When three, four or five people gather to solve a problem, chances are they will succeed beyond the efforts of an equivalent number of individuals working separately, even if those soloists are the brightest available. So conclude researchers at the university of Illinois.
The investigators enrolled 760 of the school's students to solve complex letter and word problems. Some toiled as individuals while others functioned in-group of two, three, four or five. The groups of three, four and five performed better than any set of individuals. The dynamic is sensitive, however. Teams of two performed at the same level as two separate people, suggesting that this team size is too small to foster the dynamics that create optimal problem solving. Also interesting is that groups of three, four and five did equally well compared with one another; there was no advantage to adding people beyond a trio. Study leader Patrick R. Laughlin says that in addition to tackling workplace challenges, problem-solving groups might enhance classroom learning. Further research is needed to determine whether student groups perform better than individuals do in academic settings and, if so, at what ages and test. Happy Learning, Yovan P. Putra
