“…However, learning environment and educational effectiveness studies as well as studies on student motivation and current motivation theories such as the self-determination theory (SDT; Ryan and Deci, 2000 , 2020 ; Deci and Ryan, 2002 ) and stage–environment fit theory ( Eccles and Roeser, 2009 ) refer to learning environment experiences (such as teacher behavior, teacher–student interaction, peer group characteristics, and interactions between peers) as important additional explanations for students’ adaptive functioning/behavior, e.g., academic engagement ( Ryan and Patrick, 2001 ; Urdan and Schoenfelder, 2006 ; Roorda et al, 2011 ; Vansteenkiste et al, 2012 ; Wang and Eccles, 2012b ; Stroet et al, 2013 ; León et al, 2017 ; Opdenakker, 2020 ) and maladaptive functioning/behavior such as procrastination, misconduct, problem, or antisocial behavior in the classroom ( O’Connor et al, 2011 ; Vansteenkiste et al, 2012 ; Nordby et al, 2017 ; Oostdam et al, 2019 ; Opdenakker, 2020 ). Moreover, there is evidence from longitudinal studies on students’ motivation and academic engagement in school that, in general, students’ motivation and academic engagement not only decline during secondary education ( Gottfried et al, 2001 ; Wigfield et al, 2006a , b ; Skinner et al, 2008 ; van der Werf et al, 2008 ; Peetsma and van der Veen, 2011 ; Opdenakker et al, 2012 ; Wang and Eccles, 2012a ) but also that students’ learning environment experiences affect (the evolution of) their motivation and academic engagement in school ( Opdenakker et al, 2012 ; Wang and Eccles, 2012b ; Stroet et al, 2015 ; Núñez and León, 2019 ).…”
