Based on an examination of the use of case method in Information Unit Management courses, this study aims to demonstrate the significant influence of this approach as a valid methodology for teaching courses in the School of Library and Information Science. Researchers conclude that the case method is effective: it not only significantly improves the quantitative results of learning; but also, from a qualitative standpoint, enriches the teaching/learning experience through improved communication with students, while encouraging critical thinking and better overall engagement with curricular objectives. The paper also offers a historical overview of the case method, key definitions and features, steps for implementation and several case studies to support the theoretical context and foundations of the research.
