The instructor reads each question, one at a time, from Box 5.5. After each question is read, the class is asked to point out its flaws. All members of the class are then given two minutes to come up with a revised version of the question. Individual students are called on to produce their revised versions, which are written on the board/screen. The class is then asked to comment on whether the revised versions solve all the problems contained in the original question, or if further revision would be appropriate.
