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

11. 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).

12. 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  Objectives

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

38. Information Engineering - Department of Computer and Information Science at the University of Constance Evaluation and feedback by the students Main result: Students judged their learning success as high to very high. Didactics  Variation 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

39. 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
