    1. 1. ePortfolio in Martin Homik, Erica Melis -- ActiveMath Group –- www.activemath.org ePortfolio 2005, Cambridge German Research Center for Artificial Intelligence (DFKI GmbH) Saarland University
    2. 2. Outline <ul><li>Motivation </li></ul><ul><li>ActiveMath </li></ul><ul><li>Workbook (ActiveMath’s ePortfolio) </li></ul><ul><li>Capturing Semantics in Workbook </li></ul><ul><li>Architecture </li></ul><ul><li>Conclusion </li></ul>
    3. 3. Motivation <ul><li>Current ePortfolios: standalone applications </li></ul><ul><ul><li>Integration into large systems, in general? </li></ul></ul><ul><ul><li>Integration into learning environments? </li></ul></ul><ul><li>Definition: “… collection of evidences…” </li></ul><ul><ul><li>How to capture reflection on processes? </li></ul></ul><ul><ul><li>How to turn implicit knowledge into explicit one? </li></ul></ul><ul><li>Function: store and provide access </li></ul><ul><ul><li>How to support users? </li></ul></ul>
    4. 4. ActiveMath <ul><li>Web-based </li></ul><ul><li>User-adaptive </li></ul><ul><li>Interactive </li></ul><ul><li>Semantic KR </li></ul><ul><li>Service-based </li></ul>
    5. 5. ActiveMath <ul><li>Web-based </li></ul><ul><li>User-adaptive </li></ul><ul><li>Interactive </li></ul><ul><li>Semantic KR </li></ul><ul><li>Service-based </li></ul>
    6. 6. ePortfolio in ActiveMath (Workbook)
    7. 7. Assembly Tool <ul><li>Students are “book smart” </li></ul><ul><li>Assemble own books </li></ul><ul><li>Supports meta-cognitive skills </li></ul><ul><li>Store locally/upload </li></ul>
    8. 8. Learning log <ul><li>Self-managed documentation of learning objectives </li></ul><ul><li>Base on experience with paper logs </li></ul><ul><li>Reflection on: </li></ul><ul><ul><li>Content </li></ul></ul><ul><ul><li>Process </li></ul></ul><ul><ul><li>Meta-Cognition </li></ul></ul>
    9. 9. Hypotheses <ul><li>Formulation and justification </li></ul><ul><li>Annotated by beliefs </li></ul><ul><li>Supports: </li></ul><ul><ul><li>Reasoning </li></ul></ul><ul><ul><li>Problem solving </li></ul></ul><ul><ul><li>Argumentation </li></ul></ul>
    10. 10. Views and Queries <ul><li>List entries: all/specific type/specific period </li></ul><ul><li>… related to a specified learning object </li></ul><ul><li>… related to LOs a learner does not understand </li></ul><ul><li>… related to LOs a learner did not understand in first place, but has learned meanwhile. </li></ul><ul><li>… . </li></ul>
    11. 11. Capturing Semantics <ul><li>By structure </li></ul><ul><ul><li>We know what we ask </li></ul></ul><ul><li>By multiple choice questions </li></ul><ul><ul><li>We can interpret answers </li></ul></ul><ul><li>By template answers </li></ul><ul><ul><li>We can interpret answers without full understanding </li></ul></ul><ul><li>By drag&drop </li></ul><ul><ul><li>We can relate entries to learning objects </li></ul></ul>
    12. 12. Capturing Semantics: Structure <ul><li>Questions related to: </li></ul><ul><li>General data </li></ul><ul><li>Content </li></ul><ul><li>Process </li></ul><ul><li>Meta-cognition </li></ul><ul><li>Label </li></ul><ul><li>Privacy </li></ul><ul><li>Date </li></ul><ul><li>What was the lesson about? Write a summary. </li></ul><ul><li>What did you (not) understand? </li></ul><ul><li>Formulate questions to issues you did not understand. </li></ul><ul><li>What kind of tools or resources did you use for solving? </li></ul><ul><li>Who helped you? </li></ul><ul><li>What difficulties arose during problem solving? </li></ul><ul><li>What learning objects were most helpful to you? </li></ul><ul><li>How would you rate your performance? </li></ul><ul><li>Did you achieve your goals? If not, why? </li></ul><ul><li>Who can help you? </li></ul>
    13. 13. Capturing Semantics: Drag&drop http://demo.activemath.org:8080/... mbase://LeAM_calculus/diffquot/def_diff_quot
    14. 14. Architecture Math Knowledge Base Learner Model Server Clients Web Server Manager retrieve JNLP (http) Learning log Database
    15. 15. Outlook <ul><li>Evaluation: </li></ul><ul><ul><li>Currently in seminar with 15 university students </li></ul></ul><ul><ul><li>Planned for LeActiveMath EU-Project </li></ul></ul><ul><li>Investigate learning logs (types, semantics, …) </li></ul><ul><li>Enhance collaboration </li></ul><ul><li>Increase interaction with ActiveMath’s services </li></ul><ul><li>Compare learning logs with learner model </li></ul><ul><li>Integration of more reflection-supporting tools </li></ul><ul><li>(Examine) Export in IMS ePortfolio </li></ul>
    16. 16. Conclusion <ul><li>ePortfolios in learning environments </li></ul><ul><ul><li>Not restricted to collection of evidences </li></ul></ul><ul><ul><li>Store reflection processes </li></ul></ul><ul><li>Explicit reflection supports meta-cognition </li></ul><ul><li>Capturing semantics enables provision of user-adapted support </li></ul><ul><li>Still a lot of interesting work to do. </li></ul>
