Challenges of Resource Based Learning

In resource based learning the learning process Is self organized (in different graduations)Does not follow fixed didactic or organizational settings

ChallengesNavigational disorientation

„lost in hyperspace“Conceptual disorientation

Lack of integrating information in the own knowledge structureCognitive Overload

Finding information, analyzing found hits, organizing found information, …Challenges for
