Book excerpt: Educating for Sustainability presents fundamental principles, theoretical foundations, and practical suggestions for integrating education for sustainability into existing schoolwide systems and programs, organized in three sections: Principles of Education for Sustainability; Fostering a Sustainability Worldview; Learning and Thinking for Sustainability. Designed for teachers and teachers-to-be at all grade levels and across the content areas, the focus is on professional practices and pedagogical approaches rather than specific topics often associated with sustainability. Each chapter includes a number of supports to help readers monitor and improve their own professional practice and to deepen their own sustainability wordview, including textboxes in most chapters that provide more detailed or specialized information and a range of application exercises. All chapters include several "Consider This" activities and an "Extend Your Professional Knowledge" feature. Directly grounded in K-12 classroom practice, this book presents useful and realistic information for teachers looking to reorient their work toward sustainability and help their students develop new thinking and problem-solving abilities.
