“…When these same rules were provided to the children in an autonomysupportive way (with explanatory rationales, with the acknowledgment of the children's perceptive and feelings), however, children showed no decrease in engagement compared to the children in the control group and greater engagement than children who received the rules presented in a controlling way. Beyond rules, other research has shown essentially the same effects for other elements of structure-including communications, goals, expectations, rewards, and feedback (Deci, Koestner, & Ryan, 1999;Grolnick & Ryan, 1987;Jang, 2009;Ryan, Mims, & Koestner, 1983;Schuh, 2004)-namely, that any element of structure can be presented in either an autonomy-supportive or controlling way and, also, that student outcomes are enhanced when the element of structure is presented in an autonomy-supportive way, yet diminished when the element of structure is presented in a controlling way (Sierens et al, 2009). …”
