Essays - The Pain and the Joy

I have recently finished my first MA essay with the title "A critique of instructional design models, theories and specific online interactive and collaborative technology related to online adult distance learning".

Quite a lot to fit into a 3’000 word essay, I chose initially to concentrate on 4 models of online learning and critique them. This it seems would have seriously neglected many themes in the essay i.e. adult learning, distance learning, interactive and collaborative technology. Although a lot of useful ground work was done and preliminary feedback from a colleague was positive it felt boring to just take a model in turn, dissecting it and move onto the next one. After discussion with my mentor a suggestion to write the essay around important themes that could draw in various ideas was quite obviously the way to go. The painful decision (because I’d more or less finished my original essay) to rewrite the essay was absolutely the correct thing to do and I feel I have a much better template now for future essays.

Although I have not gone into as much depth on some areas as I would have liked, I felt as though the essay captured my passionate views on how online learning should be conducted. I felt I gave a logical account for the basis of my views and highlighted how an appropriate model of online learning and associated interactive and collaborative technology could and should be used to achieve effective online learning.

Although i personally i feel i have learnt a lot from researching, planning and organising my thoughts for the essay, the essay is perhaps on reflection not as critical as it could be, although i still feel as though I've done a good job. I hope to use my experience of writing this first essay to make improvements in my critical approach for the next MA essay.

Tagging - A leap into the unknown

Overview

I have just signed up to a bookmark tagging research experiment using the social bookmarking web application del.ico.us.

I don't know fully what to expect and i have no preconceived idea as to what i will learn from the experiment, but i have a feeling that there is something of value in being a part of the experiment and i am hoping i will learn new insights into the use of tagging in respect of how it can be of use in a teaching and learning context.

Tagging is a relatively new way to categorize web pages on the Internet. Rather than saving web pages in a hierarchical fashion in folders and sub folders, by multiple tagging of a website you can search for tags and therefore web pages in as many different categories as you like (i seem to tag about 4-5 categories). With meaningful tags this should make it easier to find and retrieve.

In addition the use of social bookmarking websites such as del.ico.us, allows you to retrieve any tag (bookmark) from any machine, anywhere as it is a web based system. Websites tagged can also be made available to other world wide web users and a myriad of connections to users and their tags can be viewed.

So my interest in being a part of this research is that this process of social bookmarking (tagging) opens up possibilities for collaboration ,widening your own knowledge base and enhancing learning though group interaction.

Our task will be to tag over fifty web pages in five blocks of 10 pages over a 4-6 week period.

First Reaction
After tagging just the first two websites i have had couple of A-ha moments:

1. From a tagging point of view- i started with two tags stories and memories, after the second site i realized it would be more meaningful to tag with a category enhancement as WW2stories and WW2memories. I also included ww2 as a tag for both websites. I am not sure i need to do this as using the searching mechanism it will take me to any category starting with ww2 anyway.

2. It feels that there are learning activities that can be created from this. By being asked to tag the websites meaningfully, i am having to read the website with a little more detail and interest than i would normally. I think this can be used to get students to tag and then some kind of discussion can occur about the tagging afterwards. A thought that has come to me is that rather than tag descriptively, a group could be asked to tag emotionally and we could subsequently discuss what emotional tags where attached to a website article and the reasons why?

After completing the tagging of 10 websites, it seems that not all my tags seem to appear. I am assuming thee is a time delay before they appear otherwise it seems strange. Need to evaluate my naming strategy once i a more familiar with the tools available to me. For example the bundling of tags may be useful as part of a naming and categorizing strategy.

Wiki’s – The Good, The Bad and the Lovely

Well let’s get the lovely bit out of the way. The lovely bit is really the simplicity. With the predefined setup and limited set of commands/ tags it takes a lot of the time wasted over cognitive decisions of design and fretting over technical competence out of the equation, leaving the wiki page author to concentrate on the business in hand, which is the writing.

I’ll address the Good of wiki’s by focusing on the strengths of a wiki. When asked wiki users could come back with many different responses to the question “what are the strengths of a wiki?” I believe the strengths listed below will encapsulate the many responses to this question.

The first three strengths are arguably subjective and could be open to an alternative view. However it is generally accepted through my reading and experience that the following three characteristics of a wiki are indeed it’s strengths in promoting and encouraging group collaboration:

1. Simple technology – only need internet access and a web browser.
2. Simple and easy to use (creating and editing pages, linking to pages and websites, inserting images and documents)
3. Easy to learn how to use

In addition, the following identified strengths are less open to argument, as they are a matter of fact.
4. Easy to rollback and compare with earlier versions (mistakes can be rectified, malicious vandalism can be deleted)
5. All changes are logged and therefore traceable.
6. All members can act as moderators and guardians of the wiki.

So we come to the bad. Bad is really to strong a word for what I want to convey which is that the success or failure of a wiki for all it’s inherent strengths will be determined by how the wiki is used, regulated and valued by it’s users. It is encumbert on the wiki organizers primarily and the wiki participants subsequently to create and maintain a flourishing wiki that achieves it’s purpose.

In order to achieve this wiki organizers need to draw on best research and practice of co-operative/group/ collaborative learning and apply this to wiki teaching and learning activities to gain best results.

How can they do this? Well hopefully I’ll come up with a few ideas in subsequent blog.

I’d rather have a wiki than a Blackboard VLE.

If I had a hammer, er no wrong tape responsibility for delivering a distance learning MA or BA Programme I’d rather have a wiki than a blackboard VLE to administer the programme and to co-ordinate learning activities. For argument’s sake I am going to assume the use of the company wikispaces as my wiki space provider as I am familiar with their service. They will host for many different organisations and all are (can be) connected via wikispaces. (alternatives could include hosting your own in house wiki using ‘Mediawiki’)
  • Starting point for this reasoning is that a very low technical competence is by users is required to use a wiki. This is massively important for staff uptake and enthusiasm in engaging in the promotion of e-learning and to cater for the wide diversity of students that will participate on the programme.
  • Technically simple to setup and simple to access. As it is primarily text based web pages all users need is internet access and a dial up connection will be adequate in many cases.
  • Speed and Fluidity. If a student was enrolled on perhaps 8 Modules BANG, they could flick from one module to another just like THAT.
  • Quick Connections/ Communications. A Message box is available BANG just like THAT to pick up messages related to any other 8 Modules from all students and all tutors involved in the programme and to any external members of the whole wikispaces community. (This could include students and staff on partner programmes in other universities).
  • If any pages on a wiki are changed for example student announcements, then each students can be notified of a change immediately to their email BANG just like THAT. (probably be able to send a message to a mobile phone as well soon).
  • Due to the global nature of the wikispaces community many useful contacts with external friends and colleagues in the same field can be made and then easily continued after university life.
  • The way a wiki is setup and they way the page is structured it makes it very easy to back up all pages in HTML or in original wiki text, which also means a fair amount of future proofing can take place as the text will be saved in a format that is XML compliant and will therefore be easily re purposed in the future for perhaps delivering to mobile phones or PDA’s.
  • Being fluent in wiki skills will be a good life skill to have both for Staff and Students.

This is a pro wiki article. To Blackboard VLE and other VLE's I say TAKE THAT can you compete, ‘Respondez vous sil vous’ plait with counter arguments.

HE Institutional Strategies for E-learning

Well just as higher education embraces the notion of e-learning and start investing heavily financially, strategically and emotionally in commercially driven e-learning VLE’s such as Blackboard along comes those damn pesky web 2.0 technologies. After all the staff and student training that has gone into learning how to make that cumbersome beast (my view) Blackboard be a useful catalyst to promote and develop a sustainable and consistent e-learning strategy it is hard to contemplate that their may be a better way forward other than via Blackboard or similar VLE’s.

Now I am not saying exactly for sure what they way forward is, as I am not privy to the costs involved or the administrative, security and control issues, that said a strategy involving web 2.0 technologies should be piloted and I feel eventually adopted if not totally, but in a dual approach over the next few years because of the simple benefits that web 2.0 technologies can offer both students, but just as importantly to staff.

When one thinks of e-learning, the first thought quite naturally is of learning and probably most people conjure up an image of a wed page or maybe an interactive multimedia application. The crucial thing is from an institutional point of view is that apart from the learning, other very important issues are
• Communication between academic staff-students, administrative staff-students and students to student communication.
• Staff training and development
• Staff enthusiasm for the e-learning technology.

In light of the three points highlighted above it is worth considering what web 2.0 technologies can offer. I shall constrain myself to the use of just one web 2.0 technology which is worth exploring as a significant complimentary or maybe alternative approach to the Blackboard VLE approach and that is a wiki.

For staff they are relatively easy to use and learn how to use, they are for group collaboration either via editable web pages or discussion boards. All group members can send messages to each other within the wiki. All group members can choose to be notified of any changes to pages or replies to discussion board posts straight to their email accounts. Pages can be tagged for easy reference, wiki sites can be very easily backed up in html or wiki text format.

Wiki’s can be used for learning activities, project management, project collaboration or as a course management tool. Wiki’s can allow staff to collaborate on projects and developing module material together. The technology is and it has the potential to be useful, it will be up to individuals and groups how they make best use of it.

To give a comparison example, it would be far easier and save so much time in posting an announcement and associated document in a wiki, rather than in the equivalent announcement function in blackboard, especially if the author has to re-edit the announcement or change the associated document.

Another important consideration is that web 2.0 technologies such as wiki’s and blog’s are now becoming commonplace out there in every day life. They are important life skills that students and staff should develop as these transferable skills will be of great benefit to them personally and to future organizations that they work for.

Although there are many web 2.o services freely available on the internet, possible concerns from an institutional point of view may be security and privacy and delivery of service. As an example if we take wiki services on the web these can be made private and secure, as well as having minimal downtime. If institutions are not satisfied with the offerings of companies that do offer wiki servers they can always use ‘MediaWiki’ software which is wiki server software and can be controlled by the institution on their own servers.

To conclude I believe that over the next year or two HE institutions should most definitely design a web 2.0 delivery strategy and adopt and promote it in parallel with any existing Blackboard VLE setup so that they are in position to take the correct fork in the road if required. Personally with a well thought out implementation and staff training plan I believe that the uptake of web 2.0 technologies will spread quicker than an Aussie bush fire and it might have to be if higher education institutions do not want to lose competitive advantage.

That old Chestnut - Blogging

Well here we are and a month has gone by since my last blog. I would love to have included a few more blogs before the end of January 2007 but the reality is that I had a 31 Jan deadline to meet, in relation to the design of a synchronous lesson on the use of wiki’s. So I have not had a wasted month, I have been through the rigour and thought processes of designing for the synchronous classroom and at the same time I have continued with developing my understanding of how wiki’s work/ don’t work both from a technical point of view and from a human point of view.

Ideally I would have wrote this blog entry in the middle of January, but when you are in the heart of battle, it is difficult to break off to give updates when you are on the brink of victory or near the edge of failure.

That said I am here now telling my story and I like the fact that my commitment to blogging draws me back and gets me thinking about the next subject i can usefully blog about. So for me this blogging escapade that I am embarked upon is useful to me in that it helps to:

• Consolidate my knowledge
• Recheck facts that I am not sure of
• Think though the implications of what I am writing and therefore try and understand ideas, concepts and facts that I am writing about.

This is all very well, fine and dandy. As my blogging is in the context of a long haul approach over a two year period and will culminate in a reflective essay on my blogging activities perhaps it is ok that I use my blog to aid my learning as laid out in the three points above.

Practically though on a 12 week module how can reflective blogging be used to benefit the learning of students. Unless some deep thought(learning) is part of the process, then the blog can just become a desperate attempt to get the appropriate number of words, links, images etc etc to meet the assessment criteria. Effective Blog learning strategies – this is a subject for another time....

Further to my recent activities on using wiki’s my next blog will look at the strengths of wiki’s and what teaching/ learning strategies will lead to effective use of a wiki.

Footnote1: As I have just finished writing this blog, it occurs that it is good to give readers an expectation of what to expect in the next blog- hopefully to heighten expectation so that readers will be keen to return and read the next installment.

Footnote 2: I only intended to write a couple of paragraphs just as an update, but it has rekindled my desire to return to the question of “what is the point of blogging?”

Making Sense of Learning

Theories of Learning
Precisely because learning is not a universally fixed or agreed concept, learning has been defined in many different ways. In trying to make sense of learning it seems appropriate and proper to establish at the outset that there are in fact different ways of learning, and that humans choose to learn different things in different ways.

The dominant focus on how people learn throughout the 20th century has been derived from psychology where the main theories of learning include behaviorism, cognitivism and constructivism. Other major theories of learning are based on a humanistic perspective rather than a psychological view. The humanistic theories are concerned with emotions and feelings and to my mind, can and do work in parallel with the three main psychological theories of learning.

Many other theories of learning have been proposed over the years which predominantly fall within the scope of these four main theories. In some cases due to the complex nature of learning, aspects of many sub theories may crossover the theoretical divisions.

A strong theme that has emerged in recent years has been the influence of social and cultural aspects to the learning process, so amongst the many sub theories of learning, social learning theories are very important in the learning process of humans.

The social learning theory of Bandura emphasizes the importance of observing and modeling the behaviors, attitudes, and emotional reactions of others(Kearsley 2003)

Brian Science is a study of how physically the brain functions and I think it helps inform the debate on how people learn.

So what are you doing when you are learning? What is the result of the learning process?
Once again with this complex business of learning there are no easy answers. I venture to suggest that it would be fair to say that depending on your viewpoint and/ or what you are learning you will be acquiring or creating knowledge. In discussing Driscoll’s (2000) definition of learning Siemens (2005) states that learning as viewed by the three main theories results in a “lasting changed state (emotional, mental, physiological (i.e. skills) brought about as a result of experiences and interactions with content or other people.

Siemens (2005) highlights that all three major psychological learning theories i.e. Behaviorism, Cognivitism and Constructivism hold the notion that “knowledge is an objective (or a state) that is attainable (if not already innate) through either reasoning or experiences.

After reading the Siemens (2005) article, the key points for me in differentiating between the different theories of learning was the observation that
• Behaviorism and Cognivitism view knowledge as external to the learner and the learning process as the act of internalizing knowledge.
• Constructivism suggests that learners create knowledge as they attempt to understand their experiences (Driscoll 2000 in Siemens (2005))

Further to the points above:
• The essence of behaviorism can be captured in three assumptions about learning:
o Observable behavior is more important than understanding internal activities.
o Behavior should be focused on simple elements: specific stimuli and responses.
o Learning is about behavior change. (Gredler 2001 in Siemens (2005))
• In cognitivism, knowledge is viewed as symbolic mental constructs in the learner's mind, and the learning process is the means by which these symbolic representations are committed to memory. (Buell in Siemens (2005)))
• Constructivism assumes that learners are not empty vessels to be filled with knowledge. Instead, learners are actively attempting to create meaning. Siemens (2005))
• Humanists, give primacy to the study of human needs and interests. A central assumption is that human beings behave out of intentionality and values. Huitt (2001)
Theories of learning can be described as explanations and descriptions of how people learn. Terry Mayes and Sara de Freitas (2004) offer the following definition

Theories of learning provide empirically-based accounts of the variables which influence the learning process, and provide explanations of the ways in which that influence occurs
What is apparent from reading the literature is that people can learn in a variety of different ways and are influenced by a number of factors. When it comes to learning material for students, awareness of the different learning theories combined with the learning objectives is essential in guiding a teacher in designing appropriate material for the subject and the objective to be learned.

Models of Learning
One of the most infuriating aspects of reading though the literature is trying to establish a clear distinction between a theory of learning and a model of learning. The difficulty lies in the fact that the word “Model” can be used to try and explain how exactly a learning theory works in a descriptive way i.e. modeling way. “Model” can also be used in a prescriptive way to suggest the best approach to take to enhance learning. In order for me to make sense of this contradiction I take the following views:
1. A theory of learning is a description of how people learn.
2. A model of learning is a prescriptive method (can be tightly or loosely prescribed) on how learning should best occur.
3. Models of learning will draw on various theories of learning and give teachers a framework in which to devise teaching strategies to ensure the maximum opportunity for student learning.
4. Models of learning are really models of teaching (see Teaching/ Learning Models)
5. Models of Learning/ Teaching will guide the Instructional Design activities developed for a program of study.

Embrace web 2.0 technology or die - that's an order!

It seems a no brainer to me that higher educational establishments offering distance learning courses should embrace web 2.0 technologies quickly otherwise their credibility is an institute of repute will quite frankly be tarnished. Relying on subject expertise will not be enough, the online delivery and communication techniques used will sort out the winners from the losers

It would seem that a lot of higher education institutions may think that by providing a VLE such as Blackboard they have done their bit for distance and e-learning and that is the end of the matter. Many institutions even at this stage may not even be aware of the growing influence of web 2.0 technologies and will bumble along quite merrily, as their customer (student) base dwindles away.

If I can make some sort of an analogy between institutions (and it may not be the best, but hopefully you will get the point) that embrace web 2.0 technologies and those that don’t, it would be like comparing an institution that currently asks for all essays to be handwritten instead of an institution that accepts word processed essays. Most students would find this unacceptable, irritating and a sign of an organization not up with the times. This will probably be the case with web 2.0 technologies and the benefits they offer in communication, community building, learning and teaching 5 years from now.

The only conceivable argument I can see for not embracing web 2.0 technologies are considerations of privacy and security of data. If there are good educational and learning reasons for using web 2.0 technology then a way needs to be found to overcome privacy and security of data issues, which I am sure, can easily be found if the desire is there.

Quite bold statements from a mere novice in the field, however after reading various advocates testimony, briefly reviewing some web 2.o technologies the vibe just feels right. My proviso being that web 2.0 technologies give you the platform to do some very interesting things, but you’ve got to know your technology and use it well.

web 2.0 Adventures

My recent adventures into web 2.0 land that have ignited my fire are the web application ‘basecamp’, which uses wiki technology (only it just does not tell you) for the purpose of project management and it makes it feel so damn easy. I am sure higher education can learn a lot from the ease of use of this product and it seems ideal for use as a course management system. I shall investigate further.

The second vitally important element of the whole web 2.0 phenomenon is the XML feed technology e.g. RSS or Atom and the ability to subscribe to blogs. I’m afraid I’m a busy man, hey maybe I’m a bit lazy – I want the action to come to me. I cannot always remember where all the action is or will be so I want notification by the killer internet application email or I want all the action sucked into my central website base.

So this leads to the beauty of subscription where your favourite blogs can be emailed directly to you, using a subscription service such as feedblitz or alternatively, use a service such as bloglines where all your favourite blogs are brought together at a central website.

Wake up there could be a revolution going on.

Adults learn different to kids! What a load of androgogy

Previously I’ve had a look at models of learning that emanate from psychology; lately I have looked at models from adult education. This blog is a summary of information contained in the Tusting and Barton (2003) book ‘Models of Adult Learning: a literature review’.

Many parts of this blog are quoted verbatim from the book, this is not to pass the work off as my own, but so that I have an accurate overview of this literature review of adult education. [As a side note I have found blogging a useful tool in recapping, reflecting on and summarizing the reading that I have done]

The most famous model of adult learning will be Knowles (1973) model of learning called andragogy. A very brief summary is that adult learners are driven by an internal motivation, they bring their own experience to the table of learning and they need to know why the need to learn something as opposed to kids which are told what to learn by their teacher and they have got no choice to learn, it’s compulsory. Its funny that “YOU WILL LEARN!” yes please, can I have some more sir.

Critics of the theory include Brookfield (1994) who suggest it is more of an ideal state for adult learners to be in rather than a descriptive model of how adults learn and Hanson (1996) argues that there is little real evidence of an absolute difference between adults and children in terms of learning.

Knowles draws on humanistic psychology for his model. Humanistic psychology takes human potential and desire for growth as a basic assumption. Maslow (1970) and Rogers (1994) are out of this school and, both assume that people have an intrinsic drive towards growth and self direction.

Important elements of androgogy that have been developed in great depth in the adult education field include:

• Self directed Learning
• Learning how to learn
• Informal learning
• Reflective and experiential learning
• Transformative learning

Self directed learning
Has been represented in a descriptive way i.e that it is a characteristic of adult learners and in a prescriptive way i.e. that this a mode of study that adult learners should pursue. Brockett and Hiemstra (1991) claim that there seems to be a link between self direction and positive self concept, and more tentatively between self direction and life satisfaction. They suggest that strategies to enhance self-direction include:
• Facilitating critical reflection through reading and writing.
• Promoting Rational thinking.
• Developing people’s helping skills.

Candy (1991) demonstrates how the concept of self direction is actually used to gloss over at least four distinct concepts. Two are activities
• Autodidaxy (the independent pursuit of learning outside of formal institutional structures)
• Learner control as a way of organizing instruction

And two are personal attributes or characteristics:
• Autonomy as a personal quality or attribute
• Self Management in learning, the manifestation of independence of mind or purpose in learning situations.

Candy claims that there are important constraints on the extent to which people can or should strive to be self directed, especially when learning formal or technical bodies of knowledge, as opposed to acquiring greater self-knowledge.

Learning how to learn
Through the study of self directed learning, the idea has developed that adults can and should become aware of their own learning processes and how to manage them.

Smith (1983) Suggests there are four distinctive characteristics of adult learners.

1. They have a different orientation to learning than children.
2. They have an accumulation of experience that forms the basis for new learning.
3. Different developmental tasks await adults at different points in their lives and education is sought during periods of transition.
4. Their learning is often characterized by anxiety and ambivalence related to negative experiences of early schooling, the contradictory status of being both an autonomous adult and a dependent student, and other similar emotional challenges.

Smith’S distinctive contribution to this field of study is that he is suggesting that by learning how to learn, adults can learn how to become autonomous learners.

Informal Learning
In their book “Models of adult learning: a literature review” Tusting and Barton (2003) identify that there is some overlap between the literature on self directed learning and that on ‘informal learning’. Informal Learning has been described in a variety of ways including:
• To describe the way adults learn outside formal provision.
• To refer to unplanned or unpremeditated learning.
• Learning which has not been formally structured.
• To refer to provision in the community as opposed to that which is provided by formal educational institutions.
• To refer to any non-accredited provision.

Coffield (2000) underlines the importance of informal learning in the formation of knowledge and skills, describing formal learning in institutions as being merely ‘the tip of the iceberg’. Through his research document ‘The learning society: knowledge and skills for employment’ he found that informal learning is often necessary to do the job, while formal learning is often dispensable.

McGivney(1999) has found that community based informal learning has wide ranging benefits in widening participation in signposting adults to formal learning and improving personal and social skills. Foley (1999) also shows that various forms of incidental learning take place when people become involved in social struggle and political activity.

Reflective and Experiential Learning
Dewey’s (1933) work ‘How we think’ underlies much of the literature on reflective and experiential learning. He identified five stages of thinking involved in the process of moving from an initial state of confusion to a final cleared-up, unified, resolved situation. These are:
1. Suggestions.
2. An intellectualization of the difficulty that has been felt into a problem to be solved, a question for which the answer may be sought.
3. The use of one suggestion after another as a leading idea.
4. The mental elaboration of the idea or supposition as an idea or supposition.
5. Testing the idea by overt or imaginative action.

The thinking is not ordered and simple as in the list above, but he describes the process of reflective thinking as dynamic and messy, and that it is having the clear gradually emerge from the unclear that concepts and ideas are formed and that learning happens.

In more recent years David Kolb is the name most closely associated with reflective and experiential learning. Kolb’s cycle of learning requires the resolution of four conflicting modes of adaptation to the world.
• Concrete Experience (CE)
• Reflective Observation (RO)
• Abstract Conceptualisation (AC)
• Active Experimentation (AE)

According to Kolb (1984) “Learning is the process whereby knowledge is created through the transformation of experience. Smith (1983) states that Kolb’s work on learning styles underpins a great deal of contemporary ‘learning to learn’ practice.

Here is the rub with learning styles, Kolb believes that the ‘ideal learner’ far from favouring one particular learning style would develop a balance between all four stages of the cycle and therefore would master all four learning styles as appropriate. This goes slightly against the grain of the opinion that says ‘find a student’s learning style and cater for that style’.

Others who have developed ideas around reflective and experiential experience include Jarvis (1987) whose model of adult learning in social context is based on the idea that learning becomes possible whenever there is a disjuncture between biography and experience. Jarvis believes there are 9 potential responses to this disjuncture:
• 3 non-learning responses.
• 3 non-reflective responses.
• 3 reflective learning responses.

Tennant and Pogson (1995) examined various ways in which experience has been incorporated into learning, the most interesting for me was their view on how Rogers’ and Maslow’s theories stress the emotionally laden nature of the relationship between experience and learning. They point out that in order for learning to occur, the learner must in some way go beyond experience alone. Instead, experience must be mediated, reconstructed or transformed in some way. They therefore ask the crucial question, how and under what conditions can people reconstruct their experience and thereby learn from it. They identify 4 approaches to experiential learning:
• Linking material to prior experiences.
• Relating learning to current experiences.
• Creating new experiences from which to learn, through techniques such as role play and simulation.
• Learning from lived experience through talking about, analyzing, and acting on the implications of the experience.

Transformative Learning
Tusting and Barton (2003) state that critical reflection is central to those models that focus particularly on the transformative potential of adult learning. These theories see learning as primarily as a means of personal or social transformation.

Mezirow is the theorist most closely associated with personal transformational models of learning through his model ‘perspective transformation’. He suggests reflection has three primary purposes:
• To guide action.
• Give coherence to the unfamiliar.
• Reassess the justification of what is already known.

The third purpose is the one that is central to critical reflection and works to examine and potentially transform the structure of assumptions with which we make meaning. This structure of assumptions is acquired through socialization processes, and Mezirow suggests that in adulthood we reassess the assumptions that we acquired during our formative childhood years, often in response to disorienting dilemmas that challenge the notions of reality we had previously taken for granted.

Clark and Wilson (1991) note that Mezirow’s work has been criticized for being too focused on the individual and for not taking into account the social and cultural factors that govern whether transformation can be possible.

An alternative model of transformation is expressed by Paulo Friere (1972), who sees learning as central to transformation at the social level. in his work ‘pedagogy of the oppressed’

Frierian methodologies start from people’s lived experience, eliciting and working with words and concepts that are already familiar to people in their everyday lives. The teacher is expected to transcend the divide between themselves and the students by committing ‘class suicide’ as an educator and being reborn (through an ‘Easter experience’) as a joint educator/educatee with the students. (Taylor 1993)

Friere’s work has been criticized on a variety of front’s. His writing can be dense and unclear and verges in many places on the mystical (see Taylor 1993). Tusting and Barton (2003) note however, that his influence on the development of popular education, literacy education and adult education has been widespread and profound and he is one of the principal inspirations behind the radical and critical tradition of adult education.

An article of interest in relation to transformative learning is the following: Shaheena Abbas ‘Transformative’ models for learning, teaching and Academic Professional Development – A ‘Self-ish’ Approach

Hey Wiki! Your so fine you blow my mind. Hey Wiki

After setting up a very basic wiki, I have just started to take a look at the use of wiki's in education. My findings are summarized below and are based on reading the following 4 web documents and listening to a skypecast (link below).

1. Naomi Augar, Ruth Raitman and Wanlei (Nov 2004) Zhou “Teaching and learning online with wikis” http://www.ascilite.org.au/conferences/perth04/procs/augar.html

After reading educators feedback on these various websites, seeing how wiki's are currently being employed on the web and listening to an interesting skypecast led by Steve Haregedon it does seem that a wiki in education does indeed have the capability to metaphorically blow your mind. It would appear to be a very powerful tool to engage the students and produce good quality, useful content much more quickly than a student working alone.

Through my reading and skypecast listening I know have a basic understanding of the point of a wiki. With a little more knowledge about the features, functionality and role of wiki’s in education I intend to setup new wikis and collaborate on existing wiki’s to further improve my understanding of the educational uses of a wiki.

Differences between Wikis and Blogs
Before I summarize my findings I’d like to pick up on a couple of interesting points made by Vicki Davis (2006) on the difference between wiki’s and blogs. According to Vicki she explains that the way she looks at it:

1. A wiki is more concerned with facts and a blog is more about opinions and
2. It's easier to contribute to a wiki rather than a blog.

Although I don’t think this will or can be strictly applied, these are two interesting points which may be a nice neat starting point in distinguishing between the uses of the two types of technology.

The Wiki
A wiki is basically a very simple and easy to edit web page. It is designed for group collaboration. Users can either read the content of or add content to a wiki document page.

Vicki Davies (2006) a teacher at Westwood Schools in America and a strong advocator of wikis predicts that wiki’s will become the hub of education in the future. Vicky sees wiki’s as the toolbelt that holds all her technology learning tools together, the central focus of what she teaches. Joe Grohens (2006) supports this view in that he uses wikis as a complete course management system.

Augar, Raitman and Zhou (2004) describe wikis has having 2 different writing modes, or styles of usage:

1. Document mode, where writers create collaborative documents written in the third person and
2. Thread mode, where contributors carry out discussions in the wiki environment by posting signed messages. Others respond leaving the original message in tact and eventually a group of threaded messages evolve.

Pages of wiki can also be described as having two states a ‘read’ state and an ‘edit’ state. To edit a page users click an edit button. Editing a page on most wiki websites is made easy by providers who provide editing toolbars. If no editing toolbar is available then users need to understand wiki language syntax to edit a page (although not too difficult, the edit toolbar makes it a lot simpler for users)


Wiki Features and Functions
The main features and functions that you will find in a wiki include:

1. Authentication – By participants logging into a wiki any addition’s to content can be authenticated providing accountability in terms of who said what and when. [with authentication participants may also have use of a signature tool to move into edit mode automatically inserts the participants wiki username. The signature tool is often hyperlinked to a personal user page which helps students to build an online identity in the wiki environment.
2. Backup and Retrieval of earlier wiki entries.
3. Tracking – Usually in the form of a recent changes page where student participation can be assessed.
4. Notifications by email of any recent updates so that users can check on any new material that is of interest to them and change information if incorrect.
5. Uploading of images and other media

Strengths of Wikis
The basic strengths of a wiki are:

1. Simple and easy to use
2. Easy to learn how to use.
3. Excellent for collaboration and collaboration over time
4. Easy to share.
5. Simple technology – only need internet access and a web browser.
6. Ability to compare two different versions of a wiki

Student Benefits
For students the benefits of a wiki include:

1. It is a student centered environment, students can be involved in the structure and the content.
2. Everyone in a class can access the same version of the work.
3. Previous versions of the work can be recovered
4. Easy to correct mistakes
5. Because it is simple and easy to use, barriers to contributing are removed.
6. Accessible from any computer allowing students to work on assignments at any time.
7. Group work skills can be improved.
8. Steady incremental improvement in both the organization and the content of a document.
9. Social interaction is enhanced. A sense of community can be built up.
10. Information easily disseminated.
11. Information easily stored.
12. Collaborative production of documents. This can build a body of knowledge wider and quicker than an individual. The social and technological interaction can enhance learning. Steve Haragedon (2006) believes that “collaborative efforts are generally better than individual”.

Teacher Benefits
For teachers benefits include:

1. Easy place to post assignment instructions.
2. Easy place organize course material.
3. Wiki’s can be password protected
4. Better than discussion boards, easier to administer according to Joe Grohens
5. Easy for students to submit there work
6. Keeps a log of revisions of student work

Educational Uses
The educational uses of a wiki will be wide and varied some uses that have come to light during my reading include:

1. Summary of Lessons
2. Collaboration of notes i.e. sets of documents that reflect shared knowledge.
3. Dissemination of important information
4. Build up core content and Topic base e.g. creating a book
5. Pre Class planning e.g. Ask students ahead of time what they want to study and shape the content around that.
6. Students can supply feedback to each other
7. frequent revisions and drafts due to the inherent simplicity of wiki technology.
8. Exchange of ideas.
9. Facilitates group interaction. E.g see Auger, Raitman and Zhou’s example idea of an introductory icebreaker.
10. Individual Assessment projects?

Usage Guidelines
An important aspect not to be overlooked is a clear set of usage guidelines, Augar, Raitman and Zhou (2004) advise from their study that these should be short, simple and written in a positive tone. There guidelines “encouraged users to be considerate of others and be active and friendly in their wiki posts”.

Issues
Despite all the positive sounding noises, Scagnoli points out a number of challenges and issues that need addressing. These include plagiarism/ copyright issues, monitoring can be difficult and problems of outside editors should a public wiki site be used.

Conclusion
Hopefully this blog although not capturing everything relevant, touches upon the main aspects of a wiki from an educational point of view. My focus now will be to work and participate in wikis and to identify specific, practical exercises that enhance student learning.
