“…Generally, students are responsive to the effects of these different styles (for a review, see Deci & Ryan, 1987;Deci, Vallerand, Pelletier, & Ryan, 1991;Reeve, 1996Reeve, , 2002. For example, students of autonomy-supportive teachers, compared to students of relatively controlling teachers, show greater perceived competence (e.g., Deci et al 1981;Ryan & Grolnick, 1986;Trouilloud et al, 2006), intrinsic motivation (e.g., Deci, Nezlek, & Sheinman, 1981), creativity (e.g., Amabile, 1979;Koestner, Ryan, Bernieri, & Holt, 1984), preference for optimal challenge (e.g., Harter, 1978;Pittman, Emery, & Boggiano, 1982;Shapira, 1976), conceptual understanding (e.g., Benware & Deci, 1984;Boggiano, Flink, Shields, Seelbach, & Barrett, 1993;Flink, Boggiano, & Barrett, 1990), positive emotionality (e.g., Ryan & Connell, 1989), and academic performance (e.g., Boggiano et al, 1993;Flink, Boggiano, & Barrett, 1990), and are less likely to drop out from school (Vallerand et al, 1997). In turn, student self-determined motivation predicts leisuretime physical activity intentions (e.g., Ntoumanis, 2001;Standage, Duda, & Ntoumanis, 2003), preference for optimally difficult tasks (e.g., Standage, Duda, & Ntoumanis, 2003), concentration (e.g., Ntoumanis, 2005) and effort (e.g., Ntoumanis, 2001) in the class.…”
