The amount of merit-based scholarship support for graduate students in the United States has increased dramatically. Given this increased investment, does increasing the size of scholarships awarded to the most academically able admitted students substantially increase their probability of enrollment? We found no support for a positive answer to…

The summer after high school graduation is a largely unexamined stage of college access among underrepresented populations in higher education. Yet two recent studies revealed that anywhere from 10% to 40% of low-income students who have been accepted to college and signaled their intent to enroll reconsider where, and even whether, to matriculate…

Early college high schools are a new and rapidly spreading model that merges the high school and college experiences and that is designed to increase the number of students who graduate from high school and enroll and succeed in postsecondary education. This article presents results from a federally funded experimental study of the impact of the…

In some experimental evaluations of classroom-level interventions it is not practically feasible to randomly assign teachers to experimental conditions. Given such restrictions, researchers may randomly assign students to experimental conditions and consider the teacher to be a part of the intervention. However, in an individually randomized…

This large-scale, experimental study aimed to (a) describe the extent to which teachers of preschool children at risk for reading difficulties make references to print during whole-class, shared-book read alouds and (b) empirically test the extent to which participation in professional development influences teachers' frequency of references to…

As an example of how the effectiveness of well-designed laboratory interventions is often diffused in the field, we examined the effects of a motivation intervention on students' perceptions and learning. The intervention proved to be more effective in the laboratory (g = 0.45) than the field (g = 0.05) in enhancing subsequent motivation. We…

Many postsecondary institutions utilize learning communities to increase social engagement and attachment to the college community. In recent years, these communities have proliferated as part of a trend fueled by low retention and persistence rates, increasing reluctance of 4-year institutions to provide remedial education, and pressure on…
