Book excerpt: Action Research for Classrooms, Schools, and Communities is a core textbook for the action research course. This book addresses the trend toward high-stakes testing and teacher accountability by focusing on understanding student outcomes. With edTPA rapidly becoming part of the requirements for teacher certification, teacher preparation programs will increasingly be looking to measure the impact of the teacher candidate on student learning. The book focuses on the potential for action research to lead to greater understanding about student outcomes from the perspective of teachers, school leaders, and community members. There is a special emphasis on helping pre-service and experienced teachers use action research to understand their impact on student learning. There is an emphasis on using action research to understand community impacts on schools; unlike other books, this text acknowledges the complex ecology linking classrooms, schools, and the community, especially regarding issues fundamental to school reform.
