As the popularity of project-based learning grows, so does the importance of understanding how this instructional approach can support students' learning and development. The authors describe a project-based approach to literacy and social studies instruction that research has shown to be effective. Key characteristics of the approach and illustrations of how those characteristics are enacted in a project-based learning geography unit are identified. In the unit, students develop informational reading and persuasive writing skills and learn key social studies content and skills by engaging in the development of brochures about their local community for an authentic audience. The authors also describe how educators can navigate common challenges that can arise when transitioning to a project-based approach.
