This resource examines professional development approaches from across the United States to help schools and allied arts groups integrate the arts into an already crowded K-12 curriculum. The authors document the purposes and structures of a broad spectrum of current efforts and programs. Several of these programs have been in place for decades, thus demonstrating their sustainability and effectiveness. Emphasizing the value of collaboration among teachers, artists, educational leaders, and community partners, the book draws on the broad range of experiences of the authors, who came together as a working group of the Art Education Partnership. Readers will find strong, empirically tested models of arts integration to inform curriculum development and teacher professional learning. Book Features: the first critical reflection on arts-integration training programs and projects from across the United States; promising practices for pre- and inservice teacher professional development programs in arts integration; and a summary list of recommendations for actions based on the authors’ collaborative experiences.
