Overview of Presentation
  • Initial project scenarios (COLIS IMS DR)
  • Industry partner scoping, and Phase 1/2
    discussion
  • Broader IMS context for Phase 1
  • Finalised Phase 1 scenarios
  • Some areas for further consideration from Phase 1
  • So what are Learning Objects anyway?
  • Personal reflections on a new conceptual approach

3
Initial Project Scenarios
  • Key points
  • Standards-based interoperability using IMS
  • Multi-vendor Demonstrator environment
  • No single dominant player
  • Integrate both online learning AND information
    systems
  • Implement Learning Objects with digital rights
    management
  • Modest budget

Industry Partner Scoping
  • Initial partner scoping done individually, then
    iterative development based on shared scenarios
  • Main challenges
  • Finding a common language/shared definitions
  • Finding a common global use case
  • Integrating online learning and library
    worldviews
  • Understanding the full implications of DRM
  • Implementing a Single Sign On (SSO) approach
  • Refining Phase 1 versus Phase 2 targets

Broader IMS context
  • During COLIS Phase 1 scoping, IMS held a major
    review of their current standards (April)
  • Experienced similar challenges to COLIS
  • Finding a common language and use cases
  • Dealing with standards which cut across system
    functionality (and each other), eg, SS, LD, Acc
    DRM
  • Recognising different needs for standards based
    on data interchange versus run-time behaviour
  • Other challenges included current standards
    harmonisation, and the lack of a glue standard

9
Broader IMS context
  • Some proposed solutions?
  • Disaggregation of Learning System components
  • Layered system architecture
  • Proposal for development of a new content model
    to assist in harmonising current content
    standards
  • Greater focus on use cases (especially global
    use cases)
  • The OKI approach

Broader IMS context
  • As part of the Boston IMS meeting, I attempted a
    Global use case loosely based on COLIS
  • Incorporation of different actors stages in the
    process
  • Tried to match current IMS specs against the
    different requirements of higher education
    corporate learning
  • Considered missing elements of IMS specs (eg,
    DRM)
  • Offered a very vague percentage complete figure
    to try to gauge how far IMS had got with each
    area
  • Broadly helpful, but some didnt agree with the

Finalised COLIS Phase 1 Scenarios
  • All actions to take place within SSO environment
  • Teacher actions
  • Search for LO in LOX, accept licence terms,
    download
  • Upload LO to LCMS, manage LOs, prepare for LMS
  • Use federated search gateway for search of
    meta-data
  • Create link to LOs in LMS course area
  • Student actions
  • Login to LMS, go to relevant course, access link
    to LOs
  • LCMS processes licence requirements student
    details
  • (1) Present LO, (2) Present usage agreement, or
    (3) Deny access
  • Track student access to LOs against licence
    limitations

Some Areas for Further Consideration
  • Authoring Learning Objects already identified as
    out of scope for Phase 1
  • IMS COLIS Use Case identified additional areas
  • Prescribing of learning requirements by authority
  • Designing and implementing assessments
  • Recording of assessment outcomes for authority
  • Various technical challenges moved to Phase 2

Some Areas for Further Consideration
  • Concept of Learning Objects remains very
    content-centric, not learning
    activity-centric
  • Where does the use of learning tools and
    collaboration fit within a Learning Objects
    approach?
  • How do we describe learning in a multi-student
    environment in a standards-oriented way?

So what are Learning Objects anyway?
  • NB Personal reflections - not a COLIS view
  • Considerable confusion over the meaning of the
    term Learning Object
  • Meaning tends to be used very broadly, eg
  • (1) Individual files (text, image, movie, etc)
  • (2) Individual files with meta-data
  • (3) Sets of files (with or without meta-data)
  • (4) Combinations of files and activities (eg,
    content formative assessments)
  • (5) Whole courses containing content and use of
    LMS tools

22
So what are Learning Objects anyway?
  • Use of XML is considered central to Learning
    Objects, but it can be used for very different
    purposes
  • XML for data interchange (search retrieval,
    transport)
  • XML to separate content from presentation
    (alternative rendering into Web, Print, PDA,
    etc)
  • Learning Content Management System is the term
    used to describe LO-driven systems
  • But, very different system requirements depending
    on which concept of XML is used
  • IMS predominantly data interchange XML to date

23
So what are Learning Objects anyway?
  • A new conceptual approach
  • Three layers Learning Activities
    (highest) Learning Objects Digital Assets
  • Definition A Learning Object is an aggregation
    of one or more digital assets, incorporating
    meta-data, which represent an educationally
    meaningful stand-alone unit
  • In practice, a Learning Object will often be
    identifiable with a specific Learning
    Outcome/Objective
  • Different technology tools and standards apply to
    each of the three layers

25
So what are Learning Objects anyway?
  • Definition A Learning Object is an aggregation
    of one or more digital assets, incorporating
    meta-data, which represent an educationally
    meaningful stand-alone unit
  • A collection of two or more Learning Objects can
    be called a Learning Object Sequence
  • A collection of two or more Learning Activities
    can be called a Learning Activity Sequence
  • Re-usability should exist at all levels Digital
