K3

K3 (German acronym for communication, collaboration, competence) is a knowledge management system in learning environments for higher level academic teaching.

K3 is based on the assumption that knowledge production is to a large extent the result of communication processes.

Information Engineering - Department of Computer and Information Science at the University of Constance

Basic assumption of the K3 project

Assumption: Learning can be especially effective and motivating, if different people share their knowledge and are committed to argumentation and negotiation to work out common results and producing new knowledge (collaborative knowledge construction).

Information Engineering - Department of Computer and Information Science at the University of Constance

Objectives

K3 as a tool for collaborative work in virtual groups

to let virtual groups (and in them, of course, individual learners) produce content and acquire knowledge in the

special course domain

to acquire information and communication competence

Functions of constructivism Cognitive: Learning produces sustainable results when external

information or the requirements of a task can be embedded in already existing cognitive structure, be it as confirmation, modification or contradiction of the learner’s existing knowledge

Motivation: The learning process will be better accepted and will lead to permanent (sustainable) knowledge when learning can be experienced as the result of one’s own activity, not as a mere adaptation to the knowledge of other people

Social construction: Understanding, knowledge acquisition and production is to a great extent socially constructed, based on collaborative knowledge-sharing interaction with others.

Evaluation and feedback by the students

Main result: Students judged their learning success as high to very high.

DidacticsVariation and combination of teaching methods raises motivation

and improves learning success

Especially group work is judged as raising motivation and facilitating learning success

Blended learning is clearly considered the most attractive learning environment ---- but:

Classic lecturing is seen as an important part of the course

Virtual (group) learning cannot/should not replace F2F communication

Information Engineering - Department of Computer and Information Science at the University of Constance

Evaluation and feedback

Progressional rating improves motivation and raising learning success

Instructionalistic components (work assignments, work tasks) are extremely important both for orientation and group work success

Asymmetric levels of competence are considered positive for group work learning

Mixture of evaluation procedures (group work, roles, summaries, presentations, individual work) clearly raises motivation and level of participation
