This document discusses important questioning skills for teachers to generate interaction among students, such as varying question types, calling on non-volunteers, rephrasing questions, and allowing sufficient time for students to respond. It emphasizes asking open-ended, higher-order thinking questions and providing feedback to students. Teachers should know their own questioning style, increase their repertoire of question types, and consider students' abilities when asking questions to improve their technique. Encouraging students to ask questions also promotes participation and curiosity.
