“…Under the right conditions, people working or studying in teams can produce, learn, innovate, and solve problems more effectively than individuals working alone (Hill, 1982;Holter, 1994;Jones, 1996;Larson & LaFasto, 1989;Martell & Borg, 1993;Peters, 1987;Piczak & Hauser, 1996;Wellins, Bynam, & Wilson, 1991).
