The document discusses the nature and importance of questioning in the classroom. It states that questioning is a major form of human communication and an important part of the teaching and learning process, as it develops critical thinking skills. Effective questioning requires forming clear, relevant questions at varying levels of difficulty according to students' ages and abilities. Questions should check prior knowledge, evaluate understanding, and promote higher-order thinking like analysis and problem-solving. Lower-level questions often have single, factual answers, while higher-level questions have open-ended answers requiring thought and engagement. Proper questioning creates a language-rich environment, reviews lessons, and encourages student motivation and involvement.
