  • Strijker, A. (2002). Teletop Techniek En Didactiek

    1. 1. e-Learning, from concept to practice Re-use of material Standards
    2. 2. Why Creating Material <ul><li>Web environment for part time students Wide scale implementation </li></ul><ul><li>Resources are growing fast </li></ul><ul><li>Teachers started creating resources </li></ul><ul><li>University level </li></ul><ul><ul><li>1600 courses </li></ul></ul><ul><ul><li>50 - 300 objects in every course </li></ul></ul><ul><ul><li>With a average of 100 objects a course, this is 160.000 objects </li></ul></ul><ul><ul><li>More then 10.000 users </li></ul></ul>
    3. 3. Reuse of Material <ul><li>Partly reuse of old courses </li></ul><ul><li>Teachers created resources themselves </li></ul><ul><li>Update resources where necessary </li></ul><ul><li>Removed out of date resources </li></ul><ul><li>Why differ from “old” HTML based courses? </li></ul><ul><ul><li>Ease of use </li></ul></ul><ul><ul><li>Generated links </li></ul></ul><ul><ul><li>Teacher “controls” the content </li></ul></ul>
    4. 4. Content <ul><li>Combination of material </li></ul><ul><ul><li>Data </li></ul></ul><ul><ul><li>Metadata </li></ul></ul><ul><ul><li>& (not always) Attachments </li></ul></ul><ul><ul><ul><li>Video </li></ul></ul></ul><ul><ul><ul><li>Applets </li></ul></ul></ul><ul><ul><ul><li>Flash animations </li></ul></ul></ul><ul><ul><ul><li>MS docs </li></ul></ul></ul><ul><ul><ul><ul><li>Powerpoint </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Word </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Excel </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Plaatjes </li></ul></ul></ul></ul>
    5. 5. Units of Learning Material (ULM) <ul><li>Objects, documents, records in the database, digital content, Also Assignable units (AU) or Shareble Content Object (SCO) </li></ul><ul><ul><li>“ a ULM is an abstraction which collects a variety of segments of learning material based on different media and featuring different layouts, languages and encoding types, with their differences concealed to offer a common and consistent interface to it’s clients. A Ulm may be a simple monomedia object or a composition in space time (layout) of several pieces of learning material; its multimedia message to the user possibily includes texts, still frames, dynamic sequences and digital audio “ </li></ul></ul>
    6. 6. TeleTOP Environment
    7. 7. Creating Content
    8. 8. Course Content
    9. 9. Direct copy Re-use content content content
    10. 10. Larger Scale of Reuse <ul><li>Exchangeability </li></ul><ul><ul><li>Other systems </li></ul></ul><ul><li>Availability </li></ul><ul><ul><li>Publishers </li></ul></ul><ul><ul><li>Other Universities </li></ul></ul><ul><ul><ul><li>Courses, knowledge bases, project environments, portfolios, Learning Management Systems (LMS) </li></ul></ul></ul><ul><ul><ul><li>Departments </li></ul></ul></ul><ul><ul><ul><li>Faculties </li></ul></ul></ul><ul><ul><ul><li>University </li></ul></ul></ul><ul><ul><ul><li>World </li></ul></ul></ul>
    11. 11. Larger Scale of Reuse (2) <ul><li>Creating material not using HTML </li></ul><ul><li>Using templates that could be used by everyone </li></ul><ul><li>Making material available for exchange trough metadata </li></ul><ul><li>Using standards </li></ul><ul><li>Learning Content Management System (LCMS) </li></ul>
    12. 12. Metadata <ul><li>Describes the content/data </li></ul><ul><ul><li>How is it related </li></ul></ul><ul><ul><li>Where is it used for </li></ul></ul><ul><ul><li>Who created it </li></ul></ul><ul><ul><li>Who may read it </li></ul></ul><ul><ul><li>How large is it </li></ul></ul><ul><ul><li>When is it created </li></ul></ul><ul><ul><li>What is the purpose of the content </li></ul></ul><ul><ul><li>What is the subject </li></ul></ul><ul><ul><li>…… .IMS, IEEE, IACC, SCORM standards </li></ul></ul>
    13. 13. Creating Metadata for Content content metadata content
    14. 14. Content Metadata Creation
    15. 15. Content Metadata List
    16. 16. Content Metadata Document
    17. 17. Learning Content Management System (LCMS) content metadata content content
    18. 18. Selecting Resources
    19. 19. XML Exchange metadata
    20. 20. SCORM and XML SCORM Title MetadataScheme CourseName Cateloque UniqueIdentifier Language Description KeyWord Keyword Keyword Keyword
    21. 21. Questions <ul><li>What keywords to use? </li></ul><ul><li>Who decides about what? </li></ul><ul><li>How to find & select the right content? </li></ul><ul><li>Standards? </li></ul>
    22. 22. Discussion <ul><li>More problems identified? </li></ul><ul><li>Do we really want to reuse? </li></ul><ul><li>What standards do we need? </li></ul>
