Book excerpt: This book addresses the significant problems that can arise for pre-service teachers, teachers and school leaders who are unprepared for the complexities of 21st century teaching. It focuses on major factors impacting teacher preparation during an era of significant change, including student learning, academic growth, classroom practice, and the efficacy of teachers. In turn, the book considers crucial aspects that can enhance educational outcomes and investigates questions including what impact the changing nature of teachers’ work has on teacher preparation; how educators can evaluate blended learning; and what impact teachers have on learners. This book provides evidence-based approaches that can be used to achieve a positive impact on education and narrow the gap in contemporary and emerging global topics in education.
