This book provides a comprehensive analysis of cutting edge research studies on contemporary instructional design practices. Written for instructional designers, instructional technologists and researchers in the field, it provides state of the art, practically focused information and guidelines for designing curriculum and professional ID practice. The overall purpose of this book is to provide a comprehensive review of 102 studies of instructional design (ID) practices. Studies of ID practices are research on instructional designers’ current practices and activities. For over thirty years, individual researchers have evaluated the practices of ID professionals and instructional designers and ID students (e.g., Kerr, 1983; Zemke, 1985). This summary and analysis of existing research in these studies of ID practices directly impact the Instructional Design and Technology (IDT) discipline. Congratulations, Dr. Sugar!
