This comprehensive volume advances a vision of teacher preparation programs focused on core practices supporting ambitious science instruction. The book advocates for collaborative learning and building a community of teacher educators that can collectively share and refine strategies, tools, and practices. A renewed interest in practice-based teacher education paired with increasingly rigorous requirements, notably the Next Generation Science Standards, has highlighted the importance of teachers' deep disciplinary knowledge. This volume examines the compelling ways teacher educators across the country are using core practices to prepare preservice teachers for ambitious and equitable science teaching. With contributions from a wide network of teacher educators focusing on science education in various geographical and institutional contexts, "Preparing Science Teachers Through Practice-Based Teacher Education" serves as a valuable resource both for teacher educators and for administrators.
