The document provides an overview of inquiry-based learning and different models that can be used to structure student-directed learning projects. It describes inquiry-based learning as a process where students take ownership of their learning by posing their own questions, researching various sources, processing and sharing their findings, and reflecting on what they learned. Several models are outlined, including the inquiry process with 5 steps, variations of inquiry-based projects, a 4 column planner, an inquiry chart, the "Big Six" model of information problem-solving, and a simplified "Super Three" model.
