  1. Standards, Metadata, Learning Object Repositories, Portals Dr Charles Duncan www.intrallect.com 3 April 2003

  2. Agenda Introduction The future: learning design? Bringing it together UK Organisations Standards Portals Learning object repositories Metadata and beyond

  3. Introduction • Charles Duncan • Senior lecturer, Edinburgh University, 1980-2002 • Project manager of many e-learning projects 1985 – present, including EuroMET winner of European Academic Software Award 1998 • CETIS EC SIG co-chair 2000-2002 • Co-founder and CEO, Intrallect, 2000 –

  4. Intrallect provides • Solutions for Learning Object Management • Strategic consultancy • Software • Bespoke development and customisation

  5. UK Organisations • Schools • Primary (5-12) • Secondary (12-18) • Further Education (FE) Colleges • Vocational (16 + ) • “In work” Training • Universities (Higher Education HE)

  6. Learning and Teaching bodies • JISC1 • CETIS • RDN (Resource Discovery Network) • Regional Centres • LTSN • ILTHE • HESDA (Cooke Report2) • BeCTA • NLN • ALT (SURF) • Others • UKOLN • UK-MEG

  7. CETIS • Centre for Educational Technology Interoperability Standards • IMS, SCORM, CEN/ISSS, etc • News and email discussions • SIGS (coordinated) • Metadata and digital repositories • Pedagogy • Accessibility • Assessment • Educational content

  8. Standards • Why are standards needed? • Sharing • Reuse • Interoperability • Avoid proprietary systems • Promotes new activities (or does it?)

  9. ENTERPRISE METADATA Administration Pedagogy DIGITAL REPOSITORY INTEROPERABILITY Dialogue Collected learning resources LEARNER INFORMATION PROFILES LEARNING DESIGN Vocabulary QUESTION and TEST INTEROPERABILITY COMPETENCY DEFINITION Competencies Delivery system Tests/ assessment Library SIMPLE SEQUENCING Activities Registry/Authority Course IMS Instructor Student

  10. Other bodies • ADL • SCORM • IEEE • LTSC • Learning Object Metadata (LOM)3 • CEN/ISSS • Internationalisation of LOM • ISO and national standards bodies

  11. Metadata and Beyond • IEEE Learning Object Metadata • First e-Learning standard • Application profiles • CanCore, SingCore, UKCMF4 • Internationalisation • CEN/ISSS

  12. IEEE LOM

  13. Application profiles • Mandatory and optional fields • Agreed vocabularies • Agreed use of indentifiers5 • Mapping educational levels6 • Common classification system • Minimise/exclude extensions • What skills are needed for metadata creation?7

  14. Accessibility

  15. Learning Object Repositories • Networked storage of learning objects8 • To promote sharing and reuse • Learning object economy

  16. Digital Repositories are.. • Not portals… • Safe, organised, reliable storage • Not libraries… • Not quite, but good analogy • Many people can put books on the shelves • Not VLEs… • No prescribed pedagogy • Interoperability through standards

  17. Digital Repository Interoperability

  18. Task Search Gather Alert Browse DR Response Expose Object? Metadata? Selected metadata? Priority? Finding objects

  19. Browse

  20. Requesting objects Task • Request • ID? • Unique? DR Response • Deliver • Raw • Streamed • Packaged • Metadata only?

  21. Publishing objects Task • Publish • Metadata? • Deliver • From one repository DR Response • Store • Metadata? • Store • In another repository

  22. Aggregator tool Task • Aggregate • Metadata? DR Response • Deliver • Update Metadata? • Store aggregation

  23. IMS Package College VLE preparing presentations

  24. URL URL

  25. Very useful lesson plan for geography field trips

  26. Roles • Librarian • Contributor • Borrower • Casual user • Administrator • Software Agents • Alert, search, browse, aggregate, deliver, harvest

  27. Some examples • SeSDL: Scottish electronic Staff Development Library • http://www.sesdl.scotcit.ac.uk/ • MERLOT: US and Canada • http://www.merlot.org/ • intraLibrary: • http://www.intrallect.com/

  28. Positioning IntraLibrary IntraLibrary is a Learning Object Management System,which means it : • is a strategic technology which underpins a mixed learning environment9 • improves the management of all learning assets • leads to better quality teaching material with less effort

  29. Current Situation?

  30. Using a LOMS

  31. intraLibrary Demonstration • http://www.intrallect.com/

  32. Portals • One-stop shop?10 • How many? • People change their context • Must be adaptable • by providers • by institutions • by individuals

  33. Resource Discovery Network ? EEVL Humbul ? ?

  34. SOSIG Example

  35. Bringing it together • Key technologies11 • Z39.50 for searching • OAI PMH for exposing metadata • RSS for alerting • OpenURL for resolving “appropriate copy”

  36. JISC Information Environment

  37. The future: Learning Design • Ability to define learning activities12 • Capable of handling collaborative learning • Design independent of implementation • Ability to share and reuse designs

  38. Structure, size and duration of a course are totally determined by teachers course Largest part of MSG-CAL, about 45 minutes long, complex navigation includes sequences and choices module Between 5 and 10 per module, includes specific reference library, external URL and communications groups. Knowledge objects arranged linearly unit-of-study knowledge-object Between 2 and 4 per unit of study. Equivalent to a web page. Usually contains one interaction resource Fundamental resources such as images, animations and video. module module module module module module module module MSG-CAL granularity

  39. Interaction/ problem-solving

  40. Creating new lessons Knowledge objects Units of study Modules
