Personalisation is the supply of services and/or data based on a model of a user

As part of work commissioned by JISC from Sero Consulting and Hedtek I’ve come up with a broad, simple definition of personalisation:

Personalisation is the supply of services and/or data based on a model of a user.

Supply and model are interpreted broadly, to mean by a machine or human agent. Examples of human agency are personalised shopping, by one person for another,  and self-regulated learning, by someone for him/herself.

Achieving the impossible

Increasingly austere times are upon us, and despite a degree of ring-fencing of the education budget after the 2010 election, the future for education in the UK looks increasingly grim. Today we see further confirmation of a rumour in HE circles, that there looks likely to be a large cut in Higher Education funding in the near future. Yet to rebuild the wealth of the nation, we need to radically improve the quality of our workforce. This depends on the education, not only of the current workforce, but also of future recruits.

Not only do we have to deal with future fiscal constraints, but we also have to deal with a future in a world that is characterised by ever-increasing change and consequent levels of uncertainty. We need the ability to both learn in changing environments, and to apply the results of that learning in those changing environments.

UK learning practice suffers from systemic problems in the school education system that are centered around teachers being forced to produce students who can pass tests and exams. While doing well is not wrong, the by product of this kind of education is that children loose their natural curiosity and instead become set in a pattern of doing the minimum that they think is needed to achieve a desired grade, most often by simply reactively doing what they are told to do by a teacher. By the time learners enter HE they are fully habituated to this pattern, and most often HE only further institutionalises the problem.

Instead, we should be interested in the construction of a personally relevant learning experience for each and every learner, such that learners gain characteristics that are useful in, and lead to, social, cultural and economic development.

And while we value the existing utility provided by learning support systems, we note that they fall far short of the mark in supporting this kind of education particularly on the level of the national massification that we need. In fact, learning support systems are themselves incapable (for the forseeable future, at least) incapable of supplying this kind of education.

Could teachers and lecturers instead supply these personally relevant and meaningful learning experiences? Diana Laurillard, in her inaugural professorial lecture at the Institute of Education, points to the impossibility of teachers on their own supplying a personalised learning experience.[1] Indeed, the impossibility of supplying learners with personalised learning experiences is, in general, a self-evident truth to those of us who work in the education sector.

The only course that remains, then, is for learners to construct these learning experiences for themselves. In fact, self-directed learning is the only economically feasible means of providing a personalised and meaningful learning experience on any kind of massified scale.

What does it mean to be a self-directed learner? Essentially a self-directed (or ‘self-regulated’) learner takes control of his or her own learning, and in the process performs various metacognitive activities that involve thinking about their learning. For example, a learner might set learning goals, and then perform, monitor, replan, etc their learning activities, possibly changing their overall or intermediate learning goals in the light of ongoing learning performance and newly gained knowledge. It is hard to divorce this view of learning from learning together with other learners: Learners will learn best when applying self-directed learning as part of a group of learners who are assisting each other in learning together.

While this sounds radical in terms of the staus quo, it is important to note that the central aspects of institutional education – syllabi, assessment and formally appointed teachers – are all eminently possible within the approach. We do however recommend that the nature of assessment changes to formatively support the processes of learning and learning to be a self-directed learner.

Where is the support for socio-economic change mentioned in the first paragraph?

“Self-management of thinking, effort, and affect promotes flexible approaches to problem-solving that are adaptive, persistent, self-controlled, strategic, and goal-oriented.” [2]

These are precisely the skills that we need to deal with a changing world: Experience gained in learning within changing knowledge landscapes will create persistent transferrable skills that underpin life long learning, and life long learning skills are essential to enact the kind of change we need.

So specifically there is a proposal here, that we have to transform the learning practices of learners in higher education. This is a vast pedagogic shift that is bound to hit innumerable barriers, but one that, I posit, is inevitable if we are to successfully deal with real-world constraints on education and at the same time transform our longer-term socio-economic prospects.

So how do Personal Learning Environments (PLEs) fit into this? Whatever the brouhaha about what a PLE is, the thing that underpins and unifies the PLE movement is that it is about learners doing it for themselves; learners taking control of, directing and managing their own learning. A PLE provides the infrastructure for that kind of learning. Of course, infrastructure is only part of the solution; the other part is achieving the pedagogic revolution. This relies on students unlearning their current learning practices and adopting new practices in a guided and supported fashion.  Sometimes I privately refer to this as “achieving the impossible” when considered across the HE sector, or even within a unit as small as a three-year degree programme. There are profound impediments to achieving this that are rooted in institutional culture and practice.

But despite the barriers and my sometimes thoughts “impossibility”  I remain an optimist; there seem to be two approaches that may pay dividends. Firstly a grass roots  approach of individual university  departments committedly adopting an approach to self-directed learning and working towards this goal over several years, concentrating initially on key steps to change student learning culture. Secondly, there is a more formal funded cross-institutional approach where one could imagine a programme that plans and delivers roll-outs of materials, methods and pedagogy produced by early adopters, feeding back into the programme experience from both adopters and adoption/roll-out processes.  Neither approach provides an easy path, but given that pressures on education seem to increase unabated, the right drivers for these approaches may have arrived. And while these are likely  long-term activities where there would likely be no short-term effect on the current economic climate, I fully believe that such a programme would have profound positive implications for our national future.

Project award: fishDelish

We are very pleased to have a strong role in the fishDelish Project awarded to the  University of Manchester’s School of Computer Science by the Joint Information Systems Council (JISC). Our co-partners in the project include FIN Inc, a not-for profit NGO that has created and runs FishBase, a 400M hit per annum species-specific database.

The project is aimed at three targets:

  1. Putting a large portion of Fishbase’s relational data on the web as Linked Data triples. We anticipate, during the next nine months, putting more than 100M triples on the web. This has its own challenges, eg converting the relations we are generating (using R2D) with existing standards, making sure that copyright information is maintained, and not least of all, dealing with a large data-set.
  2. Building basic species pages from linked data, and providing a self publishing mechanism for collection and aquarium data
  3. Adding a live tutorial medium for SPARQL based on our open source iDoc documentation product

This project has been running for about a month, and we are making good progress with data conversion and have already constructed basic species tables from data in a triple store (we are using 4store with a custom Ruby on Rails front end for this).

The fishBase team consists of Bijan Parsia (UofM SCSc), Sean Bechhofer (UofM SCSc), Rainer Froese (IFM-GEOMAR and FIN Inc), Dave Workman (Hedtek) and Mark van Harmelen (Hedtek and UofM SCSc).

iDoc: Hedtek’s open source community documentation system

iDoc screenshot

iDoc is an open source community documentation system for the production and use of help documentation for web sites and applications. It’s more than just a vanilla documentation system:  We believe is important is for the users of an application to be able to contribute back and help others learn to use an application application — iDoc allows this by allowing users to sign up and comment on help pages. It is also possible to set iDoc to allow any user to create or edit help pages, indeed, this is currently the default behaviour!

What we’ve been doing at Hedtek

Our last post was way back, during ALT-C. Since then we’ve been totally heads down, working on projects for clients and on our own PLE Project.

The JISC-funded MOSAIC Project, with SERO and co-partners Ken Chad (Ken Chad Consulting) and Paul Miller (Cloud of Data) investigated, at many levels, a new social and personal search approach to library catalogues for learners. This breaks new ground, by providing social search facilities based on attention data that is encapsulated in library loan information. The project and the prototype we provided produced some really good outcomes, with JISC promoting the outputs in various meetings, and commissioning a bit of further work to see how the MOSAIC search approach can be progressed in UK Higher Education. You can try our prototype at mosaic.hedtek.com (this will move to http://demo.mosaic.hedtek.com and I’ll edit this post and remove this comment then).

The iCue project also produced interesting and useful results for client Mimas. We were tasked with the development of an algorithm to help structure the 70M record Copac database, which contains details of the the holdings of some +/-40 UK university libraries. The end aim was to provide a better search experience for Copac users. The standard way of doing this is to use a scheme based on the Functional Requirements for Bibliographic Records (FRBR) approach. Using a three level FRBR approach (such as e.g. used by WorldCat Local)  we developed a FRBRisation algorithm, prototyped and refined it, and provided a first level mockup of structured search facilities.

We’ve also been working hard at improving the Manchester Personal Learning Environment (the Manchester PLE). Last September I used it to support my Interactive System Design course (with a cohort of 80 students attending the University of Manchester ‘s MSc in Advanced Computer Science). This threw up some bugs and identified a lack of support for teachers when the PLE is used in an institutional setting. We fixed the bugs, performed some code refactoring, vastly improved the user interface, and added support for teachers by providing any PLE suer with the ability to set a blog based assignment. Friends Sefol re-implemented the spaces for us, concentrating on reliability. Finally we feel we are ready for a public release.

Dave also implemented the marvelous iDoc system for the Manchester PLE, where we are going to mostly use it to host short (much less than a minute) help videos. iDoc is designed for user generation of help information, and for user comments on that help information. It can also be restricted to ‘expert’ named users writing the main body of the documentation, with others adding the comments only. It can be used with any application, particularly where the authors of that application want help buttons to deep link to particular help information. If you don’t know what deep linking is, the effect is to click a help button for xyz while trying to do xyz, and being taken directly to the help for xyz. But once you’re there, you can browse around the other help information. We’ve decided to open source iDoc. This text will become a link to a post to iDoc.

iDoc was our first venture into Behavior Driven Design (BDD). And, from an engineering point of view, the experience was massively successful. We’ll post on that later. Dave open sourced a ruby gem in the process. We did two of four planned iterations, so there are still additions to come to iDoc. However its eminently usable now, and we have, bar the the copyright notices, an Open Source product in iDoc. Try it out at  demo.idoc.hedtek.com, and get the source via source.idoc.hedtek.com. (Both coming soon, I’ll remove this bracketed comment when these links go live.).

PLE Conference – Barcelona July 2010

Barcelona crest

Advance notice of The PLE Conference, Barcelona 8-9 June July 2010.

From an e-mail from Graham Attwell, with a mild edit:

The PLE Conference is intended to produce a space for researchers and practitioners to exchange ideas, experience and research around the development and implementation of PLEs; including the design of environments, and sociological and educational issues and their effectiveness and desirability as (informal) learning spaces.

Whilst the conference will include a traditional research paper strand, we also wish to encourage proposals for sessions in different formats including workshops, posters, debates, cafe sessions, hands on sessions and demonstrations. We will also provide opportunities for unconferencing events, including the provision of spaces for informal meetings and discussions.

The face-to-face conference will take place in the Open Innovation Centre for the Community in Barcelona. The Centre located in a converted factory, and provides a variety of purpose designed spaces for exchanging ideas, including an auditorium, meeting rooms and spaces for informal discussions.

The centre is well equipped with multi-media equipment, and there will be free access to a fast wireless network throughout the venue.

The conference will utilise multiple on-line spaces including a web site, a social networking space for participants, and other social software.

Conference themes include (but are not limited to):

  • Theories and frameworks for Personal Learning Environments
  • Technologies and software for developing Personal Learning Environments
  • PLEs in Practice (case studies, approaches to using PLEs)
  • Educational institutions, change and PLEs
  • Pedagogical approaches to managing personal learning
  • The development and management of Personal Learning Networks
  • Mobile PLEs and augmented reality
  • Supporting informal and and contextual learning
  • Using PLEs in organisations
  • Using PLEs for work-based learning

The conference organisers will shortly be launching the conference web site and issuing a call for contributions.

Hedtek tumblelog

For the last year we’ve been a bit inward facing with several large projects to attend closely to, including getting the PLE to a usable state, and running the first trial with 80 users. This blog has been pretty much focused on company stuff, on presentations I’ve made, and on the Manchester PLE.

Wanting something a bit more lightweight, with a bit more of a personal touch, I’ve established a tumblelog of over at hedtek.tumblr.com. Who knows how it will evolve, but right now it seems just right for stuff we like, with a dash of tek sauce.

The Mosaic search engine

 
We are coming to the end of the JISC-funded Mosaic Project. As part of that project Hedtek has designed and, with help from our friends at Sefol U.G., implemented a prototype search engine that allows personalised searches of bibliographic data according to one’s own course cohort, or according to various other faceted criteria that allow the adoption of various points-of-view.

Various resources pertaining to Hedtek’s Mosaic search engine appear here:

  • Slides from the Mosaic meeting on 18 November 2009. (Other slides from the meeting)
  • A brief description of the search engine and its use
  • The search engine URL (at the end of this post)

Slides

A brief description of the Mosaic search engine

The Mosaic search engine is a demonstrator that was developed by Hedtek as part of the JISC MOSAIC Project. The search engine is a proof of concept investigation of the potential of user attention data (in the form of library circulation data), the ability to find library items that pertain to ones own context, or, browsing around , the ability to adopt other personas and see what pertains to them.

The purpose of the demonstrator was to assess

  • If we could construct a search engine that supplied personalisation facilities around a particular kind of attention data, library loan records
  • If we could thereby leverage the users context, in this case where they were in the university system (university, course, progression level)
  • The feasibility of basing this on the Lucene/Solr, and the way in which the index data would need to be constructed and used.
  • Possible query and display interfaces
  • Data anonymisation processes
  • The sense and value of the intelligence to real users (to be exploited more fully in workshops in Oct / Nov 2009)

Ultimately we would expect the model to support

  • Reading lists
  • Use records derived from library circulation/loan systems (LMSs)
  • Use records derived from virtual learning environments (VLEs)
  • OpenURL resolver / ERM derived information
  • Search histories
  • Searcher location
  • Searcher preferences for particular kinds of results

Two kinds of results are supplied by the demonstrator:

  • Normal un-personalised search, with no facets selected (results with light blue backgrounds)
  • Faceted search (1-4 facets selected) that define points of view, eg personalised for me, for third years at Oxford, for me if I was in the year above, for PhD’s in my subject, this year, last year, etc. (here the relevant results for the persona selected appear with a dark blue background, other results with a light blue background).

Two interfaces are supplied to do the persona adoption

  • A Classic faceted shopping interface
  • An iTunes browser-like interface

Because we were aware that the faceting might sometimes result in a narrowing of choice, we supplied two mechanisms to broaden choice

  • A results like this link for each result, that invokes a search based on the results title (and is surprisingly effective)
  • The incorporation of reading list information, supplying the complete reading list if a search result is on that reading list.

The demonstrator contains only LMS Circulation and Reading List data. It combines the COPAC monographs database with three years of usage data from the University of Huddersfield. Not all titles are therefore linked to use data.

The data has been ‘doctored’ in 3 ways

  • Split in to 5 fictitious universities
  • Example reading lists inserted to illustrate how they might be integrated
  • Links made from the Title display to the JISC EIE project ‘compositor’ to display further details and provide opportunity for contribution

The interface implemented here searches only authors and/or titles and then allows the results to be refined using any combination of four facets

  • Institution
  • Progression level (plus a staff ‘level’)
  • Course
  • Academic year in which the loan was made

Results are returned for almost any keyword combination search – but not always linked to use data (that’s the real world). To see use data, which is displayed in the four ‘facet’ lists, try searching for

  • Accountancy
  • Economics
  • Medical

To pick up reading list records as well as use data, try searching for

  • medical law

and click on the reading list icons.

Try it!
