Guided by an expectancy-value model of achievement choice (Eccles et al., 1983; Wigfield & Eccles, 2000), the relationships among expectancy-related beliefs, subjective task values (importance, interest, and usefulness), and achievement outcomes (intention, engagement, and performance) were examined in a college-level beginning weight training class. A total of 156 students (73 males, 83 females) completed questionnaires assessing their expectancy-related beliefs, subjective task values, and intention for future participation. Their engagement was measured via self-recorded workout log entries in class, and their performance was determined by two skill tests. Results of the study supported the application of the expectancy-value model in the context of a college weight training class. Importance and interest were significant predictors of intention and engagement, whereas expectancy-related beliefs emerged as the only predictor of performance. Males reported higher scores on expectancy-related beliefs and performed better than females.
