This article describes a problem-based learning (PBL) project that incorporates active learning into an organizational behavior (OB) course. It describes a six-step process for designing a course around problems that students identify in their work, school, or personal lives. In addition to researching an OB concept to address their problem, students develop a solution plan, carry out objective measurement of results, and engage in structured reflection on project completion. The article suggests some ways to adapt PBL for classes of different sizes or duration and offers some advice to faculty regarding how to structure the project for best results.
