Story telling with Data

February 18th, 2011 by Graham Attwell

Today Google Labs released their new data visualisation store. Very impressive it is too, although it is not a straightforward task to register on the site, upload uses an XML format and you cannot download data. But the visualisation is pretty good and Google themselves have linked to a number of large Eurostat data sets.

I have been working on data for the last couple of weeks. I am trying to build a TEBO – a Technology Enhanced Boundary Object (or objects) for explaining Labour Market data to Careers Advice, Information and Guidance (CAIG). Together with my colleagues from the Institute for Employment Research at Warwick University, I have been looking at TEBOs for some time.

Alan Brown explains the conceptual idea behind TEBOs:

The ideas of boundary crossing and tool mediation (Tuomi-Gröhn & Engeström, 2003; Kaptelinin & Miettinen 2005) and situated learning with a close alignment to the importance of a focus upon practice (Brown et al., 1989; Hall, 1996) informed considerations of the role of technologically-enhanced boundary objects in knowledge maturing processes in different contexts. One specific concern is to make visible the epistemological role of symbolic boundary objects in situations in which people from different communities use common artefacts in communication. A fruitful approach to choosing ways to develop particular boundary objects is to focus on what Onstenk (1997) defines as core problems: the problems and dilemmas that are central to the practice of an occupation that have significance both for individual and organisational performance — in this case the problems associated with providing advice relevant for career planning. One method this development project used was therefore to engage in a dialogue with guidance practitioners about common scenarios involving Labour Market Information (LMI) which could inform the development of prototype technologically-enhanced boundary objects (TEBOs). The development … was therefore informed by a consideration of the following issues:

  • Importance of developing methods and strategies for co-design with users
  • Need for conceptual tools to help people understand the models and ideas which are part of LMI
  • Need for a more open pedagogy (than is typical of much existing technology-enhanced learning, and existing workplace training practice)
  • A system in which boundary objects are configurable by end-users (practitioners) and by guidance trainers to be used in multiple ways
  • Need to build an understanding of how TEBOs may be used in ways that are empowering for practitioners, and ultimately for clients too.

These concerns could be coupled with another set of issues concerning appropriate skill development:

  • Need for time for people to interact, reflect, use concepts etc.
  • Trying to reach a stage where practitioners have justifiable confidence in the claims they make and can exercise judgement about the value of information when faced with unfamiliar LMI
  • Choosing between a range of possible use-contexts
  • Decide how to employ support from communication and discussion tools
  • Developing and transmitting Labour Market intelligence – importance of communicating to others
  • Preconfigure certain ways of thinking through use of scenarios; discussions can point into and lead from scenarios.

In practice it is not so easy to develop such TEBOs. Identifying key problmes is probably the most useful approach. But then there is an issue in accessing different data to visualise as part of the process. A great deal of data is now publicly available. But I am no data specialist and have faced a steep learning curve in understanding and interpreting the data myself. then there is the issue of visualisation – I am mainly using Google Gadgets, although we are also working with Tableau (a powerful tool, but unfortunately only available for Windows) and IBM;s Many Eyes. All these tools are good, but are all extremely finicky about how the data is formatted. We are working with data in xls and Apple’s Numbers but I suspect longer term it would be better to use the Open Source R programming environment.

And the hardest task of all is the storyboarding. At the end of the day we are trying to tell stories with data: TEBOs are a storytelling and exploration approach to learning. So for each TEBO I intend to make a short video explaining the key concepts and showing the various visualizations. We will also provide access to the raw data and to static versions of the graphing, along with explanatory notes. And for each TEBO we will try to construct an interactive visualisation tool, allowing learners to play with the data and displays. I also want to try to build some sort of simulations using the Forio tool. No doubt there is better software (and if anyone has any ideas I would be very grateful). But I sort of feel that the more social software, open source or free tools we can use the better. We want to encourage people to do it for themselves. And they have no money to spend on fancy software tools.We cannot possibly provide access to visualisations of all the data available. But if we cane explain what is possible, hopefully interested CAIG professionals will start there own work. And then who knows – a Careers Guidance data store?

    Hey,
    have a look at Gephi at http://gephi.org/users/download/. They claim to be “Like Photoshop for graphs”

    Thanks for the tip concerning Googles visualization store, I had not noticed that they had opened it.
    I have been using Google Fusion Tables, it’s very easy to get data in and out but the visualizations are a little bit limited. But at least there is a basic version of the Gapminder (moving bubbles) visualization tool, which is nice. The Google maps mashup tool is also very useful. I have embedded a few experiments here: http://romirancken.net/.

    For simulations I have been using the free Vensim tool (http://vensim.com/) for many years, it’s a good simulation tool, but it is not as eye-catching as some of the newer tools. The basics are easy to learn, you get a grip of the essential functions in an hour, based on my experience with students. And there is a Mac version too 🙂

    Cheers,

    Romi Rancken

    Cyborg patented?

    Forbes reports that Microsoft has obtained a patent for a “conversational chatbot of a specific person” created from images, recordings, participation in social networks, emails, letters, etc., coupled with the possible generation of a 2D or 3D model of the person.

    Racial bias in algorithms

    From the UK Open Data Institute’s Week in Data newsletter

    This week, Twitter apologised for racial bias within its image-cropping algorithm. The feature is designed to automatically crop images to highlight focal points – including faces. But, Twitter users discovered that, in practice, white faces were focused on, and black faces were cropped out. And, Twitter isn’t the only platform struggling with its algorithm – YouTube has also announced plans to bring back higher levels of human moderation for removing content, after its AI-centred approach resulted in over-censorship, with videos being removed at far higher rates than with human moderators.

    Gap between rich and poor university students widest for 12 years

    Via The Canary.

    The gap between poor students and their more affluent peers attending university has widened to its largest point for 12 years, according to data published by the Department for Education (DfE).

    Better-off pupils are significantly more likely to go to university than their more disadvantaged peers. And the gap between the two groups – 18.8 percentage points – is the widest it’s been since 2006/07.

    The latest statistics show that 26.3% of pupils eligible for FSMs went on to university in 2018/19, compared with 45.1% of those who did not receive free meals. Only 12.7% of white British males who were eligible for FSMs went to university by the age of 19. The progression rate has fallen slightly for the first time since 2011/12, according to the DfE analysis.

    Quality Training

    From Raconteur. A recent report by global learning consultancy Kineo examined the learning intentions of 8,000 employees across 13 different industries. It found a huge gap between the quality of training offered and the needs of employees. Of those surveyed, 85 per cent said they , with only 16 per cent of employees finding the learning programmes offered by their employers effective.
