Tracing knowledge co-evolution in a realistic course setting: A wiki-based field experiment

Computers & Education, Pergamon, 2013

The co-evolution model of collaborative knowledge building by Cress & Kimmerle (2008)assumes that cognitive and social processes interact when users build knowledge with shareddigital artifacts. While these assumptions have been tested in various lab experiments, a testunder natural field conditions in educational settings has not been conducted. Here, wepresent a field experiment where we triggered knowledge co-evolution in an accommodationand an assimilation condition, and measured effects on student knowledge building outsidethe laboratory in the context of two university courses. Therefore, 48 students receiveddifferent kinds of prompts that triggered external accommodation and assimilation whilewriting a wiki text. Knowledge building was measured with a content analysis of the students‟texts and comments (externalization), and with concept maps and association tests(internalization). The findings reveal that (a) different modes of externalization(accommodation and assimilation) could be triggered with prompts, (b) across bothconditions, this externalization co-occurred with internalization (student learning), and (c)there is some evidence that external assimilation and accommodation had differential effectson internal assimilation and accommodation. Thus, the field experiment supports theassumptions of the co-evolution model in a realistic course setting. On a more general note,the study provides an example of how wikis can be used successfully for collaborativeknowledge building within educational contexts.

Scaling Informal Learning: An Integrative Systems View on Scaffolding at the Workplace

European Conference on Technology Enhanced Learning, Springer Berlin Heidelberg, 2013

While several technological advances have been suggested to scale learning at the workplace, none has been successful to scale informal learning. We review three theoretical discourses and suggest an integrated systems model of scaffolding informal workplace learning that has been created to tackle this challenge. We derive research questions that emerge from this model and illustrate these with an in-depth analysis of two workplace learning domains.

Proceedings of {ECTEL} meets {ECSCW} 2013, the Workshop on Collaborative Technologies for Working and Learning, Paphos, Cyprus, September, 21, 2013

CEUR Workshop Proceedings, 2013

Konferenz
With this workshop, we brought together the European communities of technology-enhanced learning, which typically meets at the ECTEL, and of computer-supported cooperative work, which typically meets at the ECSCW. While the ECTEL community has traditionally focused on technology support for learning, be it in formal learning environments like schools, universities, etc. or in informal learning environments like workplaces, the ECSCW community has traditionally investigated how computers can and do mediate and influence collaborative work, in settings as diverse as the typical “gainful employment” situations, project work within university courses, volunteer settings in NGOs etc. Despite overlapping areas of concerns, the two communities are also exploiting different theories and methodological approaches. Within this workshop, we discussed issues that are relevant for both communities, and have the potential to contribute to a more lively communication between both communities.
