Robust and effective classroom discussions are essential for providing students with opportunities to simultaneously engage in science practises while learning key science content. Using numerous examples and science learning tasks, the authors show how teachers can plan the lesson to encourage students to not only learn science content but employ disciplinary practises as well.

Now in its second edition, this essential textbook and professional development resource offers a new foreword by James Hiebert and two important new chapters that focus on the ways in which the book can be used to support the learning of teachers and administrators, drawing on the authors' work over the past decade. Chapter 11 illustrates the various ways in which teacher educators or professional developers might use the materials in the book to aid in the professional growth of teachers, including how to directly improve teachers' instruction practices. Chapter 12 discusses ways in which principals and school leaders can use the book to become better instructional leaders of teachers who are attempting to teach with cognitively demanding tasks.

Helping students develop an understanding of important mathematical ideas is a persistent challenge for teachers. In this book, one of a three-volume set, well-known mathematics educators Margaret Smith, Edward A. Silver, and Mary Kay Stein provide teachers of mathematics the support they need to improve their instruction. They focus on ways to engage upper elementary, middle school, and high school students in thinking, reasoning, and problem solving to build their mathematics understanding and proficiency. The content focus of Volume Two is algebra.
