Contextualizing electronic learning systems

Electronic learning systems (ELS) should be contents independent to simplify or enable their reuse with various contents components. Contents independence, however, implies that ELS shouldn´t aim at limiting learning space complexity or size. Rather, ELS should aid learners in navigating this space. ELS adaptation to learning style, learner´s characteristics and preferences might impact learners accepting these systems. Learners can use the plain look-up function or functions derived from it to trace back to a learning unit.
