I think anyone can teach a MOOC using Blackboard's public face, CourseSites. It occurred to me that instead of blogging as much in the Spring, I could offer an informal, not for credit course for 8 weeks or so. I'd probably charge $10 for registration.
I doubt enough people would be interested to make it worth the time, but I thought I'd throw it out there. Here are some of the courses I've taught over the years: Greek, Hebrew, Latin, Paul's letters, Hebrews, Jewish literature between the testaments, Jewish afterlife traditions, Bible Study Method, New Testament Survey, philosophy, ???. Languages would require multiple courses to get someone to where they could pass a competency exam somewhere.
The format of a MOOC is usually a series of videos with quizzes, optional discussion, and sometimes a final project. Anyone interested? If you were, what would pique your interest?
