"This collection of stories by teachers demonstrates that children collect and structure data, build their own arguments by appealing to evidence and reason to support claims, and revise models as needed. In all, a very impressive documentation that we have underestimated the capability of students to learn mathematics and science with understanding."
—Thomas A. Romberg, Bascom Professor of Education, University of Wisconsin-Madison

This book looks at how teachers implement national math and science standards in their classrooms. A collaboration between Richard Lehrer and Leona Schauble (education researchers) and elementary school teachers, these teacher-authored chapters provide important insights about how children think and reason as they pose questions, collect data, and build data models to answer their questions. While the spotlight is primarily on student understanding and its development over time, the text also highlights teachers' professional development of a specific form of knowledge. Becoming a virtual observer" as teachers orchestrate data modeling activities in their classrooms, you'll see not just what was taught, but how it was taught.
