This document discusses project-based learning (PBL). It defines PBL as a comprehensive, deep learning approach where students investigate authentic problems. PBL involves students working to solve problems, often in groups, and results in an end product. It is student-centered with teachers taking an advisory role. PBL is organized around open-ended challenges, requires skills like critical thinking and collaboration, allows some student choice, and results in a public presentation. It emphasizes long-term, interdisciplinary work and differs from traditional learning by having students manage their own work and time. PBL relies on student groups determining their own projects. Benefits include improved motivation, satisfaction, and development of integrated understanding when applying principles to real-life problems
