Q: If I post my course materials online, what incentive will my students have for attending class?
A: iTunes U can become a home for entire course lectures and some institutions have chosen to publish some classes in their entirety on iTunes U. However, this does not have to be how you approach the service: you can post smaller course segments, enriching bonus materials, short lecture segments or specific examples. Because many users prefer to watch content that is in shorter in length, posting your entire lectures may be overkill. iTunes U is not intended to completely replace the classroom experience but to augment it, connect it to the global community and make the learning environment more compelling.
Also, because you have control over when content appears on iTunes U, entire lectures could be posted after class is over, allowing students to review lectures for study but not until after an attendance policy requirement has been met for the day.
Q: Can I upload video or audio examples from copyrighted or commercially licensed works to iTunes U?
A: In short, no.
iTunes U is a publicly searchable service and it is absolutely crucial that the content uploaded is allowed to be legally distributed.
