  • Purposeful Practice Opportunities

    Open AccessTasia Brafford, Christian T Doabler et al.ARTICLELearning Disabilities Research &…2026

    Although practice is essential for academic development, questions remain regarding how much and what kinds of practice best support early learners. To examine the role of practice in developing mathematical proficiency, we analyzed rates of guided and independent practice opportunities provided in a kindergarten mathematics intervention for 880 students with mathematics difficulties (MD) across 255 groups. Results indicate that (a) students’ ini…

  • Optimizing Assessment Thresholds of a Computer Gaming Intervention for Students with or at Risk for Mathematics Learning Disabilities

    Open AccessSam Choo, Jechun An et al.ARTICLEEducation Sciences2025

    Students with mathematics learning disabilities often have difficulties in adding whole numbers. Such difficulties are evident in both response time and accuracy, but the relationship between accuracy and response time requires further consideration, especially in the context of technology-based interventions and assessments. In this article, we apply a novel approach using the drift-diffusion model to examine potential trade-offs and find balanc…

  • Early Parenting Effects on Childhood Delay of Gratification and Adolescent Allostatic Load

    Open AccessHeather Leonard, Atika Khurana et al.ARTICLEChildren2025

    Background/Objectives : Early parenting can influence child self-regulatory skills, which are in turn linked to allostatic load (AL)-a predictor of future morbidity and mortality. However, this mechanistic pathway from early parenting to later AL has not been tested using longitudinal data. Methods : We analyzed longitudinal data ( N = 1364) from the Study of Early Child Care and Youth Development to examine relationships between early childhood …

  • Examining the relations between interventionists' use of classroom management and student mathematics gains within a Tier 2 kindergarten mathematics intervention

    Open AccessJessica Turtura, Marah Sutherland et al.ARTICLEPsychology in the Schools2024

    Effective classroom management is critical to supporting student learning and success in school. However, little research has focused specifically on the impact of classroom management on student mathematics achievement, especially in the early elementary grades or in a small group (i.e., Tier 2) context. To address this need we investigated the relationship between classroom management and student mathematics achievement within the context of RO…

  • Proficiency With Number Concepts and Operations

    Open AccessChristian T Doabler, Ben Clarke et al.ARTICLEJournal of Learning Disabilities2024

    Conceptual replications are part and parcel of education science. Methodologically rigorous conceptual replication studies permit researchers to test and strengthen the generalizability of a study’s initial findings. The current conceptual replication sought to replicate the efficacy of a small-group, first-grade mathematics intervention with 240 first-grade students with mathematics difficulties in a new geographical region. Participating studen…

  • Examining Interactions Across Instructional Tiers

    Open AccessMarah Sutherland, Taylor Lesner et al.ARTICLEJournal of Learning Disabilities2023

    High-quality Tier 1 instruction is frequently conceptualized as the “foundation” for other tiers of intervention within multitiered systems of support (MTSS) models. However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness. The purpose of this study was to examine Tier 1 predictors, or “quality indicators,” of differential responsiveness to Tier 2 mathematics intervent…

  • Promoting understanding of measurement and statistical investigation among second-grade students with mathematics difficulties

    Open AccessChristian T Doabler, Ben Clarke et al.ARTICLEJournal of Educational Psychology2022

  • Examining congruence in parent–teacher perceptions of middle school supports for students and families

    Open AccessS Andrew Garbacz, Rachel T Santiago et al.ARTICLEPsychology in the Schools2021

    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 rules and expectations. Participants were 415 teachers and 5003 parents across 40 public middle school…

  • Using Direct Observation to Document “Practice-Based Evidence” of Evidence-Based Mathematics Instruction

    Open AccessChristian T Doabler, Ben Clarke et al.ARTICLEJournal of Learning Disabilities2021

    Implementation of evidence-based practices (EBPs) is paramount to students’ development of mathematics proficiency. This study investigated “practice-based evidence” of interventionists’ actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a federally funded efficacy trial involving a Tier 2 first-grade mathematics intervention to examine whether the quantit…

  • Kindergarteners at Risk for Severe Mathematics Difficulties

    Open AccessChristian T Doabler, Ben Clarke et al.ARTICLEJournal of Learning Disabilities2021

    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 improved from a category of high MD risk (i.e

  • Patterns of early adult work and postsecondary participation among individuals with high-incidence disabilities

    Open AccessChristopher Murray, Derek Kosty et al.ARTICLEDevelopmental Psychology2021Citada por: 3

    Interest in the pathways young people take from high school to early adulthood indicates that participation in early employment and postsecondary education facilitates long-term independence, agency, and career stability (Eliason et al., 2015; Shanahan et al., 2002). Although many adolescents with disabilities do not participate in these early adult experiences at rates commensurate with their normative peers, the overall structure, timing, and p…

  • Profiling adjustment among postsecondary students with disabilities

    Christopher Murray, Allison Lombardi et al.ARTICLEJournal of Diversity in Higher…2014Citada por: 1Referencias: 3

    The current investigation examines profiles of postsecondary adjustment among college students with disabilities. Students’ self-perceptions of practical gains, personal gains, educational gains, their overall satisfaction with postsecondary school, and their college GPA were subjected to a latent profile analysis. Results indicated that students fell into 1 of 3 profiles (i.e., poorly adjusted, average adjusted, or highly adjusted) but were over…
