"Introduction to Guitar" with Thaddeus Hogarth is a beginner's course that will teach you "the fundamentals that you need to get you playing and keep you playing,"  using either an acoustic or electric guitar. You can preview the lessons or download the free guitar playing handbook here. More advanced students will benefit from "Introduction to Improvisation" with six-time Grammy Award winner Gary Burton. Both courses start on April 22nd.
open2study or "Aussie Coursera" is a new MOOC's platform from Open Universities Australia . Starting classes include "Introduction to Nursing in Healthcare" , "Writing for the Web", "Principles of Project Management", and other career-oriented, 4-week MOOCs from a range of institutions. The thoughtful course design -"a mixture of six to ten minute videos, animations, simulations and quizzes, designed using high production values" , open forums, and a “Where could this take me?“ section that links each course to its related career could be a winning recipe in online education.
NovoEd (re-branded Venture Lab) from Stanford's professors is based on "collaboration,
project, and team-based learning."  Seven courses will be offered this spring
