There are large gaps in reading skills by family income among school-aged children in the United States. Correlational evidence suggests that reading skills are strongly related to the amount of reading students do outside of school. Experimental evidence testing whether this relationship is causal is lacking. We report the results from a…

The College Possible program provides intensive coaching by near-peer mentors, peer group support, and opportunities for academic and non-cognitive skill building to low-income students through an intensive two-year curriculum in junior and senior years of high school. The goal of the program is to close the achievement gap between low-income…

In this paper, we report results from a multisite, student-level randomized controlled trial that examined the impact of the Building Assets, Reducing Risks (BARR) model on ninth-grade students. The BARR model is a comprehensive, strength-based approach that uses eight interlocking strategies to build intentional staff-to-staff, staff-to-student,…

We investigated students' academic achievement in three high-enrollment, introductory-level history sections at a large, public, Hispanic-serving university. Using a conditional indirect-effects model, we analyzed supplemental instruction (SI) attendance and class absences as predictors of course success, after accounting for sex, ethnicity/race,…

Using a dataset containing nearly 500,000 courses taken by over 40,000 community and technical college students in Washington State, this study examines the performance gap between online and face-to-face courses and how the size of that gap differs across student subgroups and academic subject areas. While all types of students in the study…

The purpose of this study was to investigate whether participating in science, technology, engineering, and mathematics (STEM) project-based learning (PBL) activities effected students who had varied performance levels and to what extent students' individual factors influenced their mathematics achievement. STEM PBL has been a critical challenge…

At the college level, the effectiveness of active-learning interventions is typically measured at the broadest scales: the achievement or retention of all students in a course. Coarse-grained measures like these cannot inform instructors about an intervention's relative effectiveness for the different student populations in their classrooms or…
