In this third volume of It’s All About Thinking, the authors focus on teaching and learning in the middle years, transforming principles into practices, and exploring such questions as: How can we help students develop the competencies they need to become successful learners? How can we create pathways to deep learning of important concepts? How can we engage and support diverse learners in inclusive classrooms? Nicole, Linda, and Leyton explore these questions and offer classroom examples to help busy teachers develop communities where all students learn, focusing on the big ideas in middle years education today.
