Informed by achievement goal orientation and self-determination theories, we explored the role of cultural/contextual factors on Korean students' achievement motivation. Specifically, we examined the role of the Korean middle school students' family orientation as a mediator between their perceptions of parent goals or motivating styles and their achievement motivations in learning math, when their perceptions of classroom goal structures were controlled. We also investigated gender differences in the role of the students' family orientation and of their perceptions of their parents and classroom variables in predicting their own achievement motivations. Multi-sample path analyses indicated that both Korean boys' and girls' family orientation mediated between their perceptions of parent variables and their own achievement motivations. Korean students' family orientation predicted mainly controlled forms of motivation and ego-focused goals. In addition, the relationships between students' perceptions of parent variables and their achievement motivations statistically varied across gender. (Contains 2 figures and 2 tables.)
