Wait, technology is really used in dance education!?
Apparently this is truth! Who knew?:) I found the greatest book that proves this fact. The book is called International Handbook of Research in Arts Education (Springer International Handbooks of Education, 2007, Volume 16, Section 12, 1381-1397, DOI:10.1007/978-1-4020-3052-9_94) and there is a section in it called "Technology in Dance Education" written by Mila Parrish.
Here is a link to the abstract of this section and places where the book can be found!
