itunes u user group wanted

Dear all,

this post is not looking for technical advise, but for an exchange in experiences made sofar in applying the fascinating eTools to real students: is there a kind of experiences made, 'dos and donts' in introducing the technological possibilities of iTunes U?

Some of my basic questions: my students are bored looking into the iTunes U assessments section, not motivated clicking additional material explaining the matter of the lecture, too lazy posting questions, do not explore the learning-cards and glossary section in my eBook of the lecture and so on.

Kind regards,

Luc
