The first part of this book concerns instructional design practice, or what is it that makes instructional design recognizable as instructional design. Of course, instructional design shares many activities, methods, processes, and techniques with other design, education, or social science fields. So one should focus on instructional design as a particular constellation of practices, the particular configuration of which being what allows instructional designers to make the unique contributions they are prepared to make. 

We divide our study of instructional design practice into four subsections - understanding, exploring, creating, and evaluating - each of which consists of 3 - 5 chapters.
