User Model Serivces for Adaptive Work-integrated Learning

Master's thesis Günter Beham 2011

A major challenge when designing software for work-integrated learning (WIL) is that the system provides real-time learning support adapted to a user’s situation and background knowledge (adaptive system). In order to adapt to the user’s situa- tion and characteristics, a user model is needed that is continuously updated to the…

Identifikation von relevanten Konzepten in einem Ontologie-basierten Kontext-Modell

Master's thesis Georg Kompacher 2011

E-Learning has been predominantly seen as a course management system focusing mainly on the needs of the instructor. We view E-Learning as being the Knowledge Transfer aspect of Knowledge Management, with networked systems facilitating knowledge creation, organization and archiving. We propose a Knowledge Management Model for Guided Internalisation that enables…

Technology-Enhanced Workplace Learning: Modelling Competence and Performance for the Case of Requirements Engineering

Thesis (old curriculum) Barbara Kump 2006

From a psychological point of view, two models are required for the construction of an adaptive learning environment for informal, self-directed work-integrated learning (e.g., APOSDLE): the Knowledge Base, a model of the structured expert knowledge of a domain, and the S tudent Model, a model of the competencies of the…
