The document discusses questioning techniques used in classrooms. It notes that the majority of questions asked by teachers are closed questions, are answered by the teacher, and are used to assess understanding rather than challenge thinking. On average, teachers ask 1-2 questions per minute, over 70,000 questions per year. In primary schools, 57% of questions are managerial and 35% are lower-order recall questions. In secondary schools, only 4% of questions are higher-order. The document advocates using open-ended questions that require more thought, as well as wait time to allow students to think before answering. It provides Bloom's Taxonomy as a framework for questioning at different levels of thinking.
