Recognizing this, in this article I argue that students’ classroom engagement depends, in part, on the supportive quality of the classroom climate in which they learn. According to the dialectical framework within self‐determination theory, students possess inner motivational resources that classroom conditions can support or frustrate. When teachers find ways to nurture these inner resources, they adopt an autonomy‐supportive motivating style. After articulating what autonomy‐supportive teachers say and do during instruction, I discuss 3 points: teachers can learn how to be more autonomy supportive toward students; teachers most engage students when they offer high levels of both autonomy support and structure; and an autonomy‐supportive motivating style is an important element to a high‐quality teacher‐student relationship.")
