Wikis are valuable tools for successful collaborative
knowledge building.
![Page 3: Visualizing Wiki-Supported Knowledge Building: Co-Evolution of Individual and Collective Knowledge](https://reader036.fdocuments.us/reader036/viewer/2022062307/556d808ad8b42ab7488b4b1b/html5/thumbnails/3.jpg)
knowledge building as a socio-cultural process
that takes place in a community
![Page 4: Visualizing Wiki-Supported Knowledge Building: Co-Evolution of Individual and Collective Knowledge](https://reader036.fdocuments.us/reader036/viewer/2022062307/556d808ad8b42ab7488b4b1b/html5/thumbnails/4.jpg)
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?
![Page 7: Visualizing Wiki-Supported Knowledge Building: Co-Evolution of Individual and Collective Knowledge](https://reader036.fdocuments.us/reader036/viewer/2022062307/556d808ad8b42ab7488b4b1b/html5/thumbnails/7.jpg)
Interplay between social systems and a cognitive system
wiki‘s informationsocial system
people‘s knowledgecognitive system

Mutual evolution of a social and a cognitive system
internalization
externalization

Four processes of learning and knowledge building
externalization internalization
assimilation quantitative knowledge building
quantitative individual learning (acquisition of factual knowledge)
accommodation qualitative knowledge building
qualitative individual learning (acquisition of conceptual knowledge)
![Page 10: Visualizing Wiki-Supported Knowledge Building: Co-Evolution of Individual and Collective Knowledge](https://reader036.fdocuments.us/reader036/viewer/2022062307/556d808ad8b42ab7488b4b1b/html5/thumbnails/10.jpg)
Wikis are first-class examples of sucessful knowledge buildingsupported by (social) software
users have many
opportunitiesto influence the content
wikis are perfect for inducing
socio-cognitiveconflicts
framework for solving conflicts
