The purpose of the study was to investigate whether the districts that received ongoing training and coaching to use the Active Implementation Frameworks improved mathematics outcomes. The Active Implementation Frameworks represent five essential approaches for effective implementation of any evidence-based program or practice. One of the…

Best practice suggests that curricular decisions be made on the evidence base of the content and the contextual fit of the curriculum to the school setting, and with coaching to help teachers effectively use curricula. Messages from the federal government encourage school administrators and researchers to consider the costs of a program. The…

This study examined whether the efficacy of ROOTS, a 50-lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, differed by group size and whether initial skill moderated intervention effects by group size. The study utilized a randomized block design with at-risk students (n = 1,251) within…

This study examined whether the efficacy of a 50 lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, ROOTS, differed by group size and whether initial skill moderated intervention effects by group size. The study utilized a randomized block design with at-risk students (n = 1,251) within…

A concerning number of students enter kindergarten facing an intractable variation of mathematics difficulties (MD). This study investigated the impact of an explicit, core kindergarten mathematics program on the mathematical outcomes of kindergartners who demonstrated risk for severe MD at kindergarten entry and examined whether these students…

This article presents the results of an evaluation of Positive Family Support, an ecological family intervention and treatment approach to parent supports and family management training developed from a history of basic and translational research. This effectiveness trial, with 41 public middle schools randomly assigned to intervention or control,…

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…

Group size and treatment intensity are understudied topics in mathematics intervention research. This study examined whether the treatment intensity and overall intervention effects of an empirically validated Tier 2 mathematics intervention varied between intervention groups with 2:1 and 5:1 student-teacher ratios. Student practice opportunities…

One commonly used strategy used in attempts to decrease racial disproportionality in school discipline across the country is sharing data with school administrators that discipline disparities are a problem in their schools with the assumption that it will increase attention to equity and improve outcomes. The purpose of this study was to assess…

This study evaluated the long-term impact of schoolwide positive behavioural interventions and supports (PBIS) on student academic achievement. In this quasi-experimental study, academic achievement data were collected over 9 years. The 21 elementary, middle, and high schools that achieved moderate to high fidelity to the Save & Civil Schools'…

We report on a practitioner implementation of Fusion, a first-grade mathematics intervention. Studies such as this evaluation of a loose implementation under realistic conditions are important to curriculum developers' understanding of how evidence-based programs and tools work under a variety of implementation scenarios. In this…
