“…The literature from these separate but overlapping traditions has identified teacher practices that are associated with the self-fulfilling prophesy effect (Rosenthal & Jacobson, 1968) and with students' academic motivation and perceived competence (Dweck & Leggett, 1988;Lüdtke, Köller, Marsh, & Trautwein, 2005;Urdan, Midgley, & Anderman, 1998). These practices, collectively referred to in the teacher expectancy literature as high-differentiating practices, include providing more emotional support, choice, praise, response opportunities, and special privileges to high achievers and more criticism and direction to low achievers; frequent classroom reminders of the importance of not making mistakes and of earning good grades; more frequent and more public performance feedback (Brophy, 1983;Jussim, 1986;Mac Iver, 1988;Weinstein et al, 1987), and grading in reference to comparison with others rather than in relation to personal improvement (Marsh & Craven, 2002).…”
