As district leaders consider professional learning opportunities for educators, mobilizing new thought and actions across an entire system is a vexing challenge. Classroom-based learning may unfortunately be viewed as juxtaposed to district-based learning. It becomes essential for district leaders to develop knowledge mobilization strategies which provide a framework for any district-wide focus or initiative. In doing so, opportunities for "knowledge influencers" to interact with each other at various levels of the educational system are intentionally enhanced, that is, at the classroom, school, and district levels. Knowledge creating groups are thereby encouraged to challenge the status quo and promote innovation.
