Massive open online coursesor MOOCsare all the rage in higher education. But law schools are only starting to test the waters with these free, Internet-based classes that can reach thousands of students around the globe.

Three law schools and universities will offer law-related MOOCs this fall for the first time, and Harvard Law School plans to again offer an online copyright course it debuted last year. Northwestern University, The John Marshall Law School and the University of North Carolina at Chapel Hill are among those joining the MOOC movement, although participants won’t earn credits for the classes just yet.
