Learn stuff for free through iTunes U.

iTunes UIn 2007, Apple jumped on the free online college course bandwagon through its iTunes application. Here you will find iTunes U, a selection of recorded videos, ebook, .pdf files and podcasts from courses offered by a variety of schools including Harvard, Stanford, and Earlham Community School District. These days, iTunes U offers “courses”, as noted by the binding on the left side of the course icon, and “collections”, that is, gatherings of lectures on a topic. For example, “Statistics 101”, taught by Harvard’s Joseph Blitzstein, was designed as a class, whereas “What Great Bosses Know” is a collection of podcasts from Poyntner Intsitute’s Jill Geisler. All are available on a desktop computer through iTunes or through the iTunes U app for iPad or iPhone. These courses are offered freely, but one cannot get college credit for them.
