The importance of meaning and relevance makes it possible for stakeholders to drill deeper than organizational structures; it is a critical component of teaching and learning through curriculum and assessment. A.Z. shares an approach to personalized learning that provides teachers the framework to create instruction that is meaningful and relevant for their students and that builds on the brain research discussed in the introductory chapter. It provides students the opportunity to make meaning, to build from prior connections, and to understand the relevance of their schoolwork to broader world connections. D.L. describes the innovative Big Picture Schools model he established around the idea of providing students with the opportunity to explore their interests and cultivate their passions through real-life learning experiences. He also shows that this model served as a highly effective platform for deep learning. It is the process of learning that is emphasized and transferred to future learning and real work experiences. Finally, E.O.-O., a bilingual science teacher, uses caring and an understanding of the developmental challenges faced by her students to develop meaningful learning activities for her students. Her approach makes it possible for her “emergent bilinguals” to make connections to the curriculum and to use their culture as a resource in the classroom.
