50 years on my Computer Science School voted #1

Great to see my alma mater University of Birmingham School of Computer Science and  IT coming #1 in the Guardian University Guide 2014.

Reading for an applied maths degree I took the first ever FORTRAN course offered in September 1963 exactly 50 years ago. Overnight this single course changed my career and I have been studying, teaching and researching computer science every since.

My GrannyBook Raspberry Pi Emerges

At the first MakerCamp on the Gold Coast we were asked to suggest a project we were working on. I suggested I would like to make a GrannyBook based on the Raspberry Pi, the $35 computer I estimated would do the job. Loosely defined, my idea is for a very cheap device, under $100, that would allow your granny to turn her old Windows XP box into something akin to a Chromebook. In other words any person with an obsolete PC that still works could throw out their old processor box and replace it with a small device that would boot straight to a browser within which all normal use of a computer could be conducted - a very cheap and easy cloud computer.

I duly purchased a $60 the Raspberry Pi kit from Steve at Gold Coast Techspace which included the Raspberry Pi board, an SD card completely configured with the OS and an HDMI cable. On eBay Australia I bought a clear acrylic case for less than $10. To use my existing monitor I had to add a $5 HDMI to DVI adapter. Finally with another eBay purchase from the shop that supplied the case I added a $10 Comfast Wi-Fi adapter rather than use the built-in Ethernet port. In total this amounted to a $85 investment.

After plugging in a USB keyboard I added a standard non-powered USB adapter to take a USB mouse and the Comfast Wi-Fi adapter. Then came the big moment of the first boot and true to form the RPi within about 15 seconds opened in the desktop having determined the monitor resolution perfectly. To my surprise and delight there were drivers present for the Comfast Wi-Fi adapter and I simply had to login to my home Wi-Fi network.

The on-board Midori browser fired up perfectly and I logged in to my Google account. Thereafter I was in the usual Google wonderland with access to email, calendar, sites, blog, and all the other goodies - in other words a good approximation to a Chromebook.

The inevitable downsides are present:

• the less than lightning speed of the boot sequence compared to a real Chromebook
• the pauses as web pages are loaded in the browser although performance overall is very adequate
• the lack of Google Chrome and associated plugins, but further investigation might solve this

Nevertheless for a very small investment and an hour of my time I am well on the way to a viable GrannyBook. More anon.

Activity 24 Considering open learner literacies #h817open

The list of literacies provided by Jenkins et al in their occasional paper on digital media and learning is duplicated here. I have marked in bold those literacies I feel are particularly appropriate to open online learning, although it seems obvious all literacies in the list are beneficial at one level or another.

1. Play – the capacity to experiment with one’s surroundings as a form of problem solving
2. Performance – the ability to adopt alternative identities for the purpose of improvisation and discovery
3. Simulation – the ability to interpret and construct dynamic models of real-world processes
4. Appropriation – the ability to meaningfully sample and remix media content
5. Multitasking – the ability to scan one’s environment and shift focus as needed to salient details
6. Distributed cognition – the ability to interact meaningfully with tools that expand mental capacities
7. Collective intelligence – the ability to pool knowledge and compare notes with others toward a common goal
8. Judgement – the ability to evaluate the reliability and credibility of different information sources
9. Transmedia navigation – the ability to follow the flow of stories and information across multiple modalities
10. Networking – the ability to search for, synthesise and disseminate information
11. Negotiation – the ability to travel across diverse communities, discerning and respecting multiple perspectives, and grasping and following alternative norms.

I note that in previous posts in this series I have referred to Judgement as significance and Collective Intelligence as curation, but the intent of my terms exactly aligns with Jenkins et al. In my post for activity 22 I addressed at length the need for PINC tools and literacy to support collective intelligence. Judgement is much more difficult and complex. Advanced search skills allow sophisticated discovery of resources, but determining reliability and credibility is highly specific to the unit of study being undertaken. Obviously the skill and experience of instructors plays a major role but they must be able to codify these measures that I collectively call significance. A set of rules and guidelines must be produced that students can follow to produce consistently a degree of judgement to be relied upon.

Appropriation has a degree of overlap with transmedia navigation in my view as following story flow gives the necessary context to the media content being appropriated. Significant media literacies are needed to take an assumed finished product, itself the result of potentially many hours of production, and make meaningful changes so as to reuse the product in a new context. Skills might include rewriting, diagramming and charting, image manipulation and animation, and audio and video editing. It is no wonder that media courses for these skills are in high demand. It is also not strange that a typical university teacher lacks this valuable combination of skills.

Distributed cognition requires the use of outliners, mind maps and other topic association tools. Even if the tools are well designed and straightforward to use a significant trail of experience is needed to extract benefit from these tools. If lecture notes and academic journal papers are any indication then much more experience is needed.

I would think that networking skills are best acquired by judicious use of a variety of social networks used with a degree of focus. Careful selection of 'friends' depending on your perceived quality of their information flow must be acquired over time. This same strategy can be employed on the ubiquitous forums that are usually present for all MOOCs.

Negotiation defined here as the ability to cross disciplines and appreciate different perspectives is a necessary and underrated literacy. Little attempt at teaching this in the walled gardens of university disciplines means there is a definite niche for open education to fill.

This activity has caused me to think and reflect as much as any previous activity in this course. My thanks go the instructor for setting this task.

Activity 22 An open education technology #h817open

I have mentioned before in this series (activity 19)  the need for students to be able to collect together links to the resources given to them on a course merged with those resources discovered by themselves. Let's refer to this tool category as PINC (PLN Information Node Curation). A PINC tool, most usefully a cloud app, will have these features:

1. a central repository of information nodes (links and documents) culled over a lifetime of learning; by definition this should be capable of:
• information node insertion/edit/deletion
• convenient searching
• export in convenient formats
2. a personal tagging/labeling system to structure what is likely to be a very large collection
3. the ability to share any or all information nodes (make public and maybe more targeted sharing)
4. quickly accessible over the Internet from a wide variety of devices to include smartphones, tablets, laptops, even wearable devices; some devices will allow local storage for off-net access
5. automatic backup and ability to download all information for archiving purposes

In my experience some existing apps come close to these PINC requirements although none meets them completely:

• Evernote: a widely used app/service that can store a very large range of information types and now has easy sharing
• Diigo: primarily a link repository that took over and expanded upon the early now reincarnated Delicious service; this repository is only useful if all information nodes are resource links
• Mendeley: primarily a citation repository which is widely used to share academic references as well as links; PDF and data files are also handled well; the recent takeover by Elsevier casts doubt on its long term survival

All the suggested PINC apps come with free versions although the paid service offers not only more features but also promises more longevity, a major requirement for a service that will be needed over many years.

It was pleasing to see the early creation of a shared Diigo list of references for this Open Education MOOC but it appears not to have survived week 1. The excellent list of references provided for us on #h817open are currently scattered over several OpenLearn pages. It would be more useful if all references were gathered together in a public repository of some sort that will survive the end of the Open Education MOOC.

I would be very happy to hear of alternative PINC tools that other people are using. Please comment below.

Activity 21 How technology and pedagogy inter-relate #h817open

My own experience is coloured by my 40 years of teaching computer science and always seeking to employ the latest computer and networking technology to improve my teaching. I spent over half of this time in my last institution and notched up a number of firsts that include:

• first online test (Macintosh 1991)
• first web site (1995)
• first web forum (1996)
• first 'LMS' (SharePoint, 2000)
• first student assessed blogs (2005)
• first pilot with BlackBoard (2006)
• first virtual teaching laboratory (VITTL, 2008)
• first lecture screencasts (2009)

Throughout this process I faced uphill battles to co-opt my colleagues and have ploughed a reasonably lonely but exhilarating furrow. Nevertheless I venture to suggest all these technological advances are now recognised as bringing significant improvements to the teaching process. At the same time it is realised all bring concomitant changes, sometimes very substantial, to teaching preparation and presentation.

Looking back over the years I estimate I spent between 15% and 20% of my time keeping abreast of advances in technology. A small proportion of the outcomes of this effort found its way into the curriculum of  the subjects I taught. The larger proportion of the technological changes affected society as a whole, and, of course, the students coming on campus. Thus the major pressure comes from changes in the way society communicates and that inevitably cause a change to education itself. I firmly believe that all activate educators must spend of the order of 10% to 15% of their own time keeping abreast of technological advances if they are to remain effective educators, not to mention staying in step with the society in which they live.

A couple of years ago just before retirement I was pleased to find the smartphone and tablet revolution was being recognised by a much larger group of colleagues including myself. In my last year of full-time work I did not feel alone in the pursuit of applying new technology to better higher education.

Activity 20 Exploring rhizomatic learning #h817open

I watched Dave Cormier's video on rhizomatic learning with enthusiasm and found myself sympathetic to the ideas put forward. The actual metaphor of the rhizome does convey some of the ad hoc nature of the information nodes gathered from a personal learning network and how an individual approaches learning a collection of topics. I somewhat doubt the community at large is familiar with rhizomes. As a computer scientist I would rather think rather in terms of information nodes in meshes or nets, particularly sparsely populated ones. So I would be tempted to use the concept of a personal learning mesh.

That said I wholeheartedly agree with the notion that the best teaching prepares people for dealing with uncertainty. In teaching computer science over 40 years I have always spent a great deal of time on the leading edge technological changes and urged students to look ahead. However influences by colleagues I have always been persuaded to teach the set of basic computer science concepts which we all know have evolved in significant ways over the decades.

Only in the last 5 years or so of my teaching did I introduce any part of the idea that the community (students) can help modify the curriculum. Usually half way through a subject I would map out some choices of study and invite other contributions from interested students. [Note this meant breaking the 'contract' set by the subject outline set 6 months or so in advance and containing the topics taught in each week of the subject.]

A recent email from a  Masters student I taught just 15 years ago contained an admission he was no longer an expert in ICT and was seeking work in office management instead. I believe if he had a stronger personal learning mesh along with the habit of continual update he would be better served. He has obviously not taken enough responsibility for maintaining his own learning (in ICT).

While I again agree strongly that learning cannot be measured accurately this goes counter to the attempts to ensure so-called measurable 'graduate attributes' that my previous institution now insists be done.

So I find myself in general agreement with the precepts of rhizomatic learning  but feel traditional higher education finds itself at odds them.

Activity 19 Implementing Connectivism #h817open

[Note: connectivism principles are highlighted in italics.]

I described the main topics in my Digital Literacies subject in the post for activity 8. In common with other instructors I would provide a set of 'prime' sources for each topic, deliberately limiting them in number. For each topic, essentially one facet of network and computer technology, I would take a definitive stance on the effectiveness of that technology - I would state an opinion. Students would be invited to pose different opinions to encourage a diversity of opinions.

Students would need to search and discover additional resources to support these opinions and be shown how to connect all resource links using shared repository tools such as Mendeley. This would introduce the process of connecting specialised nodes of information sources. As per my comment on activity 17 I would develop with class input a series of significance measures to judge the quality of the resource links (nodes) developed for the information sources. These measures would include currency and a determination if the resource is more critical than what is currently known. Much guidance on the authority of authors and the place of blogs, tweets and other social media status updates needs to be given and a set of guidelines established that evolve as the course progresses.

Most of the aspects of modern digital literacies are strongly interlinked and assessments for the students would encourage them in their ability to see connections between literacies. The course would strongly suggest that they continually evolve this refinement of the connection mechanism to nurture and maintain connections to facilitate their continual learning beyond the end of the course. Indeed this should become a habit for the remainder of their lives.

Activity 16 Examining a definition of Personal Learning Network #h817open

I define a personal learning network, PLN, as:

A loose but evolving collection of people connected by cloud apps on the Internet and whose views and information on topics of interest to me, both personal and professional, I find are of benefit to my daily activities, in other words my continual lifelong learning.

My first disagreement with the Wikipedia definition of PLN is that I regard my own PLN as both formal and informal. Over the last 8 years or so with blogging, Facebook and then Twitter my PLN was been used largely for professional purposes where information provided to me or elicited by question has been used for learning to better at my profession - university teaching. In turn I have responded in kind with all the people in my PLN.

Certainly the composition of the people in my PLN is informal and can change on a regular basis as my professional and personal interests change. Social media apps make the maintenance of the people group straightforward.

From Education Technology Guy
educationaltechnologyguy.blogspot.com

Much of the literature tends to emphasise the communication technologies and tools used to create and maintain a PLN. Diagrams like those on the left list huge lists of web sites and cloud apps, in other words the tools that can be used to communicate synchronously and asynchronously with people in your PLN usually social networks of some kind.  Other apps are included that provide the personal publishing mechanisms that allow each person to be creative and easily share their work with others.

These tools are vital of course to the operation of you PLN in my view are not the main focus of how your PLN facilitates you learning. Of necessity many of the tools come and go over sometimes very short period of months or a year or two. It is therefore vital for each individual to use a variety of tools and test them on the basis of how many useful people employ the same tool and hence can join your PLN. Trying out new tools should become second nature but only continue with a new tool if the community it supports yields benefits and the tool itself is compatible with the usual set of tools.

From Kegg Apoptosis
http://www.flickr.com/photos/sjcockell/

Of primary importance always is the people network that is at the heart of your PLN. If your tools provide a connected network report it should be used regularly to check the effectiveness and reach of your PLN. It is the people and the links to their artifacts that form the core of your learning.

Usually the amount of information generated by your PLN is excessive and a strategy for winnowing out the gems is needed with the help of yet more curation tools, another category of tool that must be investigated.

Activity 14 Comparing MOOCs #h817open

I chose to compare Change MOOC with Udacity CS253 Web Apps Engineering (now called Web Development), a course I completed and received a high grade.

Technology

Udacity CS253

Change MOOC

As might be expected Udacity has invested in a propriety MOOC platform designed to meet its early courses which are mainly in the STEM disciplines. The MOOC platform is centred around a sequence of lessons each consisting of a series of many short videos (about 20) which are a mix of talking heads, an electronic handwritten whiteboard with narration, in-video quizzes along with instructor notes when needed. The critical ability to navigate between videos and quizzes has steadily improved over time from the crude next/previous links of the early courses. Within a lesson the student can quickly move to any video/quiz component with a simple click. A course wiki contains lecture notes and associated written material and links to other material. The primary interaction locus for student is the forum. 12 months ago this was a fairly standard forum, but it is good to see that a useful structure based around the units and the problem sets not applies. Essentially this is structured hashtagging that allows easy searching for discussions around the main course components. Of course the main communication timeline from instructors to students is via email.

From the course outline we find participants will use a variety of technologies, for example, blogs, Second Life, RSS Readers, UStream, etc. Course resources will be provided using gRSShopper and online seminars delivered using Elluminate. In other words the participants choose from a wide range of publicly accessible shared communication tools. Some like Second Life and Elluminate was highly interactive at scale and allow frequent and personal interactions between participants. Elluminate is most effective when used in realtime and offers a way to access an instructor directly. A real benefit here is that each participant can choose the set of tools with which they are familiar thus substantially reducing the technological friction allowing more time for interaction on the course.

Pedagogy

Udacity CS253

Change MOOC

A basic sage on the stage pedagogy is used with the videos/wiki providing the main content delivered from the sage. The MOOC platform guides the student through the linear lesson plan with automatically assessed quizzes and problem sets along the way. A simple but impressive web-based integrated coding environment is used for some quizzes and scripts provide immediate feedback. Assessments use the third-party Google App Engine and automated scripts provide feedback if their are problems and the final passing grade when appropriate. There is some instructor video feedback for common questions and problems determined from forum posts. Some key forum posts receive direct feedback from the instructor or teaching assistants. Otherwise peer discussion goes on via the structured forum and provides ad hoc peer interaction. Some natural student groups form in external social media such as Twitter, Google+ and Facebook.

Being a course spread over 36 weeks with over 30 invited speakers it is difficult to compare with a 7-week xMOOC. The range of speakers and topics was hugely impressive and covered all leading-edge work in instructional technology. Probably most participants would choose the topics of direct relevance leading to highly personalised learning. The highly relevant daily newsletter created with significant effort by the course facilitators contains a topic and relevant recent blog posts and tweets from participants - together these form a large course archive for use beyond the course. From his keynote at THETA13 The Higher Education Technical Agenda conference in Hobart Alec Couros gave a very succinct description of the pedagogy on cMOOCs:

General approach and philosophy

Udacity CS253

Change MOOC

This was a practical course with well-prepared, very short videos which could be consulted and repeated easily as often as necessary. I found the forums useful to help solve problems particularly with the practical work. Even though I had taught a very similar course myself I learned a considerable amount. For students in control of a study discipline and a willingness to consult their peers when running into problems this traditional approach is highly effective. Student with insufficient background will drop out having received an appreciation of the required standard and been given the opportunity to repeat at a later time.

Those participants who make it through the course not only receive a thorough understanding of the current state of ed tech they have effectively built a personal learning network. The latter will encompass a wide range of creative skills using publicly accessible cloud apps together with the momentum to continue to interact with the cohort of active course participants. They will have absorbed the philosophy for their own course of providing just a skeleton course structure and have the students fill out the content most relevant to them.

Avoid getting hooked on the concept of the virtual MOOC University

In this article about grading the MOOC university A J Jacobs makes the mistake of following the hype of the MOOC providers that claim this is the future of higher ed as we know it. This misses the point that MOOCs are a different, alternative paradigm that will evolve to become the way to acquire the skills and competencies needed for paid work, self employment and day-to-day living in general.

Even AJ acknowledges:

MOOCs provided me with the thrill of relatively painless self-improvement and an easy introduction to heady topics

Starting from a suitably early age why would a person ever need hugely expensive, increasingly overrated higher ed which less than 1% of the world's population can afford?

Activity 12 Background to MOOCs #h817open

It is good to look back at the history of MOOCs and the influences and context that brought them forth. Martin's interview with George and Dave gives an excellent sense of the pedagogical challenges that were taken on and solved to a large extent in the early cMOOCs and are still confronting the xMOOCs today.

The lengthy report by McAuley et al being written 3 years ago and predating xMOOCs seems like ancient history and almost 2 MOOC generations old. Even Martin's MOOCs Inc post with the important link to Curt's May 2012 massive link bait seems to exhibit peeling MOOC paint. Curt admits that even back then he had too much reading, watching and listening to do to catch up on MOOC developments. So how much harder is it today?

The last subject I taught at my own institution before retiring was entitled Web Applications. Subsequently the first MOOC I took as a student was Udacity's CS253 Web Apps Engineering now called Web Development. So can a MOOC compete with a traditionally lectured subject? You bet it can. In 7 weeks of  the CS253 MOOC Steve Huffman and 1 TA covered about double the amount of material of my 12 weeks of lectures.

As it happens we both used Google App Engine for the practical work and this allowed direct comparison. I taught about 15 students and Steve at least 1,000 times that number. What I found most impressive was how App Engine allowed the used of automated assessment scripts so that students were able to receive direct and useful feedback with comments on their practical work 24/7. To moocify my own course would be very straightforward.

The drawbacks would be that my institution markets and prides itself on small class face-to-face teaching. Also I believe most of the weaker students would struggle after about 3 weeks of the MOOC pace, probably explaining the high dropout rates from which most MOOCs experience.

As far as I know the furthest my previous colleagues have come is to put up course lectures and special presentations on iTunesU, where I have to admit they receive acceptable viewing rates. A noticeable trend is that the shorter the 'lecture' the higher the viewing figures.

Activity 11 Pros & Cons of big & little OER #h817open

In a couple of my previous posts for this MOOC specifically on location OERs for a digital literacies course and OER issues I have complained of various difficulties with what our instructor is calling Big OER. These difficulties mainly relate to searching and discovery, reusability and pertinent for this activity the granularity of OER. Long lectures peppered with irrelevancies and voluminous course notes carrying unwanted side issues are the main problems. Reuse of these Big OERs therefore mitigates against reuse without substantial remixing involving the same level of work by the instructor as starting from scratch.

Taking Martin's Collateral Damage slidecast as the queue I find I have always been in sympathy with the view that it is the collection of simple digital artifacts easily made widely available online that form the most useful educational material for my own courses. As Martin points out these artifacts are easily produced with simple online publishing services many of which are free, and, most importantly, don't require specialist broadcasting skills beyond those possessed by the typical lecturer. Most usefully too is these Little artifiacts tend to be byproducts of normal academic activities producing outputs like papers, code, lectures, recorded debates, conference talks, data, ideas, and workshop materials.

I like the thought of this long tail of academic outputs, often produced out of research activities, finding immediate use in teaching. At last we have a demonstrated direct link between research and teaching. This needs further emphasis to encourage many of the reporting and administrative activities to be made more visible and accessible online as part of the normal production process. The academic becomes a perfect long tail production engine. We owe a debt to Martin to giving this process an acceptable and impressive name - digital scholarship. These Little OERs also make impressive background materials for public engagement with world community, an increasingly important aspect for all academic endeavours.

Of course discovery of these Little OERs or digital artifacts still remains a problem. Maybe the universal adoption of hashtags in all online publishing platforms might be a step towards a solution provided the content is searchable by Google or more specialised search engines.

Activity 10 Applying sustainability models #h817open

I consider a number of open education initiatives and after a brief look at their web sites attempt to determine which of the three funding models, MIT, USU and Rice, proposed by Wiley in his OECD report are being used.

• Change MOOC: the facilitators are the cMOOC kings who seemed to provide their time gratis with the apparent help of volunteers. Certainly the 30 or more speakers, one per week, provided their input freely and to great affect. It would seem that the Rice model is being used here.
• Coursera: set up as a private company but still offering free MOOCs prepared by a large consortium of high-profile universities around the world but with most being in the USA. Each MOOC is prepared professionally with the cost met by member institutions. The total team size of full-time equivalent staff is likely in the thousands. Coursera presents and operates as a single entity so I would put them in the MIT category.
• Jorum: funded by JISC (a UK charity) collects and shares learning and teaching materials allowing for reuse and repurposing.  Although the materials served are free for reuse Jorum is supported by full-time professional staff so again is more akin to the MIT model. Since the OERs in the Jorum repository are obviously provided by a wide range of 'volunteer' contributors across the globe it could be argued this is like the USU model as well.
• OpenLearn: operated entirely by the Open University UK to provide MOOCs to the world. This would seem to definitely conform to the MIT model.

From the chosen open education initiatives it would appear the MIT model carries much weight. Wiley's model categories seem a sensible spectrum but it is obvious elements from two of more of his models are mixed in practice.

Activity 9 My choice of licence for my creative works #h817open

Asked to choose a licence for my own creative works, both in a professional capacity and for personal uses, I would choose probably the weakest Creative Commons licence CC-BY.

I believe the attribution requirement (BY) is sufficient for me to be satisfied that I will receive recognition for my work when it is copied, reused in new contexts and remixed in new uses. These hopefully will be many and varied. My only regret is that I as an individual and even with the search power of Google will be unlikely ever to know the full extent of any reuse in scope and over time.

There is a temptation to add the not-for-commercial-use (NC) provision but I am persuaded by Erik Muller in his case against the NC provision. I feel the reduction in basic and beneficial uses that NC will force is real. Also any thought of sharing in a potential profit from commercial use is dashed by the inevitable complexity of legal agreements and the time taken to prepare them.

The share-alike (S) provision sounds excellent in principle but highly likely to be ignored when the work is reused. Also there appears to be no productive method of following the trail of sharing to police or even just to check that the provision has been followed. If my work is incorporated into a successful commercial work the attribution of my contribution would be valuable in raising a digital profile.

CC-BY is good enough for me.

OER Repositories Search Results

General impressions of locating suitable material from each repository by week:

Ariadne: 1: medium, 2: medium, 3: poor, 4: very poor, 5: medium
Jorum: 1: good, 2: good, 3: good, 4: very poor, 5: medium
Merlot: 1: good, 2: good,3: good, 4: medium:, 5: good
MIT: 1: medium, 2: medium,3: medium, 4: medium:, 5: good
OpenLearn:  1: medium, 2: medium,3: medium, 4: good:, 5: poor
Rice Connexions: 1: poor, 2: poor,3: poor, 4: poor:, 5: good

Difficulties faced included:

• locating a suitable education level for such introductory material; most courses or modules were multi-week or simply too extensive and would need considerable contraction amounting to an effective rewriting of the content
• the significant effort required to drill down to sufficient detail in each OER found by the initial search to determine the suitability of the material
• a worryingly high number of broken links to OERs which highlights the sustainability problem
• some much of the material in the OERs was old and out of date, a big problem for the very fast moving topic of digital literacies

I found that Merlot which gave access to different types of course materials not just whole subjects was the most appropriate source of OERs readily usable without a great deal of detailed rummaging and research.

5 year technology outlook for Australian Higher Ed

The Technology Outlook for Australian Tertiary Education 2013-2018 has just been published without many surprises. The context with previous reports and research provides a look at trends:

The 1-year horizon is predictable with the vague social media topic being unhelpfully broad. I had already predicted that 3D printing would move to a closer horizon as its influence is growing at a great rate. It is good to see virtual and remote labs coming into the 5-year horizon but I had introduced virtual IT teaching labs to Bond in 2008, exactly 5 years ago.

As always the report makes good reading.

Activity 7 Exploring OER Issues #h817open

I firmly believe in the Open Educational Resources philosophy outlined by Downes (2007) as a collective social product to be shred universally. The OER movement has foundered on the over-engineering of the learning object and metadata technologies used in the disparate repositories. It seems to be pointless to continue to plough monetary resources into the current OER implementations.

The three problems from my perspective are:

1. Re-usability. The unit of a whole course is too cumbersome and over complex, and by its very nature will have non-useful, specific institutional context that immediately impacts on the OER being re-purposed elsewhere.
2. Granularity. Recordings of typical university lectures 1-2 hours in length are simply not useful for students. One aspect that MOOCs have shown us is that video lengths of up to 10 minutes only are effective. The same remarks apply to slide shows, audio, animations and simulations, and of course text readings. Keeping them small and reasonably standalone allows for remix to suit local requirements.
3. Onerous metadata and storage. The complexity of the OER objects and their metadata from the perspective of preparation, deployment, discovery and reuse means the technology is expensive in terms of time and expense. A major rethink of the technologies employed is needed with an emphasis on instructor self-publishing models with automatic sharing and hashtag-like metadata.

The problems of IP and copyright will inevitably remain until CC BY becomes the norm for all educational materials - a distant hope at this point in time.

Note: For a MOOC there should be an iron rule, all readings must be open access on the web. Many of the Academic References on the Cloudworks suggested OER reading list failed this test miserably. Even those with URLs are not marked as links on Cloudworks. A typical student on a MOOC is unable to access closed academic journal papers.

Studying the Open Education MOOC from OU UK

As an avid supporter of MOOCs will form the future of all open education I have enrolled as a student in the Open Education MOOC offered by the Open University UK. The distinguished education technology guru +Martin Weller is the lead instructor. I hope to learn about the pedagogy behind MOOCs for my own talk to my local higher ed institution where I hold the honorary position of Adjunct Prof.

To regular readers of this blog please note that all posts tagged with the #h817open label are work items submitted to this MOOC. Such posts may not be directly relevant to cloud matters per se but will be of interest to cloud education at least.

Netbooks live on in Chromebooks

I loved netbooks and actually still use my Samsung N210 occasionally. Over a period of 4 years I owned 3 models of Eee PCs, an HP (free at a Microsoft conference) and the trusty Samsung. Yes they were slow and all but the Samsung keyboards dodgy, but they were small, light and rugged (great for conferences/meetings). You could also buy 3 or 4 netbooks for one laptop. Being a cloud fanatic my latter netbooks interacted with my documents and data online, the browser being my most used locally installed app.

As I suggested almost 2 years ago we now have Chromebooks with the same form factor (although as a consumer I can’t buy an Australian version yet). They are much, much more responsive, more secure and allow you (force you) to live in the cloud.

A significant number of manufacturers are jumping on the Chromebook bandwagon. With the announcement of the HP Pavilion Chromebook we see the screen size grow to a weighty 14 inches. Such developments are starting to scare the tablet- and smartphone-toting users, see Jared Newman’s Time article entitled ‘Please, Chromebooks, Don’t Turn into PCs‘. He gives a good summary of Chromebooks available in the US when talking about the HP Chromebook:

The device is available now for $330. That’s pricier than some other Chromebooks like Samsung’s Series 3 ($250) and Acer’s C7 ($200), but cheaper than the Samsung Series 5 550 ($450), which is far and away the best of the bunch. Lenovo makes a rugged $429 Chromebook, but it’s for schools only.

It is definitely time for the Chromebook naysayers to wake up. I can’t wait to order one of the above.
