This document outlines the steps of problem-based learning, including defining ill-structured real-world problems, organizing students into teams to research problems and test solutions, and presenting their findings. It contrasts well-structured textbook problems with ill-structured problems that more closely mirror real life. Effective problem-based learning engages students by posing meaningful problems, allowing them to develop and assess multiple solutions through hands-on modeling and strategy techniques like brainstorming and decision making.
