Towards a SOA for Giving Feedback in Informal Learning Environments

Christian [email protected] 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

Background

• Feedback and self-regulated learning

• Giving feedback

• Feedback strategies and feedback presentation

O.K. That’s nice

Extending the Core Architecture

User Monitoring

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
