The document discusses problem-based learning (PBL) in social studies education. PBL is defined as organizing learning around ill-structured problems so that students simultaneously acquire new knowledge and experience in wrestling with problems. Key characteristics of PBL include using an actual or simulated problem situation, problems having no clear solution, and students working on problems that require more work than one person can do alone. The document provides examples of PBL activities and driving questions, and outlines six steps for implementing PBL in the classroom, including developing a driving question, creating performance tasks, and determining available resources.
