There is nothing more futile than the attempt to accomplish a task when one has not yet decided what the task is. Likewise, there is nothing more difficult than a teacher's attempt to teach a set of skills when the teacher has not yet decided what the skills are.

Yet he must have a clear understanding of these thinking skills if he is to instill them in his students.
