This study aims to classify subtypes of mathematics disability (MD) using a novel classification method, cognitive diagnostic models (CDMs), and examine whether domain-general skills, namely, linguistic, working memory, and spatial skills, were related to the identification of the subtypes. Participants were 454 children (246 boys; age: M ± SD =…

Although the Texas economy is racing ahead at full speed, state K-12 education has stalled. One major obstacle has been the claim by opponents of school choice in Texas that giving families more education options via education choice policies would harm or even destroy rural district schools. These concerns, even if understandable, are not based…

This study aims to measure the impact of 95 Percent Group's Phonological Awareness Lessons (PA Lessons), an intervention program designed primarily for Tier 2 or 3. The study is a replication of Schechter & Lynch (2023) research conducted in the same medium-sized school district, Val Verde Unified School District, in California during the…

Background: Early numeracy interventions including basic arithmetic are crucial for young students at risk for early mathematics difficulties (MDs), yet few studies have evaluated numeracy interventions in second grade with a randomized controlled design. Aim: This pre- and post-test randomized controlled study evaluated the effects of an…

The purpose of this study was to examine how the implementation of the Wilson's Language Training program, Fundations, influences the reading growth of first-grade graders. Reading proficiency at the school in this study was quite low at six percent. During the intervention, emphasis was placed on phonemic awareness. The Wilson's Fundations…

Running two separate two-stage randomized trials, we implement and test three variants of a small group instruction intervention aimed at improving mathematics competencies for the 20% lowest achievers in mathematics in grades 2 and 8 in Danish public schools. We calculate immediate impacts on math competencies as well as impacts in the medium…

We propose a novel estimator for use in a fuzzy regression discontinuity setting. The estimator can be thought of as extrapolating the traditional fuzzy regression discontinuity estimate or as an observational study that adjusts for endogenous selection into treatment using information at the discontinuity. We show that it can be motivated as…

We evaluate the effects of grade retention on students' academic, attendance, and disciplinary outcomes in Indiana. Using a regression discontinuity design, we show that third-grade retention increases achievement in English Language Arts (ELA) and math immediately and substantially, and the effects persist into middle school. We find no evidence…

Children with low performance in early numeracy are at risk of facing learning difficulties in mathematics, but few trials have examined how this can be ameliorated. A total of 120 first-grade children (M[subscript age] = 6.4 years) were randomly assigned to an intervention or a control condition. The 14-week intervention targeted early numeracy…

The aim of the research is to identify the peculiarities of building reading skills in junior schoolchildren with ASD. The study involved the use of parent questionnaire survey to confirm the diagnosis of ASD (the Social Communication Questionnaire, SCQ), diagnosis of reading skills (the Standardized Assessment of the Reading Skills (SARS), Test…

This study was designed to examine whether there is a significant difference in the English Language Arts and mathematics achievement of third, fourth, and fifth-grade students enrolled in Priority Schools in South Carolina. In an effort to provide a quality education by way of improving state standardized assessments results, nation-wide many…

Genetic studies show that children's reading achievement is in part genetically influenced, and intervention studies show that reading achievement can be increased by environmental interventions. However, correlational and mean-level analytic strategies are rarely integrated into achievement research, potentially leading to misinterpretation of…

Students in Title 1 school districts continue to fall far behind their peers academically in comparison to neighboring suburban districts. School reform has unsuccessfully attempted to improve test scores by consistently changing reading curriculums and mandating the use of various resources that fail when implemented. Struggling school districts…

In the wake of the COVID-19 pandemic, educational systems worldwide have faced unprecedented challenges, particularly concerning the support of students based on traditional face-to-face instruction. This study focused on the concerns surrounding 2nd grade students at LEA and DRA, two urban elementary schools, who have faced multiple layers of…

Identifying and supporting students in early elementary grades with low literacy achievement is critical to help them achieve grade-level proficiency and stay on track academically. "Reading Recovery"® is an intervention that provides one-on-one tutoring to students in grade 1 with low literacy achievement. This supplemental program aims…
