In the past several years, questioning has rightly earned a higher degree of importance in the inquiry process. Good preparation before beginning inquiry often determines how successful students are, especially in the early stages. Determining the questions that need answered brings focus to the process of inquiry. And teaching students the skills and importance of asking good questions provides a solid foundation for learning.
In the classroom, teachers need to model good questioning techniques. Students need many opportunities to practice and develop good questioning skills. They need to understand the purpose behind the essential questions they are asking, and that those questions may need to be modified as they discover new knowledge.
