This document summarizes a study on a collaborative action research project using networked technologies to support online professional development for educators. The study involved researchers and practitioners from schools in several countries. It found that the professional development programs deepened teachers' understanding and engagement, and enhanced collaboration. Leaders reported being able to articulate their vision and take strategic action. Students reported greater engagement and understanding. While impacts on systems were gradual, several schools reorganized structures and modified tools and standards to reflect the frameworks. The study demonstrates how online professional learning communities can sustain efforts to improve instruction and student achievement through collaborative action research.
