Towards a SOA for Giving Feedback in Informal Learning Environments Christian Glahn Open University of the Netherlands

Scope of this presentation

Overview Problem Theoretical background Glimpse on the Architecture Embedding SOA

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

O.K. That’s nice but …

Extending the Core Architecture

User Monitoring

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

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
