Problem-based learning (PBL) is a student-centered educational approach that emphasizes collaborative group work to solve complex, real-world problems, therefore enhancing motivation and self-directed learning. Originating in the 1960s at McMaster University for medical education, PBL aims to improve essential skills such as teamwork and communication. Key components include real-world problems, the role of the teacher as a facilitator, and fostering critical thinking and collaboration among students.
