This book provides instructors and students in entry-level interdisciplinary courses and thematic programs with a comprehensive introduction to interdisciplinary studies. Authors Allen F. Repko, Rick Szostak, and Michelle Phillips Buchberger introduce students to the cognitive process that interdisciplinarians use to approach complex problems and eventually arrive at more comprehensive understandings of them. Students learn how to think like interdisciplinarians, understand interdisciplinary processes, and assess the quality of their own work. Changes to the Fourth Edition include revised content on epistemology and methods, more on integrative strategies, reordering of some chapters, new assignment ideas, and new examples which include student examples and insights from the latest scholarly works.
