Learning is more effective when done collaboratively. In generations past there was a taboo about working in groups; school work was supposed to be done individually. Research from Richard Light of Harvard unequivocally indicates that students working collaboratively learn more effectively, and are far more likely to achieve their academic goals (such as graduating from college and attending graduate school). His study, which consisted of in-depth interviews with over 1,600 college students, found virtually all struggling students shared one key trait: they tended to study alone. Collaboration can be the difference between a lackluster performance and a fully engaged student.
