TeLLNet MotivationA community of learners collaborating in projects (eTwinning)

What is changed? number of members number of collaborations new tools (website, blog, comments on projects, etc.) more projects with heterogeneous partners

- What are properties of communities of learners?- Can a community of learners self-reflect or does it need a support? - How does a community of learners express purposes and goals?- What happens if goals of a community of learners are fulfilled?

2005 2008

A bigger number of projects, considerably collaborating members

TeLLNet The Challenge of Pattern Sharing

Pattern name: A troll a description Pattern disturbance: In a mailing list, any person who posts only in

threads started by herself is considered as a troll a condition Pattern description: A troll aims at drawing attention and starting

useless discussions explains the problem Pattern forces: Troll, Thread, Message actors that force a disturbancePattern forces relations: A troll posts in threads that were started by

himself corresponds to relations between forcesPattern solution: … actions that need to be carried out in the situationPattern rationale: … reasoning about forces and disturbancesPattern relations: … make the structure of pattern language clear

[KSD06, Alex78]

What do we need to share successful patterns?- PALADIN [KSD06]

TeLLNet Future Work Self-modeling phase:

– Researching how the Self-modeling phase contributes to the Self-reflection phase and vice versa

– Assessment and utilizing of learners‘ competences and community patterns in i* models of communities

Self-reflection phase: – Semantization of pattern language PALADIN– Discover fitness patterns of E-Learning communities over the

course of time, storage and sharing of the patterns Evaluation

– Simulation of e-learning communities– Test patterns with real communities and get estimations
