Questioning is a critical skill for teachers as it is the primary method of interaction, assessment of learning, and providing appropriate challenges. Effective questioning reinforces learning objectives, involves all pupils, and engages pupils in higher-order thinking like justification and reasoning. It is easy for teachers to fall into pitfalls like an overreliance on closed questions, not giving pupils time to think, and not involving the whole class. Teachers should evaluate their own questioning techniques using recordings and focus on balancing open and closed questions as well as handling incorrect answers effectively.
