The results for math course type also support the premise that self-reported strategy use and motivation processes are more closely related to student achievement in more intensive academic settings. In short, these processes clearly distinguished high achievers (i.e., an A-or higher) from those attaining less success in academically rigorous advanced math classes across both regulatory measures as well as task interest and self-standards. The observed effect sizes across these variables were medium to large. Conversely, when examining these trends for the students in regular math courses, higher achievers were distinguished from the less successful students across only task interest and self-standards and these effects were only small to medium. Based on these findings, the relationship between self-reported self-regulation strategy use and motivation variables with math achievement was stronger in contexts that were operationally defined to be more academically rigorous and demanding. However, as pointed out earlier, simply enrolling in these more challenging learning environments does not mean that students, on average, will spontaneously exhibit more adaptive regulatory and motivation skills than those in regular classes.
