Coaching, as a means to support inquiry-based teaching, starts by changing the culture from within (school, teacher, and student) rather than from external mandates.

Through sustained collegial interactions within a strong support system provided by coaches, teachers are more willing to leave their comfort zone on a path of continuous improvement toward inquiry-based teaching and learning. This article describes how one school district in Massachusetts implemented this approach with success.
