This study analyzed performance, process, and survey data of eighth graders with learning disabilities (LDs) who took the 2017 National Assessment of Educational Progress (NAEP) digital math test. Compared with students with LDs who did not receive extended time accommodations (ETAs), students with LDs who received and used ETA scored…

Copying a text quickly and accurately is important both in school and in daily life. However, this skill has never been systematically studied, either in children with typical development (TD) or in children with specific learning disabilities (SLD). The aim of this research was to study the features of a copy task and its relationship with other…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

We examined the efficacy of a content acquisition and reading comprehension intervention implemented in eighth-grade social studies classrooms. Using a within-teacher randomized control design, 18 eighth-grade teachers' social studies classes were randomly assigned to a treatment or comparison condition. Teachers taught all their classes…

The purpose of this study was to examine the effectiveness of video-based mathematics instruction for seven middle school students with specific learning disability (SLD), using an augmented reality-based training package. The dependent variable was the percentage of steps students performed correctly to solve each type of mathematics problem. The…

Research has suggested that different strategies used when solving fraction problems are highly correlated with students' problem-solving accuracy. This study (a) utilized latent profile modeling to classify students into three different strategic developmental levels in solving fraction comparison problems and (b) accordingly provided…

A synthesis of the extant research on peer-mediated reading and math interventions for students in regular or alternative education settings with academic difficulties and disabilities in Grades 6 to 12 (ages 11-18) is presented. Interventions conducted between 2001 and 2012 targeting reading and math were included if they measured effects on at…

A majority of reading-related intervention studies aiming to remediate struggling readers' reading outcomes assess student performance immediately following the conclusion of an intervention to determine intervention effects. Few studies collect follow-up data to measure the long-term sustainability of treatment effects. Hence, the aim of the…

This study examined (a) the identification of various reading groups across languages in Chinese (L1) adolescents learning English as a second language (ESL), in terms of their word-reading and reading comprehension skills, (b) overlap in reading group membership across languages, and (c) the performance of the various reading groups on…

This study explores the long-term effects of difficulties in reading and mathematical skills on educational achievement and successful graduation from secondary education as well as the role of special education in successful graduation. Study participants were all 16-year-old ninth graders from one Finnish city (N = 595; 302 females, 293 males)…

We analyzed two nationally representative, longitudinal data sets of U.S. children to identify risk factors for persistent mathematics difficulties (PMD). Results indicated that children from low socioeconomic households are at elevated risk of PMD at 48 and 60 months of age, as are children with cognitive delays, identified developmental delays…

The authors used a large data set (N = 1,011,549) to examine literacy growth over a single school year comparing general education (GenEd) students to three high-risk subgroups: English language learners (ELL), those with a specific learning disability (LD), and those identified as both LD and ELL (LD-ELL) in students in Grades 3-10. The authors…

Rapid automatized naming (RAN) is widely used to identify reading disabilities (RD) and has recently been considered a potential predictor of risk for mathematics learning disabilities (MLD). Here we longitudinally examine RAN performance from Grades K to 8, to view how growth on RAN response time differs for children with RD versus MLD. Across…

This study examines the interaction between the fidelity of implementation of a set of research-based strategies--Collaborative Strategic Reading (CSR)--and outcomes for students with mild to moderate disabilities using data from two nonoverlapping studies in middle school language arts and reading classrooms (Study 1) and middle school social…

The current study examined the development of two effects that have been found in single-digit multiplication errors: relatedness and distance. Typically achieving (TA) second, fourth, and sixth graders and adults, and sixth and eighth graders with a mathematics learning disability (MLD) performed a verification task. Relatedness was defined by a…
