10. 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
Challenges
Navigational disorientation
„lost in hyperspace“
Conceptual disorientation
Lack of integrating information in the own knowledge structure
Cognitive Overload
Finding information, analyzing found hits, organizing found information, …
Challenges for
Platforms and
Pedagogy
