This one-of-a-kind casebook features 24 contributed cases which present richly detailed, authentic instructional design situations. It is an ideal supplement for any introductory instructional design course textbook and can also be used as a main text in advanced courses for students who already possess the foundational knowledge of the subject. The cases help students bridge the gap between the complexities of the design world and the isolated principles taught in traditional instructional design courses. By encountering a variety of issues, contexts, and content areas, students have the opportunity to apply the principles of instructional design to realistic problems they will encounter when they become practitioners.
