Merging the Instructional Design Process with Learner-Centered Theory [PDF ebook] 
The Holistic 4D Model

Merging the Instructional Design Process with Learner-Centered Theory brings together the innovations of two previously divided processes — learning design strategies/theories and instructional systems development — into a new introductory textbook. Using a holistic rather than fragmented approach that includes top-level, mid-level, and lower-level design, this book provides guidance for major topics such as non-instructional interventions, just-in-time analysis, rapid-prototype approaches, and learner-centered, project-based, anytime-anywhere instruction. Informed by the authors’ considerable experience and leadership throughout dramatic shifts in today’s learning landscape, this book offers the next generation of instructional designers a fresh perspective that synthesizes and pushes beyond the basics of design and development.
