Book excerpt: Learning design is an ill-structured process that must account for multiple stakeholders, contextual constraints, and other instructional needs. Whereas many theories outline learning theories, less is known about the formative design process and how it impacts the design and development of learning technologies. This is critical because a formative view considers the issues that educators encounter and how to overcome them during the learning design process. This edited volume provides a multi-faceted look at theories, studies, and design cases that employ formative design in learning across multiple domains. Topics include processes oriented around design thinking, design-based research, and others. Additional chapters provide contextual considerations, such as describing how formative design was used to design learning solutions for STEM learning and food banks, as well as overcoming challenges in emergency remote teaching. In doing so, the book provides an interdisciplinary view that explores how scholars and practitioners engage in formative practices that support a wide array of learners and contexts.
