“…Academic engagement is viewed as a keystone behavior, which refers to behaviors that have broad and widespread benefits for students in current and future environments (Barnett, 2005). Keystone behaviors, like academic engagement, are typically incompatible with maladaptive and antisocial behaviors (e.g., it is difficult to be engaged with a task and disruptive at the same time) and, when improved, can positively influence academic outcomes, interpersonal relationships, and the classroom or school environment for other students (DiGangi et al, 1991;DuPaul et al, 1998;Greenwood, 1996;Greenwood et al, 1994;McLaughlin et al, 1977;Prater et al, 1992;Wood et al, 1998). Keystone behaviors are attractive targets for intervention given their relative simplicity and their potential impact across multiple domains (Ducharme & Shecter, 2011).…”
