One man and his spreadsheet, a gephi wizard and the voice of reason

Is how I would sum up the speakers at the Social Network Analysis session at #cetis12.

I started the session by giving a very brief overview of SNA and tried to highlight why I think it is important, particularly to an organisation such as CETIS, who stakes quite a bit of of its reputation on its ability to network (see this post for some more of my thoughts around this). Using SNA we are now able to actually see and share our existing connections and, potentially any gaps.

I am always inspired by (and slightly in awe of) the work of both Tony and Martin in visualising communities, however I am always aware of the skills gap between their levels of competency and my own. So, I also wanted to raise the issue of “just in time/just enough” tools. Sometimes a quick snap shot of activity is really effective and all that’s needed. There’s also the issue of interpretation and common understandings.

Whilst visualisations can in many cases illustrate complex connections more eloquently than words, there are also cases, particularly around more complex visualisations where some common understandings of the models being used to create the visualisations and the data sources are required. A case in point was Adam Cooper’s opening presentation at the conference where he showed some examples of text mining and analysis of CETIS blog post. This provoked quite a bit of chin stroking twitter back-channel activity. I think this illustrats some of potential dangers around presenting what can appear to be an objective view of things which is based on subjective data. As I knew more about the data Adam’s presentation raised lots of really interesting questions for me, but another danger of social media is that twitter is often not the best medium to have an informed discussion.

Martin Hawskey’s (a man quite possibly on a mission to take over the world via google spreadsheets) presentation opened up the session from just SNA to a wider data discussion by highlighting some examples of data journalism, which have very effectively combined visualisation techniques and contextualisation. Martin then took us through some of the work he has recently been doing for JISC and CETIS in visualising activity around the UK OER projects.

Tony Hirst, aka the gephi wizard, then gave us a masterclass on data visualisation techniques, showing us how visualisations can provide “at a glance or macroscopic” views of huge datasets; which he encapsulated by the d3i model – data,information, intelligence, insight. As well as a sharing variety of examples from MPs expenses to Formula 1 racing to Brian Kelly, Tony has also been working with Alan Cann (University of Leicester) to visualise connections between students using Google+. Unfortunately Alan couldn’t be attend the session in person but he did share this video about their work. I’m looking forward to hearing more about this use of SNA in a real teaching and learning context.

Amber Thomas followed with a very balanced presentation “Lies, damed lies and pretty pictures” which gave a very balanced and but still thought provoking view on how we should be thinking about using the network and data analysis techniques. My colleague David Sherlock has blogged some thoughts on Amber’s presentation too. Amber highlighted some key tactics which included:
*reducing our fear of numbers
*being generous with our data ( and remembering who actually owns the data)
*combining data and effort to work faster /more effectively across the sector

We then had some live analysis of data being driven via the conference #cetis12 hashtag – again what one man can do with a spreadsheet is quite amazing! You can see the results in the CETIS 12 TAGSExplorer.

App Stores Galore at #cetis12

Over the last two months, The Open University, the University of Bolton, KU Leuven, and IMC, with funding from JISC, have been working to develop a Widget Store aimed at the UK education sector using a codebase shared across and sustained by a range of other EU projects and consortia. (see Scott’s post for more details on the technical work and getting involved).

The Creating and Education App Store for the UK session at the CETIS conference, was the first opportunity for the team to share, firstly the vision of a shared codebase to underpin a range of existing and potential widget stores. And secondly, to share initial prototypes of UIs, and get feedback on the work to date and potential future development ideas from delegates.

Fridolin Wild (OU) gave a useful overview presentation “the university in a box” which highlighted the work of the OU in various widget related projects and initiatives which have built on the notion of the personalised learning environment.

Scott Wilson, (University of Bolton/CETIS) then set the wider context of widget developments, from W3C o the JISC DVLE programme, which is neatly encapsulated in the diagram below.

One of the key parts of the work is to provide extended community building features such as ratings, comments, use cases etc. As well as providing additional support for users of the store(s), Scott also outlined plans to share this “paradata” via the JLeRN Learning Registry node (which was discussed as part of a parallel conference session).

Over the 3 hour session there was much discussion around three key areas:

1. Institutional use of such a store: e.g. how would you use such a store? Have a local installation or use a hosted services? Implement connectors using IMS LTI for example.

2. Tracking and Recommendation services: what would be captured? how would it be shared? How could useful analytics be captured and used?

3. Widget Authoring: led by the Widgat team a useful discussion centred around their widget authoring tool.

For the conference plenary a two slide summary was produced, and look out for more details on the store over the coming months on this blog.
