This document provides an overview of project-based learning (PBL), including what it is, why it is used, and how to plan a PBL unit. PBL involves students collaborating over an extended period of time to solve an authentic, real-world problem. Unlike short-term projects, PBL incorporates multiple subjects and standards. The document lists several benefits of PBL, such as increasing student engagement and improving learning outcomes. It also outlines the basic steps to planning a PBL unit, which includes identifying a driving question, relevant content and standards, and determining an appropriate final product and audience. Examples of possible driving questions, products, and audiences are also provided.
