A number of the attendees from FlipCamp Music Theory 2013 joined together to form the editorial board for a new project, a crowdsourced ebook on student-centered pedagogy in university-level music courses. The result of that project is Engaging Students: Essays in Music Pedagogy.
There are two volumes published to date:
Volume 1 (2013)
Volume 2 (2014)
Volume 3 (2015)
Engaging Students: Essays in Music Pedagogy, Volume 3, is now published!
