Educational and psychological research often involves comparing motivation across groups. It is critical to ensure that observed differences in motivation are true variations by group, not due to measurement biases. With a diverse sample of undergraduate students (N = 2200), this study measured internal consistency and gathered validity evidence…

In this commentary, we complement other constructive critiques of educational randomized control trials (RCTs) by calling attention to the commonly ignored role of context in causal mechanisms undergirding educational phenomena. We argue that evidence for the central role of context in causal mechanisms challenges the assumption that RCT findings…

Students' success in undergraduate STEM courses requires effective studying behavior, but also the motivation to enact it. Promoting students' achievement in STEM has commonly focused on either study strategies (cognitive) or motivational interventions; we hypothesized that combinations of these would be more effective. Using a Learning Management…

Expectancy-value theory highlights the roles of students' expectancies, task values, and perceived costs in their motivation and achievement. While ample research has highlighted the positive associations of expectancy beliefs and task values with academic achievement, research on students' perceived costs is in its infancy. We investigated the…

Student cognition and motivation, as well as institutional policies, determine student course grades and retention in science, technology, engineering, and mathematics (STEM) majors. Regarding cognition, study skills relate to course grades, and grades relate to retention in STEM. Several aspects of motivation are related to both grades and…
