, since we have no chance of researching an innovation before it's out of date, the only way to hold on to some sense of purpose is to ground the project in a deliberate philosophy of education and work forward from there. There are any number of solutions out there needing a problem and the only rational angle of attack is to ask, 'what would you like to do'? There is a view that this is the only pure approach to doing learning technology.
For example, "design has to be generated from the learning objectives and aspirations of the course, rather than from the capability of the technology" (Laurillard, 2002, p 145) However, Peter Goodyear (2006) maintains that there is "no great harm in this, it is part of a vibrant process that explores and advances frontiers of application. Solutions should look for problems." (emphasis in the original)
However, if we consider the methods and philosophy behind participatory and/or spiral design approaches and principles, there has to be an ongoing 'conversation' between the problem and the solution, between the designer and those being designed for. One has to inform the other - posh word for this would be a 'dialectic'.
Spiral Stair
Our knowledge and understanding of and in the world can shape our thoughts and actions without our realising it. An idea may be sparked by noticing something a technology can do differently, but the sparking of the idea will have happened because of the knowledge and understanding of the relationships between the technology and the field it is being applied to. So which way around was that then? Technology first or context/practice/theory first? I'm not talking about some blind determinism that shuts my mind to ignoring and/or conflating all sorts of unintended consequences and factors, or gives way too much agency to the technology. But in what world does any idea begin from a really pure educationally driver, and stay that way for very long? I'm arguing that we should recognise the inconsistencies in ourselves and the world around us and embrace the dialectic, including the distinct possibility that a really good educational technology idea may have come about empirically and it's only afterwards that we can trace the strands of 'good' theory which contributed to the idea. This is not the 'wrong way around', it may be an attempt to side-step the sometimes crushing burden of proof required by the same educationalists, who, in other settings, would be seen fervently espousing the need for ideation and innovation in education.
So, dialectics FTW!

Brad Mehlenbacher's Five Dimensions of everyday instructional situations


I've been trying to finish this book for review for over a year now. Recently I had a little push to get through the 137 page sixth chapter. In a previous chapter the author critiques several 'models' of learning with technology as simplistic. I wanted to use the 'Five dimensions' diagram, and decided to create a copy using googledocs. With reference to the design of the graphic, Mehlenbacher says (pp199-200):
Because our goal is to capture the fundamental dimensions of everyday instructional situations initially, it is not necessary to explicitly define where one dimension ends and where another begins, nor is it necessary to capture the rich interplay between dimensions. In the manner of an Escher print, figure 6.1 represents the five dimensions of everyday instructional situations graphically, suggesting how one or more dimensions, when grounding another, serve to figure the dimension under investigation. Thus an instructor interested in engaging learners in higher-level research activities might construct a simulated publishing environment that emphasizes collaborative peer review and conceptualize issues related to learner background and knowledge, tasks and activities, social dynamics, and environment and artifacts under instructor activities. Still, to one degree or another, all five dimensions are required to produce an everyday instructional situation. 
Figure 6.1 appears to be a tessellation; tessellations, however, involve repeated use of a single shape to cover a plane surface, without gaps or overlapping between the shapes, like the tiles of a washroom floor. Tessellations cannot have any gaps and cannot overlap on another, as does this particular noncircular Venn diagram. Hexagons, squares, and triangles can tessellate; octagons and pentagons cannot. And instruction and learning with technology can be improved in certain situations and not in others, lacking as tessellations do mathematical precision and replicability. 
What I like about this is the brave attempt to represents the complexity of learning and instruction.

When is learning not networked learning?

Networked learning is not a theory of everything... I think I verge on making that mistake when I talked about 'promoting connections'... in the minds and lives of students and staff, and things you do to promote connections to the point that they engage with/in networked learning. I believe that is vital to bring them to the feast and so it is relevant and foundational, even a pre-condition to it, but not essentially networked learning.
And, in a similar way, I'm not convinced it's useful to extend Personal Learning Environments (PLE) as including 'everything', even if it does temporarily cause us to reflect on the differences between PLE's and VLE's, and how people configure their whole learning environment.
Part of the problem is that learning is very complex in humans and they're doing it a lot, to various degrees...
Recently I was reading a bit of Peter Alheit and when his use of the term 'networked learning' caught my attention:
What do you think...? How is the following 'networked learning'? p117
The purpose behind this new understanding of the term 'learning' is the option of networking these different forms of learning in a synergistic way - learning should not only be systematcially extended to cover the entire lifespan, but should also take place 'lifewide', i.e. learning environments should be engendered in which the various types of learning can complement each other organically. 'The "lifewide" dimension brings the complementarity of formal, non-formal and informal learning into sharper focus' (Commission, 2000, p9.)
Lifelong, 'networked' learning thus seems to become an economic and social imperative of the first degree. The 'new' concept of lifelong learning betrays an ambition that John Field has termed 'the new educational order' (Field, 2000, pp.133ff). Learning acquires a new meaning - for society as a whole, for education and training institutions and for individuals. The shift in connotation exposes an inner contradiction, however, in that this new learning is initially 'framed' by political and economic precepts. The goals are competitiveness, employment and adaptive competence on the part of the workforce. The intention is also, however, to strengthen freedom of biographical planning and the social involvement of individuals. Lifelong learning 'instrumentalises' and 'emancipates' at one and the same time.
This seems to put a high price on 'networking' formal, informal and non-formal learning.... which is haunting me somewhat... Is 'networking' here just another word for 'including' or 'linking', etc. and thus a mere co-incidence, or does it have something important to say to the concept that is the subject of this blog? Right now, it strikes me as pitching for another [learning] 'theory of everything'.... (sorry Peter - probably 'my bad')
As trends in learning theory move from behaviourist, cognitivist, and social learning, the lens shifts to such a wide angle that, in the end, one is depicting 'life', rather than 'learning'. But I think it also happens when I get over-excited about an insight or idea I've just grasped (or re-grasped) so that 'learning theory myopia' (or is it hyperopia!?!) kicks in, and, suddenly, I see nothing else - for a while at least!
