When to use it: When teachers want to guide their students into higher-ordered thinking. Note: research suggests that teachers simply asking students higher-order questions in isolation is not effective, but asking students a series of linked questions that help students think critically about content creates higher-ordered thinking.
What it encourages: It encourages students to accurately elaborate on content, make inferences, and pushes higher order thinking thinking about topics and content.
How to use it: The teacher use an sequence of increasingly complex questions that require students to critically think about the content.
