Problem-based learning (PBL) is an educational approach that uses real world problems as a context for students to learn about basic and clinical sciences. In PBL, students work in small groups facilitated by a tutor to discuss and solve clinical problems. This allows students to identify gaps in their knowledge and develop self-directed learning skills. PBL aims to develop an integrated, context-specific knowledge base and skills in critical thinking, self-directed learning, collaboration and communication. Some potential advantages of PBL include greater relevance to medical practice and improved knowledge retention and application.
