Self-regulated and externally regulated learning in adolescence: Developmental trajectories and relations with teacher behavior, parent behavior, and academic achievement.

= 0.71, 51.75% female) addressed these gaps. Results from multilevel latent basic growth curve models showed that self- and externally regulated learning decreased over the 5 years at both the individual student and the class level. Changes in self- and externally regulated learning were linked: Classes with higher levels of self-regulated learning at Grade 5 showed a stronger decrease in externally regulated learning over time. Initial levels of and changes in student-reported teacher and parental autonomy support and achievement pressure were associated with self- and externally regulated learning at the individual student level; student-reported teacher autonomy support and self-regulated learning were also linked at the class level. Self-regulated learning related positively to standardized achievement test scores but not to adolescents' grades. This study adds to the scarce evidence base on different regulatory forms of adolescents' learning and can inform future research on adolescents' positive development and educational practice.
