 Most teachers ask questions during a lesson, and that's good, because it's important to involve the students rather than just giving them the information. But the kind of questions that the teachers ask is the most important thing. Some teachers only ask questions about facts, and students give answers that they have memorized. But in a question-and-answer strategy, a new element is added, called critical thinking. In this strategy, we can ask questions and get students to think more deeply. The focus is on thinking, not just memorizing. So in the question-and-answer strategy, we ask three kinds of questions to get the students involved in the lesson. The first kind of question is about facts about the lesson. The second kind of question makes the students think about the lesson. And the third kind of question helps the students relate the lesson to their own lives. We use questions that go beyond yes and no answers and just getting the facts to get the students to think more deeply.
