making the transition to choice

I have decided to convert the art classroom into a choice studio. What on earth is a choice studio you ask? Well, in a nutshell it is a way of "teaching" that enables students to choose between a variety of centers in the art room to communicate their own creative visions. Essentially the choice studio enables children to think and work like artists. They have full access to many different art materials at once. Just like in a real artist studio. If you are interested in a more in depth discussion I have included a few links for your reading enjoyment. I will be posting updates as I make this very exciting transition.
