ePortfolios in ActiveMath

• 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. Outline

• Motivation

• ActiveMath

• Workbook (ActiveMaths ePortfolio)

• Capturing Semantics in Workbook

• Architecture

• Conclusion

3. Motivation

• Current ePortfolios: standalone applications

• • Integration into large systems, in general?

• • Integration into learning environments?

• Definition: collection of evidences

• • How to capture reflection on processes?

• • How to turn implicit knowledge into explicit one?

• Function: store and provide access

• • How to support users?

4. ActiveMath

• Web-based

• User-adaptive

• Interactive

• Semantic KR

• Service-based

5. ActiveMath

• Web-based

• User-adaptive

• Interactive

• Semantic KR

• Service-based

6. ePortfolio in ActiveMath (Workbook) 7. Assembly Tool

• Students are book smart

• Assemble own books

• Supports meta-cognitive skills

• Store locally/upload

8. Learning log

• Self-managed documentation of learning objectives

• Base on experience with paper logs

• Reflection on:

• • Content

• • Process

• • Meta-Cognition

9. Hypotheses

• Formulation and justification

• Annotated by beliefs

• Supports:

• • Reasoning

• • Problem solving

• • Argumentation

10. Views and Queries

• List entries: all/specific type/specific period

• related to a specified learning object

• related to LOs a learner does not understand

• related to LOs a learner did not understand in first place, but has learned meanwhile.

• .

11. Capturing Semantics

• By structure

• • We know what we ask

• By multiple choice questions

• • We can interpret answers

• By template answers

• • We can interpret answers without full understanding

• By drag&drop

• • We can relate entries to learning objects

12. Capturing Semantics: Structure

• Questions related to:

• General data

• Content

• Process

• Meta-cognition

• Label

• Privacy

• Date

• What was the lesson about? Write a summary.

• What did you (not) understand?

• Formulate questions to issues you did not understand.

• What kind of tools or resources did you use for solving?

• Who helped you?

• What difficulties arose during problem solving?

• What learning objects were most helpful to you?

• How would you rate your performance?

• Did you achieve your goals? If not, why?

• Who can help you?

• Evaluation:

• • Currently in seminar with 15 university students

• • Planned for LeActiveMath EU-Project

• Investigate learning logs (types, semantics, )

• Enhance collaboration

• Increase interaction with ActiveMaths services

• Compare learning logs with learner model

• Integration of more reflection-supporting tools

• (Examine) Export in IMS ePortfolio

16. Conclusion

• ePortfolios in learning environments

• • Not restricted to collection of evidences

• • Store reflection processes

• Explicit reflection supports meta-cognition

• Capturing semantics enables provision of user-adapted support

• Still a lot of interesting work to do.
