Unfortunately, most students ask virtually none of these thought-stimulating types of questions. Most teachers in turn are not themselves generators of questions and answers of their own, that is, are not seriously engaged in thinking through or rethinking through their own subjects. Rather, they are purveyors of the questions and answers of others-usually those of a textbook. We must continually remind ourselves that thinking begins with respect to some content only when questions are generated by both teachers and students. No questions equals no understanding.
Superficial questions equals superficial understanding.
Most students typically have no questions. Hence, the questions they do have tend to be superficial and ill-informed. This demonstrates that most of the time they are not thinking through the content they are presumed to be learning. This demonstrates that most of the time they are not learning the content they are presumed to be learning. If we want thinking we must stimulate it with questions that lead students to further questions.
