2. Towards a SOA for Giving Feedback in Informal Learning Environments Christian Glahn christian.glahn@ou.nl Open University of the Netherlands

3. Scope of this presentation

4. Overview Problem Theoretical background Glimpse on the Architecture Embedding SOA

5. The Problem Feedback is difficult to get in open or informal learning environments Feedback on learning processes is hardly facilitated in technological environments Existing approaches are limited to a certain system

6. Background Feedback and self-regulated learning Giving feedback Feedback strategies and feedback presentation

7. Feedback and Self-regulated Learning

8. Giving Feedback

9. Feedback Strategies and Feedback Presentation Group Awareness Strategy Cues User Activity Positioning and Navigation 360° Feedback Strategy Strategy Strategy Strategy

10. Feedback Strategies and Feedback Presentation Group Awareness Positioning and Navigation 360° Feedback Cues User Activity Strategy Strategy Strategy Strategy Strategy Strategy Select the right information and the right representation at the right time

11. Towards an Architecture

14. O.K. That’s nice but …

15. Extending the Core Architecture

16. User Monitoring

17. Feedback Injection Brute force changes of the user interface Hiding the application behind a proxy Making use of server-side content filtering e.g. utilise Apache’s mod_filter

18. Next Steps Identify useful information for self-regulated learning Find and develop visualisations that affect learning Identify “good” feedback strategies Identify easy-to-use method of describing feedback strategies
