I've posted before here on MOOC’s (Massive Open Online Courses) in higher education, and other open resources. Below are details of a number of upcoming courses. They are free and online, or some provide accreditation if you pay a course fee. You can follow the course and all activities in the timescale set, or you can simply dip in and out of the resources given.
