In using the term ‘online’ learning I follow Paulson (2002):
• “the separation of teachers and learners which distinguishes it from face-to-face education
• the influence of an educational organization which distinguishes it from self-study and private tutoring
• the use of a computer network to present or distribute some educational content
• the provision of two-way communication via a computer network so that students may benefit from communication with each other, teachers, and staff”.

online communities
There are three factors which I shall use to provide the background for an evaluation of online learning environments.
Firstly there needs to be an understanding on the part of the learners as to whether the PLE has been adequately established because without this there is a lessened possibility of effective communication in a virtual environment.
As this is a prerequisite, I refer the reader to Scott Leslie’s compilation of PLE options. This is the most exhaustive list of PLE options of which I am aware.
Which PLE options are chosen by the learner is of less significance than that process of reflection leading to the choice of a PLE which will be inevitably an ongoing dynamic process as more and more options are added to Web 2.0 and as future developments in the direction of Web3D occur.
Secondly the elements constituting the VLE need to be made clear. The presence or absence of key communication channels limits the chance of effective communication online. Wilson’s (2005) outline of a typical future VLE is my starting point here:

Scott Wilson: future VLE
Thirdly I want to avoid the terms friendship, virtual and real because they are overused, tired words which appear to have lost precision of meaning in online learning contexts. Therefore in looking at communicative differences in face-to-face communication and online communication I shall use the terms: allies for ‘friends’, cybernetic for ‘virtual’ and traditional for ‘real’. (Cybernetic is a term borrowed from Ananda Mitra and Rae Lynn Schwartz.
It seems to me that allies is more suitable than friends but my understanding of friendship goes deeper than that of a facebook page link. I think there is potential confusion in using the word virtual because of the confusion between virtual participant worlds and virtual reality complete with headpiece. To use the term real world carries the implication that the cybernetic world is unreal and consequently prejudges what I am considering here.
From a carefully selected PLE linked to an institutionalized VLE the learner can then communicate with his allies in the learning process online in the cybernetic world.
Irrespective of the technological hurdles which need to be crossed and new techniques which need to be learnt, the learner is likely to be faced with hauntological problems. Derrida’s citing of Hamlet’s: ‘The time is out of joint’, states the likely effect on the learner.

Exploding clock: Dali
To further cite Tribe:
“Hauntology is a coming to terms with the permanence of our (dis)possession, the inevitability of dyschronia… We live in a time when the past is present, and the present is saturated with the past…”
“…Modernity was built upon ‘technologies that made us all ghosts’, and postmodernity could be defined as the succumbing of historical time to the spectral time of recording devices.”
This takes us to the heart of the cybernetic learning experience. As Palloff and Pratt put it; online learning is the ‘separation of instructor and learner in space and time’. Further, there are “connections through educational media – where the learner takes an active role in the learning process”.
In their discussion of VLEs, Dillenbourg, Schneider and Synteta inform us that the learner finds him/herself in a designed information space called a VLE, which is social and where environmental interactions turn spaces into places. It could be textual or a 3D world. Most likely it will be a mixture of both. Not only will the students be active but they will be co-builders of that cybernetic space.
From McConnell’s ‘Comparison of Online and Face-to-face Learning Environments’ and my own reflection, I have selected those points which seem to me to be most closely linked to the cybernetic communication experience:
There is relative freedom from instructor control outside of the given activity parameters. Although text-based discussions can be rather Spartan in content they can be enlivened by audio, visual and audio-visual input. Social networking mediums add to the variety of discussion offered. Meeting is primarily random unless a virtual classroom, audio or video conference is used. The participation is relatively free in terms of time constraints. The thematic work flow is primarily multiple and fluid. The group contact can be as regular as individually required and discussion groups and social networking offer a dynamic discussion environment with the chance to withdraw to reflect before responding. There is great analytic depth although sometimes at the expense of information overload.
The lack of a shared physical context means that there is an absence of visual and intonation clues and this would seem to point to the need for the further development of live, audio-visual communication systems for online learning, despite the cost. This would be the one significant change which I would want to be made to the course which I have just experienced on the MSc programme at Edinburgh. Such conferencing would need to be selectively used however because otherwise the benefits of online learning would be lessened, for example, the ability to lurk until confidence has increased and the opportunity to reflect before responding.

reflection
There is clearly an impact from the software and the medium which manifests itself positively in broader, more even participation, rich, considered and varied feedback. Feedback is open, widespread and permanent.
When a participant feels short of ideas there are always search possibilities at the fingertips and the possibility to tune into parallel or similar discussion groups to feel ones way back into the groove. This is also important after an enforced absence when the stress of rejoining is relatively high.
The greatest attraction in online learning is the open, creative structure and the adventurousness with which the learning experience can be approached.
To quote Simon Young (2008):
“There’s a myth around that the “virtual world” is somehow a different place from the real world we all live in.
Interestingly, it’s a myth found only among those who haven’t tried out social media and social networks. Once you dip your toe in the online conversation, you find that blogs, Facebook, Twitter – and on and on – are all elaborations on (not replacements of) the art of one human relating to another.”
Bullen (1998) found a conflicting reaction:
“On the negative side, however, for some students there was also a sense that the inherent delays in asynchronous communication militate against the development of a dynamic and interactive online discussion, that this form of communication was not real, that it did not adequately simulate a face-to-face discussion, and that it left them feeling remote, detached, and isolated, and this discouraged them from participating. (Student #15)”
My personal experience suggests that the preparation behind the introduction to online communication experiences is vital. I needed and received, a handbook to prepare me for the experience, divided into technical and course content and two experts: one for content and one for technical questions; this lessened the culture shock effectively and efficiently and led me to conclude that the learning experiences are different; neither better nor worse than one another.
Kassop (2003) listed ten key advantages of online learning: student centred, greater writing intensity, highly interactive discussions, geared to lifelong learning, enriched course materials, on-demand interaction and support services, immediate feedback, flexibility, an intimate community of learners and faculty development and rejuvenation. From personal experience I know the first nine to be accurate depictions.
Bricken (13) writing in 1990 saw the next logical step in educational experience to be virtual reality.

virtusphere
A situation in which symbol processing became reality generation, viewing a monitor was replaced by wearing a computer, the symbolic became experiential, the observer became the participant, interface was replaced by inclusion, the physical became programmable, the visual became multimodal and metaphor was replaced by virtuality. In Virtual Worlds part of this has come true; the rest may follow.
The KnowledgeWorks Foundation together with the Institute for the Future have produced a forecast for education in 2020 called ‘Creating the Future of Learning’. It is labyrinthine in format so I have selected key aspects to discuss. It starts with the assertion that “the most vibrant innovations are likely to take place outside of traditional institutions”. For those organizations a dilemma is thus presented. It goes on to suggest that the “educitizens” of the future will define their rights as learners and re-create the civic sphere; that neuroscience will advance new notions of performance and cognition which will reshape both social justice and learning. Referring to schools (learning institutions) it says that they will become, at best, dynamic community-wide systems and networks that have the capacity to replenish themselves in the context of change.
I have listed these points because they seem to me to harmonize with the direction online education is taking and will continue to take. In video ten of their 2009 summit they acknowledge that this futuristic view is in fact a best practice compendium of what is already possible but not yet common currency.
The ‘vibrant innovations’ are taking place in open sourceware and becoming part of both PLEs (e.g. edublogs) and some VLEs (e.g. wikispaces). The PLE aided by web 2.0 tools, has become that defining of learning rights, together with social networking, which is the beginning of the recreation of the civic sphere. New methods of assessment and with them newly defined concepts of performance are already shaping the form of online education. The World Wide Web and the increasing understanding of neural networks have shaped how we learn. The degree to which universities and schools adapt to programmes which meet the needs of these newly enfranchised learners will determine their success as beacons or failures as dinosaurs.
O’Driscoll offers a persuasive and comprehensive argument for learning in three dimensions:
O’Driscoll closed with the statement that the acronym FREEDOM stood for flow, repetition, experimentation, engagement, doing, observing and motivation – all of which virtual worlds offer us.
If he is right then we have inherited a space which allows creativity as defined by Csikszentmihalyi’s concept of flow, trial and error repetition as represented in Piaget’s developmental stages theory, experimentation as theorised by Dewey, Plato’s Socratic form of engagement, doing as in Vygotsky’s zone of proximal development peer-learning theory, the scientific principle of observing and testing hypotheses and motivation according to Maslow’s hierarchy of needs.
In conclusion, this is a highly positive endorsement of what the online world has to offer 21st century learning.
