according to Marcus Guido

There are different kinds of inquiry-based learning, which become decreasingly structured and suit different classrooms:

• Confirmation Inquiry — You give students a question, its answer and the method of reaching this answer. Their goal is to build investigation and critical-thinking skills, learning how the specific method works.

• Structured Inquiry — You give students an open question and an investigation method. They must use the method to craft an evidence-backed conclusion.

• Guided Inquiry — You give students an open question. Typically in groups, they design investigation methods to reach a conclusion.

• Open Inquiry — You give students time and support. They pose original questions that they investigate through their own methods, and eventually present their results to discuss and expand.All About Inquiry-Based Learning: Definition, Benefits and Strategies
