Based on Self-Determination Theory (Deci & Ryan, 2000), this study tested whether changes in autonomous motivation toward physical education (AMPE) during the transition from elementary to secondary school can be predicted by changes in perceived need support from the physical education (PE) teacher and perceived physical school environment.…

Though video games are commonly considered to hold great potential as learning environments, their effectiveness as a teaching tool has yet to be determined. One reason for this is that researchers often run into the problem of multicollinearity between prior knowledge, in-game performance, and posttest scores, thereby making the determination of…

Students with emotional and/or behavioral disabilities (E/BD), including students with emotional disturbance and attention deficit hyperactivity disorder, receiving special education services perform significantly worse on academic performance measures than same age peers. Researchers have focused on reading and math performance while less is…

Some intensive quantities, such as slope, velocity, or likelihood, are perceptually privileged in the sense that they are experienced as holistic, irreducible sensations. However, the formal expression of these quantities uses "a/b" analytic metrics; for example, the slope of a line is the quotient of its rise and run. Thus, whereas students'…

This study investigates how a variety of resources mediated collaborative problem solving for a group of preservice teachers. The participants in this study completed mathematical, combinatorial tasks and then watched a video of a sixth grader as he exhibited sophisticated reasoning to recognize the isomorphic structure of these problems. The…

In this article, the authors examine whether delayed substance initiation during adolescence, achieved through universal family-focused interventions conducted in middle school, can reduce problematic substance use during young adulthood. Sixth-grade students enrolled in 33 rural midwestern schools and their families were randomly assigned to 3…
