Once all the envelopes are picked up, they are redistributed to different groups for grading. Each group picks a captain. The captain is responsible for recording, on a form provided, the Social Security number of the grader and the Social Security number of the papers they are taking home to grade. When students return the next class session, they record the grades on these same forms. Forms are turned in every four weeks.
Groups have some flexibility in how many papers each student takes to grade.
Some groups will choose to have one person grade all the papers, thus they grade one week on and four off. The first few weeks it is important to let each group have time to learn these procedures from each other, and to generate questions. After a few times through, paper exchanging can be done in five minutes or less. Then, I let students visit for a few minutes. This last step is most important for I am discovering that a few minutes of free time deepens their connection to each other, improves attendance, and warms the class milieu.
