Education and cognitive psychology are natural companions-they both are focused on how people think and learn. Although collaborations have occurred for many years, recently there has been a much greater interest in collaborations that bring cognitive principles into classroom settings. This renewed collaborative research has led both to new evidence-based instructional practices and to a better understanding of cognitive principles. This volume contains overviews of research projects at the intersection of cognitive science and education. The prominent contributors-cognitive psychologists, developmental psychologists, educational psychologists, and science educators-were chosen both for the quality of their work and the variety of their contributions-general principles; influence of affect and motivation; and focus on math and science education.
