The Choice Between Discipline-based Art Curriculum Or A Choice-based One

I would put a disciplined-based curriculum first, but I am open to a choice-based one.  I think that they both have variables that can benefit a classroom.  Within a choice-based classroom you would allow students more freedom.  I think it is important for students to have guidelines and follow directions during earlier years of youth and as they grow older allowing students more freedom.  D.B.A.E. provides a base in my lesson plans, but there is also room for other attributes within a curriculum.  It is important that I can evaluate that the students are learning from the lesson plans I am teaching, therefore a disciplined-based curriculum provides me with this.
