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…

Adolescence is a developmental period that affords both risk as well as enormous opportunity. Ripple effects can extend far and wide and speak to the nuance and complexity in understanding and treating ADHD during the adolescent period. The studies in this special issue provide novel and important insights into the lives of adolescents with ADHD,…

In this article, we review approaches to modeling a connection between spatial and mathematical thinking across development. We critically evaluate the strengths and weaknesses of factor analyses, meta-analyses, and experimental literatures. We examine those studies that set out to describe the nature and number of spatial and mathematical skills…

The purpose of this study was to explore the paths by which word-problem intervention, with versus without embedded pre-algebraic reasoning instruction, improves word-problem performance. Students with mathematics difficulty (MD; n = 304) were randomly assigned to a business-as-usual condition or one of two variants of word-problem intervention.…

This study's purpose was to investigate effects of 3 intervention approaches for building working memory (WM) and improving word-problem solving (WPS). Children with mathematics difficulties (n = 240; 7.51 years [SD = 0.33]) were randomized to 4 conditions: a control group, general WM training with contiguous math practice, WPS intervention…

"Patterning" is a cognitive intervention that is unknown to psychologists, but has nevertheless been taught for half a century in nearly all kindergartens and many preschools in English-speaking countries. Patterning is the understanding that a certain rule governs the sequence of items in a series. At the simplest level, if the series…

We report the results of a pre-registered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no two consecutive problems require the same…

Child-directed speech (CDS), which can help children learn new words, has been rigorously studied among infants and parents in home settings. Yet, far less is known about the CDS that teachers use in classrooms with toddlers and children's responses, an important question because many toddlers, particularly in high-need communities, attend…

The effectiveness of an experimental middle school fraction intervention was evaluated. The intervention was centered on the number line and incorporated key principles from the science of learning. Sixth graders (N = 51) who struggled with fraction concepts were randomly assigned at the student level to the experimental intervention (n = 28) or…

A majority of the challenging words that adolescent readers encounter in school texts are morphologically complex and from the Latinate layer of English. For these words, bound roots carry important meaning, such as the relation between innovative and its bound root, nov, meaning "new." This study investigated the effects of instruction…

We examined the effects of a professional development (PD) system designed to support teachers' use of data-based instruction (DBI) to improve early writing outcomes for children with intensive needs. The PD system, called DBI-TLC, provided "tools" for early writing assessment and intervention, "learning modules" including…

Considerable research has examined interventions that facilitate school readiness skills in young children. One intervention, "Red Light, Purple Light Circle Time Games" (RLPL; Tominey and McClelland, 2011; Schmitt et al., 2015), includes music and movement games that aim to foster self-regulation skills. The present study (N = 157)…

Utility-value (UV) interventions, in which students complete writing assignments about the personal usefulness of course material, show great promise for promoting interest and performance in introductory college science courses, as well as persistence in science, technology, engineering, and mathematics fields. As researchers move toward scaling…

The majority of Tier 2 interventions are facilitated by specialized instructional support personnel, such as a school psychologists, school social workers, school counselors, or behavior consultants. Many professionals struggle to involve parents and teachers in Tier 2 behavior interventions. However, attention to the motivational issues for…

This paper describes the theoretical framework, as well as the development and testing of the intervention, Comprehension Tools for Teachers (CTT), which is composed of eight component interventions targeting malleable language and reading comprehension skills that emerging research indicates contribute to proficient reading for understanding for…
