This study explored whether initial skill moderated outcomes of Promoting Algebra Readiness, a Tier 2 sixth grade mathematics intervention targeting conceptual and procedural knowledge of fractions. The study analyzed data from a quasi-experimental pilot study in which at-risk students (n = 198) were assigned to the treatment or control condition…

Though argumentative writing is a vital skill across diverse content areas and domains, most U.S. students perform below grade level in writing, and teachers are often unprepared to address this shortfall because their training approaches writing as a subspecialty of reading rather than its own unique discipline. Writing instruction and assessment…

This paper reports the outcomes of an experimental evaluation of "Direct Instruction Spoken English (DISE)," an English language curriculum that focuses on developing English speaking, listening, and comprehension skills in English Learners (ELs). Twenty-nine middle schools in three states were randomly assigned to teach "DISE"…

The purpose of this study was to conduct a replication study of a kindergarten mathematics intervention, ROOTS, delivered within the context of a research base core program. In the study, sixty two classrooms were randomly assigned to treatment (ROOTS) or a business as usual control. All classrooms implemented a research based core program (Early…

High-quality Tier 1 instruction is frequently conceptualized as the "foundation" for other tiers of intervention within multi-tiered systems of support (MTSS) models (Gersten et al., 2009). However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness (Hill et al.,…

Instructional interactions that occur between teachers and students around foundational mathematics topics are critical for supporting mathematical proficiency among students with mathematics learning disabilities (MLD). This study investigated whether the initial mathematics skill of 880 kindergarten students at risk for MLD predicted the…

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…

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 severe MD at kindergarten entry and examined whether these students improved…

This paper describes "the development and technical adequacy of the Classroom Observations of Student Teacher Interactions (COSTI) instrument," a tool for measuring the frequency and rate of explicit instructional interactions, such as those used in Direct Instruction curricula, for teaching children basic reading and math skills.…

The purpose of this study was to examine parent-teacher congruent perceptions of middle school structures to support parent monitoring of children's behavior. We examined family educational involvement and school's communication and support to families as predictors of congruence, as well as congruence as a predictor of children following school…

Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" (Green, 2008) of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data…

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…

This study examined the cost effectiveness of a 50 lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, ROOTS. The study utilized a randomized block design with 1,251 at-risk students within 138 classrooms randomly assigned to one of two active treatment conditions (small groups of either two…

The purpose of this study was to examine middle school outreach to families about student behavior and its relationship with student school behavior, conduct problems, emotional symptoms, prosocial behavior, as well as school safety. In addition, the role of school implementation of PBIS was examined as a systems-level approach that could promote…

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…
