未知题型Are two heads usually better than one? If you had a difficult problem to
solve, would you be better working on the problem alone or working on it as S1.______
part of a group? Years of research has yielded a consistent pattern of findings
shows 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 be
outweighed unless efficiency in terms of time per person is a major criterion. S9.______
