POGIL is both a philosophy and a strategy for teaching and learning. It is a philosophy because it encompasses specific ideas about the nature of the learning process and the expected outcomes. It is a strategy because it provides a specific methodology and structure to achieve these outcomes that are consistent with the way people learn. The motivation for implementing POGIL, the research base that supports it, and the design of POGIL activities will be described. Student outcomes data that document the success of POGIL will be presented.
