Suchman believes students are naturally motivated to solve this puzzle. After presenting the problem statement, the students begin to ask the teacher questions. The teacher only answers yes and no questions. The students quickly learn to pose their questions as yes or no questions if they want them answered. They are gathering data and verifying the problem, formally or informally.
Students then start to form hypotheses and experiment by posing their hypotheses in their questions.
I have observed a resourceful teacher who works his science lessons backwards using the inquiry training model. The teacher then allowed yes and no questions until the materials and procedures were determined by the students. Then the students conducted their own experiments. The students seemed so much more motivated and actively involved in their work than I've seen using more traditional lock-step fashion direct teachingapproaches. I am currently having great fun introducing my second graders to inquiry training using my pregnancy as a problem statement.
