Each cooperative learning group should be carefully selected by the teacher so that a heterogeneous structure allows each student to bring his or her strengths to the group effort.
The teacher then gives the students an assignment, often helping them to divvy up the work that needs to be done so that each individual in the group has a certain role to play. The end goal can only be reached when every member of the group contributes effectively.
The teacher should also spend time modeling how to resolve conflicts in a cooperative learning group.
At the next meeting, each student shared their assigned work. Taken together, the members of the cooperative learning group enriched each other's understanding of the book at hand.
