This presentation by Steve Wheeler has been causing some comments around the edubloggers networks. George Siemens responded saying “The development of the semantic web, linked data, and open data, coupled with location-awareness, recommender systems, augmented reality, data overlays, and similar developments is having a dramatic impact on how people interact with information and each other”.
For some time, I have been working at developing a Technology Enhanced Boundary Object (TEBO) to help Careers Advisers (PAs) understand Labour Market Information (LMI). But I am increasingly interested in how we can access and visualise live LMI as part of the careers advice process. These are notes I have written about the idea.
What is linked data?
The Web enables us to link related documents (from linkeddata.org). Similarly it enables us to link related data. The term Linked Data refers to a set of best practices for publishing and connecting structured data on the Web. Key technologies that support Linked Data are URIs (a generic means to identify entities or concepts in the world), HTTP (a simple yet universal mechanism for retrieving resources, or descriptions of resources), and RDF (a generic graph-based data model with which to structure and link data that describes things in the world).(Tom Heath, including excerpts from Bizer, Heath and Berners-Lee (in press))
What is the relationship between Linked Data and the Semantic Web?
Opinions on this topic differ somewhat, however a widely held view is that the Semantic Web is made up of Linked Data; i.e. the Semantic Web is the whole, while Linked Data is the parts. Tim Berners-Lee, inventor of the Web and the person credited with coining the terms Semantic Web and Linked Data has frequently described Linked Data as “the Semantic Web done right.”
Using Linked data with Careers PAs in the UK
Though the MATURE project we have undertaken extensive research and consultation with PAs in different Connexions companies including in England and Wales around the use of Labour Market Information in Careers Advice, Information and Guidance. Work undertaken through the project has aimed to allow research and easy access to documentation around different careers including LMI. We are also aware that all LMI requires interpretation – s stage of knowledge maturing – and one aim has been to allow easy forms of interpretation though tagging etc. A second aim has been to allow the development of an organisational knowledge base through sharing the results of LMI research. LMI is based on various data, collected by different government agencies and by for example the sector skills councils. In the past access to this data has been restricted. Additionally it requires considerable knowledge and skills to be able to manipulate and interpret large data sets. Inevitably much of the interpetation is over generalised and is frequently out of date.
Open Data
In autumn of 2009, a new web site was launched in the UK based on an initiative by Tim Berners Lee and Nick Shadbolt. Data.gov.uk seeks to give a way into the wealth of government data. As highlighted by the Power of Information Taskforce, this means it needs to be:
The aim is to publish government data as RDF – enabling data to be linked together. The web site says their approach is based on:
The new UK government has committed itself to backing this initiative and increasingly local government organisations are providing open access to data. Many of the key data sets for LMI are available through the data.gov.uk site including time series data on employment in different occupations, average earnings, job centre vacancies (at fine grained local office level and over a 10 year time series), qualifications, graduate destinations etc. along with more generalised but critical data such as post codes. All data can be queried in real time through a SPARQL interface.
Thus there is considerable potential to run queries and provide linked data providing valuable Labour Market and Careers information.
For instance:
A post code or location based query around a particular occupation could reveal:
By querying external databases this could be extended to include:
Where xcri course information data is available the app could provide information on local courses related to that career (Note – xcri data standard compliance is patchy in the UK).
Maturing Knowledge – the role of the PA
Whilst this system would be a great advance on anything presently available, it is not perfect. LMI data still requires interpretation. For instance job centre data has a known bias towards public sector employment, lower paid jobs and short term employment. The search only covers past data and may not reveal longer term labour market trends. Thus ideally following such a search the PA would be able to add brief notes before saving the search. These overall results could then be packaged to sent to a client as well as stored within the organisational system. To use the new information and knowledge sources being made available through the Careers Project requires new interpretation skills on behalf of the PAs. Thus the development of a linked data app would also be accompanied by the development of the TEBO which aims to provide informal learning for PAs around using LMI
Visualisations
Although a early version of the system might well be text based, it would enhance data interpretation to provide visualisations of the data.It may be possible to do this dynamically using for instance APIs to the IBM Open Source Many Eyes application.
I’ve just spent some time organising my Google docs into folders. Why? Because I have so many of them.
I used to use a very old version of Microsoft word for mac on my desktop machine. When I found it would not deal with docx formats I moved over to open office and Neo Office J. But at the same time I started using Google docs because of the ability to share documents. In fact I had already been using Wordly before Google bought it. However, it seems that Google sat on Wordly for a long time. Although Docs sort of worked it was still clunky compared to a desktop word processor. But with the latest upgrade to docs it now seems a better working environment than any of my local word processors. And off course I can access it from any of my computers or from my phone.
But what excites me is the casual and simple collaboration that online documents enable. Of course wikis always had that functionality. But somehow most of my experiments with collaboration with wikis didn’t quite work. People were unwilling to change another person’s work. And the mark up code was off putting for many.
Furthermore it is very easy to see who you can build an online portfolio using google apps or even a Personal Learning Environment.
So what is the downside? In one word – Google. Do we want to trust our working environment to a mega large multi national corporation making most of its money out of advertising. I sued to be sure that I did not. But now I guess I am getting more pragmatic. Google apps offers a lot of functionality and is free. Especially in present economic times free is good. Of course Google could disappear or do something I hate so much I do not want to use their software any more. But I am backing up my docs to a local version anyway. In some ways the debate is similar to the issue raised at the PLE conference in Barcelona as to whether institutions should be providing PLE applications for learners. My conclusion was that I do not really care who provides a Personal Learning Environment, as long as it is controlled by the learner. And as long as Google continues to allow that degree of control I can see myself increasingly using their applications. At least they are not Blackboard!

Its been a week off from the blog. Following the PLE2010 conference in Barcelona I took a short holiday. And since I have been back I have been fighting (unsuccessfully) a power failure in my office. So now I am squatting in a friend’s house and using my laptop.
I have much to say about the PLE2010 conference – I am not quite sure where to start.
Firstly it was a truly social conference – social in the both face to face and distant participants were involved in the different sessions. Social too, in the way the pre-conference discussions ran into the conference proper and then into the discussions at coffee breaks and in the evening. The formal conference was just one part of the whole event. And social in the use of media. Besides the live streaming of many sessions, it woudl appear the conference generated over 5000 tweets on the first day (the tweets are archived here).Indeed, for many of us it was the first chance to meet face to face people we have been collaborating with on line for a long time.
Much of this was down to the design of the conference. the pre-conference publicity and discuxxiosn had been focused on social media and in particualr twitter. And the programme design, from unkeynotes to cafe style sessions, debates amnd workshops, was signed to facilitate social interaction and participation. And it is encouraging that many have said they will relook at how they are organising conferences and draw on our ideas.
But what about the ideas? Firstly it was very heartening to see that we seemed to have moved beyond the stage of defining a PLE by what it is not i.e. not a VLE. Instead participants were looking outwards, at how to support learning. I am not sure how much we shared common understandings and meanings around PLEs (sadly I cannot find a record of the session which tried to arrive at such a common definition) but there seemed sufficient understanding for common debates.
One controversial issue was how far it was possible to provide an institutional PLE. This debate was driven by the folks from SAPO Campus in Portugal who are trying to do just that (and still managing to find time for late night and in depth analysis of the failings of the Portugese football team!). My own take is that I do not mind where the tools for a PLE come from as long as the leaner is in control.
Two ‘discourses’ particularly heartened me. The first was between educational researchers and practitioners and software and technical developers. This is an oft troubled discourse in the ed tech community. It may be that the common understandings around the idea of a PLE are allowing these different groups to work together in new ways. I particularly enjoyed the session on using Google Wave as a PLE and was impressed by the Talkingabout video sharing site. But what charatcterised these ideas – as in others I could not attend but heard from others about – was the innovation in appropriating technologies for pedagogic innovation.
Another – and more problematic but recurrent discourse was the issue of motivation. Participants were trying to develop PLEs with students inside the schooling and university systems. But surveys and anecdotal evidence suggests students are wary being overly focused on what work they need to do to pass exams, rather than exploring ideas and learning. And most students view direct didactic teaching as the best approach to passing their exams. As such they have little time for reflection or indeed little understanding as to why they should engage in such activity. This is problematic. We may consider their longer term learning important and thus view the development of meta-cognition and problem solving a priority. But perhaps inevitably under the present education systems their major concern is just to jump the next hurdle in the education race.
My only personal disappointment was that the major focus for PLE development and implementation for the vast majority of participants was for learners within schools and universities. There was limited interest in work based learning or in learning outside teh existing systems – the very areas where I think PLEs have the greatest potential.
Indeed, I think we have to consider the wider issue of where to locate the PLE debate. Clearly it is not just another instance of educational technology. But neither can it be easily subsumed in considerations of pedagogic approaches to the use of ICT for learning. I increasingly feel that the whole issue of PLEs is closely related to the ongoing discussions around open education. The very promise of PLEs is to understand the use of technology for learning in a new way, in a context where learning becomes part of society and is free and open to all.
But now there is a lot of work to be done. We have over 70 papers and many offers of publications. Most participants seemed to assume that PLE2011 was already on the cards (watch this blog for more news on that). And the bigger question is how we can use the ideas and networks generated by the conference to build a collective community of practice based on networking and sharing. Any thoughts or ideas very welcome.
This morning I met face to face with Alec Couros together with whom I am delivering the unKeynote presentation to the PLE2010 conference in Barcelonatomorrow morning.
We have crowd sourced the presentation. In response to the nine questions we posted 10 days ago, we have received over 25 replies, including slides, text, audio and video content. We have put all the slides together which will be the basis for the unKeynote tomorrow. You are all invited to take part. We will have roving microphones for those of you lucky enough to be with us in Barcelona. And for those of you who cannot be her face to face, just ask your comments or ask questions using the #PLE_BCN hash tag. Cristina Costa and Joyce Seitzinger (better known to the Twitterati as Catspyjamasnz) will be monitoring the twitterfeed and bringing to our attention your tweets. We are going to work with three screens – one for the crowd sourced slides, one for twitter and a third for our skrbl boards. For each of the key questions we have set up an open Scrbl board for participants. And if you don’t want to wait until tomorrow – you can contribute your ideas on the skrbl boards now. Here are the questions and the urls for the scrbl boards. The unKeynote runs from 9.15 to 1015 CET tomorrow (Thursday morning) and there are rumours it will be streamed (watch the hashtag tweets for details).
UPDATE – you can watch live stream from here – http://eventv.projectescitilab.eu/index.html
And after the presentation we will be publishing our works and yours – together!
