Describes a first approach to implement e-portfolios in ActiveMath
Text of 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

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?

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

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
