Higher level questioning involves asking students questions that require them to think beyond simply recalling facts and instead apply, analyze, synthesize, and evaluate information. Such questions promote critical thinking skills. Research shows that higher order questioning can strengthen students' brains by increasing neural branching and overcoming the tendency to develop routine patterns of thinking. Teachers can use taxonomies like Bloom's Revised Taxonomy or Webb's Depth of Knowledge to structure higher level questions. Strategies for applying higher level questioning include posing provocative questions, problems with multiple solutions, concept mapping, and Socratic dialogues.
