This document provides an overview of various inquiry and information process models that can be used to guide student research. It describes models such as the Big6, Carol Kuhlthau's Information Search Process, and the Savvy Seven Research Model. Each model breaks the research process down into steps or stages to help students comprehend the task and strategies needed. The document emphasizes that the models are flexible and iterative - students may need to move back and forth between steps as new questions or understandings emerge during research. An effective model provides a common language and scaffolding for students while allowing for recursion as understanding develops.
