The document discusses effective questioning techniques for teachers to use in the classroom. It begins by explaining that teachers traditionally use questions to check learning and understanding, but should also use more open-ended questions to encourage deeper thinking. It then provides examples of different questioning strategies like "thinking time", "no hands up", and "phone a friend" which give students more time to formulate responses and participate more fully. The document concludes by emphasizing the importance of using higher-order "big questions", "focus questions", and "fat questions" that challenge students to provide more complex, extended answers in order to develop critical thinking skills.
