When working a mathematical problem, there are many sources of authority a pupil can reference to check the accuracy of their work: As a teacher, I am in the business of developing Independent Problem Solvers. In practice, I nudge students away from the first two sources of authority towards the second two. There is, however, one more authority that I have not mentioned. This final authority is the basis of any scientific journal: the consensus of one's peers. Students can access the authority of their peers when they are forced to discuss their answers with their classmates. Practically, I assign several book problems during class and tell students to work independently. After five to ten minutes, I interrupt the class. I tell them that they will have to combine all of their answers onto a single sheet that they will turn in. Each group is given a large sheet of paper already sectioned-off and numbered. There is one region for each of the assigned book problems. It is the groups' responsibility to agree on which work and answer to put on the one sheet they submit together. The combined pressures of needing to submit their work and to work together gets the students arguing about the correct solution to each problem - exactly what I want.
