A group of online-learning ventures is collaborating on a new kind of free class to be offered this fall, known as a mechanical MOOC (for “massive open online course”), that will teach a computer-programming language by patching together existing resources from open-learning sites.

Unlike courses already available online, the new class will not require a traditional instructor, or a large start-up investment.

The new course, “A Gentle Introduction to Python,” will blend content from M.I.T.’s OpenCourseWare, instant-feedback exercises and quizzes from Codecademy, and study groups organized by OpenStudy, and will be coordinated through an e-mail list operated by Peer 2 Peer University.

“The MOOCs that have come out in the last six months are really incredible and have truly moved the needle for online learning, but they are based on very sophisticated central platforms and require significant resources to develop,” Philipp Schmidt, Peer 2 Peer University’s co-founder, said in a statement.
