  1. Extending Educational Metadata Schemas to Describe Adaptive Learning Resources Cord Hockemeyer Owen Conlan Paul Lefrere Vincent Wade Dietrich Albert

  2. Overview • Background of the work presented • A basic generic metadata element describing different types of adaptivity • An extended adaptivitytype element • Summary

  3. Background: The EASEL Project

  4. Interface Standards Involved • Learning Environment – Adaptive Content • AICC CMI • SCORM API • ContentDescriptions through Metadata • IEEE LTSC LOM • IMS (Learning Resources) Metadata • DC ed

  5. A Generic Adaptivity Element education? adaptivity? adaptivitytype* name=<langstring> ref=<URI>? langstring*

  6. Example <adaptivitytype name=“specialneeds“> <langstring lang=“en“> Visual Disability </langstring></adaptivitytype> <adaptivitytype name=“competencies.required“ ref=“some-URI“> <langstring lang=“en“> Database concepts </langstring></adaptivitytype>

  7. Best Practice Lists forAdaptivitytype Names • Compatibility of adaptivity information • Acceptance through comprehensive list • Hierarchical structure for shared vocabularies

  8. Vocabularies • Vocabulary used within adaptivitytype content depends on subject and on pedagogical models • Common vocabulary is a prerequisite for interoperability • Possibility to use specialised vocabularies

  9. An Extended Adaptivity Element adaptivitytype* name=<langstring> ref=<URI>? set? type=“one-or-more“|“all“|... set* candidate* langstring*

  10. Example <adaptivitytype name=“competencies.required“><set type=“one-or-all“> <set type=“all“> <candidate> <langstring lang=“en“>compA</langstring> <langstring lang=“de“>KompA</langstring> </candidate> <candidate> ... </candidate> ... </set> <set type=“all“> ... </set> ...</set> </adaptivitytype>

  11. Summary The suggested generic metadata element fordescribing adaptive learning objects is: • suitable for many different types and mechanisms of adaptivity • applicable for structured information • flexible with respect to vocabularies
