This article examines the classroom learning environment in relation to achievement goal theory of motivation. Classroom structures are described in terms of how they make different types of achievement goals salient and as a consequence elicit qualitatively different patterns of motivation. Task, evaluation and recognition, and authority dimensions of classrooms are presented as examples of structures that can influence children's orientation toward different achievement goals. Central to the thesis of this article is a perspective that argues for an identification of classroom structures that can contribute to a mastery orientation, a systematic analysis of these structures, and a determination of how these structures relate to each other. The ways in which interventions must address the independency among these structures are discussed in terms of how they influence student motivation.
