This document discusses ways for teachers to challenge students and encourage progress through questioning techniques. It provides examples of open-ended questions teachers can pose to students at the start of lessons to stimulate thinking on different levels of challenge. It also offers strategies for questioning students during lessons, such as planning questions in advance and using techniques like posing, pausing, bouncing and pouncing. The document emphasizes making questions an important part of the classroom by modeling questioning, providing opportunities for students to practice, and responding positively to student answers rather than just saying if they are right or wrong.
