Drawing on their research in nine of New York City's most poverty‐impacted schools, the authors dive deep into school systems and routines, as well as into teachers' practices and students' experiences. They also zoom out to capture the larger currents that have made this school reform strategy so prominent today. Each chapter includes a discussion of a new direction that schools and teachers can take to ensure that data use in teaching actually spurs growth in learning. This resource extracts lessons from both chaotic and productive data implementation in order to inform practice and fulfill hopes for better schooling, richer teaching, and deeper learning.
