A teacher should aim to provide the questions that will lead the student into the understanding cycle. Asking questions at the right time is a critical role of a good teacher. This statement summarizes what we call the sounding board model of teaching. When teachers adopt the role of sounding boards, they should allow students to speculate, wonder, imagine, and be creative. However, it is rather difficult for teachers to be effective sounding boards.
Teachers like to tell the correct answers to students.
Teachers do not have the time to sit with students, and encourage them to pursue the implications of what they are thinking. Additionally, teachers often fall into the trap of thinking they are asking questions when they are really only delivering answers using the syntactic guise of a question.
