Study groups help students more easily grasp the material from their classes.Studying in groups helps students learn more effectively. More than 20 years of academic research has consistently demonstrated that fact. But what exactly is it about studying with other people that makes it so effective? Through painstaking research, an expert in creativity and everyday conversation at Washington University in St. Louis has identified two patterns of group dynamics that show why group study is optimal. The research is published in the June 2005 Linguistics and Education journal.
