  • The Role of Instructional Design in the Delivery of Early Science Instruction

    Open AccessSteven A Maddox, Jenna A Gersib et al.ARTICLERemedial and Special Education2025

    A critical tenet of education research is establishing what works. Another is exploring theorized mechanisms of change to help ascertain why academic programs work, for whom, and under which conditions. In other words, unpacking the black boxes of academic programs. This study explored the quality of teachers’ facilitation of (a) scientific investigations and (b) science discourse during and after the implementation of a systematic, explicit seco…

  • A Synthesis of the Conceptualization and Measurement of Implementation Fidelity in Mathematics Intervention Research

    Open AccessSamantha E Bos, Sarah R Powell et al.ARTICLEJournal of Learning Disabilities2023

    In intervention studies, high rates of implementation fidelity are important markers of a study’s success; however, the definition of implementation fidelity is both complex and dynamic. In this synthesis, we examined the dimensions of implementation fidelity measured and reported in 99 studies in which researchers utilized a mathematics intervention for elementary students (i.e., Grades 1–5). We examined implementation fidelity following recomme…

  • Efficacy of a Second-Grade Science Program

    Open AccessChristian T Doabler, William J Therrien et al.ARTICLERemedial and Special Education2021

    This study, which was reviewed through the Registered Report process, examined the initial efficacy of the Scientific Explorers program (Sci2) on second-grade students’ science achievement. Sci2 is grounded in the growing body of empirical research on science instruction, embedding principles of explicit instruction within a guided inquiry-based design framework. Eighteen second-grade classrooms were randomly assigned to treatment or control cond…

  • 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
