Web-based Adaptive Learning Environments and Open Learner Model – Use in Didactics of Informatics

In the context of this dissertation, issues concerning adaptive Web-based learning environments, the Open Learner Model and its exploitation towards the enhancement of the teaching and learning process are studied. The thesis focuses on the research of Open Learner Models in adaptive Web-based learning environments, aiming to design develop and exploit the open learner model of the Web-based, learning environment SCALE (OLM_SCALE). In the frame of this thesis two empirical studies were conducted: The first one aims to investigate how the educational material in form of activities that exploit the learning design of SCALE, can support the learning process in the context of the undergraduate course “Introduction to Informatics and Telecommunication”. The second one aims to investigate how the facilities offered by OLM_SCALE can be exploited towards the reengagement of disengaged students.
