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= ref= ? langstring*

6. Example Visual Disability Database concepts

7. Best Practice Lists for Adaptivitytype 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

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