I hear and I forget.  I see and I remember.  I do and I understand. 

Project based learning is a teaching method that enables students to learn through experience by tackling a wide variety of real-world challenges and projects. It emphasizes learning activities that are long-term, often team-based, interdisciplinary, and student-centered. It is designed to help our students acquire a deeper understanding of their subject by taking the theory that is learned in the lecture theatre and providing an opportunity to put it into practice through experimentation.
