Learner-centered coaching and feedback are relevant to various educational contexts. Spaced retrieval enhances long-term knowledge retention. We examined the efficacy of Blank Slate, a novel spaced retrieval software application, to promote learning and prevent forgetting, while gathering and analyzing data in the background about learners'…

In basic regression discontinuity (RD) designs, causal inference is limited to the local area near a single cutoff. To strengthen the generality of the RD treatment estimate, a design with multiple cutoffs along the assignment variable continuum can be applied. The availability of multiple cutoffs allows estimation of a pooled average treatment…

Disruptive behavior problems frequently emerge in the preschool years and are associated with numerous, long-term negative outcomes, including comorbid disorders. First Step is a psychosocial early intervention with substantial empirical evidence supporting its efficacy among young children (Walker et al., 2014). The present study reports on a…

The purpose of this study was to examine the effects of a school-wide attendance and truancy intervention and universal procedures (ATI-UP) on student attendance. Student attendance was measured through average daily attendance and the percentage of students who would be considered chronically absent, i.e., missing 10% or more of school. The…

The provision of high-quality early mathematics instruction and intervention is critical to ensure that all students are on track for academic success. Given this, identifying and utilizing assessments that can enable the detection of nonresponse to mathematics instruction is a critical aspect of early intervention. To this end, the current study…

We report here the type of problems and solutions that 38 school teams reported during a randomized wait-list controlled trial of one problem-solving approach (Team Initiated Problem Solving [TIPS]). The experimental results from that analysis are reported elsewhere. The purpose of this article is to summarize companion descriptive data from this…

Data-based problem solving is a hallmark of research-supported practices such as positive behavioral interventions and supports. In this study, we provided members of positive behavioral interventions and supports (PBIS) teams from 38 elementary schools with professional development focused on a research-supported problem-solving model…

This study examined the efficacy of a kindergarten mathematics intervention program, ROOTS, focused on developing whole-number understanding in the areas of counting and cardinality and operations and algebraic thinking for students at risk in mathematics. The study utilized a randomized block design with students within classrooms randomly…

Accelerated Reader™ is a computerized supplementary reading program that provides guided reading instruction to students in grades K-12. It aims to improve students' reading skills through reading practice and by providing frequent feedback on students' progress to teachers. The Accelerated Reader™ program requires students to select and read a…

The purpose of this study is to study the performance of different methods (inverse probability weighting and estimation of informative bounds) to control for differential attrition by comparing the results of different methods using two datasets: an original dataset from Portland Public Schools (PPS) subject to high rates of differential…

This study evaluated the efficacy of the Preschool First Step (PFS) to Success early intervention for children at risk for attention deficit hyperactivity disorder (ADHD). PFS is a targeted intervention for children 3-5 years old with externalizing behavior problems and addresses secondary prevention goals and objectives. As part of a larger…

The adoption of the Common Core State Standards for Mathematics (CCSSM, 2010) in 46 states has raised the mathematical proficiency bar for U.S. students. The advent of these new standards is at a time when the body of empirical evidence on the negative consequences of early and persistent difficulties in mathematics is clear, compelling, and…

This study used a randomized controlled trial design to investigate the ROOTS curriculum, a 50-lesson kindergarten mathematics intervention. Ten ROOTS-eligible students per classroom (n = 60) were randomly assigned to one of three conditions: a ROOTS five-student group, a ROOTS two-student group, and a no-treatment control group. Two primary…

The purpose of this study was to document the design, classroom implementation, and effectiveness of interactive online units to enhance science learning over 3 years among students with learning disabilities, English learners, and general education students. Results of a randomised controlled trial with 2,303 middle school students and 71…
