iTunes U, Apple's educational catalog on iTunes, has gotten a whole lot more useful with a significant update to the official iPhone and iPad app in the App Store.
As first reported Thursday by Re/code, iTunes U for iOS has gained an interesting homework hand-in feature and PDF annotations providing a timestamp when the student submits term papers, book reports and other work.
Other changes include an integrated grade book, one-to-one discussions, importing content from third-party apps, including Apple’s own Keynote, Pages and iMovie, and more.
