This book offers insights into how design-based processes, principles, and mindsets can be productively employed in diverse P-16 educational spaces by a myriad of educational actors including teachers, instructional leaders, and students. It addresses concerns about the theoretical and practical implications of the still emergent emphasis of design in education.  The book begins by examining a number of prominent design processes being used by educators including human-centred design, designing for authentic inquiries, and Universal Design for Learning. It then delves into how teachers, system leaders, and students can engage in educational design within the complex spaces of K-12 contexts. Finally, the book takes up design in education within a maker and making context. Each chapter includes a vignette, a series of guiding questions, along with specific design principles that can help address common challenges and issues educators encounter in their practice.  This book provides both theoretical and practical elements involved in educational design and is beneficial to scholars, graduate students, educators, and pre-service teachers.
