Using specific classroom scenarios, teachers explore characteristics and benefits of ProjectBased Learning (PBL). Throughout the course, teachers consider their own teaching practice as they follow a teacher new to project-based learning who discusses strategies with a mentor teacher. They also consider the ways that technology supports project-based approaches. Planning and project design modules guide teachers through organizing the curriculum, the classroom, technology, and students for successful 21st century projects. The assessment module demonstrates strategies for assessing students’ 21st century skills throughout an open-ended project. The course offers opportunities to apply the PBL concepts with action planning exercises.
