Maybe you’ve seen DVD or audio university courses available in bookstores, but you knew there were coming online–for free. The iTunes Store has a great assortment of FREE classes and even courses available from dozens of universities (called iTunes U) including Cambridge, Cornell, Dallas Theological Seminary, Oxford, Yale and many others. Some classes are on video, most are audio.
In Michigan, while working one cleaning job, I listened my way through most of J.I. Packer teaching the History and Theology of the Puritans available from the iTunes U store of Reformed Theological Seminary.
There is not credit available going this way, but it is an excellent enrichment tool to help you hone and develop the talents God gifted you.
Today I also found this site Academic Earth which seems to offer all video lectures, but is much more limited so far in its offerings. If you dig a few minutes, you will likely find something of great interest and personal enjoyment.
I especially commend iTunes U. And iTunes is a free download.
