This study examines the effectiveness of scaling up a vocabulary intervention, pre-K-first grade, using a structured adaptation of the World of Words that allowed teachers some autonomy over its implementation. The purpose was to determine whether such an adaptation could maintain fidelity and promote positive child outcomes. Classrooms (pre-K…

Most students who begin at a community college leave without earning a degree. Given the growing emphasis on student success, many colleges have implemented re-enrollment campaigns designed to foster re-engagement and degree completion among former students. However, there is a lack of causal evidence on their effectiveness. We implement a text…

We assessed the effects of a whole-school equity intervention implemented within a school-wide positive behavioral interventions and supports (PBIS) framework on racial inequities in school discipline in eight elementary schools with inequitable referrals for Black students. The intervention involved assessing patterns of racial disparities in…

Students in the elementary grades often experience difficulty setting up and solving word problems. Using an equation to represent the structure of the problem serves as an effective tool for solving word problems, but students may require specific pre-algebraic reasoning instruction about the equal sign as a relational symbol to set up and solve…

This study investigated the effectiveness of the Model of Reading Engagement (MORE), a content literacy intervention, on first graders' science domain knowledge, reading engagement, and reading comprehension. The MORE intervention emphasizes the role of domain knowledge and reading engagement in supporting reading comprehension. MORE lessons…

In this methodological illustration, we examined Tier 2 social skills interventions to support school success for students with or at risk for emotional or behavior disorders. We presented findings examining the usability and feasibility of the "Social Skills Improvement System-Intervention Guide" and "Positive Action Counselor's…

This article presents an independent large-scale experimental evaluation of two online goal-setting interventions. Both interventions are based on promising findings from the field of social psychology. Approximately 1,400 first-year undergraduate students at a large Canadian university were randomly assigned to complete one of two online…

In 2013, the NYC Leadership Academy (NYCLA) developed a leadership intervention--the Targeted Intensive School Support (TISS) program--in collaboration with the New York City Department of Education (NYC DOE) to support schools that were facing particular challenges. NYCLA asked the RAND Corporation to provide an independent evaluation of the…

The purpose of this project evaluation was to assess the impact of data-based individualization (DBI) on the mathematics achievement of students with intensive mathematics learning needs, including students with disabilities. The evaluation study used a cluster randomized trial in which elementary schools were randomly assigned to treatment using…

There is a need for empirically based educational practices shown to support learning, yet validation tends to require a high degree of experimental control that can limit ecological validity and translation to classrooms. We describe our iterative intervention design to support preschoolers' vocabulary through book reading coupled with playful…

In this report, the authors present the results of a long-term tracking study that follows 1,177 students who applied to enter 1 of 13 oversubscribed Knowledge Is Power Program (KIPP) middle schools through a 5th or 6th grade admissions lottery in 2008 or 2009. Those students are now old enough to have attended college for at least two years. This…

The purpose of this study was to determine the effectiveness of Get the Picture?! in improving the overall college/career readiness of 900 students with disabilities in each of the nine participating treatment high schools in nine rural, high poverty Kentucky school districts after four years of implementation. This quasi-experimental study…

We examine the efficacy of an intervention to improve word reading and reading comprehension in fourth- and fifth-grade students with significant reading problems. Using a randomized control trial design, we compare the fourth- and fifth-grade reading outcomes of students with severe reading difficulties who were provided a researcher-developed…

Problem behaviors are prevalent in schools and may result in negative effects for the students exhibiting those behaviors, teachers, and other students. Increasing on-task behaviors has been shown to minimize disruptive behaviors. The current study utilized an interdependent group contingency-based intervention, Class-Wide Function-related…

Objective: There are currently no empirically-supported, comprehensive school-based interventions (CSBIs) for children with autism spectrum disorder (ASD) without concomitant intellectual and language disability. This study compared outcomes for a CSBI (schoolMAX) to typical educational programming (services-as-usual [SAU]) for these children.…
