       What this talk is about
•   Web services
•   Learning networks
•   Connected systems
•   Web 2.0
•   The e-Framework
1. Some background
       Connected=better?
• People obtain benefits from being
  connected into networks and
  communities
• Systems connected into networks and
  meta-systems gain benefits not
  available to isolated systems
• Metcalfe‟s Law
  Connecting with pedagogy
• Six degrees - social networks - COPs
• Connectivism - the network is the
  learning
• PLE - placing the learner at the centre
  of the network
            Connections
• The internet is all about connections
• Connections can be made that break
  out of hierarchies (trees) and enable
  overlapping semilattice structures
• Overlaps and fuzzy boundaries are
  characteristic of „natural‟ or „open‟
  systems
              1+1=3?
• When you combine the features of two
  systems, you can get unexpected
  synergies

                  More
• Postgenomic - mixing weblogs and
  folksonomies with traditional research
  papers
  – http://www.postgenomic.com
• Delicious library - mixing the desktop
  library and the online book store
• 43Things, 43Places, 43People…
3. technology
     Where does the magic
          happen?
• As well as the web for humans, there is
  an increasingly large web for machines,
  too
• It talks the same protocol (HTTP) as the
  more visible web, but uses dialects of
  XML (or RDF) instead of HTML
           Web Services
• A web service is when someone
  provides a service on the web for
  machines as well as (or instead of) for
  people
• The most common type is a feed - an
  XML representation of a list of posts,
  media (podcast), or news
Apple desktop widgets using web service APIs
                   Feeds
• Feeds are useful educationally as they are an
  attenuation device: they reduce the variety of
  the network to a selection of important
  sources
• We can then mix, sort, group, rate and
  annotate the resources
• Feeds aren‟t just for resources, the same
  basic technology is also used for people
  (FOAF) and events (iCalendar)
     Other types of services
• Other services enable the creation or
  modification of resources rather than
  just getting alternative representations
• These we (in the PLE project) tend to
  call “conduits”
• For example, there is a standard
  protocol for posting a new entry in a
  weblog
              Conduits
• Conduits are extremely useful as they
  provide a feed-forward mechanism - we
  can share our mixes with others
• It also means we can separate hosting
  from authoring, something taken
  advantage of by a huge range of
  desktop weblog clients
                Discovery
• Feeds tend to be advertised on sites using
  common icons
• There are also tags in HTML that can be
  used to automatically find associated feeds
• Complete sets of services (APIs) often have
  their own page on a site with descriptions of
  how to use them
4. education
  Educational Web Services
• Feeds and conduits are increasingly
  common on the web, but are there any
  specific things we‟d like in education?
• For example, what about being able to
  get feeds of courses rather than
  articles? Or post an essay for marking
  rather than a post?
       There are quite a lot…
•   Enrollment (who‟s on what course)
•   Reading lists
•   Timetables
•   Curriculum/prospectus
•   Portfolios
•   Learning designs/activities
      Enter the e-Framework
• A collaborative effort by JISC, DEST, SURF,
  NZ MoE and others to make sense of web
  services in education
• Identifying the possible kinds of services, and
  try out solutions, help implementers, and
  agree specifications
• Also looking at identifying services in
  common with other domains in education, like
  research and administration
        Reference models
• Envisaging how services can be
  combined to support an educational
  process or address an area of concern
• Assessment, portfolios, personal
  learning, learning activities, course
  validation, curriculum management…
