As Apple previously announced, the company has updated its iTunes U app today. iTunes U 2.0 allows teachers to create courses within the free app on iPad. The iPad’s camera can be used to take photos or videos to be uploaded for course materials. It’s also possible for teachers to create materials in Pages, Numbers, Keynote or other apps and add them to a course by using the “Open in iTunes U” option, and teachers from qualified institutions can make their courses available on the iTunes U catalog. Additionally, the update makes it easier for students in private courses to pose questions and participate in discussion.
