Action Research Communities presents a new perspective on two current and proven educational practices: classroom-/school-based action research and professional learning communities. Within the text there is an excellent blend of theory and practice to be found, along with much author insight (borne out of Dr Mertler's own classroom and research-based experience) which make for an instructional and engaging read. The text itself can be enjoyed by a wide audience, including those who are well-versed in action research methodology, as well as the novice or beginner. It is my sincere and fervent hope that this text will inspire many teachers, school leaders and district administrators to adopt and sustain the ARC model as espoused by Dr Mertler.
