Il Foro

Last week I attended the Il Foro Conference in Baeza, Spain. This annual meeting brings together staff from the 10 universities in Andalusia who are involved in creating and running a shared virtual campus – Campus Andaluz Virtual. The focus of this conference was sharing best practice around teaching and learning strategies. The conference committee asked me to present about the role of standards in elearning.

Part of my reason for accepting the invitation to present was around my own PDP. I am trying to learn Spanish just now, so this seemed an ideal opportunity to practice. The thought of a bit of winter sunshine may have helped sway the decision too! Even with my limited knowledge of Spanish it was interesting to see how many similar issues around student engagement, creativity, web 2.0, mobile technologies and most importantly effective use of technology were being debated during the three days.

The virtual campus is a totally online option for students, with each of the universities offering a selection of courses to students in any of the participating Universities. There is a main portal which then links to each institutions learning environment.

In terms of my own learning and use of technology, having a Spanish dictionary on my ipod and google translate to hand did allow me to follow more quickly and easily and less obviously some of the bits I didn’t understand than I would have been able to without them. Though most web 2.0 terminology seems to be universally in English, reminding me of debates around the “e” in elearning standing for English.

The contrast to the conference surroundings to the CETIS conference in Birmingham the week before was quite also quite stark. Nothing against the Lakeside Centre but it really can’t compete with this:

And the wifi worked perfectly:-)

My presentation gave an overview of CETIS and our development from a JISC project to our current status as an innovation support centre, our work with standards and our changing working practices. I think it’s only when you explain to people outwith the UK the level of support JISC provides to our sector, you really start to (re)appreciate what a valuable contribution it makes to developing infrastructure and take up and use of technology within our sector.

Another personal reflection was my decision to use a ‘traditional’ power point presentation with the oh so unfashionable bulleted list. I know, in one of Martin Weller’s futures I would have been condemned for that. I had thought I would do a prezi with lots of pictures etc, but actually as my presentation was being simultaneously translated and I had to send it in advance, I think it actually made more sense to be a bit text heavy. It meant that my translator knew in advance I was going to use some not very common words and acroynms. It also meant that those in the audience could do what I had been doing early and use their ipods etc to translate themselves. If you are interested, the slides are available from slideshare.

The headless VLE (and other approaches to composing learning environments)

CETIS conferences are always a great opportunity to get new perspectives and views around technology. This year it was Ross MacKenzie’s somewhat pithy, but actually pretty accurate “so what you’re really talking about is a headless VLE” during the Composing Your Learning Environment sessions that has resonated with me the most.

During the sessions we explored 5 models for creating a distributed learning environment. :
1 – system in the cloud, many outlets
2 – plug-in to VLEs
3 – many widgets from the web into one widget container
4 – many providers and many clients
5 – both a provider and a client
Unusually for a CETIS conference, the models were based on technologies and implementations that are available now. (A PDF containing diagrams for each of the systems is available for download here)

Warwick Bailey (Icodeon) started the presentations by giving a range of demo of the Icodeon Common Cartridge platform. Warwick showed us examples the plug-ins to existing VLEs model. Using content stored as IMS Common Cartridges and utilising IMS LTI and web services, Warwick illustrated a number of options for deploying content. By creating a unique url for each resource in the cartridge, it is possible to embed specific sections of content onto a range of platforms. So, although the content maybe stored in a VLE users can choose where they want to display the content – a blog, wiki, web-page, facebook, ebooks etc. Hence the headless VLE quote. Examples can been seen on the Icodeon blog. Although Warwick showed an example of an assessment resource (created using IMS QTI of course) they are still working on a way to feed user responses back to the main system. However he clearly showed how you can extend a learning environment through the use of plug-ins and how by identifying individual content resources you can allow for maximum flexibility in terms of deployment.

Chuck Severance then gave us an overview IMS Basic LTI and his vision for it (model 2). Describing Basic LTI as his “escape route” from existing LMSs. LTI allows an LMS to launch an external tool and securely provide user identity, course information, and role information to that tool. It uses a HTTP POST through the browser, secured by the OAuth security. This tied in nicely with Warwick’s earlier demo of exactly that. Chuck explained his visions of how LTI could provide the plumbing to allow new tools to be integrated into existing environments. As well as the Icodeon player, there is progress being made with a number of systems including Moodle, Sakai and Desire2Learn. Also highlighted was the Blackboard building block and powerlink from by Stephen Vickers (Edinburgh University).

Chuck hopes that by providing vendors with an easy to implement spec, we will be able to get to the stage where there are many more tools available for teachers and learning to allow them to be real innovative when creating their teaching and learning experiences.

Tony Toole then presented an alternative approach to building a learning (and/or teaching) environment using readily (and generally free or low cost) available web 2 tools (model 3). Tony has been exploring using tools such as Wetpaint, Ning, PBworks in creating aggregation sites with embed functionality. For example Tony showed us an art history course page he has been building with with Oxford University, that pulls in resources such as videos from museums, photos from flickr streams etc. Tony has also be investigating the use of conference tools such as Flash meeting. One of the strengths of this approach is that it takes a relatively short time to pull together resources (maybe a couple of hours). Of course a key draw back is that these tools aren’t integrated with existing institutional systems and more work on authorization integration is needed. However the ability to quickly show teachers and learners the potential for creating alternative ways to aggregate content in a single space is clearly evident, and imho, very appealing.

Our last presentation of day one came from Stuart Sim who showed us the plugjam system he has been developing (another version of model 1). Using a combination of open educational standards such as IMS LTI and CC, and open APIs, plugjam allows faculties to provide access to information in a variety of platforms. The key driver for developing this platform is to help ‘free’ data trapped in various places within an institution and make it available at the most useful point of delivery for staff and students.

So, after an overnight break involving uncooked roast potatoes (you probably had to be at the conference dinner to appreciate that:-) we stared the second half of our session with a presentation from Scott Wilson (CETIS and University of Bolton) on the development of the Wookie widget server and it’s integration into the Bolton Moodle installation (another version of model 1). More information about Wookie and its Apache Incubator status is available here. In contrast to a number of the approaches demoed in the previous session, Scott emphasised that they had chosen not to go down the LTI road as it wasn’t a generic enough specification. By choosing the W3C widget approach, they were able to build a service which provides much greater flexibility to build widgets which can be deployed in multiple platforms and utilise other developments such as the Bondi security framework .

Pat Parslow, University of Reading, then followed with a demo of Google Wave (model 4) and showed some of the experimental work he has been doing incorporating various bots and using it as a collaborative writing tool. Pat also shared some of his thoughts about how it could potentially be used to submit assignments through the use of private waves. However although there is potential he did emphasise that we need much more practice to effectively judge the affordances of using it in an educational setting. Although the freedom it gives is attractive in one sense, in an educational setting that freedom could be its undoing.

We then split into groups to discuss each merits of each of the models and do a ‘lite’ swot analysis of each of them. And the result? Well as ever no one model came out on top. Each one had various strengths and weaknesses and a model 6 taking the best bits of each one was proposed by one group. Interestingly, tho’ probably unsurprising, authentication was the most common risk. This did rise to an interesting discussion in my group about the fact that maybe we worry too much about authentication where and why we need it – but that’s a whole other blog post.

Another weakness was the lack of ability to sequence content to learners in spaces like blogs and wikis. Mind you, as a lot of content is fairly linear anyway that might not be too much of a problem for some:-) The view of students was also raised. Although we “in the know” in the learning technology community are chomping at the bit to destroy the last vestiges of the VLE as we know it, we have to remember that lots of students actually like them, don’t have iphones, don’t use RSS, don’t want to have their facebook space invaded by lecturers and value the fact that they can go to one place and find all the stuff related to their course.

We didn’t quite get round to model 5 but the new versions of Sakai and Blackboard seem to be heading in that direction. However, maybe for the rest of us, the next step will be to try being headless for a while.
