Years of research has yielded a consistent pattern of findingsshows that groups typically produce more, and produce better solutions to S2.______problems than the same number as individuals working alone. For instance, a S3.______classic experiment by Shaw had groups or individual subjects attempted to S4.______solve problems involving conceptual and mathematical skill. In every case, S5.______the groups produced more correct solutions than the individuals.However, it was one important warning to the finding of group superiority: S6.______the groups were considerably less efficient, when time considered, than the S7.______individuals were. In other words, although groups produced more correct solutions,but they did so at a cost of more time. In fact, much subsequent S8.______research has suggested that the advantage of groups in solving problems can beoutweighed unless efficiency in terms of time per person is a major criterion. S9.______
