Project-based learning (PBL) is an approach to K-12 education designed to engage students through solving real-world problems. For example, rather than learning botany, geology, and horticulture in the abstract, students might redesign a community garden. Working in teams, students learn to identify and describe the problems, design solutions, and work together to fix them. Proponents of PBL cite the central role that solving problems and working collaboratively has in students’ further education and careers. It is a skill that extends to their ability to think critically and tackle difficult issues as future productive citizens.
