This document discusses problem-based learning (PBL) and project-based learning (PBL). PBL is a student-centered approach where students work collaboratively to solve complex, real-world problems. It increases motivation, develops critical thinking skills, and enhances information retention. The seven steps of PBL are analyze, define, clarify, identify learning objectives, self-study, review, and report. Project-based learning engages students in sustained investigations of authentic problems. It emphasizes learner-centered environments, collaboration, authentic tasks, and innovative assessment. Benefits include improved learning strategies, academic gains, and development of complex skills like problem-solving.
