Visualizing Wiki-Supported Knowledge Building: Co-Evolution of Individual and Collective Knowledge Andreas Harrer, Catholic University Eichstätt-Ingolstadt Johannes Moskaliuk, University of Tuebingen Joachim Kimmerle, University of Tuebingen Ulrike Cress, Knowledge Media Research Center WikiSym‘08, September 10th, Porto

Wikis are valuable tools for successful collaborative knowledge building.

knowledge building as a socio-cultural process that takes place in a community

a knowledge building community may use (social) software to contribute their ideas

What exactly happens during knowledge building? How can we describe knowledge-building in more detail?

Interplay between social systems and a cognitive system wiki‘s information social system people‘s knowledge cognitive system

Mutual evolution of a social and a cognitive system internalization externalization

Four processes of learning and knowledge building qualitative individual learning (acquisition of conceptual knowledge) qualitative knowledge building accommodation quantitative individual learning (acquisition of factual knowledge) quantitative knowledge building assimilation internalization externalization

Wikis are first-class examples of sucessful knowledge building supported by (social) software users have many opportunities to influence the content wikis are perfect for inducing socio-cognitive conflicts framework for solving conflicts

socio-cognitive conflicts and their solution as the key “incitement” factor socio-cognitive conlict energy is wave-like energy is particle-like Wave–particle duality

How to investigate knowledge building?
