The research presented in this article integrates 3 theoretical perspectives in the field of motivation: expectancy-value, achievement goals, and interest. The authors examined the antecedents (initial interest, achievement goals) and consequences (interest, performance) of task value judgments in 2 learning contexts: a college classroom and a high school sports camp. The pattern of findings was consistent across both learning contexts. Initial interest and mastery goals predicted subsequent interest, and task values mediated these relationships. Performance-approach goals and utility value predicted actual performance as indexed by final course grade (classroom) and coach ratings of performance (sports camp). Implications for theories of motivation are discussed. (Contains 5 tables and 7 figures.)
