"What boosts PBL from a fun and engaging exercise to a rigorous and powerful real-world learning experience? Researchers have identified four key components that are critical to teaching successfully with PBL (Barron & Darling-Hammond, 2008; Ertmer & Simons, 2005; Mergendoller & Thomas, 2005; Hung, 2008). All of these play a role in the curriculum-design process."
A Review of Research on Inquiry-Based and Cooperative Learning
By Dr. Brigid Barron and Dr. Linda Darling-Hammond, Stanford University
"Decades of research illustrate the benefits of inquiry-based and
cooperative learning to help students develop the knowledge and skills necessary to be successful in a rapidly changing world."
You know the hardest thing about teaching with project-based learning? Explaining it to someone. It seems to me that whenever I asked someone the definition of PBL, the description was always so complicated that my eyes would begin to glaze over immediately. So to help you in your own musings, I've devised an elevator speech to help you clearly see what's it all about.
