3. Overview: -Background -Simulation -Results -Questions

4. Learning Networks ­Facilities for life long learners ­Support seamless, ubiquitous access ­Activity nodes: ­Anything that supports learning ­Course ­Workshop ­Conference ­Web resource ­Providers and learners can create new ANs

5. Background I: Developmental research

6. Learning Networks II ­Self-organized, distributed e-learning systems, designed to facilitate lifelong learning. ­Refers to the connection of ­a large number of actors and learning artifacts into an organization, ­as well as to the physical ICT network and facilities that are responsible for the technical connections.

8. Issues in a learning network: ­Position: Where are you at this moment ­Goal: What do you want to reach ­To do list: Goal – Position ≈ A list of ANs that you still have to complete

9. Problem: How do we support life-long learners to determine their learning path We used the principles of self-organisation to provide Feedback What feedback?

16. Approach – different viewpoints: 1. Analysis of current situation: Case 1 st year of Psychology 2. Simulating the effects of feedback/stigmergy in a Learning network 3. Feedback tool developed and tested in experiment Hypotheses: 1.Increased efficiency in Experimental group 2.Higher path conversions in Experimental group

17. Simulation of a Learning network ­Why a simulation ­To save time ­To test techniques prior to tool development ­To make predictions
