In spite of all the interest in both agile methods and MOOCs (Massive Open Online Courses) there are few courses on agile methods; I know only of some specialized MOOCs focused on a particular language or method.
I produced for EdX, with the help of Marco Piccioni, a new MOOC entitled Agile Software Development. It starts airing today and is supported by exercises and quizzes. The course uses some of the material from my Agile book.
Registration is free and open to anyone at this address.
