If you are not using the principles of design in your dance classroom, I would encourage you to think about using these as a starting point for teaching best practices in choreography.  Friends, I have to tell you that after 14 years of teaching I am just discovering the importance of talking about these design principles every week.  I began my school year introducing these design principles to my students.  This week I am teaching folk dance and introduced the Hukilau from Hawaii.  As I shared a video of this dance with my students, one of my students said that he recognized the principle of design called repetition in the dance.  What is amazing is that he noticed that without my even asking!  I am so excited about this transforming year in my teaching career!  I hope that I can inspire at least one other teacher to think about ways to use these concepts each and every day!  It is so important to never stop learning as a teacher and to grow your teaching style each year!
