"Students are hungry for learning that matters. Project based learning has students involved in explaining their answers to real-life questions or challenges. A project's driving question or challenge is so deep that it requires students to create an end product and share their conclusions with others. Instead of traditional projects that come at the end of a unit of study, project-based learning has the project introduced at the beginning of the unit. The project gives students a reason for learning the content and a venue for practicing 21st century skills."
