SO FRESH AND SO CLEAN: Lots of announcements for you iPad fans this past week. In addition to the iTunes U updates (Apple announced that starting July 8, iTunes U will allow teachers to create, manage, and share iTunes U courses on iPads, among other things), iOS 8 is getting some educator attention. Apple is providing a peek into its new iOS 8 offerings for education on its site. Offerings will apparently include “better document workflows,” Apple TV updates and new ways to manage books and PDFs.
