Technical writing teachers who believe in the fundamental value of group work and its potential for helping students preevaluate their papers must deal with the problems associated with the technique by adding structure to student efforts in the areas of group training, group activities, and group evaluation. Explicitly training students to preevaluate papers lets them know the teacher's standards, gives the teacher the chance to demonstrate and discuss appropriate and inappropriate group interaction behaviors, and shows the students that constructive criticism of a paper need not be devastating. Grading criteria sheets and role playing are two structures that also help groups to succeed. Finally, evaluation of the group process itself by both the students and the teacher gives the students the feedback they need to function as a group. (Appendixes include descriptions of group members' and group leaders' roles, an evaluation criteria sheet, a role playing scenario, and a group evaluation form.) (JL)
