The objective of this study was to investigate how different components of achievement goal theory were related to each other and to students' motivation, cognitive engagement, and achievement in mathematics. Junior high school students (N=525) completed a self-report survey that assessed their perceived classroom goal structures; personal goal orientations: and a collection of outcomes that included persistence, procrastination, choice, their use of cognitive and metacognitive learning strategies, and mathematics grade. Results indicate that mastery structure and mastery orientation were related to adaptive outcomes in all areas. The patterns of relations for performance-approach goal structure, and for performance-approach and performance-avoidance goal orientations were less uniform across outcomes. Implications for achievement goal theory and future research are discussed.
