The Third Edition of Interdisciplinary Research: Process and Theory offers a comprehensive and systematic presentation of the interdisciplinary research process and the theory that informs it. Authors Allen F. Repko and Rick Szostak illustrate each step of the decision-making process by drawing on student and professional work from the natural sciences, social sciences, humanities, and applied fields. Designed for active learning and problem-based approaches as well as for more traditional approaches, the book now includes more examples from real student research projects and adds more tables and figures to enliven the discussion.
