Book excerpt: Institutions of education are in an age of transformational change in which learning has a wider scope of understanding and long-term impact than ever before. Those involved in teaching and learning require additional training and subject matter support towards developing a broader and more profoundly complex understanding of the learners affected by evolving sociological events and associated needs. More than ever, a broader understanding of the learner is needed, inclusive of a learner-centered approach to both teaching and learner cognitive engagement. The Handbook of Research on Learner-Centered Approaches to Teaching in an Age of Transformational Change examines the abundant transformational changes that have occurred and provide strategies to understand and address them. It draws from a wide range of experts and provides a burgeoning understanding of the effects of these rapidly-moving transformational changes that are occurring in the processes of teaching and learning. Exploring a wide range of issues such as community engagement scholarship, motivation-driven assignment design, and trauma-informed practices, this major reference work is an invaluable resource for educators of K-12 and higher education, educational faculty and administration, pre-service teachers, government officials, non-profit organizations, sociologists, libraries, researchers, and academicians.
