The reusability paradox – WTF?

WTF?

The reusability paradox.  How can reusability be bad?

When first presented with this concept last year, I must admit I really did struggle with it.  As a techhie, every fibre of my being compels me to focus on reuse.  Hence, the paradox.  After some weeks of struggling with the reusability paradox, it did start to make some sense, emphasis on some’.

I have recently revisited this concept, both in discussion with my (to be) PhD supervisor, but also in my day-to-day work as an Educational Developer/Lecturer/Educational Technologist.  My revisit has prompted this blog post as a way of recording some connections I have made to real-world examples of this phenomenon, and how this impacts my thinking about technology (re)use.  This thinking is far from crystalised.

David Wiley explains the reusability paradox in the context of reusable learning objects, and more broadly, the open content movement.  When this concept was initially presented to me, it was already positioned in terms of technology.  I find it easier to start with the original context in learning design.

What is the reusability paradox?

David explains it quite succinctly as:

A content module’s stand-alone pedagogical effectiveness is inversely proportional to its reusability.

He explains that the more contextualised a learning object is made, the more meaningful it becomes to that context.  However, it also means the learning object becomes less reusable to other contexts.  We have a trade-off situation – effectiveness (in learning) vs. efficiency (in scalability). David concludes:

It turns out that reusability and pedagogical effectiveness are completely orthogonal to each other. Therefore, pedagogical effectiveness and potential for reuse are completely at odds with one another, unless the end user is permitted to edit the learning object. The application of an open license to a learning object resolves the paradox.

I don’t think an open licence alone will resolve the paradox, but that is a discussion for another post.

The reusability paradox in the wild

So enough of abstract concepts – how does the reusability paradox play out in the wild and in other ways besides learning objects?

i-see-dead-people
“I see dead people the reusability paradox.”

I often see the reusability paradox when working with lecturers – conceptually the same as David Wiley explains, but at a higher level.  My particular experience relates to the contention of reusing units of study between different awards/degrees.  This is pretty typical in the STEM areas – in my institution we refer to them as service courses (units).  I work with a science school, and a key foundation unit of study taught from the school is anatomy and physiology.  There would be a dozen or more degrees that require students to have a sound knowledge in this area.

Conventional management wisdom seeks to reuse anatomy and physiology units for health related-degrees.  This is efficient use of resources, right?  And “why re-invent the wheel?”

But before I explore those questions, let’s first take a step back for a moment.

The key criteria for reuse is applicability to other contexts.  If there is sufficient overlap or congruence with another context, then a reusability factor could be considered high, thus worthy of reuse.  Learning is very contextual, particularly when you factor, as David does, the underpinning of constructivist learning theory.  Learners construct new knowledge, upon their own existing knowledge.  This is very individualised, and based on each learner’s past experiences, and ways of thinking.

Learning designers have some tricks to help deal with such diversity, such as researching your cohort, conducting a needs analysis, and ultimately categorising learners and focusing on the majority.  Clearly, this is flawed – but this is how massification of education works.  For instance, if you are preparing a unit of study for nursing students, then you can make some reasonable assumptions about those students motivations (i.e. they want to become a nurse); their prior formal learning (i.e. previous units studied within a structured nursing curriculum); and even down to smaller groups such as pathways to study (i.e. were they enrolled nurses – ENs or school-leavers). These assumptions of course aren’t always correct.  Nevertheless, the key point is that this unit of study is reused by all nursing students studying for the Bachelor of Nursing degree.  A more or less reasonable trade-off between effectiveness and efficiency.

So let’s return to the example of an anatomy and physiology unit of study.  In this instance, we see different discipline areas, albeit health related, attempting to reuse a unit of study.  Despite all being health related, a paramedic student’s needs aren’t the same as physiotherapy students’, or medical science students’.  And while some disciplines hail from within the same school, others disciplines are situated elsewhere within the organisational structure.  Now, consider the diversity of the cohort.

So to cope with this type of diversity, I typically see three approaches:

  1. Make the unit of study as abstract (decontextualised) as possible making no assumptions about learners or their backgrounds, and “teach the facts”.
  2. Design the unit to cope with the highest represented context (i.e. the discipline with the most students).
  3. Design the unit of study to address multiple contexts, in an attempt to make it meaningful to multiple disciplinary groups.

In other words, make it meaningful for no-one; make it meaningful to the biggest group, and nobody else; or, try to make it meaningful for everyone.

Approach 1 is obviously ineffective, especially considering constructivist thinking.  You end up with students asking “why do I need to know this?”, or “that course was so dry and boring.”

Approach 2 while not quite as flawed as approach 1, can be less than ideal.  Particularly when the highest represented group is small compared to the entire group.  In such cases, the other groups feel marginalised, “I want to be a Paramed, not a Physiotherapist.”

Approach 3 can also ineffective because you can end up with a study unit that is incredibly complex.  This group of students does this, that group does that.  As the lecturer, you have to manage the mixture.  The students too can become confused about requirements. You can also run into “equity” type policy constraints, such as “all students must do the same assessments.”  This is an important point.  If you end up with such complexity, you really have to ask the question, “why not just have separate units of study?”

But solving this challenge isn’t the focus of my blog post.

The Reusability Paradox as it Applies to Education Technology

So does the concept translate to technology?  Yes it does!  And similar issues arise as a result.

Recall the three approaches I see people use to deal with the challenges of reuse for multiple contexts?

  1. Make abstract
  2. Contextualise for the largest group
  3. Contextualise in multiple ways for multiple groups

Let’s consider Approach 1

David Wiley says of the reusability paradox:

The purpose of learning objects and their reality seem to be at odds with one another. On the one hand, the smaller designers create their learning objects, the more reusable those objects will be. On the other hand, the smaller learning objects are, the more likely it is that only humans will be able to assemble them into meaningful instruction.

I think this statement has some “translatability” to an education technology context as:

On the one hand, the smaller developers create their learning technology tools (e.g. programming libraries rather than complete systems), the more reusable those tools will be. On the other hand, the smaller learning technology tools are, the more likely it is that only developers (and not designers) will be able to assemble them into functional learning technologies.

David Wiley also says:

To make learning objects maximally reusable, learning objects should contain as little context as possible.

To remove context is to make something more abstract – to take away intrinsic meaning or specific function.  Indeed this makes things more reusable, it also requires re-contextualisation.  In the context of technology, abstraction leads to dependence on the developer.

Let’s skip to approach 3.  With this approach, we end up with technology that attempts to do everything for everyone.  These technologies become so complicated to use, that people simply don’t use them.  My favourite example of approach 3 is the Moodle Workshop activity which is a “powerful peer assessment activity”.  I consider myself to have a reasonable grasp of technology, and yet after 45 minutes of tinkering with the workshop activity in Moodle, I gave up.  I have only seen 1 person at my institution use it.  It has so many options, too many options, because it tries to account for all the different ways one might attempt to embed peer assessment into their course.

So what about approach 2?  We reuse a learning technology without change – meaning it is focused on the majority of requirements (however that might be determined).  This is typical of COTS (commercial off the shelf) solutions.  This inevitably leads to functional gaps – “the system does this, but I want to do that.”  If the gap is substantial, it can lead to workarounds.

Does technology need to be reusable?

This is where I struggled last year with the reusability paradox.  If you can’t reuse a technology, then isn’t that a serious limitation?  Management are constantly looking to replicate successes – “This worked so well, so how can we use this in other areas?”

When I am creating/adapting/augmenting technology for others, I have to demonstrate “bang for buck” in terms of my time invested.  Does what I create, at least have to pay for itself in affordances?  I normally look for economies of scale, and the obvious way is through reuse – it is usable by X number of people.  Management/decision-makers get this – easy. However, technology can offer other economies.  For instance, depending on the technology, it may instead allow a specific group of people to do something much better, quicker, cheaper, or if its very innovative, something they couldn’t do before.  But that something might be very specific, so specific that it isn’t very reusable, and limited to a small audience.  Yet, if it still yields a net gain, is that bad?

What if a technology is so specific, it’s designed for just one person – yourself?

Workarounds

At some stage in our lives, we have all had to engage with some form of workaround to get from A to B.  Not just in terms of technology but life in general.

If you create a workaround, does it need to be reusable?  Perhaps not.  But what if you want it to be?  How can you go about it?

This is where my time (and thinking) ends for now.

 

Managing (universities) in an age of complexity

This blog post relates to my study of CCK11.

I have just read an article by Dr Jean Boulton titled Managing in an Age of Complexity.  I really enjoyed reading this article.  I think the main reason was that it resonated with me and my context working for an Australian University.

The key message of Boulton’s article is that decision-making is founded on the assumption of certainty.  But is this assumption sound?  Do we live in a world of certainty and determinism.  Is there a simple cause and effect relationship to our decision-making?  Boulton postulates that there are two reasons for our assumption of certainty for decision-making.  The first is psychological.  Humans desire certainty and control.  On reflection, this stands to reason.  There would be few people that would enjoy a lack of structure, order or control of one’s circumstances.  The second reason is founded in pattern entrainment. Let me explain.  The philosopher Aristotle postulated “that to be rational is to be superior” (Boulton).   In the 17th century, Isaac Newton demonstrated the physics underpinning the movement of the planets around the sun to be founded by 3 simple laws.  A mechanical system.  Apply rationality, and the success of Isaac Newton’s concept of mechanical systems became the foundation of all our thinking about systems and decision-making.  So why is this pattern entrainment?  David Jones describes pattern entrainment as follows.

Dave Snowden has given me the term “pattern entrainment” for the tendency for peoples conceptions to be limited, entrained based on the successes of the past. What has worked for us in the past, becomes the source of all our thinking about the future.

So society has applied the successful theories of Isaac Newton around mechanical systems as a foundation of decision-making in all systems.  However, are all systems mechanical?

Boulton lists the following attributes of a mechanical system:

  • Does not interact with the outside world
  • Simple interactions between parts
  • Parts identical within the same class
  • Parts and interactions cannot change

These attributes certainly do not apply to the higher education system.  In fact, it would contradict every one of those attributes.  So what type of system is higher education?  Boulton introduces the concept of a complex system.  In doing so, she introduces the research of Russian-born physicist Ilya Prigogine where he developed a theory known as non-equilibrium thermodynamics.  His theory “recognises that most systems in the real world are … constantly changing due to their exchange of energy with the environment.  These types of systems came to be called complex systems.” (Boulton)

Attributes of a complex system are described by Boulton as:

  • Unpredictable; things in general do not go to plan
  • Non-average; small events can have big effects
  • Without diversity, there is no learning
  • Structures that are interconnected are more adaptable to changing circumstances
  • Systems may self-organise at tipping points
  • New characteristics sometimes emerge in a way that can neither be predicted nor planned

This seems a much better fit for Higher Education to me.  So how do we manage a complex system?  I believe Boulton suggests that we embrace the uncertainty and develop strategies to cope with it.  Consider unexpected events as opportunities rather than threats.  To do this, she suggests that we focus on interconnections, networks, cross-functional processes, informality, relationships and encouraging diversity within the system.

Other suggestions for approaches to managing complex systems include:

  • Scanning and fore-sighting
  • Handling complexity
  • Weaving a vision
  • Using judgement
  • Empowering others
  • Collaborating
  • Ability to adapt to changing circumstances and seize opportunities

A quote that resonates well with my context in higher education:

Everywhere around us organisations and individuals are expected to take measurements and take decisions based on their implied certainty. Schools, teachers and pupils are subject to more and more measurements; the content of courses and the way to teach them is increasingly set out in rigid fashion.

I am seeing more and more of this happening at my institution often in the name of quality.  And what of it?  Boulton continues with a quote from Mintzberg:

And, in one sense, what is wrong with all this? Of course, nothing is wrong with it – if it works, if it really leads to better management decisions, and better outcomes. But does it? Mintzberg, the well-known and respected guru
on strategy and organisations, has this to say:
“We’ve become prisoners of measurement; audits, league tables, targets. It just destroys creativity.
I am not opposed to measuring things that can be measured
– I’m opposed to letting those things drive everything else out. It has some destructive effects in business, but in education and healthcare it is absolutely devastating.
What would happen if we started from the premise that we can’t measure what matters and go from there? Then, instead of measurement, we’d have to use something very scary; it’s called judgement”.

As Mintzberg puts it, it destroys creativity.  I am seeing more and more of this too.

Time’s up for writing this blog post.  This article was a great read, and putting into my own words Boulton’s message has been worthwhile.  I hope this summary proves useful to someone else.

PLE/PLN and the commodified education industry

This blog post relates to my study of CCK11.

Sui Fai John Mak had this to say in response to a previous blog post of mine on PLE/PLNs.

So would the education system affect how and why PLE or PLN would be applied?  How about the learners learning under such education system?  What are the implications?

Very pertinent questions indeed.  I really do like the concept of learner centred and owned environments and networks.  However, the culture of higher education, at least in Australia does not align well with these ideals.  This I believe is as a result of commodification of the education industry.  More and more, Australian Universities are pitted against one another competing for students.  The more students you have, the more money you get.  This is in a country where almost all Universities are government owned and run.  I think there are maybe 2 or 3 Universities in Australia that are privately owned.  While in contrast to the United States for example where many Universities are not Government owned and run, education is increasingly a customer-driven industry, and product to be traded.

There is support for the idea that people learn better by collaborating rather than competing.  While not an absolute and dependent on context, it is a reasonable assertion within the higher education context.  With universities competing, there is greater focus on “commercial in-confidence” than on openness.  The problem is that in competing for students, focus of institutions can stray from being “about the students and their learning journey and quality” to the less noble “how can we recruit and retain as many students as possible?”.

Sadly, I don’t see the PLE/PLN concept getting very far, at least in the current climate.  I hope I am wrong. 🙂

PLEs: for the connectives or collectives?

This blog post relates to my study of CCK11.

The concept of the personal learning environment is founded on the idea of learning control and autonomy.  It is a personal environment for the learner – learner centric.

Yet practically, formal education is a controlled environment.  We live in a world with tighter and tighter controls on learning.  The Australian Government for example has been pushing in recent years for a national curriculum for K-12, replacing the disparate state-based curriculum currently in place in our 6 states and 2 territories.  Tertiary education too in many disciplines requires accreditation with professional bodies, again requiring adherence to standardised requirements for students.  Students must develop specific skills and attitudes as a part of a program’s curriculum for the curriculum to be certified and for students to be acknowledged in the field in which they have studied.

I’m not suggesting this is all bad, but it is at odds (at least on some levels) with the ideals of personal learning environments – the learner having control of their own learning.  In fact, I have wrestled with a similar dilemma previously in my assessment of ePortfolios for higher education where there are competing goals.

This dichotomy of autonomy vs. control relates to week 5 discussions around networks and groups.  In particular, the idea of connectives, and collectives.  You could argue that collectives (accreditation/prof bodies & governments) have specific goals for students.  They want to ensure consistent outcomes for graduates.  This can be at odds with connectives – students who have their own goals for their learning.  Where is the happy medium on the spectrum?  If Europe can adopt a common currency, then perhaps education can too? 🙂

PLEs and PLNs

This blog post relates to my study of CCK11.

What are the downsides? (http://net.educause.edu/ir/library/pdf/ELI7049.pdf)

As a learning platform that is by definition always evolving, a PLE requires students to engage in ongoing decision making to maintain, organise, and grow their learning environments.  The process of self-directed learning requires a degree of self-awareness, and it must be given time to mature.  Some students, however, may have never taken the time to think about their own metacognition or to reflect on how they learn best.  These less experienced students may not be ready for the responsibility that comes with building and managing a PLE.

Interesting, and a serious downside indeed.  Managing one’s own learning is not a trivial task – it’s a big responsibility.  Is it reasonable to expect that everyone be able to manage their own learning to this level of detail?  A noble vision, but is it practical or reasonably attainable, or simply a fairy-tale view of education?  Let me explain my context, and why I believe this downside is understated, and why I don’t believe this ideal is realistic in a global way – a panacea.

I’m from Australia.  Higher education in Australia is partly funded by the Australian Government.  Students pay a portion of the tuition fees, and can defer their payments until after they obtain a job.  In the meantime, the tuition debt only grows inline with the CPI.  In other words, Australian tertiary students do not pay interest on their loans, and only pay a proportion of the overall costs which are subsidised by the Government.  Tertiary education in Australia is very accessible. Given this accessibility, and the diminished cost to the individual, there is greater diversity in the motivations of students in Australian higher-ed.  The fall-out from failure isn’t as significant as other countries where the individual bears the burden of the full costs of their education.  Don’t get me wrong, I think we have an outstanding system in place, that provides equitable access to higher education.  You don’t have to be wealthy to have a go in Australia.

I’m getting to the point… promise. 🙂  Take the following quote from a blog post I wrote some time ago, where I was reflecting on the book Teaching for Quality Learning at University, written by John Biggs.

Biggs introduces two student characters that represent two distinct groups of students that comprise a class.  They are also featured in a short film titled Teaching Teaching & Understanding Understanding.  Their names are Susan and Robert.  Susan is the typical academically minded student.  She comes to classes prepared, including pre-reading class materials, reflection on this material, and questions about her understanding of it.  Then there is Robert.  Robert is characterised as a student who is there out of necessity rather than desire.  He only wants to achieve sufficiently to be able to get a good job.  The course he is doing may not have been his first choice.  He comes to class with little preparation or prior reflection.  He hopes to rote learn and memorise to be able to pass his course.  These two characters form the cornerstone of his theories into the effectiveness of active versus passive learning.

Not all students are motivated in the same way when it comes to managing their learning.  Robert is not so interested in managing his learning – its about hoops to jump through to get his piece of paper (qualification).  Constructive Alignment, a theory by John Biggs suggests amongst other things that learning must be active – it is all about what the students do.  This in my opinion has merit, but like all theories, is contextual.  That aside, Biggs believes that you can create learning situations that force students such as Robert to be more active learners. As John puts it in an epilogue to the Teaching Teaching & Understanding Understanding Video (Part 3):

Thus we see that alignment throughout the system is based on the relevant constructive student activity.  In our “apply” example, the intended learning outcome, the teaching/learning activities, and the assessment task are all focused on that single verb “apply”:  we have woven a constructive web from which students would find difficulty in escaping without learning.

However, this method of making it difficult for students to escape in my view can often lead to task corruption.  It astounds me what lengths students will go to to avoid doing something if their heart just isn’t in it.

When I reflect on my early teens as an undergraduate student, my level of maturity and my motivations at the time were not conducive to learning management.  I was more interested in drinking, girls, and having fun.  I’m not suggesting that all teenagers are this way, but I don’t believe I was unique either.  Only when I commenced my Master degree, in my mid-20s did I become mature enough to take on the responsibility of managing my own learning.  This is evident through my improved GPA. 🙂  At the time, the web 2.0 revolution had not yet hit mainstream and many of these ideas had not yet been conceived (Oh I’m getting old).

Some may be able to manage their learning using a PLE/PLN, and I see PLE/PLNs as but one way of student learning.  We must remember the crucial point that whatever we do, it must fit the context.  Forcing students to create their own PLE/PLN and be able to manage their learning through this personalised environment is thwart with danger.  Even if you spend the time developing students’ abilities to manage their own learning, doesn’t mean that they will actually do it.

Groups and Networks

This blog post relates to my study of CCK.

In the week 5 material for the course, I have watched a presentation by George Siemens relating to groups and networks.  I really enjoyed watching this presentation, as much of the content resonated with me and my context.  I am blogging some of the more fascinating concepts that George highlights in the presentation.

Connectives: autonomy of self (mosaic)

George talks about human nature.  While we like to be social and be part of things larger than ourselves, such as groups, networks and so on, we also have a desire to retain in part, our own sense of self.  To have some level of autonomy, and individualism, and recognition or ownership of our own contributions to the network.  When engaging with networks largely this way, George describes these people as connectives. George has used the analogy of a mosaic, which I like.  What comes to my mind is a patchwork quilt – connectives contributions aren’t always the same (different colours & textures), and don’t always neatly fit together (jaggered edges), yet you still have a whole (patchwork quilt – network).

In networks comprising of mostly connectives, there is greater diversity of views and ideas and greater autonomy.  The network is less integrated and co-ordinated.

Connectives retain a sense of sovereignty within the larger group.

Collectives: subsumption of self (melting pot)

As connectedness grows stronger, the diversity of views and ideas normalise into collective views and ideas, with a loss of autonomy, but become more co-ordinated and integrated.  Co-ordinated in the sense that there is common understanding, common goals and common views.

When engaging in networks in this way, you are known as collectives.

So following on from the patchwork quilt analogy of connectives, a collective is a quilt that is uniform in colour and texture.  Focusing on the colour, it is derived from the colours of each individual contributor, but unlike connective quilts (patchwork), collective quilts converge to the one shade.

Achievement of the complex

George talks about coercion to the norm in group environments.  Connectives who express different views or ideas from the norm of the group are pressured to assimilate to the group views.

This presents challenges in the achievement of complex tasks that require groups to work together.  There needs to be a level of trust, and some level of common understanding and agreed goals amongst the group.  But at the same time, it is important to fulfill the needs of human nature and retain some levels of autonomy and individualism.

I think an excellent example of this balance between connective and collective group engagement is the continent of Europe.  Europe is comprised of many different countries, all with their own cultures and attitudes and yet, Europe can also function as a whole through the European Union.  Take for example, the adoption of the Euro as a continental currency.  There was great benefit to the individual countries of Europe to have a common currency (global strength compared to $US and GBP).  However, if you take a look at the physical currency (ie coins and notes), they share the same size and shape, but the imprints are different – individual.

Innovation is deviation

This would be my favourite idea presented by George.  In a collective, where there are agreed views or ways of doing things, the suggestion of doing something different is often seen as a threat.  To innovate deviates from the norms of the group.  Yet innovation is a crucial part of any group – it is what keeps minds open, and possibilities possible. It also distinguishes individuals and groups from one another.

I see this in my workplace all the time.  My workplace I’m sure is not unique in this regard.  Those who deviate from commonly held beliefs or ways of doing things are shunned, or marginalised.  I have seen this happen to a former colleague.  Yet their contributions (as connectives) are incredibly valuable to the group or network.

Freedom vs. Control

Again, its about context.  The types of connections required to achieve certain outcomes are defined by the context in which they are to occur.  If you need to distinguish yourself from your competition for example, then a certain level of freedom is necessary to operate outside of convention to discover new innovations.  However, if working to a specific goal that must be shared amongst a collective, then a level of control is necessary to ensure the goal is met.

This was a fascinating presentation, and it resonnated with my life experiences considerably.

My position on Connectivism

This blog post relates to my study of CCK11, and is my submission for assignment 1 – my position on Connectivism.  As the word-limit is quite low, I’ve linked to previous blog posts which provide greater depth of discussion and links supporting my assertions.

Clarify and state your position on connectivism

I was very excited to be doing this course. I was introduced to Connectivism in my instructional design course as part of my program with UManitoba back in 2009.  At that time, I was unsure about Connectivism and wanted to learn more before forming an opinion on its validity as a learning theory.

My current role with my employer is an instructional designer.  My current value system for learning theories centres mostly on usefulness.  At this stage, I’m not convinced of its usefulness in terms of underpinning a learning design.  This isn’t to say that its not useful, I just haven’t enough experience with it to say that it is.  So I’m saddened to say that after 5 weeks studying Connectivism, I’m still largely a fence-sitter.  Hope this is okay George. 🙂

For me, I don’t think of learning theories in absolutes.  My view is that each learning theory is valid and useful, for given contexts.  I have blogged extensively on this view over the past couple of years, increasingly so in the past weeks.  I found a real nugget in a video by Ian Robertson that provided concrete examples to illustrate my view about context and learning theories. In this blog post, I reflected on what I thought were the right (and wrong) contexts for Connectivism where a primary factor (at this point) is technological accessibility where making connections is not so easy.  This is based on the importance George has placed on technological advancement as a primary driver for considering a new theory for learning.  Another significant factor is the discipline or focus of the learning, which I consider a weakness of the theory and discuss in greater detail later in this article.

Is it a new theory of learning?

For me at this stage, the stand-out elements of Connectivism that are novel are:

  1. Learning may reside in non-human appliances
  2. How can we continue to stay current in a rapidly evolving information ecology?
  3. Currency is the intent of all connectivist learning activities
  4. Decision-making is itself a learning process
  5. Capacity to know more is more critical than what is currently known
  6. How do learning theories address moments where performance is needed in the absence of complete understanding?

These aspects are the ones that resonate most with my life experiences as a learner.  However, these experiences have been very natural and organic.  This course as a MOOC is pseudo-organic.  Everybody has assembled to learn about Connectivism, but the learning is driven by a daily email digest, not purely by one’s own curiosity or need to solve a problem.  My reflections on this MOOC are detailed in a separate blog post.

Returning to the stand-out principles for me, I’d like to unpack these a little more…

Learning may reside in non-human appliances

For most of my adult life, I have been using computers to organise my learning.  It has become an integral part of how I learn.  Whether it be storing information, finding information, reflecting on ideas, sharing ideas, feedback and so on.  For many years, I rarely bother to commit to memory knowledge – I have honed my skills in being able to find it when and where I need it.  If I need to remember the switches to a UNIX command, I access the online manual (using the man command).  If I want to recall my previous thoughts on a topic, I refer to my blog.  If I need to follow a policy for a task at work, I search the policy portal.  The technology becomes an extension of my learning.  It’s more about learning to learn and self-sufficiency.  I recall George commenting that he would be lost if he were to lose the information on his computers, because it has become a fundamental element of how he learns.  I hope I have paraphrased that correctly George. 🙂  I feel exactly the same way.

How can we continue to stay current in a rapidly evolving information ecology?

I have been working in the IT and education industries for 15 years.  Both are very evolutionary and constantly changing.  From the beginning of my working career, I have had to develop strategies for this challenge.

Currency is the intent of all connectivist learning activities

This links to the previous paragraph – it’s all about remaining current in an evolutionary environment.  How can I systemically remain current in a rapidly changing environment.

Decision-making is itself a learning process

Again, this links to the previous paragraph.  Deciding what to learn and how deep to learn it is a critical factor in an age of information abundance.  Is what I learn today going to be applicable in the near future?  You need to constantly reflect upon what you believe to know – challenge previously held assumptions in the light of perpetual change.  This too has linkages with Dave Snowden’s view that we are pattern-matching intelligences, rather than information processing intelligences.

Capacity to know more is more critical than what is currently known

Again, a symptom of evolving contexts and related to decision-making.  What has worked in the past may no longer work due to changing context.

How do learning theories address moments where performance is needed in the absence of complete understanding?

This I can identify with again and again.  There are very few tasks or projects that I have worked on where I have known all that I need to produce a satisfactory output.  In my work history, there is very little repetitiveness – almost every day is a new challenge requiring me to develop new skills, ideas, ways of seeing the world.  I can only see this trend continuing.

What are the weaknesses of connectivism as formulated in this course?

Like all existing learning theories, their application is contextual.  I don’t think George considers Connectivism to be the silver-bullet of learning theories, and really its not.  Its just a theory that incorporates the information era of the 21st century and responds to the challenges of learning in this era, plus leverages the affordances of the technology of the time – global interconnectedness.

At times I wonder whether the discipline or topic area suits this style of learning design more so than another. Suifaijohnmak has written an article where he says:

… under a networked learning approach, where diversity of opinions are welcome in a MOOC, then tensions amongst different “voices” seem to be a natural emergence from the networks … This seems to be a natural opposite from the traditional “group” or “team”, or even the Community’s views where consensus and agreed goals are the norms rather than exception.

How do we know if diversity of opinions is the best way to learn under a networked learning ecology (or with internet)?

How do we know if diversity of opinions is the best way to learn full-stop?  Does learning and knowledge [always] rest in diversity of opinions?  Especially when you consider the traditional working environment is more about groups and teams working towards agreed goals.  Again, it depends on context.  Are we discussing facts or ideas, for instance.

What are your outstanding questions?

Continuing from the previous section, I’m curious as to what a connectivist learning design would look like for a course teaching a more hardened science, such as physics, chemistry or computer science.  I have asked George this question in an Elluminate session, but his response at least for me did not solve my dilemma – how do I apply this theory to more diverse contexts?  Learning isn’t always about sharing opinions.  Many of these disciplines are objective – a solution is either right or wrong.  The value of opinion (in my opinion) is significantly lower than in topical areas that are more culturally influenced, such as education – softer sciences if I may, just as an example.
