Towards a SOA for Giving Feedback in Informal Learning Environments
Christian [email protected] University of the Netherlands
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
Background
• Feedback and self-regulated learning
• Giving feedback
• Feedback strategies and feedback presentation

Feedback Injection
• Brute force changes of the user interface<div id=“fbwidget”/>
<script type=“text/javascript” src=“feedbackhelper.js”/>
• Hiding the application behind a proxy
• Making use of server-side content filteringe.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
