"In the learning environments of classrooms and schools, students are exposed to and perceive various messages about the purposes of achievment. For example, students can perceive that in their classroom or school, there is an emphasis on learning, understanding, and improvment (a mastery goal structure). Similarly, they can perceive messages that suggest that getting the highest grades on the test and outperforming their classmates are valued most in the classroom or school (a performance goal structure). Sometimes, these perceptions are influenced by teacher practices that emphasize a mastery or performance goal structure, such as when teachers post only the work of the highest achieving students in the class (performance-goal-oriented instructional practices)."
