This is a stub post just to mention The Place of Music in 21st Century Education MOOC to formally fulfill one of the requirements thereof. It shall not be construed as an endorsement or recommendation from my part to enroll.
(To my peers: I am a kind of mutiprofessional, so there are posts and pages dedicated to many different subjects. Worse, I am a kind of multilingual, so they may involve strange tongues impenetrable to most of you (you might wish to restrict scope to English posts only).
My page on Selected music resources for adult students of music may be of particular interest—and, I hope, of some help—for my peers. It is in English as well as most of the resources mentioned and annotated in it.)
